“…From the temperature rising simulation results in Figure 9, we approximately calculated the TEC performance parameters, Rm, Km and Sm, for Th = 50°C and the following parameters were obtained: Rm = 0.985Ω, Km = 0.946K/W and Sm = 0.048V/K. Using Equation equation (11), in the first situation,Ta = 298.15K (25°C ), the TEC drive current (I) was defined as 5A, and it was assumed that R1 = R2 = 0.1K/W and T1 = 293.15K (20°C ) at which the pump source can work stably. For the two groups of TEMs with R3 = 0.04K/W, the cooling output of each TEM was Qc1 = 39.5W, and for the other two groups of TEMs with R3 = 0.03K/W, the cooling output of each TEM was Qc2 = 40W.…”

“…However, it requires the connection of an external water cooler which causes the laser to have a large. Forced air cooling, heat pipe cooling, micro-channel cooling and other passive cooling methods can only ensure the temperature of the laser is higher than the ambient environment [11], while in some situations, the temperature of the laser needs to be controlled to be lower than the environment. Thermoelectric cooling, usually considered using the thermoelectric cooler (TEC), has advantages over conventional cooling devices, including being compact in size, having high reliability, no mechanical moving parts, no working liquid, light in weight, being powered by direct current, and easily switching between cooling and heating modes [12].…”

“…Recent studies of thermal management using TECs for lasers have mainly focused on single diode lasers with medium and low output powers, while high output power pump lasers always use the water cooling method to dissipate heat [11], which cannot satisfy the demand for miniaturization. In this paper, an all-fiber laser pumped optical parametric oscillator (OPO) laser was established with a compact thermal control system based on an automatic temperature control circuit, TEMs, cooling fins, axial fans and heat pipes.…”

“…Two TECs were adopted to maintain the temperature of the LD module, and it was observed that precision of the TEC controller impacted the relative stability of the output energy. Wei Zhang et al [11] used a finite-element analysis method to study the performance of a micro semiconductor laser with TEC; the thermal cooling methods on the hot side of TEC were also investigated. Hao Wang et al [17] developed a dynamic thermal model for a tunable laser module with a proportion-integration-differentiation (PID) temperature controller based on finite-element analysis.…”

Tunable mid-infrared lasers are widely used in laser spectroscopy, gas sensing and many other related areas. In order to solve heat dissipation problems and improve the environmental temperature adaptability of solid-state laser sources, a tunable all-fiber laser pumped optical parametric oscillator (OPO) was established, and a compact thermal control system based on thermoelectric coolers, an automatic temperature control circuit, cooling fins, fans and heat pipes was integrated and designed for the laser. This system is compact, light and air-cooling which satisfies the demand for miniaturization of lasers. A mathematical model and method was established to estimate the cooling capacity of this thermal control system under different ambient environments. A finite-element model was built and simulated to analyze the thermal transfer process. Experiments in room and high temperature environments were carried out and showed that the substrate temperature of a pump module could be maintained at a stable value with controlled precision to 0.2 degrees, while the output power stability of the laser was within ±1%. The experimental results indicate that this compact air-cooling thermal control system could effectively solve the heat dissipation problem of mid-infrared solid-state lasers with a one hundred watts level pump module in room and high temperature environments.

The high temperature makes electronic components bear excessive thermal loads, which significantly degrade the performance of devices. The thermal issues in technological applications, such as DNA microarrays and micro-electrothermal systems, have been addressed by using high performance thermoelectric cooler. In this paper, a folded structure of thermoelectric elements with Bi 2 Te 3 -based thin-film superlattices (TFSL) material is proposed. The folded structure makes the minimum thickness of the thermocouples as low as 30 μm. Also, the passing electrical current induced by the thin thickness can be decreased to milliampere order of magnitude from ampere with traditional structure. The temperature difference between the hot and cold sides of thermoelectric cooler (TEC) is improved up to 2-16 times than that of the conventional structure. The proposed structure model agreed well with simulation results for relationships between temperature difference and sizes of thermocouples. The presented folded construction with thin-film superlattices materials can provide a viable solution for high-power, as well as high heat flow density device cooling. For state-of-the-art high-performance electronic devices, the generated overloads heat can result in high temperature hot-spots, which will significantly reduce the lifetime of devices. By integrating thermoelectric cooler devices, the peak temperature of these hot-spots can be targeted and eliminated. Compared with the conventional cooling solutions with inefficiency and hulking features, thermoelectric cooler with high cooling capacity and easy integration can apparently improve the performance and reliability of electric devices and optoelectronic components.1-3 Moreover, due to the absence of moving parts or working fluids, thermoelectric cooling technology has been used practically in fields of aerospace, 4,5 medicine, 6,7 vehicles 8,9 and instrumentation. [10][11][12] Compared with conventional thermoelectric materials, many novel thermoelectric mechanisms and technologies such as superlattices and quantum dots have been investigated recently.13-15 For superlattices materials, every layer contains several or dozens of atoms. Such the ultra-short-period superlattices can offer tremendous quantumconfinements and interface scattering than bulk material. Using quantum-confinement effects, an enhanced density of states close to the Fermi energy can be obtained. With the same effect, a ZT of 0.9 at 300 K has been reported in PbSe 0.98 Te 0.02 /PbTe quantum-dot structure. 16 In addition, the higher area versus volume ratio, lower feature size of thin-film superlattices and the enhanced of phonon scattering reduce the phonon mean free path of carriers, which in turn reduces the thermal conductivity.17 Furthermore, ultra-short-period superlattices offer significantly higher in-plane carrier mobility, therefore, an enhanced carrier mobility in monolayer-range superlattices is effectively carried out in the cross-plane direction for certain superlattices. 1 Base on the above a...

The active battery thermal management system is critical for the security of electric vehicles. In this article, a novel battery thermal management system and the control strategy based on thermoelectric cooling are proposed. A coupling model between the thermoelectric cooler and the battery pack is built by MATLAB/Simscape software. The model precision is verified through the experimental bench test, with a maximal deviation of 0.56 °C (the accuracy of the temperature sensor is ±0.1 °C). Further, a battery thermal management strategy with model predictive control (MPC) is proposed. In the results, it is elucidated that the MPC strategy has a superiority over the proportional‐integral‐derivation (PID) strategy in both the response time and energy consumption. Notably, the MPC strategy achieves a 35.17% reduction in response time and a 28.65% decline in energy consumption under a constant current of 2 C. Furthermore, during the variable H_N_U_F cycle conditions, the control effects are also evident, with an overshoot diminution of 12.2%, a maximum temperature error decrease of 23.85%, a response time reduction of 31.15%, and an energy utilization decline of 31.85%. In this study, a novel perspective in advancing battery thermal management systems through the application of thermoelectric cooler is provided.
