“…To study the impact of this cooling approach, the performance of a CPV receiver composed by 6 strings of 8 PV cells in series [8] is predicted when submitted to an average solar concentration (C) of 600 suns and a non-uniform illumination profile (Figure 3; [7]). Two cooling configurations are compared: cooled by conventional microchannels versus cooled by the proposed matrix of microfluidic cells with individually variable coolant flow rate.…”

“…Some works [6] have shown the capacity of improved microchannel cooling schemes to obtain, through an adequate design, uniform temperature profiles when submitted to uniform and nonuniform heat flux distributions. Nevertheless, the heat flux distribution on a CPV receiver is non-uniform and time dependent [7]. As a consequence, cooling devices with constant and uniform flow rate distributions are overly conservatives and lead to non-uniform temperature distributions and oversized pumping powers.…”

“…Temperature non uniformities increase the mismatch losses and mechanical stresses throughout the receiver, which causes reliability losses [8]. Furthermore, the pumping power needed to decrease the PV cells temperature and, therefore, to increase the PV efficiency, must be balanced with the PV output in order to find the optimum working point [7].…”

Abstract. Temperature non uniformities of the CPV receivers lead to mismatch losses. In order to deal with this issue, a cooling device, formed by a matrix of microfluidic cells with individually variable coolant flow rate, has been developed. This device tailors the distribution of the heat extraction capacity over the CPV receiver to the local cooling needs in order to reduce the temperature non uniformities with respect to microchannel devices when submitted to uniform or non-uniform illumination profiles. At equal average temperature of the CPV receiver, power generation applying the matrix of microfluidic cells with individually variable coolant flow rate is 9.7% higher than the one with conventional microchannel technology.

“…Generally, there are various cooling methods for the HCPV system in the literature, such as the passive air cooling [5]- [9], active air cooling [10], water cooling [11], [12], directly-immersed cooling [13], heat pipe cooling [14], micro-channel cooling [15], [16], jet impingement cooling [17], and Peltier effect cooling [18], [19]. In consideration of the reliability of cooling device, the passive air cooling may be the most practical cooling solution for the HCPV system.…”

Abstract-The major issue related to the passive air cooling technology for high concentration photovoltaic (HCPV) module is that their heat dissipation efficiencies highly rely on the ambient temperature and wind speed. It may not provide enough cooling for solar cells causing the malfunction of HCPV module under the worst case scenario, i.e., high ambient temperature and no wind condition. In this study, a novel passive air cooling device, named as Solar Enhanced Passive Air Cooling System (SEPACS), was proposed. To verify its performance advantage over conventional aluminum plate heat sink, a three dimensional model was developed in the CFD software. Numerical comparative analysis shows that the SEPACS can keep cell temperature under 75 o C when the concentration ratio reaches to 700, while solar cells cooled by conventional aluminum plate heat sink would be overheated at same concentration ratio.

“…However, the thermal management of solar cells is an important issue need to be dealt with. Significant researches have been dedicated to cool HCPV system as reviewed in literatures [1][2][3][4][5]. It has been shown that the low system thermal resistance was difficult to satisfy because of the presence of traditional wall resistance between solar cells and heat sinks with conventional cooling approaches.…”

Abstract:In order to solve the heat dissipation problem of densely-packed solar cells in high concentration photovoltaic (HCPV) system, a new cooling method of using silicon oil directly immerse the solar cells was proposed. The heat transfer performance of silicon oil immersion cooling the densely-packed solar cells with and without fin structure was investigated through experiment and simulation methods. The results of heat transfer performance of solar cells without fin structure showed that the simulated data was consistent well with data of experiment and the temperature could be lowered down in the operation range of solar cell. Furthermore, the heat transfer performance of solar cells with fin structure was researched using the model under different silicon oil inlet temperatures, inlet flow rates and the flow pressure drop was measured. The results indicated that the solar cells temperature declined and distributed well with silicon oil inlet flow rate increasing but the solar cells temperature raised linearly with silicon oil inlet temperature increasing. The optimized parameters of cooling receiver with fin structure were that: height of fin was 14 mm, number of fin was 50 and the thickness of substrate was 1.5 mm, with which the large amount of heat of densely-packed solar cells under high concentration ratio could be well controlled and make sure the power generation of HCPV system was high efficient.
