Problems solved by technology

[0002] When the photovoltaic cell is working, the radiator is generally used to dissipate heat from the photovoltaic cell to ensure the power generation efficiency of the photovoltaic cell. The heat dissipation copper plate is installed on the photovoltaic cell, and then the heat pipe element is inserted in the heat dissipation copper plate. Using the heat dissipation copper plate Transfer heat, and then use the heat pipe principle to dissipate heat and cool down the heat pipe element and the water tank. However, in the process of heat dissipation, the heat pipe and the heat dissipation copper plate need to be fully bonded, and the heat dissipation copper plate will expand and deform due to high heat when transferring heat, resulting in heat dissipation. A gap is easily formed between the contact area between the copper plate and the heat pipe, resulting in insufficient contact between the heat dissipation copper plate and the heat pipe, so that a vacuum environment or air will be formed in the gap between the heat dissipation copper plate and the heat pipe, and the heat conduction efficiency of the vacuum environment and air is poor, resulting in the heat dissipation of the copper plate. The efficiency of heat transfer between the heat pipe and the heat pipe is affected. Therefore, we propose a heat pipe-type concentrating photovoltaic cooling heat collector that can prevent insufficient contact
