[0025] Combine the following Figure 1 A PVT thermal power generation system and a data center provided in the embodiments of the utility model are described.

[0026] The present embodiment provides a PVT heat collection power generation system, comprising: a PVT component 1, a heat pump host 2, a photovoltaic and energy storage integrated machine 3 and a storage battery 4.

[0027] Among them, the photovoltaic and storage integrated machine 3 is electrically connected to the PVT component 1, the battery 4 and the heat pump host 2 respectively.

[0028] That is to say, during the day or when the lighting conditions are good, the PVT component 1 is used for photovoltaic power generation and heat generation at the same time. The generated electric energy is converted into AC power by the photovoltaic storage integrated machine 3 and transmitted to the heat pump host 2, or fed to the mains power grid to supply power to the power supply terminal.

The heat energy generated by the PVT component 1 heats the working fluid flowing out of the heat pump main unit 2, and can heat the low-temperature working fluid such as the coolant of the diesel engine group flowing through the PVT component 1 in winter, thereby increasing the working fluid return temperature of the heat pump main unit 2 and improving the energy efficiency ratio of the heat pump main unit 2.

[0031] In some embodiments, a diesel generator set 5 is also included, and the heat pump main unit 2 is provided with a heat exchange device 21. The heat exchange device 21 is connected to the diesel generator set 5 through a pipeline, and the heat exchange device 21 is connected to the circulation pipeline, which can transfer the heat energy of the working fluid after absorbing heat to the coolant in the diesel generator set 5.

[0032] With such an arrangement, when in use, the AC power, photovoltaic power generation or battery 4 can be selected to heat the engine coolant according to the actual application environment, thereby improving the reliability of the heating system for the engine coolant of the diesel generator set 5 and saving energy costs.

[0033] In this embodiment, the heat exchange device 21 includes a heat exchanger, and the heat exchange includes a shell and a heat exchange tube 7. The heat exchange tube 7 is arranged in the shell, and the two ends of the heat exchange tube 7 are respectively connected to the circulation pipeline. The shell is provided with an input port and an output port. The input port is connected to the first end of the engine of the diesel generator set 5 through a first pipe 51, and the first pipe 51 is provided with a first circulation pump; the output port is connected to the second end of the engine through a second pipe 52, wherein the coolant of the engine circulates in the first pipe 51 and the second pipe 52 through the circulation pump.

[0034] With such an arrangement, the coolant in the diesel generator set 5 is pumped into the heat exchanger through the first circulation pump, and the coolant comes into contact with the high-temperature working fluid in the heat exchange tube 7 to absorb the heat of the high-temperature working fluid, which is used to heat the coolant under cold conditions, thereby ensuring the normal operation of the diesel generator set 5, improving the utilization of solar energy by the PVT component 1, and saving energy costs.

[0035] In some embodiments, the circulation pipeline includes a cold pipe 6 and a heat pipe 7, the heat pipe 7 is connected to the first end of the heat exchange tube 7, the cold pipe 6 is connected to the second end of the heat exchange tube 7, the cold pipe 6 is provided with a second circulation pump, the heat pipe 7 and the cold pipe 6 are respectively connected to the PVT component 1, and the PVT component 1 is used to heat the working fluid in the cold pipe 6 and reflux it to the heat exchange tube 7 through the heat pipe 7 to heat the coolant.

[0036] Optionally, the heat exchange tube 7 is a serpentine tube, which is used to increase the contact time and contact area between the heat exchange tube 7 and the coolant, thereby improving the heating effect on the coolant.

The PVT component 1 is also provided with a working fluid inlet and a working fluid outlet connected to the microchannel plate core. The working fluid inlet is connected to the cold pipe 6, and the working fluid outlet is connected to the heat pipe 7.

[0039] Such an arrangement enables the PVT component 1 to exchange heat with the working fluid in the circulation pipeline. When the working fluid passes through the microchannel plate core in the PVT component 1, the heat can be fully absorbed. While the temperature of the working fluid itself increases, the photovoltaic panel can also be cooled.

[0040] Specifically, the PVT component 1 also includes a frame, and the photovoltaic panels and the microchannel plate core are both arranged in the frame. The frame is provided with a working fluid inlet and a working fluid outlet.
