The invention discloses a heat pipe solar thermal collector. The heat pipe solar thermal collector comprises a heat exchange tube body, a penetration sleeve and at least one heat pipe. The heat exchange tube body is provided with a tube wall and an accommodation space enclosed by the tube wall. An open groove not penetrating through the tube wall is formed on one end face of the tube wall. First threads are arranged on the inner wall surface of the open groove. At least one through hole communicated with the accommodation space is formed in the open groove. The penetration sleeve comprises a pipe column with a penetration hole. The pipe column is provided with second threads, and is connected into the open groove through the threads. Each heat pipe comprises a body and working fluid in the body. One end of each heat pipe penetrates through the penetration hole and the corresponding through hole to be arranged in the accommodation space. The heat of the heat pipes can be taken away by cold water flowing into the heat exchange tube body to realize the heat exchange of the heat pipes by the phase changes of the working fluid. Therefore, an assembly mode for the thermal collector is simplified, and a thermal collection effect is improved.

The 3D solar light focusing and heat collecting apparatus includes support frame, sunlight reflecting condenser, light spot receiving heat absorber. The sunlight reflecting condenser includes at least two parts, the horizontal condenser with north-south axis and the vertical condenser connected to the north end of the horizontal condenser. The double-panel heat absorber is set in the center of the horizontal condenser perpendicularly and has its north end connected to the vertical condenser perpendicularly. The said fixed structure can solve the problem of light focusing and heat collecting to the moving sun. The present invention has simple structure, low cost, high heat collecting efficiency and other advantages.

The invention discloses a combined heating and cooling solar-assisted heat pump system. The system comprises a solar heat collection system and a heat pump system, wherein the solar heat collection system comprises a micro-channel flat plate heat pipe heat collector, a connecting pipeline, a water tank and a circulating water pump; the heat pump system comprises an evaporator, a reversing valve, a compressor, a condenser and a throttling device; the micro-channel flat plate heat pipe heat collector is connected with the water tank and is connected with the circulating water pump through the connecting pipeline; the circulating water pump is connected with the water tank; the evaporator is arranged in the water tank; one end of the evaporator is connected with the compressor through the reversing valve; the compressor is connected with the throttling device through the condenser; the throttling device is connected with the other end of the evaporator which is placed in the water tank. The micro-channel flat plate heat pipe heat collector can be laid on the outer surface of a normal building wall (or balcony) or used in place of the normal building outer wall (or balcony), so the building energy consumption can be greatly reduced and zero energy consumption (or close to zero energy consumption) can be realized, and the utilization rate of renewable energy sources (solar energy) is increased.

The invention discloses a solar energy collection focusing tracking driving mechanism which is applied to slot solar thermal power generation engineering. The mechanism is characterized by comprising a flange shaft, connection rods, pin rolls, a single piston hydraulic cylinder, a driving mechanism support frame, a parabolic condenser main shaft, and a parabolic condenser main shaft support frame. The flange shaft is concentrically connected with the parabolic condenser main shaft; the connection rods are connected with the piston hydraulic cylinder; and the pin rolls are connected with a connection piece and the hydraulic cylinder. The single piston hydraulic cylinder mainly comprises a cylinder barrel and a piston rod. Only one end of the single piston rod is provided with the piston rod, oil is pressed or returned by an oil pump, the piston rod is pushed to be extended or contracted from the cylinder barrel slowly, then the connection piece swings, and finally the flange shaft is rotated, so that a slot paraboloid is driven to rotate. The solar energy collection focusing tracking driving mechanism has a simple structure, rotates stably and is large in load capacity, and is usedas a slot heat collection paraboloid focusing tracking mechanism structure which has the characteristics of reliability and stability, and can be applied to a large-scale slot solar thermal power station.
