Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, and in particular to a protective device for an air source heat pump. Background Technology

[0002] An air source heat pump is an energy-saving device that uses the reverse Carnot cycle principle to convert low-grade heat energy (such as heat in the air) into high-grade heat energy. Air source heat pumps can efficiently extract heat from the air for heating, cooling, or hot water supply, and are characterized by energy saving and environmental friendliness.

[0003] When an air source heat pump is installed outdoors, a protective device is required to protect the pump body. During pump operation, the protective device needs to be equipped with a heat dissipation mechanism to dissipate heat from the pump body. Currently, most existing protective devices use natural air cooling, which typically involves a fan drawing in outside air and blowing it into the device to dissipate heat from the pump body. However, when the ambient temperature is too high, the outside air temperature will also rise, making natural air cooling insufficient to meet the heat dissipation requirements of the pump body, which can easily lead to overheating and damage.

[0021] Reference Figure 1-5 A protective device for an air source heat pump includes a fixed box 1, a support column 2 fixedly connected to the bottom surface of the fixed box 1, a heat dissipation groove 3 extending through the surface of the fixed box 1, a base frame 4 fixedly connected to the inner wall of the fixed box 1, a heat pump body 5 fixedly connected to the top surface of the base frame 4, a connecting pipe 6 fixedly connected to the inner wall of the fixed box 1 and the connecting pipe 6 being fixedly connected to the inner wall of the heat pump body 5, an air inlet mesh plate 7 fixedly connected to the inner wall of the fixed box 1, and a liquid storage tank 8 fixedly connected to the top surface of the fixed box 1. The liquid storage tank 8 is rectangular and made of metal, which provides stronger cooling performance and facilitates rapid cooling of the air. An air inlet 9 extends through the inner wall of the liquid storage tank 8. A refrigeration mechanism is installed inside the liquid storage tank 8, consisting of a heat-conducting plate 10, a semiconductor cooling chip 11, a fan shroud 12, and a cooling fan 13. Multiple semiconductor cooling chips 11 are arranged facing the front of the liquid storage tank 8. The vertical centerline is symmetrically arranged as an axis of symmetry to reduce the temperature of the coolant and improve the cooling efficiency. The heat-conducting plate 10 is fixedly connected to the inner wall of the liquid storage tank 8, the semiconductor cooling chip 11 is fixedly connected to the inner wall of the heat-conducting plate 10, the fan shroud 12 is fixedly connected to the surface of the liquid storage tank 8, and the cooling fan 13 is fixedly connected to the inner wall of the fan shroud 12 to reduce the temperature of the liquid storage tank 8 and the coolant, facilitating the conduction and cooling of the air. An air inlet assembly is provided inside the liquid storage tank 8, which consists of a fan duct 14, a suction pipe 15, and a fan 16. The fan duct 14 is fixedly connected to the inner wall of the liquid storage tank 8, the air outlet of the suction pipe 15 is fixedly connected to the inner wall of the fan duct 14, and the fan 16 is fixedly connected to the inner wall of the suction pipe 15 and the back of the liquid storage tank 8. The fan 16 is used to drive the cooled air into the fixed box 1, facilitating the rapid heat dissipation and cooling of the heat pump body 5. A rainproof mechanism is provided on the top surface of the fixed box 1, and a door opening and closing assembly is provided on the surface of the fixed box 1.

[0022] Specifically, the rainproof mechanism consists of a support rod 17 and a rain cover 18. The support rod 17 is fixedly connected to the top surface of the fixed box 1, and the inner wall of the rain cover 18 is fixedly connected to the surface of the support rod 17. It is used to protect the fixed box 1 from rain and prevent rainwater from seeping into the fixed box 1.

[0023] Specifically, the door opening and closing assembly consists of a hinge 19, a protective door panel 20, and a door lock 21. The hinge 19 is fixedly connected to the surface of the fixed box 1. The protective door panel 20 is hinged to the fixed box 1 via the hinge 19, and the protective door panel 20 overlaps with the front of the fixed box 1. The door lock 21 is fixedly connected to the inner wall of the protective door panel 20. It is used to open and close the fixed box 1, which facilitates the protection and maintenance of the heat pump body 5.

[0024] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0025] In use: First, unlock the door lock 21 and then rotate the protective door panel 20 through the hinge 19. Fix the heat pump body 5 onto the base frame 4. Connect the inlet and outlet ends of the heat pump body 5 to multiple connecting pipes 6 respectively. After resetting the protective door panel 20 and the door lock 21, the protection of the heat pump body 5 can be performed. In use, the semiconductor cooling chip 11 is activated to absorb and release heat. The heat-absorbing end of the semiconductor cooling chip 11 absorbs heat from the inside of the liquid storage tank 8 through the heat conduction plate 10, thereby reducing the coolant temperature. At the same time, the cooling fan 13 is activated to cool the semiconductor cooling chip 11. The heat dissipation end of the heat exchanger 11 dissipates heat, and the surface temperature of the liquid storage tank 8 is reduced as the temperature of the coolant decreases. The fan 16 is started to draw outside air into the air duct 14 and the liquid storage tank 8 through the suction pipe 15. When the air passes through multiple air inlets 9, it comes into uniform contact with the liquid storage tank 8. The air can be cooled by the heat conduction effect of the liquid storage tank 8. The cooled air enters the fixed box 1 through the air inlet mesh plate 7 and comes into contact with the heat pump body 5, which can perform rapid cooling and heat dissipation. At the same time, heat and air are discharged through the heat dissipation slot 3.

[0026] In summary, the protective device for this air source heat pump, after opening the door assembly, fixes the heat pump body 5 on the base frame 4, connects the heat pump body 5 to multiple connecting pipes 6, and resets the door assembly to perform the protective work for the heat pump body 5. During use, the refrigeration mechanism is activated to reduce the temperature of the coolant and the liquid storage tank 8, and the air intake assembly is activated to drive air through multiple air intake holes 9 to uniformly contact the liquid storage tank 8 for cooling. The cooled air enters the fixed box 1 through the air intake mesh plate 7 to quickly cool and dissipate heat from the heat pump body 5. Heat dissipation is carried out through the heat dissipation slots 3, achieving the goal of facilitating rapid heat dissipation protection of the air source heat pump in high-temperature environments. This avoids the problem that the existing protective device's natural air cooling method cannot meet the heat dissipation requirements of the pump body in high-temperature environments, thus preventing the pump body from easily overheating and being damaged. This device solves the problems mentioned in the background art.
