Description

Technical Field

[0001] The utility model relates to the technical field of automobile heat pumps, in particular to an automobile two-stage compression heat pump. Background Art

[0002] The automotive heat pump air conditioning system is a system that uses heat pump technology to provide air conditioning and heating functions for the car. The automotive heat pump air conditioning system mainly includes components such as compressor, condenser, expansion valve (or throttle valve) and evaporator. When working, the compressor can increase the pressure and temperature of the refrigerant vapor through compression, compressing the low-temperature and low-pressure refrigerant vapor to a high-temperature and high-pressure state, and then selectively pumping the high-temperature and high-pressure refrigerant to the heat exchanger inside or outside the car through the control of the four-way valve.

[0003] The automotive heat pump air conditioning system uses different energy sources, such as engine heat, electric vehicle battery waste heat or solar energy, to achieve the cooling effect of the car through the coordinated work of components such as compressors, condensers, connecting pipes and evaporators. These systems have significant advantages in energy conservation, emission reduction and improving energy utilization efficiency.

[0004] However, after long-term use, the body of the automobile two-stage compression heat pump will also generate a large amount of heat. When the heat accumulates and cannot be dissipated and cooled for a long time, it may affect the service life of the automobile two-stage compression heat pump. Therefore, it is necessary to cool down the body of the automobile two-stage compression heat pump.

[0005] For this reason, we urgently need to provide a kind of automotive two-stage compression heat pump. Utility Model Content

[0006] The purpose of the utility model is to provide a two-stage compression heat pump for an automobile, so as to solve the problem that the two-stage compression heat pump for an automobile proposed in the above-mentioned background technology will generate a large amount of heat in its body after long-term use. When the heat accumulates and cannot be dissipated and cooled for a long time, the service life of the two-stage compression heat pump for an automobile may be affected.

[0007] To achieve the above objectives, the utility model provides the following technical solutions: an automobile two-stage compression heat pump, comprising a base and a bracket, the bracket being fixedly connected to the top of the base, a heat pump device being arranged on the base, and a heat dissipation device being arranged on the heat pump device.

[0008] The heat pump device includes a compressor, an evaporator, a heat exchanger, and a connecting pipe. The compressor is installed on a bracket, the evaporator is installed on the left side of the compressor, the heat exchanger is installed above the compressor, and the connecting pipe is installed on the evaporator and the heat exchanger.

[0009] A further improvement is that the heat dissipation device includes a liquid storage tank, a micro water pump, a liquid extraction pipe, and a heat dissipation component, the liquid storage tank is installed on the right side of the upper surface of the base, the micro water pump is installed on the top front end of the liquid storage tank, the liquid extraction pipe is installed on the water suction port of the micro water pump and extends into the interior of the liquid storage tank, and the heat dissipation component is installed on the micro water pump.

[0010] A further improvement is that the heat dissipation assembly includes an infusion tube, a connecting tube, an arc-shaped heat dissipation tube, and a return pipe. The infusion tube is installed at the top water outlet of the micro water pump, the connecting tube is fixedly connected to the top of the infusion tube, a plurality of the arc-shaped heat dissipation tubes are fixedly connected to the connecting tube at equal distances, and the return pipe is fixedly connected to the rear end of the arc-shaped heat dissipation tube.

[0011] A further improvement is that the arc-shaped heat dissipation pipe is closely attached to the outer surface of the compressor, one end of the return pipe extends into the interior of the liquid storage tank, and the micro water pump is started to pump the coolant in the liquid storage tank to the interior of the infusion pipe through the pumping pipe, and then flows to the interior of the connecting pipe, and then flows to the interior of the arc-shaped heat dissipation pipe. Because the arc-shaped heat dissipation pipe is closely attached to the outer surface of the compressor, the heat generated by the operation of the compressor is exchanged and cooled. The coolant after heat exchange flows back to the interior of the liquid storage tank through the return pipe, thereby completing the recycling of the coolant.

[0012] A further improvement is that the interior of the liquid storage tank is filled with coolant, and a heat sink is installed on the right outer surface of the liquid storage tank. The heat sink is made of copper alloy. The heat sink made of copper alloy has good heat dissipation performance. The coolant after heat exchange inside the liquid storage tank is cooled by the heat sink to ensure the temperature of the coolant for easy recycling.

[0013] A further improvement is that an air inlet is opened on the left side of the base, a guide box is installed on the top of the air inlet, a cooling fan is installed inside the guide box, and the cooling fan is started to dissipate heat and cool the evaporator.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The automotive two-stage compression heat pump starts the micro water pump to pump the coolant in the liquid storage tank to the inside of the liquid infusion pipe through the liquid extraction pipe, and then flows to the inside of the connecting pipe, and then flows to the inside of the arc-shaped heat dissipation pipe. Because the arc-shaped heat dissipation pipe is close to the outer surface of the compressor, the heat generated by the operation of the compressor is exchanged and cooled. After the heat exchange, the coolant flows back to the inside of the liquid storage tank through the return pipe, thereby completing the circulation of the coolant.

[0016] 2. The automobile two-stage compression heat pump has a heat sink made of copper alloy with good heat dissipation performance. The heat sink is used to cool the coolant after heat exchange inside the liquid storage tank, ensuring the temperature of the coolant for easy recycling. BRIEF DESCRIPTION OF THE DRAWINGS
