Description

Technical Field

[0001] The present invention relates to the field of vehicle-mounted refrigeration equipment, and in particular to a horizontal compressor, a compressor exhaust heating method and a new energy vehicle. Background Art

[0002] For the compressor in the car, when the compressor is in the heating mode of the heat pump air conditioning system, the cabin temperature is low due to the low ambient temperature in winter, and the ordinary heat pump system cannot quickly increase the temperature in the car, the waiting time is long, and the heating efficiency cannot meet the user's needs. The existing technology provides some solutions, but they all have various disadvantages.

[0003] 1. The solution of patent CN110836553A is to shorten the indoor heating time and improve the heating efficiency. A refrigerant heater is added in the middle of the pipeline connecting the compressor exhaust port and the oil separator. The refrigerant heater includes two types of electromagnetic heating refrigerant heaters, PTC refrigerant heaters and three types of refrigerant heaters with thick film heating components. The refrigerant heater with thick film heating component contains: microchannel heat exchanger, resistance heating component (including resistance heating layer and power module). The power module is connected to the resistance heating layer, and the resistance heating layer is arranged on the microchannel plate. The electromagnetic heating refrigerant heater contains a microchannel heat exchanger, a heat conduction plate, a first insulation plate, a second insulation plate, and an electromagnetic heating coil. The PTC refrigerant heater contains a microchannel heat exchanger, a first PTC heating component (including a first PTC heating element and a first heating power supply), and a second PTC heating component (including a second PTC heating element and a second heating power supply). This solution is conducive to improving the heating speed of the heat pump system and greatly improving the comfort of the system. However, this solution needs to be set up in the entire heat pump system, and additional equipment, pipelines, and power supplies need to be added, which is costly. Moreover, for vehicle air-conditioning systems, the installation space and location are extremely limited, and the applicability is poor.

[0004] 2. The heating device in patent CN201428579Y includes an electromagnetic induction heating coil, which is characterized in that the electromagnetic induction heating coil is wound around the compressor casing near the air intake port, the output end of the high-frequency power frequency conversion controller is electrically connected to the electromagnetic induction heating coil, and the input end of the high-frequency power frequency conversion controller is electrically connected to the temperature sensor, and the temperature sensor is connected to the compressor intake pipe. This solution can increase the heating power of the compressor and meet the heating needs. However, this solution sets the heating device on the compressor casing near the air intake port, which can increase the internal temperature of the compressor. But for an electric compressor, the internal temperature of the compressor cannot be too high, and the controller part needs to dissipate heat. This solution will cause the performance of the electric compressor to decline, and even the failure of the controller will cause the compressor to shut down.

[0005] 3. Patent CN117265852A sets an auxiliary heating device on the compressor housing or around the compressor to directly or indirectly heat the compressor to increase the compressor exhaust temperature. This can improve the heating performance of the compressor. However, the heating scheme for the entire compressor will also lead to problems such as high internal temperature of the compressor, and is not suitable for electric compressors.

[0006] In view of this, the present invention provides a horizontal compressor, a compressor exhaust heating method and a new energy vehicle. Summary of the invention

[0081] Figure 2 2 is a cross-sectional view of a second horizontal compressor of the present invention. Figure 2As shown, the second horizontal compressor of the present invention includes: a cavity formed by a middle shell 4 and a rear shell 6, a front shell 2, a heating component 10 and a heat dissipation sealing baffle 11.

Figure 1 The structure is different in Figure 2 The second horizontal compressor controls the heating assembly 10 through the compressor controller 14, and no other control modules in the vehicle are needed, which enhances the structural integration of the multifunctional horizontal compressor and reduces the difficulty of installation and layout.

[0082] In a preferred embodiment, the heat dissipation sealing baffle 11 is in surface contact with the heating assembly 10 to transfer heat to the exhaust chamber, but the present invention is not limited thereto.

[0083] In a preferred embodiment, the heat dissipation sealing baffle 11 is provided with an annular sealing edge 17 protruding toward the end face 18 on one side thereof, and the annular sealing edge 17 is provided with a sealing groove filled with a sealing ring 1 that seals with the end face 18, but the present invention is not limited thereto.

[0088] The present invention sets a heating device near the compressor exhaust port and the exhaust cavity, and the heat generated by the heating device is transferred to the refrigerant gas in the compressor exhaust cavity through heat conduction and convection heat transfer process, and the refrigerant absorbs heat and heats up, and condenses and releases heat at the condenser. Compared with the case where the heating device is not set, the present invention can provide additional sensible heat transfer of the refrigerant, greatly improving the heating capacity of the heat pump air conditioning system. At the same time, the structure is simpler and does not increase the burden of the system structure. The heating device in the present invention includes a heating component, a thermal insulation material, etc. The heating component can be a PTC heating component, a thick film heating component, etc. In the present invention, the heating device is set in the inner cavity, and the heating component connector is connected from the outside of the front shell to power and control it. A heat dissipation sealing baffle and a sealing ring are set near the inner cavity side of the heating component to seal the heating component. The ribs of the heat dissipation sealing baffle can greatly increase the heat exchange area, and then the heat of the heating device can be more efficiently transferred to the refrigerant gas. The heating device set in the exhaust cavity inside the front shell of the compressor needs to be additionally treated with oil, water and refrigerant isolation.

[0089] In one variation, the heating device is disposed in the inner cavity, and the wiring of the heating component is disposed in the entire housing of the compressor, which is separated from the internal high-pressure refrigerant and the outside air, and finally connected to the compressor controller area of ​​the rear shell, and is powered and controlled by the compressor controller. A heat dissipation sealing baffle and a sealing ring are disposed on the heating component near the inner cavity side to seal the heating component. The ribs of the heat dissipation sealing baffle can greatly increase the heat exchange area, thereby more efficiently transferring the heat of the heating device to the refrigerant gas. In addition, the heating device disposed in the exhaust cavity on the inner side of the front shell of the compressor is subject to additional oil, water, and refrigerant isolation treatments.

[0107] S8: The system is shut down and the heating device is shut down at the same time.

[0108] The present invention has the following technical advantages:

[0109] 1. Simple structure, saving installation space.

[0110] 2. High thermal efficiency, which can significantly improve the heating performance of the system.
