For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium.

[0043] See Figures 1 to 3 As shown, the embodiment of the present application provides a compressor heating device a, including: a main body member 1, a water inlet nozzle 2, and a water outlet nozzle 3. The main body member 1 encloses a receiving space 4 for accommodating a part of the compressor 5. One surface of the main body member 1 located in the receiving space 4 has a concave surface that fits the compressor 5. A water flow channel is provided inside the main body member 1. The water inlet nozzle 2 is connected to the main body member 1, and the water inlet nozzle 2 communicates with one end of the water flow channel. The water outlet nozzle 3 is connected to the main body member 1, and the water outlet nozzle 3 communicates with the other end of the water flow channel.

[0044] The compressor heating device a of the present application can be arranged on the periphery of the compressor 5, that is, the compressor 5 can pass through the receiving space 4. The compressor heating device a can be connected to the cooling pipeline 7 of the battery pack, so that the coolant heated by the battery or the heater can be introduced into the compressor heating device a to heat the housing of the compressor 5, increase the refrigerant pressure, avoid the oil stratification phenomenon caused by low temperature, and extend the service life of the compressor 5.

[0045] In some possible implementation schemes, the main body member 1 is connected to the compressor 5 in any one or more of the following ways:

[0046] In the first scheme, the main body member 1 is connected to the compressor 5 through a fastener. The fastener can be a bolt, and one end of the bolt passes through the lug on the main body member 1 and is threadedly connected to the corresponding thread groove on the housing of the compressor 5.

[0047] In the second scheme, the main body member 1 is snap-fixed to the compressor 5. Assembly structures that can be snap-fixed to each other can be provided on the main body member 1 and the compressor 5, which is convenient for snap-fixing the two.

[0048] In the third scheme, the main body member 1 is bonded to the compressor 5. The main body member 1 is bonded to the compressor 5 with a colloid. The structure is relatively simple, and the colloid can seal the gap between the main body member 1 and the compressor 5, which is beneficial to heat exchange.

[0049] In some possible implementation schemes, a heat conduction layer is provided between the concave surface and the compressor 5. The heat conduction layer seals the gap between the concave surface and the compressor 5, which is beneficial to heat conduction and improves the heat exchange efficiency.

[0050] The heat-conducting layer may include a heat-conducting adhesive layer that covers the concave surface, and the concave surface is connected to the compressor 5 through the heat-conducting adhesive layer. The setting of the heat-conducting adhesive layer not only realizes the connection between the compressor 5 and the compressor heating device a, but also facilitates heat conduction and improves the heat exchange efficiency.

[0051] In some possible implementation manners, the main body member 1 is an arc-shaped sheet body that extends along the circumferential direction of the compressor 5. The main body member 1 may be annular and sleeved on the compressor 5, or the main body member 1 may be semi-annular and cover the outer surface of the compressor 5.

[0052] In some possible implementation manners, the main body member has a convex surface spaced from the concave surface, and both the water inlet nozzle 2 and the water outlet nozzle 3 are arranged on the convex surface.

[0053] In this implementation manner, the concave surface and the convex surface are two surfaces on both sides of the main body member in the thickness direction. The concave surface is in contact with the compressor 5, while the convex surface faces away from the compressor 5. The water inlet nozzle 2 and the water outlet nozzle 3 are arranged on the convex surface and will not interfere with the compressor 5, and the setting position is more reasonable.

[0054] In some possible implementation manners, the water flow channel extends in a bent manner multiple times along the length direction or the circumferential direction of the compressor 5. The water flow channel has a bent extension structure with a large effective area, which increases the contact area between the water flow and the compressor 5.

[0055] The main body member 1 includes an arc-shaped main body 11 and two arc-shaped end strips 12. The arc-shaped main body 11 has a sandwich cavity and two arc-shaped ports 111 communicating with the sandwich cavity. The two arc-shaped end strips 12 are respectively arranged at both ends of the arc-shaped main body 11, and the two arc-shaped end strips 12 respectively close the corresponding arc-shaped ports 111. The arc-shaped end strips 12 can be welded to the arc-shaped main body 11. A plurality of partition ribs are arranged in the arc-shaped main body 11, and each partition rib divides the sandwich cavity to form a water flow channel that bends multiple times. The structure and production process of the main body member 1 of the heating device in this application can refer to the existing water-cooled plate, the difference being that the main body member 1 in this application is bent, while the ordinary water-cooled plate is flat.

[0056] Optionally, the arc-shaped main body 11 is an integrally formed part, and the main body member 1 can be made by an extrusion process. For example, it can be directly extruded into an integral part by an aluminum extrusion process.

[0057] An embodiment of the present application also provides a battery system, including: a battery pack, a cooling pipeline 7, a cooling unit, and the above-mentioned compressor heating device a. The cooling pipeline 7 is connected to the battery pack. The cooling unit can adopt an air-conditioning unit, which has a compressor 5 and a heat exchanger (evaporator or condenser). The heat exchanger has a heat exchange channel. The cooling pipeline 7 communicates with the heat exchange channel. The compressor heating device a can be connected to the side of the outlet of the cooling pipeline 7 where the battery pack is located. The water inlet nozzle 2 and the water outlet nozzle 3 of the compressor heating device a are both connected to the cooling pipeline 7. The cooling pipeline 7, the battery pack, the heat exchange channel of the heat exchanger, and the water flow channel of the compressor heating device a can form a circulating water path. The main body 1 is connected to the compressor 5.

[0058] It should be noted that the battery system may include a parallel pipeline 8. The cooling pipeline 7 has a switching section 71. The parallel pipeline 8 can be connected in parallel with the switching section 71. The compressor heating device a is provided on the parallel pipeline 8. The upstream pipe sections of the cooling pipeline 7 and the parallel pipeline 8 are connected by a three-way valve 6. The three-way valve 6 can selectively connect the upstream pipe section of the switching section 71 to the switching section 71 or the parallel pipeline 8.

[0059] In a low-temperature environment, when the battery pack is charging or in a driving condition, when the temperature of the battery pack is relatively high, the controller of the battery pack can request the water-cooling unit to refrigerate. The water-cooling unit monitors the ambient temperature / refrigerant pressure through a temperature / pressure sensor to confirm whether the compressor 5 is suitable for operation. If the compressor 5 is not suitable for operation, the compressor 5 stops running, the water pump on the cooling pipeline 7 operates normally, the three-way valve 6 switches to the parallel pipeline 8 to conduct, and the switching section 71 is closed. The battery pack heats the circulating coolant. When the coolant passes through the compressor heating device a, it heats the housing of the compressor 5. When the refrigerant pressure of the compressor 5 rises to a suitable working temperature for the compressor 5, the compressor 5 compresses and refrigerates. At the same time, the three-way valve 6 switches to the switching section 71 to conduct, and the parallel pipeline 8 is closed, that is, if the water-cooling unit determines that the compressor 5 is suitable for operation, the compressor 5 runs, the water pump runs, and the three-way valve 6 switches to the switching section 71 to conduct.

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention.
