[0016] The utility model will be further explained in detail in combination with the drawings and examples. It can be understood that the specific examples described herein are only used to explain the utility model, and not limited to the utility model. In addition, it should be noted that, in order to facilitate the description, only the part related to the utility model is shown in the drawing, not all structures.

[0017] In the description of the utility model, unless another definite provision and limitation, the term "link", "connect", "fix" should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or be integrated;Can be mechanical connection, also can be electrical connection;Can be directly connected, also can be indirectly connected through the intermediate medium, can be two elements inside the communication or two element's mutual action relation.For the ordinary skill in the art, the above-mentioned term can be understood in the utility model according to the specific meaning of the specific situation.

[0018] In the utility model, unless another definite provision and limitation, the first feature is "on" or "under" the second feature can include the first and second features direct contact, also can include the first and second features are not direct contact but contact through the additional feature between them.Moreover, the first feature is "on", "above" and "on" the second feature includes the first feature is directly above and obliquely above the second feature, or just indicates that the horizontal height of the first feature is higher than the second feature.The first feature is "under", "below" and "under" the second feature includes the first feature is directly below and obliquely below the second feature, or just indicates that the horizontal height of the first feature is less than the second feature.

[0019] In the description of the embodiment, the terms "on", "under", "right", etc. Orientation or positional relationship is based on the orientation or positional relationship shown in the drawing, only for the convenience of description and simplification operation, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, so it cannot be understood as a limitation on the utility model.In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0020] At present, under low-temperature environment, the refrigerant will be frozen, and the refrigerant in low-temperature state enters the compressor, and the compressor cannot obtain heat from the refrigerant, so the compressor cannot be started normally, and further cannot provide heat for the battery and the passenger cabin.

[0021] In order to solve the above problems, as Figs. 1-2 The utility model provides a self-heating compressor, including casing 1, the scroll disc is installed in casing 1, the side wall of casing 1 is equipped with liquid inlet, the inner wall of casing 1 is pasted with electric heating assembly, refrigerant enters the scroll disc along liquid inlet, electric heating assembly is electrically connected with automobile power supply, and electric heating assembly can release heat after being electrified.

[0022] After the car starts, if the temperature sensor on the car detects that the ambient temperature is too low, it will heat the electric heating components, which in turn heats the refrigerant entering the compressor. This raises the temperature of the refrigerant, allowing the self-heating compressor to operate normally. The compressor can then extract heat from the refrigerant and transfer it to the battery and air conditioning components through the thermal management system. This not only heats the passenger compartment but also raises the battery temperature, maximizing battery discharge efficiency and extending the range of new energy vehicles.

[0023] The housing 1 of this utility model is cylindrical and includes an arc-shaped surface. The electric heating component includes a first heating wire 2, which is laid on the arc-shaped surface and projected perpendicularly to the axis of the housing 1. The angle between the first heating wire 2 and the axis of the housing 1 is 45°.

[0024] By installing a first heating wire 2 inside the housing 1, the temperature inside the housing 1 is increased, which in turn increases the temperature of the low-temperature refrigerant entering the housing 1. After the refrigerant is heated, the self-heating compressor can operate normally. The first heating wire 2 of this utility model is installed at an angle and at equal intervals on the arc-shaped surface. Multiple sets of first heating wires 2 are installed on the arc-shaped inner wall inside the housing 1. The first heating wires 2 are parallel to each other and installed inside the housing 1, which makes the heating speed inside the housing 1 faster, so that the refrigerant can quickly reach the temperature required for the compressor to operate normally.

[0025] The electric heating assembly of this invention includes a second heating wire 3, which is also inclinedly laid on the arc-shaped surface, perpendicular to the axis projection of the housing 1, and perpendicular to the first heating wire 2. By setting the second heating wire 3 in a crisscross pattern with the first heating wire 2, the density of the electric heating assembly inside the housing 1 is increased, enabling the electric heating assembly to quickly reach the target temperature. The second heating wires 3 are evenly spaced on the arc-shaped surface, making the heating area inside the housing 1 more comprehensive, thereby improving heating efficiency.

[0026] The first heating wire 2 and the second heating wire 3 are fixed to the inner wall of the housing 1 in a manner similar to a printed circuit, which utilizes the space between the inner wall of the housing 1 and the internal components of the housing 1, thereby improving the space utilization efficiency of the self-heating compressor. At the same time, since the angle between the first heating wire 2 and the second heating wire 3 and the housing 1 is 45°, the first heating wire 2 and the second heating wire 3 bend less during installation, which can extend the service life of the first heating wire 2 and the second heating wire 3.

[0027] The housing 1 has end caps at both ends. First heating wires 2 and second heating wires 3 are installed at equal intervals on the end caps. The first heating wires 2 and the second heating wires 3 are perpendicular to each other. The installation of the first heating wires 2 and the second heating wires 3 on the end caps makes the heating range of the electric heating component in the self-heating compressor more comprehensive, and the refrigerant can receive circumferential heating without dead angles in the housing 1.

[0028] The thermal management system of this invention includes a self-heating compressor, an air conditioning unit, and a battery unit. The outlet of the self-heating compressor is connected to the heating pipe of the air conditioning unit, and the self-heating compressor is also connected to the heating pipe of the battery unit. Through the self-heating compressor of this invention, heat energy can be simultaneously provided to both the battery unit and the air conditioning unit.
