Among them, the PTC heater 140 has advantages of small thermal resistance, high heat exchange efficiency, and the like.

For example, the PTC heater 140 includes a wick 146 and an electrode plate 147, the wick 146 extends into the liquid containing chamber 180 to heat the liquid in the liquid containing chamber 180, the wick 146 may be electrically connected to the control portion of the compressor assembly 100 through the electrode plate 147, and the wick 146 may be made of a metallic aluminum material. The liquid containing chamber 180 may be provided with an opening 183 for mounting and dismounting the PTC heater 140, and the compressor assembly 100 may include a first cover plate 191, and the first cover plate 191 may be mounted to the end cap part 112 and cover the opening 183, so that the probability of damage to the PTC heater 140 is reduced, the safety of the PTC heater 140 is improved, and the dissipation of energy is reduced.

It will be understood by those skilled in the art that the casing 110 is provided with a suction port (not shown) for sucking the refrigerant into the compressing part and an exhaust port (not shown) for discharging the refrigerant compressed by the compressing part. The temperature of the refrigerant in the suction port is low, for example, below 10 ℃, the temperature of the exhaust port is high, for example, over 80 ℃, and the exhaust port can be close to the liquid containing cavity 180.

According to the compressor assembly 100 of the embodiment of the invention, the casing 110 is arranged to include the body part 111 and the end cover part 112, the body part 111 and the end cover part 112 are matched to define the placing cavity 113, the end cover part 112 is provided with the liquid containing cavity 180 arranged at an interval with the placing cavity 113, the compression part is arranged in the placing cavity 113, the compression part can exchange heat with liquid in the liquid containing cavity 180 after doing work in summer to reduce the temperature of the compression part, and the compression part can continuously exchange heat with the liquid because the liquid in the liquid containing cavity 180 continuously flows, so that the efficiency of cooling the compression part is improved, the pressure difference inside the compression part can be rapidly reduced, and the probability of stopping the compressor is reduced.

In addition, after the compressor assembly 100 is stopped, the compressor assembly 100 requires less power to start the compressor assembly 100 due to the smaller pressure difference inside the compression part, so that the compressor assembly 100 can be started quickly. And because the pressure difference inside the compression part is smaller, the overload risk of a power device in the compressor assembly 100 is lower, and the power device does not need excessive allowance, so that the service life and the production cost of the compressor assembly 100 are considered, and the overall power consumption of the compressor assembly 100 can be reduced.

In addition, as the PTC heater 140 is arranged in the liquid containing cavity 180 to heat the liquid in the liquid containing cavity 180, the PTC heater 140 can be started in advance before the compression component is started in winter, the liquid in the liquid containing cavity 180 is heated by the PTC heater 140, the temperature of the compression component can be heated to a proper starting condition by the liquid, and the compression component can be normally started even when the ambient temperature is low.

Therefore, the compressor assembly 100 according to the embodiment of the invention can be started normally and quickly under high and low temperature working conditions, and has the advantages of low cost, low energy consumption, long service life and the like.

According to some embodiments of the present invention, as shown in fig. 7, the PTC heater 140 includes a first group of ribs 141 and a second group of ribs 142, the first group of ribs 141 and the second group of ribs 142 are alternately arranged, the first group of ribs 141 and the second group of ribs 142 may be parallel to each other, at least one liquid running gap 143 is defined between the adjacent first group of ribs 141 and the second group of ribs 142, a first liquid running passage 144 communicating with the liquid running gap 143 is defined between the first group of ribs 141 and an inner wall of the liquid containing chamber 180, and a second liquid running passage 145 communicating with the liquid running gap 143 is defined between the second group of ribs 142 and the inner wall of the liquid containing chamber 180.

Specifically, the first fluid running channel 144 and the second fluid running channel 145 are located on opposite sides of the PTC heater 140.

For example, the first and

second ribs

141 and 142 may be formed on the core 146 and extend into the liquid containing chamber 180, the first and

second ribs

141 and 142 are provided with connecting pieces (not shown) protruding toward the electrode plate 147, the electrode plate 147 is provided with connecting holes, and the connecting pieces and the connecting holes are matched, so that the first and

second ribs

141 and 142 are electrically connected to the electrode plate 147, respectively, and the relative position between the core 146 and the electrode plate 147 is fixed. And the PTC heater 140 can heat the liquid in the liquid containing tank by the first and second sets of

fins

141 and 142.

In addition, the liquid containing chamber 180 may include a first inner wall and a second inner wall opposite to the first inner wall, the first set of ribs 141 may contact with the first inner wall and form a first liquid flowing channel 144 at a distance from the second inner wall, the second set of ribs 142 may contact with the second inner wall and form a second liquid flowing channel 145 at a distance from the first inner wall, the first set of ribs 141 and the second set of ribs 142 are staggered at intervals along the extending direction of the first inner wall (i.e., the extending direction of the second inner wall), and the liquid in the liquid containing chamber 180 flows in the plurality of liquid flowing gaps 143, the first liquid flowing channel 144 and the second liquid flowing channel 145, thereby forming an S-shaped flow path. Thus, the liquid can be more sufficiently contacted with the first and second sets of

ribs

141 and 142, and the heat exchange between the liquid and the PTC heater 140 is more sufficient, thereby improving the heating efficiency of the liquid by the PTC heater 140.

According to some embodiments of the present invention, as shown in fig. 2-4 and fig. 6, the liquid containing cavity 180 has a liquid inlet 181 and a liquid outlet 182, one of the liquid inlet 181 and the liquid outlet 182 is communicated with the first liquid removing channel 144 and the other is communicated with the second liquid removing channel 145. Wherein the temperature of the liquid entering the liquid holding chamber 180 from the liquid inlet 181 can be lower than 60 ℃. The liquid inlet 181 and the liquid outlet 182 are arranged to facilitate the liquid in and out of the liquid containing cavity 180, and can also guide the liquid into the first liquid outlet channel 144 and the second liquid outlet channel 145.

Further, a plurality of stop ribs (not shown) are disposed in the liquid containing chamber 180, and the first set of ribs 141 and the second set of ribs 142 stop against the stop ribs respectively. Wherein, the stop rib is configured on the bottom wall of the liquid containing cavity 180. Therefore, the contact between the first group of fins 141 and the second group of fins 142 and the bottom wall of the liquid containing cavity 180 is reduced to be tighter, the liquid can better flow along the extension directions of the plurality of liquid walking gaps 143, the first liquid walking channel 144 and the second liquid walking channel 145, the liquid is prevented from directly flowing among the plurality of liquid walking gaps 143 without passing through the first liquid walking channel 144 and the second liquid walking channel 145, the liquid can be further ensured to be more fully contacted with the first group of fins 141 and the second group of fins 142, the heat exchange between the liquid and the PTC heater 140 is further more fully realized, and the heating efficiency of the PTC heater 140 on the liquid is further improved.

According to some embodiments of the present invention, as shown in fig. 2 and 6, the liquid outlet 182 is located at the top of the liquid containing chamber 180, so that the concentration of bubbles at the top of the liquid containing chamber 180 can be avoided, and the dry burning of the PTC heater 140 can be prevented. In addition, the liquid inlet 181 may be located at the bottom of the liquid containing cavity 180, and since the temperature of the liquid in the liquid inlet 181 is lower than that of the liquid in the liquid outlet 182, the heat dissipation probability of the compression component may be improved.

According to some embodiments of the present invention, as shown in fig. 3 and 4, an electric control chamber 150 is further disposed on the housing 110, an electric control device 151 is disposed in the electric control chamber 150, and the electric control device 151 is electrically connected to the compression member and the PTC heater 140 to control the operation states of the compression member and the PTC heater 140.

For example, the housing 110 may include a second cover plate 192 for covering the electrical control chamber 150, and the second cover plate 192 and the housing 110 may be coupled by a threaded fastener (e.g., a bolt). The electric control chamber 150 may be close to the air suction port of the compression component, and since the electric control device 151 may be provided with various electric elements (e.g., power elements), the electric control device 151 may generate a higher temperature during operation, and the electric control device 151 may be cooled by a low-temperature refrigerant of the air suction port. The operation of the compression member and the PTC heater 140 can be better controlled by the electric control device 151.

Further, as shown in fig. 5, the electric control device 151 includes an electric control board 152, a first IGBT module 153, and a second IGBT module 154.

The first IGBT module 153 and the compression component may be welded by resistance welding, and the electronic control board 152 may be connected to an external high-voltage power source through the high-voltage connector 172, so that the electronic control device 151 may supply power to a high-voltage element (e.g., the PTC heater 140) in the compressor assembly 100, and the electronic control board 152 may communicate with the outside through the low-voltage connector 173 and supply power to a low-voltage element in the compressor assembly 100. The compression part and the PTC heater 140 can be simultaneously controlled by the electric control board 152, and there is no need to separately provide an electric control board for each of the compression part and the PTC heater 140, thereby improving space utilization, reducing the weight of the compressor assembly 100, and reducing the energy consumption of the compressor assembly 100.

According to some embodiments of the present invention, as shown in fig. 3 to 5, compressor assembly 100 further includes an elastic member 161, and elastic member 161 is fixed on casing 110 and abuts against electric control device 151 to position electric control device 151 in electric control chamber 150. The elastic member 161 may be a rigid elastic sheet.

For example, a portion of the elastic member 161 may be stacked with the electric control device 151, in other words, the electric control device 151 may be located between the elastic member 161 and the casing 110, and the rest of the elastic member 161 is mounted to the casing 110 by a threaded fastener (e.g., a bolt). The elastic member 161 is used for positioning the relative position between the electric control device 151 and the casing 110, and the elastic member 161 has the elastic deformation capability, so that the electric control device 151 can have different sizes, the elastic member 161 can deform along with the shape of the electric control device 151, and the compressor assembly 100 can select different electric control devices 151 according to actual use requirements, thereby improving the universality of the compressor assembly 100. Moreover, the elastic restoring force of the deformed elastic element 161 can make the electric control device 151 and the casing 110 more tightly attached to each other, so that the overall structure of the compressor assembly 100 is more stable.

According to some embodiments of the present invention, an insulating member (not shown) is disposed between the electric control device 151 and the housing 110. The insulating piece can be an insulating ceramic piece or an insulating gasket. Through the arrangement of the insulating member, it can be ensured that the electric control device 151 is insulated from the housing 110, that is, there is no electric conduction between the electric control device 151 and the housing 110, so that the reliability of the electric control device 151 is ensured, and the electric control device 151 is prevented from short-circuiting and the like.

Further, as shown in fig. 3 and 5, a heat conducting member 163 is disposed between the insulating member and the casing 110. The heat-conducting member 163 may be a heat-conducting silicone grease applied to the housing 110, the insulating member is attached to the housing 110 to which the heat-conducting silicone grease is applied, and the electric control device 151 is further mounted on a side of the insulating member facing away from the housing 110. Since the electric control device 151 is provided with power elements (e.g., the first IGBT module 153 and the second IGBT module 154), and since the heat generated by the power elements during operation is relatively high, the overall heat dissipation efficiency of the electric control device 151 can be increased by providing the heat conduction member 163, and the work efficiency and the service life of the electric control device 151 can be ensured. In some embodiments of the present invention, the electrical control device 151 may also be provided with a thermal conductive member 163, for example, by applying thermal conductive silicone grease to the surfaces of the first IGBT module 153 and the second IGBT module 154, so as to further improve the heat dissipation efficiency of the electrical control device 151 as a whole.

According to some embodiments of the present invention, as shown in fig. 1 to 3, the housing 110 is provided with a first plug 115 electrically connected to the electric control device 151, the compressor assembly 100 further includes a connection harness 170, one end of the connection harness 170 is electrically connected to the PTC heater 140, the other end of the connection harness 170 is provided with a second plug 171, and the second plug 171 is in plug-in fit with the first plug 115 to electrically connect the PTC heater 140 to the electric control device 151. Therefore, the electric control device 151 can supply power to the PTC heater 140, the PTC heater 140 generates heat to heat the liquid in the liquid containing cavity 180, and the electric connection is reliable and the plugging and unplugging are convenient.

According to some embodiments of the present invention, as shown in fig. 1, the body portion 111 includes a first chamber housing 116 and a second chamber housing 117, the first chamber housing 116 is fixed on the second chamber housing 117, the first chamber housing 116 defines the electric control chamber 150 therein, and the second chamber housing 117 and the end cover portion 112 cooperate to define the placing chamber 113.

For example, the first chamber housing 116 and the second chamber housing 117 may be connected by threaded fasteners (e.g., bolts), with the second chamber housing 117 being located between the first chamber housing 116 and the end cap portion 112. The first and

second IGBT modules

153 and 154 may be placed at the bottom of the first chamber housing 116, and the compression member may be mounted to the second chamber housing 117 by a threaded fastener.

By dividing the main body 111 into the first cavity shell 116 and the second cavity shell 117, the main body 111 is easily manufactured, the electric control device 151 and the compression component are easily repaired and replaced, and the service life and safety of the compressor assembly 100 are improved.

The electric control device 151 can be connected with three plugs of the motor through the three-phase connecting column 122, and the three-phase connecting column 122 can be connected with the electric control device 151 through a wave soldering welding mode.

Thus, the compression unit can compress and drive the refrigerant, so that the air conditioner with the compressor assembly 100 can perform normal functions, such as a cooling function or a heating function.
