A scroll compressor 100 according to an embodiment of the present utility model is described below with reference to fig. 1 to 7.

As shown in fig. 1 and 2, a scroll compressor 100 according to an embodiment of the present utility model includes: a housing assembly 10, a circuit board 20, a power device 30, a motor and compression member 60.

Specifically, as shown in fig. 2, a first chamber 11 and a second chamber are arranged in the casing assembly 10 at intervals, the circuit board 20 is vertically arranged in the first chamber 11, the pins 31 of the power device 30 are electrically connected with the circuit board 20, a heat-conducting silica gel sheet 40 is arranged between the power device 30 and the inner wall of the first chamber 11, the heat-conducting silica gel sheet 40 is a flexible member, the heat-conducting silica gel sheet 40 is respectively contacted with the power device 30 and the inner wall of the first chamber 11 and conducts heat, the motor and the compression part 60 are respectively arranged in the first chamber 11 and the second chamber 12, the motor is electrically connected with the circuit board 20, and the motor is connected with the movable disc 61 of the compression part 60 through a crankshaft.

Therefore, the circuit board 20 and the power device 30 are both installed in the first chamber 11 of the housing assembly 10, so that the circuit board 20 and the power device 30 are protected through the housing assembly 10, and the power device 30 is electrically connected with the circuit board 20, so that the circuit board 20 is conveniently wired to realize power supply, power failure and control of the power device 30, and the working state of the power device 30 is conveniently controlled.

Further, the heat-conducting silicone sheet 40 is a flexible member, and the heat-conducting silicone sheet 40 is in heat-conducting contact with the power device 30 and the inner wall of the first chamber 11, respectively. For example, the heat-conducting silica gel sheet 40 may be made of silica gel material, and a certain amount of heat-conducting powder may be added into the silica gel material to make the heat-conducting silica gel sheet 40 have heat-conducting effect, wherein the heat-conducting silica gel sheet 40 may be independently processed and molded.

Thus, the thermally conductive silicone sheet 40 is a separate solid structure. In this way, the heat-conducting silicone sheet 40 can be directly installed in the first chamber 11 during actual installation, and the heat-conducting silicone sheet 40 is a flexible member, so that rigid collision with other structures during installation can be avoided.

In actual installation, the heat-conducting silica gel sheet 40 can be installed in the first chamber 11 along the installation direction of the power device 30, so that the installation difficulty of the heat-conducting silica gel sheet 40 is reduced, the installation time is saved, and the installation efficiency is improved.

Meanwhile, the heat conduction silica gel sheet 40 is convenient for playing a role of heat conduction between the power device 30 and the inner wall of the first chamber 11, so that when the power device 30 works to generate heat, the heat of the power device 30 can be transferred to the inner wall of the first chamber 11 through the heat conduction silica gel sheet 40, namely, the heat conduction silica gel sheet 40 can conduct heat transfer between the power device 30 and the inner wall of the first chamber 11.

It should be noted that, the inner wall of the first chamber 11 is a part of the housing assembly 10, so after the heat conducting silica gel sheet 40 transfers the heat of the power device 30 to the inner wall of the first chamber 11, the heat can be emitted from the housing assembly 10 to the external space, thereby realizing heat dissipation of the power device 30, and thus, the heat conducting silica gel sheet 40 can timely transfer the heat generated by the power device 30 during operation to the outside of the housing assembly 10, so as to ensure that the power device 30 can operate for a long time and with high reliability at the use environment temperature.

On the other hand, the heat-conducting silicone sheet 40 is located between the power device 30 and the inner wall of the first chamber 11, so that the heat-conducting silicone sheet 40 can fill the gap between the power device 30 and the inner wall of the first chamber 11, thereby playing a role of supporting the power device 30, so as to avoid abnormal sound generated by collision between the power device 30 and the inner wall of the first chamber 11 due to shaking.

The motor and the compression part 60 are respectively arranged in the first chamber 11 and the second chamber 12, the first chamber 11 and the second chamber 12 are arranged at intervals for reasonable layout, the compression part 60 comprises a movable disc 61 and a static disc 62, the movable disc 61 and the static disc 62 are matched to define a compression cavity, and the movable disc 61 and the static disc 62 are matched to realize the compression effect of the scroll compressor 100.

In the prior art, a liquid organic silica gel is adopted between a high-power device and a heat dissipation part of an electric scroll compressor to realize heat transfer, and the liquid organic silica gel is filled between the high-power device and the heat dissipation part and solidified by means of wet air or temperature. However, the liquid silicone gel having fluidity should be limited in installation state when in use, so that the consistency is poor after curing, and the curing process requires time, resulting in low installation efficiency of the liquid silicone gel.

In the present utility model, the heat-conducting silica gel sheet 40 is a solid structure formed independently, and can be directly installed in the first chamber 11 to realize heat transfer between the power device 30 and the housing assembly 10, and the installation state is not required to be limited when in use, so as to reduce the installation difficulty of the heat-conducting silica gel sheet 40, and the heat-conducting silica gel sheet 40 can be directly used after installation, thereby being convenient for saving the time required by the solidification process of the liquid organic silica gel in the prior art, being convenient for reducing the production cost, and being beneficial to improving the installation efficiency of the heat-conducting silica gel sheet 40.

According to the scroll compressor 100 of the embodiment of the utility model, the heat-conducting silica gel sheet 40 can be directly installed in the scroll compressor 100, so that the installation efficiency of the heat-conducting silica gel sheet 40 is improved, and the heat-conducting silica gel sheet 40 is respectively in contact with the power device 30 and the inner wall of the first chamber 11 and conducts heat, so that heat generated when the power device 30 works is transmitted to the shell assembly 10 in time, heat dissipation of the power device 30 is realized, and the working reliability and the service life of the power device 30 are improved.

In some embodiments, the thermally conductive silicone sheet 40 has a hardness of 40±20 degrees.

"hardness" is a physical measure of the degree of deformation under pressure or puncture resistance of a substance. Hardness can be relative hardness and absolute hardness. Absolute hardness is generally used in the scientific community and rarely used in production practice. We generally use a hardness system as the relative hardness, and several labeling methods are commonly used: shore also called Shore, english SHORE, rockwell and Brucella. Shore is generally used on rubber-like materials.

The hardness of the heat conductive silicon sheet 40 in the present utility model is shore hardness, and the test method is as follows: the Shore hardness tester is used to insert the measured material, the pointer on the dial is connected with a puncture needle through a spring, the needle is used to puncture the surface of the measured object, and the numerical value displayed on the dial is the hardness value.

If the hardness of the heat conducting silica gel sheet 40 is 45 degrees, or if the hardness of the heat conducting silica gel sheet 40 is 50 degrees, or if the hardness of the heat conducting silica gel sheet 40 is 55.6 degrees, that is, when the hardness of the heat conducting silica gel sheet 40 meets the above range, the heat conducting silica gel sheet 40 has a certain hardness, and can play a role in supporting the power device 30 in the first chamber 11, so as to enhance the structural stability of the power device 30.

Meanwhile, the hardness of the heat-conducting silica gel sheet 40 is not too high, the heat-conducting silica gel sheet 40 has certain elasticity, namely the heat-conducting silica gel sheet 40 has certain compression ratio, so when the heat-conducting silica gel sheet 40 is installed between the power device 30 and the inner wall of the first chamber 11, the heat-conducting silica gel sheet 40 can be compressed to a certain extent through the inner walls of the power device 30 and the first chamber 11, so that the heat-conducting silica gel sheet 40 is in a compression state, and the heat-conducting silica gel sheet 40 can be better filled between the power device 30 and the inner wall of the first chamber 11, so that the heat-conducting silica gel sheet 40 is in full soft contact with the inner walls of the power device 30 and the first chamber 11 respectively.

Therefore, the heat conduction silica gel sheet 40 can better radiate heat of the power device 30, and meanwhile, the heat conduction silica gel sheet 40 plays a good role in damping and supporting the cantilever-mounted power device 30, so that the influence of vibration of the scroll compressor 100 on stress concentration of the power device 30 is reduced, and the reliability and the service life of the scroll compressor are ensured.

Preferably, the compression ratio of the thermally conductive silicone sheet 40 is 20% to 80%.

For example, the compression ratio of the heat-conducting silica gel sheet 40 is 30%, or the compression ratio of the heat-conducting silica gel sheet 40 is 50%, or the compression ratio of the heat-conducting silica gel sheet 40 is 65%, when the compression ratio of the heat-conducting silica gel sheet 40 is within the above value range, the failure of the heat-conducting silica gel sheet 40 due to transitional compression can be avoided, and the reliability and the service life of the heat-conducting silica gel sheet 40 can be ensured.

In some embodiments, thermally conductive silicone sheet 40 is bonded to power device 30.

Therefore, the connection stability of the heat conduction silica gel sheet 40 and the power device 30 is convenient to be enhanced, and the heat conduction silica gel sheet 40 is prevented from being separated from the power device 30.

Further, as shown in fig. 4, one side of the thermally conductive silicone sheet 40 is provided with a glue layer 41 as shown on the left side in fig. 4 to be adhered to the power device 30, and at least a portion of the thermally conductive silicone sheet 40 is configured to have an adhesive property to be adhered to the cabinet assembly 10.

From this, can bond the both sides of heat conduction silica gel piece 40 respectively to power device 30 and casing subassembly 10 to strengthen the connection stability between heat conduction silica gel piece 40 and power device 30, heat conduction silica gel piece 40 and the casing subassembly 10, avoid heat conduction silica gel piece 40 to drop between power device 30 and the casing subassembly 10, and this fixed mode is simpler, does benefit to the fixed degree of difficulty that reduces heat conduction silica gel piece 40.

In some embodiments, the thermal conductivity of the thermally conductive silicone sheet 40 is greater than or equal to 1.0W/mK.

For example, the thermal conductivity of the thermal silicon sheet 40 is 1.0W/mK, or the thermal conductivity of the thermal silicon sheet 40 is 3.0W/mK, or the thermal conductivity of the thermal silicon sheet 40 is 3.5W/mK, and when the thermal conductivity of the thermal silicon sheet 40 meets the above value range, the thermal silicon sheet 40 has an optimal thermal effect, so that when the thermal silicon sheet 40 transfers the heat generated when the power device 30 works to the housing assembly 10, the thermal efficiency of the thermal silicon sheet 40 can be improved, and the heat dissipation efficiency of the power device 30 can be improved, which is beneficial to improving the working reliability and service life of the power device 30.

In some embodiments, the breakdown voltage of the thermally conductive silicone sheet 40 is greater than or equal to 10kV/mm.

For example, the breakdown voltage of the heat conducting silica gel sheet 40 is 10kV/mm, or the breakdown voltage of the heat conducting silica gel sheet 40 is 11kV/mm, or the breakdown voltage of the heat conducting silica gel sheet 40 is 12.2kV/mm, when the breakdown voltage of the heat conducting silica gel sheet 40 is within the above value range, the problem that the heat conducting silica gel sheet 40 conducts electricity can be avoided, and when the power device 30 has a certain electric leakage problem, the voltage of the power device 30 cannot break through the heat conducting silica gel sheet 40, so that the shell component 10 can be prevented from being electrified due to the electric leakage of the power device 30, and the use environment of the scroll compressor 100 is ensured to be safer.

In some embodiments, the thermally conductive silicone sheet 40 has a low molecular siloxane content of < 0.01%.

The low-molecular siloxane has certain volatility, so that the volatilization of the low-molecular siloxane easily causes the problems of failure of electrical connection of structures around the low-molecular siloxane, reduction of electrical insulation performance and the like.

In the present utility model, when the scroll compressor 100 is used, the first chamber 11 is a closed space, and the circuit board 20, the power device 30, etc. are installed in the first chamber 11, so that when the power device 30 is powered on, the heat conducting silicone sheet 40 will transfer the heat of the power device 30 to the housing assembly 10, at this time, the high temperature of the heat conducting silicone sheet 40 will cause the low molecular silicone to volatilize into the first chamber 11, and the volatilization of the low molecular silicone will easily cause the electrical connection failure between the circuit board 20 and the power device 30 and the electrical insulation performance of the heat conducting silicone sheet 40 to decrease.

Therefore, in order to ensure that the use environments of the circuit board 20, the power device 30 and the thermal conductive silicone sheet 40 are safer, the low molecular silicone content of the thermal conductive silicone sheet 40 needs to be controlled at a lower level, for example, the low molecular silicone content of the thermal conductive silicone sheet 40 is 0.009%, or the low molecular silicone content of the thermal conductive silicone sheet 40 is 0.008%, or the low molecular silicone content of the thermal conductive silicone sheet 40 is 0.007%, when the low molecular silicone content of the thermal conductive silicone sheet 40 satisfies the above value range, the volatilization of the low molecular silicone can be reduced when the thermal conductive silicone sheet 40 transfers the heat of the power device 30 to the housing assembly 10, so that the volatilization of the low molecular silicone is prevented from affecting the circuit board 20, the power device 30 and the thermal conductive silicone sheet 40, and the use environments of the circuit board 20, the power device 30 and the thermal conductive silicone sheet 40 are safer, which is beneficial to improving the working stability and the service life of the scroll compressor 100.

In some embodiments, the thermally conductive silicone sheet 40 is used at a temperature of-50 ℃ to 200 ℃.

If the use temperature of the thermal silicon sheet 40 is-30 ℃, or the use temperature of the thermal silicon sheet 40 is 20 ℃, or the use temperature of the thermal silicon sheet 40 is 120 ℃, when the use temperature of the thermal silicon sheet 40 meets the above value range, the thermal silicon sheet 40 can be prevented from losing efficacy due to overhigh temperature or overlow temperature, and the thermal silicon sheet 40 can be ensured to stably transfer heat between the power device 30 and the housing assembly 10, so that the service life of the thermal silicon sheet 40 is ensured.

In some embodiments, as shown in fig. 2 and 3, a first side of the power device 30 is soldered to the circuit board 20 by pins 31, as shown on the left side in fig. 3, and a side wall of the power device 30 facing away from the first side is provided with a thermally conductive silicon sheet 40, as shown on the right side in fig. 3.

Therefore, the circuit board 20 and the heat-conducting silica gel sheet 40 are respectively arranged on two opposite sides of the power device 30, so that vibration of the power device 30 can be damped by the heat-conducting silica gel sheet 40 in the operation process of the scroll compressor 100, concentrated stress at the pin 31 of the power device 30 can be relieved, and long-term reliability of the scroll compressor 100 is ensured.

In some embodiments, as shown in fig. 2 and 3, scroll compressor 100 also includes a fixed connection 50.

As shown in fig. 2 and 3, the fixing connector 50 is fixed to the cabinet assembly 10 through the circuit board 20 to fixedly mount the circuit board 20.

Therefore, the circuit board 20 is fixedly mounted on the housing assembly 10 by the fixing connector 50, so that the structural stability of the circuit board 20 is enhanced, and the circuit board 20 is prevented from shaking.

For example, the fixing connector 50 may be a bolt, and the bolt is inserted through the circuit board 20 to be fixed to the chassis assembly 10, and an end of the bolt away from the chassis assembly 10 abuts against the circuit board 20, so that the circuit board 20 may be fixedly mounted on the chassis assembly 10, thereby facilitating the enhancement of the structural stability of the circuit board 20.

Of course, the fixing connection member 50 may have other structures, for example, the fixing connection member 50 may be a clamping post, and the clamping post penetrates the circuit board 20 and is connected to the chassis assembly 10 in a clamping manner to fix the circuit board 20, that is, the fixing connection member 50 may be any structure capable of fixing the circuit board 20 to the chassis assembly 10.

It should be noted that, the connection manner between the fixing connector 50 and the housing assembly 10 may be: the bolt connection, the clamping connection, the inserting connection, the magnetic attraction fit and the like are not limited herein.

In some embodiments, as shown in fig. 2, the cabinet assembly 10 includes a low pressure housing 101, a high pressure housing 102, and a bracket 103, with the bracket 130 sandwiched between the low pressure housing 101 and the high pressure housing 102.

Wherein, as shown in fig. 2, the motor and the compression part 60 are arranged at two sides of the bracket 103, the bracket 103 is provided with a containing cavity 13 for containing the supporting bearing 15, the containing cavity 13 is communicated with the oil return channel 14 in the shell assembly 10, and the crankshaft is respectively connected with the movable disk 61 through the bracket 103 and the supporting bearing 15.

The scroll compressor 100 further includes a thrust member 70, the thrust member 70 being provided in the accommodating chamber 13 and being located on a side of the support bearing 15 facing away from the compression member 60, the thrust member 70 including a thrust portion 71 and a sealing portion 72, the thrust portion 71 being respectively abutted against the support bearing 15 and the bracket 103, the thrust portion 71 being provided with the sealing portion 72 protruding therefrom and being in contact with an inner wall of the accommodating chamber 13.

Thereby, the tightness between the thrust component 70 and the bracket 103 can be enhanced, so that the problem of lubricating oil leakage at the assembling position of the thrust component 70 is prevented, the problem of oil shortage at the friction pair of the parts such as the support bearing 15, the movable plate 61 and the like is avoided, and the power consumption of the scroll compressor 100 and the abrasion of the friction pair are reduced.

For example, as shown in fig. 1, the scroll compressor 100 includes a housing, a bracket 103, a compression member 60, a crankshaft, a thrust member 70, and an electronic control unit.

As shown in fig. 1, the crankshaft passes through the bracket 103, the thrust member 70 and the support bearing 15 to be connected with the movable disk 61, and the thrust member 70 is located in the accommodating chamber 13 and located at one axial side of the support bearing 15 and sandwiched between the bracket 103 and the bracket 103, wherein during operation of the scroll compressor 100, cooling oil can enter the accommodating chamber 13 through the oil passage 33 to form lubricating oil, so that the lubricating oil can be used for lubricating the support bearing 15 and the movable disk 61.

For example, during operation of scroll compressor 100, the motor drives the crankshaft to rotate moving disc 61, and moving disc 61 intermeshes with the teeth of stationary disc 62 to effect the pumping, compression and discharge of the refrigerant.

The scroll compressor 100 is provided with an air suction port and an air discharge port, the air suction port is communicated with an outlet of the system evaporator through a pipeline, and the air discharge port is communicated with an inlet of the system condenser through a pipeline. The crank shaft rotates and drives the movable disk 61 to revolve and translate under the driving action of the motor, and the compression member 60 compresses the refrigerant.

Further, the mixed fluid of the refrigerant and the refrigerating oil is sucked into the suction side area, sucked into the compression cavity through the suction channel and compressed, discharged to the static disc exhaust area through the exhaust port of the static disc 62, then enters the centrifugal oil to perform oil-gas separation, and is discharged out of the scroll compressor 100 after passing through the exhaust area of the scroll compressor 100, and continuously circulated through the system.

On the other hand, due to the centrifugal oil, the frozen oil is separated and collected in the oil storage area. After being throttled by the throttle mechanism, the frozen oil is supplied to the bracket oil return channel, and then enters the main bearing chamber area to form lubricating oil, and the lubricating oil is used for lubricating one side of the movable disc 61, which is away from the static disc 62, and the anti-rotation mechanism.

The main bearing housing region is an oil storage space formed by thrust members 70 provided at the mating portions of the crank shaft and the bracket 103, and is provided with passages communicating with the intake side, while the main bearing housing region is bonded to the wear plate by the movable plate 61 and the bracket 103. Therefore, the refrigerating oil circulation is required to enter the main bearing chamber region through the throttle mechanism, and the friction pair formed by the parts such as the support bearing 15 and the movable disk 61 is effectively lubricated and cooled, and impurities are prevented from remaining in the bearing friction track.

In the related art, due to poor sealing performance between the thrust member 70 and the bracket 103, lubricating oil leaks from the assembling position of the thrust member 70, so that the friction pair of the parts such as the support bearing 15 and the movable disk 61 is starved, poor lubrication and the like are caused, and further, the problems of increased power consumption, abrasion of the friction pair and the like of the scroll compressor 100 are caused.

Note that, the sealing portion 72 and the thrust portion 71 may be integrally formed, or the sealing portion 72 and the thrust portion 71 may be separately formed, which is not limited herein.

In the present utility model, however, by providing the seal portion 72 protruding therefrom on the thrust portion 71, the sealability between the thrust portion 71 and the inner wall of the accommodation chamber 13 can be enhanced, thereby preventing the problem of leakage of the lubricating oil at the fitting portion of the thrust member 70.

In some embodiments, as shown in fig. 5, a portion of the outer peripheral wall of the thrust portion 71 projects outwardly to define a sealing portion 72.

Thereby, the thrust portion 71 and the sealing portion 72 can be in an integrally formed structure, that is, the thrust portion 71 and the sealing portion 72 can be integrally formed, so that the sealing portion 72 does not need to be arranged on the thrust portion 71 independently, the assembly difficulty is reduced, and the production cost is reduced.

For example, as shown in fig. 5, the outer diameter of the intermediate portion of the outer peripheral wall of the thrust portion 71 is larger than the outer diameter of the other portions of the outer peripheral wall of the thrust portion 71, i.e., the intermediate portion of the outer peripheral wall of the thrust portion 71 protrudes outward from the thrust portion 71 in the radial direction of the thrust portion 71 to form a seal portion 72.

Therefore, the thrust portion 71 and the sealing portion 72 can be of an integrally formed structure, so that the assembly difficulty is reduced, and the production cost is reduced.

In some embodiments, as shown in fig. 6, the sealing portion 72 and the thrust portion 71 are separate pieces.

Thereby, it is convenient to separately provide the seal portion 72 on the thrust portion 71, and when abrasion or damage occurs to the seal portion 72, only the seal portion 72 can be replaced, so that maintenance cost can be reduced.

Further, as shown in fig. 6, the outer peripheral wall of the thrust member 70 is provided with an annular receiving groove 711, and the seal portion 72 is provided in the receiving groove 711 and protrudes from the thrust portion 71 to be in contact with the inner wall of the receiving chamber 13.

Thereby, by providing the accommodating groove 711 so as to fix the sealing portion 72 in the accommodating groove 711, the connection stability of the sealing portion 72 and the thrust member 70 is enhanced, and the sealing portion 72 protrudes from the thrust member 70 so that the sealing portion 72 can be in contact with the inner wall of the accommodating chamber 13, thereby enhancing the sealing effect between the thrust member 70 and the inner wall of the accommodating chamber 13.

For example, the sealing portion 72 may be configured as an annular sealing ring, which is sleeved on the thrust member 70 and is located in the annular receiving groove 711, so that the contact area between the sealing portion 72 and the thrust member 70 can be increased to enhance the connection stability between the sealing portion 72 and the thrust member 70, and the sealing portion 72 can be limited by the receiving groove 711 to prevent the sealing portion 72 from being separated from the thrust member 70.

Meanwhile, in the assembling process of the scroll compressor 100, the sealing portion 72 may be first installed in the accommodating groove 711, and then assembled together with the bracket 103, so that the assembling process is simplified, and the assembling difficulty is reduced.

In some embodiments, as shown in fig. 5, at least one end surface of the thrust portion 71 is provided with an oil containing groove 73 in the axial direction of the crankshaft.

Thus, when oil is present on the end surface of the thrust member 70 in the axial direction of the crankshaft, the oil is temporarily stored in the oil tank 73, and when oil is present in the oil tank 73, the oil in the oil tank 73 can lubricate between the thrust member 70 and the support bearing, thereby reducing wear of the support bearing 15 and the thrust member 70.

Further, as shown in fig. 5, the oil receiving groove 73 extends to the outer peripheral wall of the thrust portion 71.

Thus, when the oil is provided between the outer peripheral wall of the bracket 103 and the inner peripheral wall of the housing chamber 13, the oil can flow into the oil receiving groove 73, and the oil in the oil receiving groove 73 can lubricate between the thrust bearing 70 and the support bearing, thereby reducing wear of the support bearing 15 and the thrust bearing 70.

In some embodiments, as shown in fig. 2, the power device 30 is located above the first chamber 11.

Therefore, the difficulty in assembling and disassembling the power device 30 is reduced, and interference between the power device 30 and the compression part 60 is avoided.

For example, as shown in fig. 2, the power device 30 is located radially above the first chamber 11, so that the power device 30 is installed in a cantilever manner, on one hand, the size of the scroll compressor 100 in the axial direction can be reduced, and on the other hand, the installation difficulty of the power assembly installed in a cantilever manner is low, which is beneficial to improving the production efficiency.
