The structure of the compressor provided by the embodiment of the application is suitable for an integrated compressor, and the compressor realizes the integration of the frequency converter module and the compressor main body 10. Referring to fig. 1 and 2, the compressor mainly includes a compressor body 10, a hermetic shell 20, a flow guide assembly, and a heat exchanger assembly 30. The structure of the compressor body 10 is similar to that of a conventional compressor, the sealing cover 20 is hermetically connected to one side outer surface of the compressor body 10, and an installation cavity is formed between the outer surface of the compressor body 10 and the inner circumference of the sealing cover 20, and the frequency converter module, the flow guiding assembly and the heat exchanger assembly 30 are all arranged in the installation cavity and fixed relative to the compressor body 10.

The sealed housing 20 plays a role in isolating outside air from the frequency converter module, and can effectively reduce the entry of moisture in the outside air and in the air into the installation cavity, thereby reducing the condensation phenomenon. The flow guiding assembly is used for guiding and driving the air in the installation cavity to circularly flow in the installation cavity according to a set path so as to form circulating air flowing through the frequency converter module and the heat exchanger assembly 30. The heat exchanger assembly 30 is used for introducing refrigerant, utilizing the refrigerant to exchange heat with circulating wind flowing through the heat exchanger assembly 30, reducing the wind temperature of the circulating wind, improving the cooling capacity of the circulating wind to the frequency converter module, reducing the temperature of the frequency converter module, and then reducing the temperature difference between the frequency converter module and the compressor main body 10 and the sealing cover 20, and simultaneously reducing the temperature difference between the air in the installation cavity and the compressor shell and the sealing cover 20, reducing the condensation phenomenon in the installation cavity, especially in the frequency converter module, reducing the risk of fire disaster caused by circuit fault probability and short circuit, and improving the running stability of the compressor.

With continued reference to fig. 1 and 2, in one embodiment provided herein, a sealed enclosure 20 is secured over the top of the compressor body 10 such that a mounting cavity is formed above the compressor body 10. In other words, the inverter module, the flow guiding assembly and the heat exchanger assembly 30 are all disposed on top of the compressor body 10. The heat exchanger assembly 30 includes a refrigerant pool, a first fin 31, a second fin 33, and a separator 32. The refrigerant pool can be formed by recessing the surface of the top shell relative to the compressor body 10, or a baffle plate can be convexly arranged above the top shell of the compressor body 10, and the baffle plate is used for enclosing the refrigerant pool for storing the refrigerant.

The refrigerant pool can be introduced and discharged to realize the circulation flow of the refrigerant, the source of the refrigerant can be a small amount of refrigerant intercepted from the outlet of the condenser of the air conditioning system, the refrigerant is conveyed into the refrigerant pool through a corresponding pipeline, meanwhile, the refrigerant pool is connected with the evaporator through a pipeline, and the refrigerant which exchanges heat with the air in the installation cavity body through the heat exchanger assembly 30 is conveyed to the evaporator, so that the circulation of the refrigerant is ensured.

The first fins 31 are arranged in the refrigerant pool and immersed in the refrigerant liquid in the refrigerant pool, and heat of the first fins 31 is taken away through convective heat exchange with the liquid refrigerant in the refrigerant pool, so that the temperature of the first fins 31 is reduced. The second fin 33 and the first fin 31 are connected in a heat conduction manner, and specifically, the two may be integrally formed or be abutted and fixed by a fixing member.

As shown in fig. 3 to 6, in the present embodiment, the first fin 31, the second fin 33 and the partition plate 32 are integrally formed, the first fin 31 and the second fin 33 are disposed in one-to-one correspondence, and the partition plate 32 is fixedly connected between the first fin 31 and the second fin 33 to divide the first fin 31 and the second fin 33 into two parts which are vertically separated.

The partition plate 32 has a heat conduction function between the first fin 31 and the second fin 33, and conducts heat of the second fin 33 to the first fin 31, and the heat of the first fin 31 and the refrigerant in the refrigerant pool is taken away by the refrigerant after heat exchange; on the other hand, the sealing effect on the refrigerant pool is achieved, and the phenomenon that the circulation refrigerant of the air conditioning system is reduced due to the fact that the refrigerant in the refrigerant pool evaporates in the installation cavity is avoided, and the operation of the air conditioning system is influenced.

The shape of the partition plate 32 is matched with that of the refrigerant pool, and the size of the partition plate 32 is slightly larger than that of the refrigerant pool, so that after the first fin 31 is inserted into the refrigerant pool and immersed in the refrigerant, the peripheral edge of the partition plate 32 can cover the refrigerant pool and is attached to the peripheral edge of the top of the refrigerant pool to realize sealing.

In this embodiment, the shape of the refrigerant pool is not limited, in order to facilitate the arrangement of the array of the first fins 31 and the insertion of the first fins 31 into the refrigerant pool, the refrigerant pool generally adopts a regular square or rectangular pool body structure, and the shape and size of the partition plate 32 correspond to the first fins 31 and the refrigerant pool.

In some embodiments, in order to reduce the temperature difference between the inverter module and the compressor housing, a heat-conducting silicone grease is further disposed between the peripheral edge of the partition plate 32 and the top peripheral edge of the refrigerant pool, and the heat-conducting silicone grease not only plays a role in connecting and sealing the partition plate 32 and the refrigerant pool, but also can conduct part of the heat conducted by the second fins 33 to the partition plate 32 to the top housing of the heat-conducting compressor body 10 via the heat-conducting silicone grease, and then to the seal housing 20, so as to reduce the temperature difference between the compressor housing and the seal housing 20 and the air in the installation cavity, and the temperature difference between the compressor housing and the seal housing 20 and the inverter module.

The first fins 31 and the second fins 33 conduct heat through the partition plates 32, heat of the second fins 33 is conducted to the first fins 31, the temperature of the second fins 33 is reduced to be lower than that of air in the installation cavity, particularly, circulating air flowing to the second fins 33 is subjected to convection heat exchange with the second fins 33 when flowing through the second fins 33, the air temperature of the circulating air is obviously reduced, the circulating air is conveniently flowed to each part of the frequency converter module, and then the electronic components of the frequency converter module are cooled, so that the temperature of the frequency converter module is obviously reduced, the consistency of the air temperature in the installation cavity is improved, and the temperature difference between the air in the installation cavity and the top shell of the compressor main body 10 and the sealing cover 20 is reduced.

Further, to enhance the convective heat transfer effect between the circulating wind and the heat exchanger assembly 30. The heat exchanger assembly 30 provided by the embodiment of the application further comprises a diversion housing 34, the diversion housing 34 is a housing-shaped structure which is inversely buckled on the periphery of the second fin 33 and provided with a cavity, and the second fin 33 is arranged in the cavity of the diversion housing 34. In the illustrated embodiment, the flow guiding housing 34 adopts a square cavity housing structure adapted to the refrigerant pool, a group of opposite side surfaces of the flow guiding housing 34 are arranged in a penetrating manner, and openings of the opposite side surfaces of the flow guiding housing 34 serve as an air inlet side and an air outlet side respectively.

The air inlet side is used for allowing circulating air to flow into the cavity and exchanging heat with the second fins 33 in the cavity, the opening at the other side opposite to the air inlet side is used as the air outlet side of the diversion housing 34, and the air outlet side is used for allowing circulating air cooled after exchanging heat with the second fins 33 in the cavity to flow out of the diversion housing 34. By means of the diversion housing 34 and the arrangement of the air inlet side and the air outlet side, circulating wind can flow along the direction from the air inlet side to the air outlet side, the wind speed of the circulating wind flowing through the surface of the second fin 33 is improved, and the heat convection efficiency between the circulating wind and the second fin 33 is enhanced.

The width direction of the second fins 33 is preferably set to be consistent with the flow direction of the circulating air in the diversion housing 34, and the second fins 33 are preferably arranged in parallel with each other, so that diversion air channels are formed among the plurality of second fins 33, and the wind resistance when the circulating air flows through the second fins 33 is reduced. Specifically, the second fins 33 are arranged in a plurality of groups in the width direction of the air guide housing 34, that is, in the left-right direction shown in fig. 5, and may be arranged in a single row or a plurality of rows in the direction of the circulating air, and the first fins 31 and the second fins 33 are arranged in one-to-one correspondence.

In some other embodiments, the second fins 33 are arranged in a plurality of rows, and the second fins 33 in different rows may also be arranged in a staggered manner, which is not particularly limited in this application.

The arrangement of the first fins 31 refers to the second fins 33, the first fins 31 are arranged in a plurality of rows along the flowing direction of the liquid refrigerant in the refrigerant pool, each row is provided with a plurality of first fins 31, the width direction of each fin is preferably parallel to the flowing direction of the liquid refrigerant in the refrigerant pool, so that the flow resistance of the refrigerant flowing through the first fins 31 can be reduced, the flowing speed of the refrigerant in the refrigerant pool is increased, and the convection heat exchange efficiency of the first fins 31 and the refrigerant is enhanced.

It can be appreciated that the heat exchanger assembly 30 may be a shell-and-tube heat exchanger, etc. in which the refrigerant pool is matched with the first fin 31, the second fin 33 and the partition plate 32. The heat exchangers with different types are selected by comprehensively considering the refrigerant flow, the heat exchange efficiency and the heat exchanger size, the circulating refrigerant flow is increased, the flow resistance of circulating air is reduced, and the convection heat exchange area of the circulating air and the second fins 33 is increased by the heat exchanger assembly 30.

Referring to fig. 1, in order to facilitate the transportation of the refrigerant into and out of the condensation tank and ensure the circulation of the liquid refrigerant, a compressor body 10 is integrally provided with a refrigerant inlet pipe 11 and a refrigerant outlet pipe 12. The joint of one end of the refrigerant inlet pipe 11 and one end of the refrigerant outlet pipe 12 extend to the outer side surface of the compressor main body 10, and the other end extends to the refrigerant pool and is communicated with the refrigerant pool. The joint of the refrigerant inlet pipe 11 extending to the outer side of the compressor body 10 is used for communicating with one side of the condenser close to the refrigerant outlet through a pipeline. The joint of the refrigerant outlet pipe 12 extending to the outer side of the compressor body 10 is used for communicating with one side of the evaporator close to the refrigerant outlet through a pipeline.

The main body sections of the refrigerant inlet pipe 11 and the refrigerant outlet pipe 12 are arranged between the top of the compressor main body 10 and the bottom of the frequency converter module, so that partial heat of the compressor main body 10 and the frequency converter module is taken away in the circulating conveying process of the refrigerant. The winding structure of the refrigerant inlet pipe 11 and the refrigerant outlet pipe 12 can be related to the arrangement of the part to be cooled, and the winding fixed position of the refrigerant outlet pipe 12 of the refrigerant inlet pipe 11 can be flexibly adjusted according to the needs when the cooling device is in specific implementation. Generally, the refrigerant inlet pipe 11 and the refrigerant outlet pipe 12 may be hidden in the top housing of the compressor body 10.

In an embodiment, the driving motor is disposed below the central area of the top casing of the compressor main body 10, and the refrigerant inlet pipe 11 and the refrigerant outlet pipe 12 are wound between the top of the driving motor and the bottom of the inverter module, so that the driving motor of the compressor main body 10 can be cooled to a certain extent while the inverter module is cooled, and the running stability of the compressor is improved.

It can be understood that the refrigerant inlet pipe 11 and the refrigerant outlet pipe 12 may be integrated not only in the top shell portion of the compressor main body 10, but also may be provided with corresponding perforations at the sealing cover 20 according to need, so that the refrigerant inlet pipe 11 and the refrigerant outlet pipe 12 enter the installation cavity through the perforations on the sealing cover 20 and are communicated with the refrigerant pool. Only when the refrigerant inlet pipe 11 and the refrigerant outlet pipe 12 are integrated between the top of the compressor body 10 and the bottom of the inverter module, there is a certain inconvenience in mounting and dismounting the hermetic shell 20, and the cooling effect of the refrigerant inlet pipe 11 and the refrigerant outlet pipe 12 cannot be fully exerted.

In order to realize cooling of the inverter module under different operation load states of the compressor, the temperature difference between the air in the installation cavity and the compressor housing and the sealing cover 20, and the temperature difference between the inverter module and the compressor housing and the sealing cover 20 are reduced to a proper range, the compressor provided by the embodiment of the application further comprises a throttling element 40 for adjusting the flow of circulating refrigerant exchanging heat with the first fin 31 in the refrigerant pool.

The flow rate of the refrigerant is regulated by means of the throttling element 40, the flow rate of the refrigerant is changed, the convection heat exchange efficiency of the refrigerant and the first fins 31 is regulated, the heat conduction speed of the second fins 33 through the partition plate 32 and the first fins 31 is affected, the control of the wind temperature of circulating wind flowing through the heat exchanger assembly 30 is further realized, the regulation of the temperature of the frequency converter module and the air temperature in the installation cavity is finally realized, and the temperature difference of the frequency converter module relative to the compressor shell and the sealing cover plate and the air in the installation cavity are stabilized in a proper range relative to the compressor shell and the sealing cover plate.

When the heat productivity of the frequency converter module is large, the flow rate of the circulating refrigerant flowing into and out of the refrigerant pool can be regulated and increased through the throttling component, the heat exchange between the refrigerant at the heat exchanger component 30 and the circulating air is enhanced, and the capacity of the frequency converter module is improved. When the heating value of the frequency converter module is low, the circulation flow flowing into and out of the refrigerant pool can be properly reduced through the throttling component.

In particular, the present embodiment preferably provides the throttling element 40 at the end of the refrigerant outlet tube 12 remote from the refrigerant pool. The beneficial effect who sets up so lies in: on one hand, the refrigerant can be conveniently throttled and then enter the evaporator to evaporate, and on the other hand, the refrigerant can be prevented from being throttled before entering the refrigerant pool, and the refrigerant generates phase change heat absorption in the refrigerant pool, so that the temperature of the frequency converter module is obviously lower than the ambient temperature to generate condensation.

In order to facilitate adjusting the flow rate of the circulating refrigerant flowing through the heat exchanger assembly 30, the compressor provided in the embodiments of the present application further includes a temperature detection module for detecting the temperature of the inverter module. Illustratively, the frequency converter module includes a rectifying module 50, an inverting module 60, and a filtering module 70, and the temperature detection module correspondingly includes a first temperature sensor disposed at the rectifying module 50 for detecting a temperature of the rectifying module 50, a second temperature sensor disposed at the inverting module 60 for detecting a temperature of the inverting module 60, and a third temperature sensor disposed at the filtering module 70 for detecting a temperature of the filtering module 70. The first temperature sensor, the second temperature sensor, the third temperature sensor, and the throttling element 40 are all connected with a controller of the compressor or the air conditioner so that the controller adjusts the flow rate of the refrigerant based on the temperature of each module of the inverter module. When the temperature of each module of the frequency converter module exceeds the respective set temperature, the controller controls the throttling element 40 to adjust and increase the flow rate of the circulating refrigerant. When the temperature of each module of the frequency converter module is lower than the respective set temperature, the controller controls the throttling element 40 to regulate and reduce the flow of the circulating refrigerant.

The adjustment of the flow rate of the refrigerant can be based on not only directly detecting the temperature value of each module of the rectifying module 50, but also detecting the temperature difference between the air inlet side and the air outlet side of the diversion housing 34, or detecting the temperature difference between the circulating refrigerant in the refrigerant inlet pipe 11 and the refrigerant outlet pipe 12. Illustratively, the air inlet side of the air guiding housing 34 is provided with a fourth temperature sensor for detecting the air inlet temperature of the circulated air, and the air outlet side of the air guiding housing 34 is provided with a fifth temperature sensor for detecting the air outlet temperature of the circulated air; the opening degree of the throttling element 40 is adjusted by comparing the temperature difference of the circulating air at the air inlet side and the air outlet side of the diversion cover 34, so that the refrigerant flow is adjusted.

When the temperature difference between the circulating air on the air inlet side and the circulating air outlet side of the diversion housing 34 is larger, the heat productivity of the frequency converter is higher, and when the temperature difference between the two is larger than the first set temperature difference, the flow of the circulating refrigerant can be regulated and increased; when the temperature difference is smaller than the second set temperature difference, the flow of the circulating refrigerant can be adjusted and reduced; when the temperature difference is larger than the second set temperature difference and smaller than the first set temperature difference, the opening of the current throttling element 40 is kept, and the flow of the circulating refrigerant is kept unchanged.

Referring to fig. 2 and 7 in combination, in some embodiments, two throttling branches are disposed in parallel at an end of the refrigerant outlet pipe 12 away from the refrigerant pool, and the throttling branches are respectively defined as a first throttling branch and a second throttling branch. The throttle element 40 includes a throttle valve 41 and a throttle hole plug 42. Wherein the throttle valve 41 is arranged in the first throttle branch, and the throttle hole plug 42 is arranged in the first throttle branch. The throttle valve 41 mainly plays roles of throttling, depressurization and circulating refrigerant flow regulation; the aperture of the throttle hole plug 42 is smaller than the pipe diameter of the first throttle branch, and the throttle hole plug 42 is kept in a normally open state, so that the phenomenon that the circulating refrigerant cannot flow out due to the failure of the throttle valve 41 is avoided.

In some embodiments, the arrangement of the inverter module may refer to fig. 2, which mainly includes three parts of the rectifying module 50, the inverting module 60, and the filtering module 70. The inside of compressor main part 10 is equipped with driving motor, and rectifier module 50 sets up at compressor main part 10 top and is located driving motor's top, and inverter module 60 arranges side by side with rectifier module 50, and inverter module 60 is located the top right side of compressor main part 10, and rectifier module 50 is then in the top left side of compressor main part 10. The refrigerant inlet pipe 11 and the refrigerant outlet pipe 12 can be arranged between the rectifying module 50 and the driving motor, and cooling to a certain extent of the rectifying module 50 and the driving motor is realized while the refrigerant is circularly conveyed.

An air supply duct with a preset width is formed between adjacent sides of the rectifying module 50 and the inverting module 60, and the heat exchanger assembly 30 is disposed at a first end of the air supply duct and is connected to the air outlet side of the air guide housing 34. The filtering module 70 is disposed on a side of the compressor body 10 away from the heat exchanger assembly 30, and since the filtering module 70 includes more capacitance elements, an installation area of the filtering module 70 is protruded toward a direction away from the heat exchanger assembly 30 on a side away from the heat exchanger assembly 30 relative to an edge portion of the compressor body 10. Circulating wind flowing out from the air outlet side of the heat exchanger assembly 30 can be respectively transmitted to the rectifying module 50, the inversion module 60 and the filtering module 70 under the cooperation of the air supply duct and the flow guiding assembly, and the circulating wind returns to the air inlet side of the heat exchanger assembly 30 after the temperature of the rectifying module 50, the inversion module 60 and the filtering module 70 is reduced.

With continued reference to FIG. 2, in some embodiments, the flow directing assembly includes a first fan 80 and a second fan 90, the first fan 80 and the second fan 90 preferably being axially offset, wherein the first fan 80 is disposed at a first end of the supply air duct, i.e., the second fan 90 is preferably offset from the supply air duct. The air inlet of the first fan 80 is communicated with the air outlet side of the air guide housing 34, the first fan 80 can be embedded in the air outlet side of the air guide housing 34, and the arrangement of the air guide housing 34 ensures that the distance between the air inlet of the first fan 80 and the second fins 33 is 20-30mm, so that the influence on the circulating air quantity is avoided. A baffle structure is arranged between the second end of the air supply duct and the filtering module 70, and air inlets respectively communicated with the rectifying module 50 and the inverting module 60 are arranged at two sides of the second end of the air supply duct.
