Description

Technical Field

[0001] This utility model relates to the technical field of liquid receivers, and in particular to a liquid receiver for an air conditioning compressor. Background Technology

[0002] The air conditioning compressor is the core component of the refrigeration system, and its normal operation depends on clean, impurity-free refrigerant. The receiver-and-discharge tank, a key component in the air conditioning refrigeration system, is installed at the compressor's return end. Its main functions are gas-liquid separation, storing excess refrigerant, filtering impurities, and adsorbing moisture to prevent liquid refrigerant or impurities from entering the compressor, causing liquid slugging or wear, thus ensuring the compressor's safety and lifespan.

[0003] In existing technologies, traditional compressor receivers typically include a housing with an inlet pipe, an outlet pipe, and an internal filter. The filter screen is a key component for capturing solid impurities such as metal debris and welding oxides within the system. Currently, most receivers have their filters fixed inside the housing, usually located in the upper or middle part of the receiver, and connected to the outlet pipe or internal structure via welding or other methods.

[0004] However, this traditional structure has significant drawbacks: First, disassembly is extremely inconvenient when the filter becomes clogged due to impurities or requires regular maintenance and replacement. It often requires opening from the top of the reservoir, which not only leads to long maintenance times and high labor intensity but also easily introduces new contamination during repair. Second, some reservoirs using a bottom-filter structure have complex connection and sealing methods between the filter components and the housing, resulting in low reliability. Furthermore, disassembly may affect the stability of the upper inlet and outlet pipes, posing a risk of leakage. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] like Figures 1 to 3 As shown, a liquid receiver for an air conditioning compressor includes a liquid receiver housing 1, an inlet pipe 2, a snap-fit ​​seat 3, a support rod 4, a filter screen 5, a sealing plate 6, a drain pipe 7, an annular groove 8, a conical seat 9, a sealing ring 10, a "┓"-shaped guide plate 11, a top cover 12, and an exhaust valve 13.

[0025] The reservoir shell 1 is the main container.

[0026] The upper end of the side wall of the liquid receiver housing 1 is connected to the liquid inlet pipe 2, which is used for the refrigerant to flow in.

[0027] The lower end of the inside of the liquid storage tank housing 1 is provided with a snap-fit ​​seat 3. The side wall of the snap-fit ​​seat 3 is fixed to the inner wall of the liquid storage tank housing 1 by a support rod 4. The bottom of the snap-fit ​​seat 3 is abutting against a filter screen cylinder 5. The lower end of the filter screen cylinder 5 extends out of the bottom of the liquid storage tank housing 1 and is connected to a sealing plate 6. The sealing plate 6 is fixed to the bottom of the liquid storage tank housing 1 by bolts. A drain pipe 7 is provided on the snap-fit ​​seat 3. The lower end of the drain pipe 7 extends into the inside of the filter screen cylinder 5, and the upper end of the drain pipe 7 is bent and extends out of the side wall of the liquid storage tank housing 1.

[0028] The filter cylinder 5 is the core component, installed at the bottom and connected to the clip seat 3 at the top.

[0029] The sealing plate 6 is used to seal and fix the filter cylinder 5 from the bottom.

[0030] The drain pipe 7 passes through the snap-fit ​​seat 3 and extends into the filter cylinder 5 to drain the filtered liquid.

[0031] The bottom of the snap-fit ​​seat 3 is provided with an annular groove 8, and the top of the filter screen cylinder 5 is sealed and snapped into the annular groove 8. This ensures that the liquid before and after filtration are effectively separated, preventing unfiltered liquid from short-circuiting into the drain pipe 7.

[0032] The top of the snap-fit ​​seat 3 is provided with a conical seat 9, which guides the liquid to be evenly distributed and avoids direct impact on the connection between the snap-fit ​​seat 3 and the filter screen 5, while also helping the bubbles to separate and rise.

[0033] The lower end of the drain pipe 7 has a slanted cut structure, which can increase the suction port area.

[0034] A sealing ring 10 is provided between the sealing plate 6 and the bottom of the liquid storage tank 1.

[0035] A “┓”-shaped guide plate 11 is provided on the inner wall of the liquid receiver housing 1 at the upper end of the liquid inlet pipe 2 to change the direction of liquid inlet, prevent the high-speed flowing refrigerant from directly impacting the inner wall or liquid surface of the liquid receiver housing 1, reduce foam and turbulence, and promote gas-liquid separation.

[0036] A top cover 12 is detachably mounted on the top of the reservoir housing 1 via bolts, and an exhaust valve 13 is provided on the top cover 12. The top cover 12 facilitates internal cleaning and maintenance; the exhaust valve 13 is used to discharge air or non-condensable gases during system maintenance to ensure system operating efficiency.

[0037] The working principle of this utility model is as follows: refrigerant enters the interior of the receiver housing 1 through the inlet pipe 2; the liquid is filtered as it flows through the filter cylinder 5; the filtered clean liquid enters from the lower end of the drain pipe 7 and exits from its upper end, supplying the compressor. During maintenance, simply remove the bolts and sealing plate 6 at the bottom to easily remove the entire filter cylinder 5 downwards.

[0038] This utility model features convenient maintenance: the bottom-removable filter cylinder 5 design greatly simplifies the maintenance process and saves time and labor costs.

[0039] This utility model has functional integration: through detailed design such as the "┓"-shaped guide plate 11, the conical seat 9, and the oblique cut, it integrates multiple functions such as buffering, flow guiding, anti-clogging, high-efficiency filtration, and gas-liquid separation.

[0040] This utility model features structural reliability: through the design of annular groove 8 for sealing, bottom bolt fixing, and sealing ring 10, the sealing performance and service life of the equipment are ensured under frequent maintenance.
