Abstract
Description
Technical Field
[0001] This utility model relates to a novel compressor discharge pipe assembly structure. Background Technology
[0002] The air conditioning system of a car consists of major structural components such as a compressor, condenser, and evaporator.
[0003] The refrigerant at the compressor outlet has a relatively high temperature, typically 60-100 degrees Celsius, and a high flow rate, ranging from 10 to 30 meters per second.
[0004] In existing technology, the compressor and condenser are directly connected via high-temperature resistant hoses. However, due to the limited space in the engine compartment, the hoses are usually in a bent state. (See [reference needed]). Figure 4 As shown, Figure 4 The middle pipe joint 81 and the hose 82 are bent near the pipe joint 82, causing the high-speed refrigerant sprayed out to impact a point on the inner wall of the hose for a long time, causing the hose to age rapidly at that location and eventually leading to refrigerant leakage.
[0005] To address this, we designed a novel compressor discharge pipe assembly structure that avoids direct refrigerant impact on the hose. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide a novel compressor discharge pipe assembly structure that avoids direct impact of refrigerant on the hose.
[0007] To solve the above problems, the present invention adopts the following technical solution:
[0008] A novel compressor discharge pipe assembly structure includes a hose and two connecting terminals installed at the ends of the hose. One connecting terminal is connected to the compressor, and the other connecting terminal is connected to the condenser. High-speed refrigerant flowing out of the compressor is delivered to the hose after the impact force is dispersed by the connecting terminals.
[0009] Preferably, the connecting terminal includes a pressure plate, an insertion tube is machined at the bottom of the pressure plate, a connecting tube is machined at the upper end of the pressure plate, a connecting hole is drilled on the surface of the pressure plate, an annular groove is machined on the outer wall of the connecting tube, the insertion tube and the connecting tube communicate with each other, multiple through grooves are distributed annularly at the bottom of the annular groove, and refrigerant passes through the through grooves, a sleeve is fitted on the outside of the connecting tube, the annular groove is located inside the sleeve, a side tube is welded on the outside of the sleeve, the side tube is connected to the flexible hose, a sealing ring is sandwiched between the sleeve and the connecting tube, multiple sealing rings are provided, respectively located on the upper and lower sides of the annular groove, a pressure cap is threaded to the upper end of the connecting tube, and the pressure cap is screwed down to fix the sleeve.
[0010] Preferably, sealing gaskets are fitted at both the upper and lower ends of the connecting pipe, and the pressure cap is screwed down to press the sealing gaskets.
[0011] Preferably, a boss is machined at the upper end of the connecting pipe, the diameter of the boss being smaller than the outer diameter of the connecting pipe. A groove is machined downwards at the top of the boss, the groove communicating with the connecting pipe. A piston plate is slidably installed in the groove, and a first sealing ring is fitted on the outer wall of the piston plate, forming a seal between the first sealing ring and the inner wall of the groove. A shaft is provided at the lower end of the piston plate, the lower end of the shaft being tapered with a diameter gradually decreasing downwards, and the lower end of the shaft being located between multiple through slots. A spring is fixed at the upper end of the piston plate, and the upper end of the spring is limited by the pressure cap.
[0012] Preferably, a first sealing gasket is fitted between the boss and the pressure cap.
[0013] Preferably, the two ends of the hose are injection molded to form large end portions, the side tubes are inserted into the large end portions, the side tubes are interference-fitted with the large end portions, the large end portions and the side tubes are fixed together by clamps, and a protective spring is fitted on the hose, the two ends of the protective springs are limited by the large end portions.
[0014] The beneficial effects of this utility model are: In this technical solution, through the combination of the designed annular groove and through groove, the refrigerant that was originally discharged directly is dispersed in an annular manner through the through groove, and then collected at the side pipe and fed into the hose, avoiding continuous impact on a single point of the hose over a long period of time, thus extending its service life.
[0015] Secondly, the sleeve position is rotatable, which can be flexibly adjusted according to the space in the engine compartment, keeping the hose in a straight line near the side pipe, further reducing the impact on the hose, making it suitable for widespread use. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0026] See Figure 1 The present invention discloses a novel compressor discharge pipe assembly structure, including a hose 1 and two connecting terminals 2 installed at the ends of the hose 1. One connecting terminal 2 is connected to the compressor, and the other connecting terminal 2 is connected to the condenser. The high-speed refrigerant flowing out of the compressor is delivered to the hose 1 after the impact force is dispersed by the connecting terminal 2.
[0027] In the above technical solution, the specially designed connection terminal 2 can absorb the relatively high-speed refrigerant discharged from the compressor. Compared with traditional technology, this avoids direct collision between the refrigerant and the hose 1, reduces the impact on the hose 1, and extends the service life of the equipment.
[0028] See Figure 2 and Figure 3 As shown, the connecting terminal 2 includes a pressure plate 21. An insertion tube 22 is machined at the bottom of the pressure plate 21, and a connecting tube 23 is machined at the upper end of the pressure plate 21. A connecting hole 24 is drilled on the surface of the pressure plate 21. An annular groove 25 is machined on the outer wall of the connecting tube 23. The insertion tube 22 and the connecting tube 23 are connected. Multiple through grooves 26 are distributed in a ring at the bottom of the annular groove 25. The refrigerant passes through the through grooves 26. A sleeve 27 is fitted on the outside of the connecting tube 23. The annular groove 25 is located inside the sleeve 27. A side tube 28 is welded on the outside of the sleeve 27. The side tube 28 is connected to the flexible hose 1. A sealing ring 29 is sandwiched between the sleeve 27 and the connecting tube 23. Multiple sealing rings 29 are provided and are located on the upper and lower sides of the annular groove 25, respectively. A pressure cap 210 is threaded to the upper end of the connecting tube 23. The pressure cap 210 is screwed down to fix the sleeve 27.
[0029] In the above technical solution, the design of the annular groove 25 and the through groove 26 is adopted so that the high-speed refrigerant discharged from the compressor is dispersed in an annular shape, and then collected at the hose 1 and delivered to the condenser, thus avoiding direct contact between the high-speed and high-temperature refrigerant and the hose 1.
[0030] Preferably, sealing gaskets 231 are fitted at both the upper and lower ends of the connecting pipe 23, and the pressure cap 210 is screwed down to press the sealing gaskets 231.
[0031] Sealing gasket 231 can increase the sealing performance.
[0032] See Figure 2 and Figure 3As shown, a boss 232 is machined at the upper end of the connecting pipe 23. The diameter of the boss 232 is smaller than the outer diameter of the connecting pipe 23. A groove 233 is machined downward at the top of the boss 232. The groove 233 communicates with the connecting pipe 23. A piston plate 234 is slidably installed in the groove 233. A first sealing ring 235 is clamped on the outer wall of the piston plate 234. The first sealing ring 235 forms a seal with the inner wall of the groove 233. A shaft 236 is provided at the lower end of the piston plate 234. The lower end of the shaft 236 is tapered and its diameter gradually decreases downward. The lower end of the shaft 236 is located between multiple through slots 26. A spring 237 is fixed at the upper end of the piston plate 234. The upper end of the spring 237 is limited by the pressure cap 210.
[0033] In the above technical solution, the shaft 236 can disperse the refrigerant and reduce the impact force of the refrigerant, allowing the refrigerant to enter the hose 1 more smoothly.
[0034] See Figure 2 and Figure 3 As shown, a first sealing gasket 2321 is fitted between the boss 232 and the pressure cap 210.
[0035] The first sealing gasket 2321 is to increase the sealing performance at the boss 232 and further prevent refrigerant leakage.
[0036] See Figure 2 As shown, the two ends of the hose 1 are injection molded to form large end portions 121. The side tube 28 is inserted into the large end portion 121. The side tube 28 and the large end portion 121 are interference-fitted. The large end portion 121 and the side tube 28 are fixed together by clamps. A protective spring 131 is fitted on the hose 1. The two ends of the protective spring 131 are limited by the large end portion 121.
[0037] When this pipe is laid out in the engine compartment, the protective spring 131 can provide external protection for the hose 1.
