DETAILED DESCRIPTION

[0042] The present invention will be further described below in detail with reference to the embodiments shown in the accompanying drawings.

[0043] Reference Figure 1 — Fig.12 As shown, the gas-liquid separator for new energy vehicles of this embodiment includes a shell 1 and an upper cover 2. One end of the shell 1 is open and connected to the upper cover 2. The upper cover 2 is provided with an input hole 21 and an output hole 22. A pipe 4 and a baffle 5 are provided in the shell 1. One end of the pipe 4 is connected to the output hole 22, and the other end extends to the other end of the shell 1. The baffle 5 is provided with a mounting hole 51. The pipe 4 is located in the mounting hole 51. There is an upper gap 52 between the baffle 5 and the upper cover 2. The other end of the shell 1 is open and A lower cover 3 is arranged at the opening position, the lower cover 3 is provided with a heat exchange inlet hole 31 and a heat exchange outlet hole 32, a heat exchange tube 6 is arranged in the shell 1, and the two ends of the heat exchange tube 6 are respectively connected to the heat exchange inlet hole 31 and the heat exchange outlet hole 32, a material exchange hole 33 is arranged in the lower cover 3, and a closing plate 34 is arranged on the material exchange hole 33, a detachable drying sleeve 7 is arranged in the shell 1, and a desiccant is arranged in the drying sleeve 7, and a through hole 71 is arranged on the drying sleeve 7, and the position of the drying sleeve 7 corresponds to the position of the material exchange hole 33.

[0044] Through the above technical solution, the heat exchange inlet hole 31 and the heat exchange outlet hole 32 are connected to the external pipeline, and the temperature of the medium inside the external pipeline is higher than the temperature inside the gas-liquid separator. When the automobile air conditioner is running, the medium enters from the heat exchange inlet hole 31 and passes through the heat exchange tube 6 and then leaves from the heat exchange outlet hole 32, exchanging heat with the medium in the gas-liquid separator, thereby ensuring the working temperature inside the gas-liquid separator, thereby improving the performance of the automobile air conditioner and the stability during operation.

[0045] The drying sleeve 7 is detachably arranged in the housing 1. When fixed, one end of the drying sleeve 7 wraps around the positioning seat 54 on the baffle 5 and contacts the baffle 5, and the other end contacts the closing plate 34. When replacing the desiccant, the closing plate 34 is removed to take out the drying sleeve 7, and the desiccant inside is replaced. After the replacement is completed, the drying sleeve 7 is vertically inserted into the lower cover 3. When inserted to the bottom, the drying sleeve 7 wraps around the positioning seat 54 on the baffle 5 and contacts the baffle 5, and then the closing plate 34 is used to close the material replacement hole 33. The desiccant can be replaced separately to reduce maintenance costs.

[0046] As an improved specific implementation, the heat exchange inlet hole 31 is located between the material exchange hole 33 and the pipe 4, the heat exchange outlet hole 32 is located on one side of the material exchange hole 33, and the material exchange hole 33 is located between the heat exchange inlet hole 31 and the heat exchange outlet hole 32. The heat exchange tube 6 includes:

[0047] The inlet portion 61 is arranged straightly, inserted into the heat exchange inlet hole 31 and connected thereto, and the inlet portion 61 is arranged parallel to the drying jacket 7 and the pipeline 4, and the inlet portion 61 is arranged adjacent to the pipeline 4 and the drying jacket 7;

[0048] The spiral portion 62 is arranged in a spiral bending manner and is connected to the inlet portion 61. The heat exchange tubes 6 of the spiral portion 62 are arranged in a spiral manner, and there is a gap between adjacent heat exchange tubes 6. The spiral portion 62 is located outside the inlet portion 61, the drying jacket 7, and the pipeline 4;

[0049] The exit portion 63 is arranged straight, one end of which is connected to the spiral portion 62, and the other end of which is inserted into the heat exchange outlet hole 32 and connected thereto;

[0050] The entry portion 61 , the spiral portion 62 , and the exit portion 63 are integrally formed.

[0051] Through the above technical scheme, the medium temperature in the entrance part 61 is the highest, and the entrance part 61 is arranged adjacent to the pipeline 4 and the drying sleeve 7, so that the gas-liquid separator and the drying can be carried out stably, thereby improving the stability during use; the heat exchange tube 6 of the spiral part 62 is spirally distributed on the outer side of the shell 1, and the pipeline 4 and the drying sleeve 7 are located in the area inside the spiral part 62, so the heat exchange area is large, the targeting is strong, and the effect is good; the exit part 63 is arranged straight, so that the heat exchange tube 6 is aligned with the heat exchange inlet hole 31 and the heat exchange outlet hole 32 of the lower cover 3 when installing, and then inserted vertically, and then fixed, which is convenient to install.

[0052] The entrance portion 61, the spiral portion 62, and the exit portion 63 are integrally formed, and have high structural strength.

[0053] As an improved specific embodiment, the pipeline 4 includes an inner tube 41 and an outer tube 42. The outer tube 42 is sleeved outside the inner tube 41 and is integrally formed with the inner tube 41. One end of the inner tube 41 passes through the outer tube 42 and is located in the mounting hole 51, and the other end is located in the outer tube 42. There is a lower gap 53 between the opening of the outer tube 42 and the baffle 5. The end of the outer tube 42 close to the lower cover 3 is an oil return portion 43. The oil return portion 43 is arranged in an arc shape, and an oil return hole 44 is provided at the end.

[0054] Through the above technical solution, the inner tube 41 and the outer tube 42 are integrally formed, fewer parts are required during assembly, and the assembly efficiency is high. Specifically, a filter screen is provided outside the oil return hole 44 .

[0055] When the refrigerant from the evaporator enters the shell 1 from the input hole 21, it is first located in the upper gap 52, and the gas-liquid mixture collides with the baffle 5. In this process, the gaseous refrigerant quickly passes through the gap between the baffle 5 and the shell 1 and enters the other side of the baffle 5 after colliding with the baffle 5. Then, the gaseous refrigerant collides with the liquid surface of the liquid refrigerant inside the shell 1 and moves upward (or moves upward after falling to the end of the movement trend). The gaseous refrigerant moves upward to collide with the baffle 5, and then moves to the lower gap 53, and then passes between the inner side surface of the outer tube 42 and the outer side surface of the inner tube 41. Then, once it reaches the lower end of the outer tube 42, the oil accumulated under the liquid refrigerant is sucked from the oil return hole 44 and turned upward and rose inside the inner tube 41. The oil-containing gaseous refrigerant is discharged from the output hole 22 and returns to the compressor.

[0056] As an improved specific implementation, a reinforcing rib 45 is provided between the inner tube 41 and the outer tube 42 , and the reinforcing rib 45 extends toward the baffle 5 and contacts the baffle 5 .

[0057] Through the above technical solution, the reinforcing ribs 45 improve the structural strength of the inner tube 41 and the outer tube 42. Specifically, the inner tube 41, the outer tube 42 and the reinforcing ribs 45 are integrally formed, and the structural strength is higher.

[0058] The reinforcing rib 45 extends toward the baffle 5 and contacts one end surface of the baffle 5, and the other end surface of the baffle 5 contacts the upper cover 2, so that the position is stable, avoiding shaking during use, thereby improving stability during use.

[0059] As an improved specific implementation, a locking groove 331 is provided on the side of the material exchange hole 33 , and a retaining spring 332 is provided in the locking groove 331 .

[0060] Through the above technical solution, after the closing plate 34 and the material exchange hole 33 are closed, one end of the material exchange plate contacts the drying sleeve 7, and the other end contacts the retaining spring 332, the position is stable, and the position of the drying sleeve 7 is also stable.

[0061] When disassembling the closing plate 34 , first remove the retaining ring 332 , then take out the material changing plate, and then take out the drying sleeve 7 .

[0062] During installation, the closing plate 34 is installed into the material exchange hole 33 so that it contacts the drying sleeve 7, and then the locking groove 331 is inserted into the locking groove. After the installation is completed, the position is stable.

[0063] As an improved specific implementation, a sealing groove 341 is provided on the side of the closing plate 34 , and a rubber ring 342 is provided in the sealing groove 341 .

[0064] Through the above technical solution, the rubber ring 342 is arranged in the sealing groove 341, the position is stable, the rubber ring 342 contacts with the material exchange hole 33 to perform sealing, and the sealing effect is good.

[0065] As an improved specific implementation, a positioning seat 54 is provided on the lower side of the baffle 5, a positioning recess 72 is provided on one side of the drying sleeve 7, and a positioning mechanism 73 is provided in the positioning recess 72. The positioning mechanism 73 includes:

[0066] The positioning pieces 731 have a plurality of pieces, all of which are rotatably disposed in the positioning recess 72 , and the number of the positioning pieces 731 corresponds to the number of turns of the spiral portion 62 ;

[0067] A positioning hole 732 is provided on the positioning piece 731;

[0068] The positioning rod 733 is disposed in the positioning hole 732 . The positioning rod 733 is provided with a positioning protrusion 734 . The positioning protrusion 734 has a plurality of pieces, which are disposed one by one on the upper side of the positioning sheet 731 .

[0069] Through the above technical solution, when installing the drying sleeve 7, the housing 1 and the drying sleeve 7 are first inverted. At this time, under the action of gravity, the positioning piece 731 is retracted into the positioning recess 72, and the drying sleeve 7 can smoothly enter the material exchange hole 33; until it is inserted into the bottom area, the positioning rod 733 contacts the baffle 5, and the positioning piece 731 is located at the lower side of the corresponding heat exchange tube 6 (the upper and lower relationship is determined by the existing inverted state), and then as the drying sleeve 7 continues to descend, the positioning rod 733 drives the positioning piece 731 to rotate through the positioning protrusion 734 until the end of the drying sleeve 7 wraps the positioning seat 54 and contacts the baffle 5. At this time, the positioning piece 731 contacts the corresponding heat exchange tube 6, and then the heat exchange hole is closed to complete the installation. After the installation is completed, the upper and lower ends of the drying sleeve 7 are limited by the baffle 5 and the closing plate 34, and the positioning rod 733 contacts the baffle 5, pressing the positioning piece 731 to the spiral portion 62, so that the position of the material exchange tube is stable, preventing the material exchange tube from loosening during the operation of the car, and improving the stability and service life during use. At the same time, the positioning piece 731 can conduct heat and directly connect the spiral portion 62 and the drying sleeve 7, thereby further improving the heat exchange effect and better maintaining the performance of the gas-liquid separator.

[0070] Specifically, some through holes 71 are arranged on both sides of the positioning recess 72. The heat exchange effect at this position is good, so that the internal desiccant can absorb moisture better.

[0071] Specifically, part of the through holes 71 is disposed on a side facing the entrance portion 61 , where the heat exchange effect is good, so that the internal desiccant can better absorb moisture.

[0072] As an improved specific implementation, an arc-shaped extrusion portion 7311 is provided at one end of the positioning piece 731 away from the drying sleeve 7 .

[0073] Through the above technical solution, the extrusion portion 7311 increases the contact area with the heat exchange tube 6, so that the positioning piece 731 can better press the heat exchange tube 6 to prevent it from loosening, while increasing the heat exchange area, thereby improving the heat exchange effect.

[0074] As an improved specific implementation, a clamping mechanism 8 is provided on the lower side of the baffle 5, and the clamping mechanism 8 is arranged adjacent to the positioning seat 54, and the clamping mechanism 8 includes:

[0075] A pressing seat 81, wherein the pressing seat 81 is fixed to the lower side of the baffle 5;

[0076] The abutment seat 82 is slidably connected with the pressing seat 81 and sleeved on the pressing seat 81. The position of the abutment seat 82 corresponds to the position of the positioning rod 733.

[0077] The pressing spring 83 is arranged in the pressing seat 81, the upper end of which abuts against the baffle 5, and the lower end of which abuts against the abutting seat 82;

[0078] A lower convex ring 811 is arranged on the outer side of the lower end of the pressing seat 81;

[0079] The upper convex ring 821 is disposed on the outer side of the upper end of the abutment seat 82 , and the upper convex ring 821 is located on the upper side of the lower convex ring 811 .

[0080] Through the above technical solution, during the installation of the drying sleeve 7 by the shell 1, the positioning rod 733 contacts the clamping mechanism 8, and the positioning rod 733 first contacts the abutment seat 82. As the clamping continues, the positioning rod 733 compresses the clamping spring 83 through the abutment seat 82. When the installation is completed, the clamping spring 83 is in a compressed state, and the positioning rod 733 is pressed by the abutment seat 82, so that the positioning sheet 731 fits the heat exchange tube 6.

[0081] The compression spring 83 can absorb the vibration during the operation of the car, and avoid irreversible deformation of the positioning piece 731, so that the positioning piece 731 can always fit with the heat exchange tube 6 during long-term use, thereby extending the service life and improving the stability during use.

[0082] The abutment seat 82 is fixed on the pressing seat 81 by means of an upper convex ring 821 and a lower convex ring 811 to prevent separation and ensure stability during use.

[0083] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
