Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically a constant temperature air conditioning heat exchanger. Background Technology

[0002] Finned constant temperature air conditioning heat exchangers are devices used to regulate temperature. They improve heat exchange efficiency by increasing the heat dissipation area. The working principle of finned constant temperature air conditioning heat exchangers is mainly based on the refrigerant flowing inside copper tubes, transferring heat to the fins through the copper tubes, and then exchanging heat with the air through the contact of the fins. This design allows the metal fins to effectively increase the heat dissipation area, thereby helping the copper tubes to dissipate or absorb heat more quickly. In addition, finned heat exchangers have a wide range of applications. They can be used not only in residential and commercial air conditioning systems, but also widely used in automotive air conditioning, air heating in drying systems, and many other fields.

[0003] In the existing technology, when an air conditioner heat exchanger works in a specific environment, such as an environment where dust or frost easily accumulates, its heat exchange performance may be affected. Therefore, it is necessary for staff to clean its interior regularly. However, air conditioner heat exchangers usually have copper tubes and fins installed in a casing, and the casing is then fixed by a large number of fixing bolts or welding. This results in numerous disassembly and assembly steps and slow disassembly and assembly speed, which affects the efficiency of heat exchanger maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a constant temperature air conditioning heat exchanger to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature air conditioning heat exchanger, comprising:

[0006] The frame body has mounting plates fixedly installed at the four corners on both sides of the frame body, and baffles are provided on the front and rear sides of the frame body. Limiting plates are fixedly installed at the four corners of the baffles away from the frame body. The limiting plates and the mounting plates have through grooves in their middle parts.

[0007] Multiple mounting pins are provided, each of which is disposed inside a set of through slots. Each mounting pin includes an outer sleeve that is adapted to each through slot. Four evenly distributed mounting grooves are provided on the outer side of the outer sleeve near the mounting support plate, and each mounting groove is provided with a limiting ball. An abutment block is slidably installed in the middle of the outer sleeve. A threaded rod is threadedly connected to the middle of the outer sleeve near the limiting support plate. A spring is provided in the middle of the outer sleeve.

[0008] Preferably, each threaded rod has an auxiliary handle fixedly installed at its end.

[0009] Preferably, each of the external sleeves is fixedly installed with a limiting plate on the side near the threaded rod. Each limiting plate has multiple evenly distributed positioning holes on the side near the limiting support plate, and each limiting support plate has a positioning protrusion that matches the positioning holes on the side near the limiting plate.

[0010] Preferably, both the through groove and the abutment block are chamfered.

[0011] Preferably, the frame body is provided with uniformly distributed tube groups and the outer periphery of the tube groups is provided with multiple uniformly distributed fins.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The constant temperature air conditioning heat exchanger proposed in this utility model is equipped with an installation support plate, a limiting support plate, and an installation pin. An auxiliary handle, in conjunction with a threaded rod, a spring, abutment block, and limiting ball bearings, allows for quick assembly and disassembly of the baffle and the frame body. Because the baffle is designed to be detachable, it is convenient for staff to clean and maintain the fins and tube assemblies inside the frame. Furthermore, after the baffle is separated from the frame body, the tube assemblies and fins inside will be fully exposed, further improving the space and convenience for inspection and maintenance.

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a constant temperature air conditioning heat exchanger, comprising: a frame body 1, with mounting plates 4 fixedly installed at the four corners on both sides of the frame body 1, baffles 3 on the front and rear sides of the frame body 1, and limiting plates 6 fixedly installed at the four corners of the baffles 3 away from the frame body 1, with through grooves 5 opened in the middle of the limiting plates 6 and the mounting plates 4; multiple mounting pins 7, each mounting pin 7 being respectively set inside each set of through grooves 5, each mounting pin 7 including an outer sleeve 77, the outer sleeve 77 being adapted to the through grooves 5, four evenly distributed mounting grooves 76 opened on the outer side of the outer sleeve 77 near the mounting plates 4, and each mounting groove 76 being provided with limiting balls 75, an abutment block 78 slidably installed in the middle of the outer sleeve 77, a threaded rod 72 threadedly connected to the middle of the outer sleeve 77 near the limiting plates 6, and a spring 79 provided in the middle of the outer sleeve 77. Plate 6 is aligned with mounting support plate 4 on frame body 1. At this time, mounting pin 7 is placed in through groove 5. By rotating auxiliary handle 71, threaded rod 72 can rotate. Due to the characteristics of the thread, threaded rod 72 will compress internal spring 79, and then abutment block 78 will move towards limit ball 75. When the chamfered position of abutment block 78 contacts limit ball 75, limit ball 75 will move out of mounting groove 76. Since the diameter of the edge of mounting groove 76 is slightly smaller than that of limit ball 75, limit ball 75 will not detach from mounting groove 76. When limit ball 75 moves out of limit groove, limit ball 75, in conjunction with the chamfered position of through groove 5, can firmly fix baffle 3 to frame body 1. If the operation is reversed, mounting pin 7 will detach from through groove 5. At this time, mounting pin 7 can be removed, which makes it convenient for staff to quickly open frame body 1, facilitate internal maintenance and daily cleaning of heat exchanger, and ensure normal use of heat exchanger.

[0021] Auxiliary handles 71 are fixedly installed at the ends of the threaded rods 72. The auxiliary handles 71 facilitate the rotation of the threaded rods 72 by the workers. The auxiliary handles 71 are flat to increase their bearing area and make them easier for workers to use. Limiting plates 74 are fixedly installed on the side of the external sleeves 77 near the threaded rods 72. Multiple evenly distributed positioning holes 73 are provided on the side of the limiting support plate 6 near the limiting plate 74. At the same time, positioning protrusions that match the positioning holes 73 are provided on the side of the limiting support plate 6 near the limiting plate 74. By setting the positioning holes 73 and positioning protrusions, it is not only convenient for workers to place the installation pins 7 in the through grooves 5, but also to prevent the external sleeves 77 from rotating synchronously when the threaded rods 72 are rotated, which would affect the limiting of the limiting ball 75 on the baffle 3. The through grooves 5 and the abutment blocks 78 are both chamfered. The frame body 1 is provided with evenly distributed pipe groups 2 and multiple evenly distributed fins are provided on the outer periphery of the pipe groups 2.

[0022] In practical use, finned heat exchangers may be used in specific environments, such as those prone to dust accumulation or frost, which may affect their heat exchange performance. In such cases, staff need to clean and maintain the interior of the heat exchanger. Staff can use the auxiliary handle 71 to rotate the threaded rod 72. With the help of the thread, the threaded rod 72 reduces the pressure on the spring 79. The abutment block 78 then moves with the spring 79 until the limiting ball 75 loses its limit. The limiting ball 75 then moves into the mounting groove 76, thus limiting the mounting pin 7 against the baffle 3. At this point, staff can remove the baffle 3 and clean the interior of the finned heat exchanger. After cleaning, the normal operation of the heat exchanger is ensured, its heat exchange efficiency is not affected, and its constant temperature operation is maintained.

[0023] Although the illustrative specific embodiments of this application have been described above to enable those skilled in the art to understand this application, this application is not limited to the scope of the specific embodiments. For those skilled in the art, all applications utilizing the concept of this application are protected as long as various variations are within the spirit and scope of this application as defined and determined by the appended claims.
