Description

Technical Field

[0001] This utility model relates to the field of air conditioner accessories, and more specifically, to an air conditioner radiator fixing plate. Background Technology

[0002] The radiator is an important component of the air conditioning system. In the refrigeration cycle, the compressor compresses the refrigerant from a low-temperature, low-pressure gas into a high-temperature, high-pressure gas. The gas is then condensed into a medium-to-high-temperature liquid by the radiator, throttled by the expansion valve, and becomes a low-temperature, low-pressure liquid. It then absorbs heat and evaporates in the evaporator to become a low-temperature, low-pressure vapor, which is then sent back to the compressor.

[0003] Currently, the integration and lightweighting of air conditioning systems have become mainstream trends. To overcome the space constraints of the engine compartment layout, the connection between the radiator inlet and outlet and the piping is widely adopted in a combined manner, that is, the radiator inlet and outlet are integrated on the same pressure plate. However, this method has certain problems. Because the radiator outlet outputs medium-temperature liquid, while the radiator inlet inputs high-temperature gas, heat will be exchanged at the end of the pressure plate near the radiator outlet and the end near the radiator inlet. This will cause the subcooling of the radiator outlet (the difference between the saturated liquid temperature corresponding to the radiator condensing pressure and the actual temperature of the radiator outlet) to decrease, resulting in a decrease in the COP (actual energy efficiency ratio) of the air conditioning system. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an air conditioner radiator fixing plate. The fixing plate is provided with an output hole for connecting the output end of the radiator to an external pipeline and an input hole for connecting the input end of the radiator to an external pipeline. A detachable heat insulation unit is provided between the input hole and the output hole. The heat insulation unit is used to limit the heat transfer on the fixing plate between the input hole and the output hole. A collar is fitted on the outside of the heat insulation unit, which is limited and fixed by the external pipeline.

[0005] In a preferred embodiment, the length of the collar is greater than the length of the positioning frame and less than the distance between the input hole and the output hole.

[0006] In a preferred embodiment, the fixed pressure plate includes a first plate and a second plate arranged symmetrically, with an output hole and an input hole respectively provided on the first plate and the second plate, and screw holes that cooperate with the heat insulation unit are opened on the outer walls of the first plate and the second plate that are close to each other.

[0007] In a preferred embodiment, the heat insulation unit includes a positioning frame located between the first plate and the second plate, the positioning frame having a hollow heat insulation chamber filled with porous ceramic blocks.

[0008] In a preferred embodiment, a screw rod that is inserted into a screw hole is fixedly installed on the outer wall of the positioning frame facing the first plate and the second plate.

[0009] In a preferred embodiment, a recessed first limiting groove is formed on the outer wall of the first plate and the second plate that are close to each other, and a second limiting groove that cooperates with the first limiting groove is formed on the outer wall of the positioning frame facing the first plate and the second plate.

[0010] In a preferred embodiment, a matching limiting strip is inserted into the third limiting groove, with both ends of the limiting strip flush with the surface of the fixed pressure plate, and the limiting strip is located inside the collar.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0018] like Figure 1-3The air conditioner radiator fixing plate 1 shown has an output hole 2 for connecting the output end of the radiator to an external pipeline and an input hole 3 for connecting the input end of the radiator to an external pipeline. A detachable heat insulation unit 4 is provided between the input hole 3 and the output hole 2. The heat insulation unit 4 is used to limit the heat transfer on the fixing plate 1 between the input hole 3 and the output hole 2. A collar 5 is sleeved on the outside of the heat insulation unit 4, which is limited and fixed by the external pipeline.

[0019] Based on the above, the output hole 2 is used to connect the radiator output end to the external pipeline, and the input hole 3 is used to connect the radiator input end to the external pipeline. Since the temperature on the input hole 3 side is higher than that on the output hole 2 side, heat is easily transferred directly through the fixed pressure plate 1. Therefore, a heat insulation unit 4 is set between the two holes to reduce heat exchange through its physical barrier. The collar 5 is sleeved on the outside of the heat insulation unit 4. With the position constraint of the external pipeline, the heat insulation unit 4 is prevented from loosening or shifting during vibration, thus ensuring the stability of the heat insulation function.

[0020] It integrates input and output connection functions to fit the compact layout of air conditioners; the heat insulation unit 4 specifically blocks heat transfer and reduces the attenuation of subcooling at the radiator outlet; the collar 5 is fixed in conjunction with external pipelines to improve structural reliability under vibration environment.

[0021] The length of the collar 5 is greater than the length of the positioning frame 9 and less than the distance between the input hole 3 and the output hole 2. The length of the collar 5 is greater than the length of the positioning frame 9, so it can completely wrap the positioning frame 9 and ensure the radial constraint of the heat insulation unit 4. At the same time, the length is less than the distance between the two holes, so as to prevent the two ends of the collar 5 from extending into the area of ​​the input hole 3 or the output hole 2, so as not to interfere with the connection between the pipeline and the hole and ensure smooth fluid passage.

[0022] Furthermore, it not only effectively fixes the insulation unit 4, but also avoids interference with the connection to the pipeline. The structure is compact and suitable for small spaces.

[0023] The fixed pressure plate 1 includes a first plate 6 and a second plate 7 arranged symmetrically. The output hole 2 and the input hole 3 are respectively provided on the first plate 6 and the second plate 7. The outer walls of the first plate 6 and the second plate 7 that are close to each other are provided with screw holes 8 that cooperate with the heat insulation unit 4.

[0024] Based on the above, the first plate 6 and the second plate 7 are symmetrically distributed, separating the output hole 2 on the low temperature side and the input hole 3 on the high temperature side on two independent plates, thus reducing the direct heat conduction path from a structural perspective; the screw holes 8 on the near side of the two plates provide connection points for the heat insulation unit 4, and the heat insulation unit 4 and the two plates are assembled through detachable connection to form an integral fixed pressure plate 1;

[0025] The split design physically isolates the high and low temperature areas, reducing heat transfer; the screw hole 8 connection facilitates the installation of the insulation unit 4, taking into account both structural integrity and assembly flexibility.

[0026] The heat insulation unit 4 includes a positioning frame 9 located between the first plate 6 and the second plate 7. The positioning frame 9 has a hollow heat insulation chamber 10 inside, and the heat insulation chamber 10 is filled with porous ceramic blocks 11.

[0027] Based on the above, the positioning frame 9 serves as the supporting skeleton of the heat insulation unit 4, supporting it between the two plates. The heat insulation chamber 10 inside provides space for the heat insulation material. The porous ceramic block 11 filled in the chamber has a low thermal conductivity, which can significantly reduce the solid conduction heat between the first plate 6 and the second plate 7. At the same time, the hollow chamber reduces air convection heat conduction, thus limiting heat transfer in a dual way.

[0028] The positioning frame 9 is fixedly installed on the outer wall of the first plate 6 and the second plate 7, with a screw 12 inserted into the screw hole 8.

[0029] Based on the above, the screw 12 of the positioning frame 9 forms a threaded engagement with the screw holes 8 of the first and second plates 7. By rotating the positioning frame 9, the screw 12 is screwed into the screw hole 8. The self-locking force of the thread is used to tightly fix the positioning frame 9 between the two plates, avoiding the loosening of the heat insulation unit 4 caused by vibration, and ensuring that the heat insulation unit 4 is always in the key heat insulation position between the two holes.

[0030] Furthermore, the threaded connection is robust and reliable, and adaptable to vibration environments; the detachable design facilitates the replacement and maintenance of the insulation unit 4, reducing long-term operating costs.

[0031] A recessed first limiting groove 13 is provided on the outer wall of the first plate 6 and the second plate 7 that are close to each other. A second limiting groove 14 that cooperates with the first limiting groove 13 is provided on the outer wall of the positioning frame 9 facing the first plate 6 and the second plate 7. The first limiting groove 13 and the second limiting groove 14 are combined to form a third limiting groove 15.

[0032] Based on the above, the first limiting groove 13 and the second limiting groove 14 are in corresponding positions. When the positioning frame 9 is fixed to the two plates by the screw 12, the two grooves are spliced ​​to form a complete third limiting groove 15, which provides matching space for the subsequent installation of the limiting strip 16. The groove structure restricts the lateral relative displacement of the first plate 6, the second plate 7 and the positioning frame 9, and enhances the overall connection of the three.

[0033] A matching limiting strip 16 is inserted into the third limiting groove 15. The two ends of the limiting strip 16 are flush with the surface of the fixed pressure plate 1. The limiting strip 16 is located inside the collar 5.

[0034] Based on the above, the limiting strip 16 is inserted into the third limiting groove 15 and fits tightly against the groove wall, further restricting the relative movement of the first plate 6, the second plate 7 and the positioning frame 9 through physical engagement; the flush design at both ends avoids protruding from the pressure plate surface and does not interfere with external pipelines or installation space; located inside the collar 5, the collar 5 can form a radial wrapping constraint on the limiting strip 16, together with the limiting strip 16, to form a double limiting, enhancing the overall structural stability;

[0035] Furthermore, the dual constraint of the limit bar 16 and the collar 5 significantly improves the vibration and impact resistance; the flush design adapts to compact installation environments and avoids structural interference.

[0036] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
