[0002] The main function of automobile air-conditioning pipelines is to transport refrigerant. They connect key components such as compressors, condensers, and evaporators to ensure the smooth operation of the refrigeration cycle. These pipelines can be divided into high-pressure pipes and low-pressure pipes according to pressure, and into gaseous pipes and liquid pipes according to the state of the refrigerant. Each of them is responsible for transporting the refrigerant at different stages. In addition, the air-conditioning pipeline requires a pipeline pressure plate and its matching structure to complete the fixation and installation of the pipeline.

[0003] Problems with existing technologies:

[0004] Regarding the pressure plate matching structure used to fix and install air-conditioning pipes, the temperature inside the car body will continue to be in a high temperature state when the car body is driving for a long time or exposed to the sun. The air-conditioning pipes receive two types of external heat. One is the temperature in the car engine compartment, and the other is the temperature of the car body structure directly transmitted to the pipe due to the pressure plate connector. Among them, the temperature in the engine compartment can be carried away by the airflow during driving, while the heat conducted by the pressure plate connector cannot be directly and quickly dissipated. Therefore, there is an urgent need for a pressure plate matching structure with good heat dissipation effect. Utility Model Content

[0025] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0026] like Figure 1-Figure 5 As shown, a car air conditioning pipeline pressure plate matching structure includes a hot liquid pipe 2 and a cold liquid pipe 5, the first and second ends of the hot liquid pipe 2 are respectively connected to a generator with an evaporator unit 1 and a compressor 3, the output end of the compressor 3 is connected to a radiator 4 through a pipeline, and the first and second ends of the cold liquid pipe 5 are respectively connected to the radiator 4 and the generator with an evaporator unit 1.

[0027] According to the above structure, the compressor 3 compresses the refrigerant and sends it to the radiator 4 for cooling. The cooled refrigerant enters the generator evaporator unit 1 through the cold liquid pipe 5, and the refrigeration function is completed. This process is all existing technology and will not be described in detail here.

[0028] Refer to the attached Figure 1 and Figure 3 The hot liquid pipe 2 and the cold liquid pipe 5 are connected to the internal frame of the automobile through a pipeline matching structure 6. A component cooling structure is arranged inside the pipeline matching structure 6 to cool down the structural parts by utilizing the temperature difference between the hot liquid pipe 2 and the cold liquid pipe 5. A pressure plate guide 7 for generating airflow inside the pipeline matching structure 6 is fixedly installed on the inner side of the pipeline matching structure 6.

[0029] Refer to the attached Figure 2-Figure 4 The pipeline matching structure 6 is composed of a tube pressing plate 601 and a gap base 602. The gap base 602 is fixedly installed on both sides of the tube pressing plate 601 by screws, and the tube pressing plate 601 is fixedly installed inside the automobile frame through the gap base 602. The tube pressing plate 601 is integrally provided with a tube seat 603 for the hot liquid pipe 2 and the cold liquid pipe 5 to pass through, and the inside of the tube pressing plate 601 is communicated with the tube seat 603. The inner walls of the tube pressing plate 601 and the tube seat 603 are provided with a thermal insulation The inner shell 604 and the two tube seats 603 are both equipped with temperature-conducting cylinders 605, which are both fitted to the inner wall of the thermal insulation inner shell 604, and the two temperature-conducting cylinders 605 are respectively sleeved on the outer surfaces of the hot liquid tube 2 and the cold liquid tube 5, and the two temperature-conducting cylinders 605 are both integrally provided with temperature-conducting plates 606 on the opposite sides thereof, and the interior of the tube pressing plate 601 is embedded with a semiconductor 607, and the two sides of the semiconductor 607 are respectively fitted to the two temperature-conducting plates 606.

[0030] Refer to the attached Figure 2-Figure 4The inner side of the tube pressing plate 601 is provided with a fin plate 615 in an array-like integrated manner. The side wall of the tube pressing plate 601 and one side of the fin plate 615 are provided with through holes 616. A heat dissipation fan 614 is detachably installed on one side of the tube pressing plate 601. A temperature control trigger 608 is fixedly installed on the outer wall of one end of the tube pressing plate 601. The semiconductor 607 is electrically connected to the heat dissipation fan 614 and is disconnected by controlling the temperature control trigger 608. The lower half of the temperature control trigger 608 is a sliding assembly. A liquid plug 609 is installed, and the bottom of the temperature control trigger 608 is filled with kerosene 610. Conductive sheets 612 are fixedly installed on both sides of the inner wall at the top of the temperature control trigger 608. A conductor 611 is fixedly set on the top of the liquid plug 609. When the conductor 611 is attached to the two conductive sheets 612 at the same time, the semiconductor 607 supplies power to the heat dissipation fan 614. The outer wall of the temperature control trigger 608 is connected to the outer wall of the pressure tube plate 601 through a copper temperature conductive rod 613.

[0031] According to the above structure, the function of the thermal insulation inner shell 604 is to provide resistance in the process of heat conduction from the tube plate 601 to the heat conduction cylinder 605, thereby reducing the influence of the temperature of the tube plate 601 on the heat conduction cylinder 605. The hot liquid pipe 2 and the cold liquid pipe 5 respectively conduct their high and low temperatures to the corresponding heat conduction cylinder 605, and then conduct them to the two sides of the semiconductor 607 through the heat conduction plate 606. According to the characteristics of the semiconductor 607, it will generate current. At the same time, when the temperature of the outer wall of the tube plate 601 reaches a certain temperature, its heat is conducted to the temperature control trigger 608 through the copper heat conduction rod 613 and heats the kerosene 610. When the kerosene 610 expands to a certain extent due to the heat, the liquid plug 609 rises and makes the conductor 611 contact with the two conductive sheets 612, and then the semiconductor 607 will dissipate heat. The fan 614 is powered on. After the heat dissipation fan 614 is powered on, it cooperates with the fin plate 615 and the through hole 616 to cool the tube plate 601. The through hole 616 is designed to promote the circulation of air between the fin plates 615. The above process can provide power for the heat dissipation fan 614 with the help of the temperature difference between the hot liquid pipe 2 and the cold liquid pipe 5. After the heat dissipation fan 614 is working, it cooperates with the fin plate 615 and the through hole 616 to promote the circulation of air between the fin plates 615, so as to achieve the purpose of cooling the tube plate 601, solve the problem that traditional air-conditioning pipelines are easily received by the cover plate and other connectors during use, and reduce the influence of heat conduction of the connectors. In addition, only when the outer wall of the tube plate 601 reaches a certain temperature, the temperature control trigger 608 will trigger the semiconductor 607 to conduct electricity for the heat dissipation fan 614.

[0032] See attached Figure 5The pressure plate guide 7 includes two base frames 701 fixedly installed on the inner side of the gap base 602 and fan pieces 706 rotatably installed on the inner side of the gap base 602. The two base frames 701 are fixedly provided with outer tubes 702 at the opposite ends. An inner rod 703 is slidingly assembled between the two outer tubes 702, and a counterweight body 704 is fixedly provided on the outer wall of the middle part of the inner rod 703. Springs 705 are connected between the two ends of the counterweight body 704 and the two outer tubes 702. A connecting rod 707 is fixedly connected to the side wall of the counterweight body 704. The two ends of the connecting rod 707 are respectively connected to one end of the two fan pieces 706.

[0033] According to the above structure, when the vehicle body encounters bumps during driving, since the base frame 701, the gap base 602 and the vehicle body frame are in a fixed connection relationship, under the action of inertia, the counterweight body 704 and the inner rod 703 will produce relative movement with the outer tube 702, and the corresponding spring 705 will be squeezed or stretched. During the movement of the counterweight body 704, the connecting rod 707 can simultaneously carry two fan blades 706 for fanning, thereby promoting the flow of air inside the gap base 602. This pressure plate guide member 7 structure can make use of the bumps of the vehicle body during driving and cooperate with the gap base 602 set in the gap to promote the flow of air inside the gap base 602, solve the problem of heat accumulation inside the pipe cover plate structure, further reduce the temperature influence of the cover plate structure on the air-conditioning pipe, and reduce the efficiency of heat transfer.

[0034] The working principle of the utility model is as follows: the function of the heat-insulating inner shell 604 is to provide resistance in the process of heat conduction from the pressure tube plate 601 to the heat-conducting cylinder 605, thereby reducing the influence of the temperature of the pressure tube plate 601 on the heat-conducting cylinder 605. The hot liquid pipe 2 and the cold liquid pipe 5 conduct their respective high and low temperatures to the corresponding heat-conducting cylinder 605, and then conduct them to the two sides of the semiconductor 607 through the heat-conducting plate 606. According to the characteristics of the semiconductor 607, it will generate current. At the same time, when the temperature of the outer wall of the pressure tube plate 601 reaches a certain value, the heat-conducting plate 606 will generate current. When the temperature is set, the heat is transferred to the temperature control trigger 608 through the copper temperature conducting rod 613 and heats the kerosene 610. When the kerosene 610 expands to a certain extent due to the heat, the liquid plug 609 rises and makes the conductor 611 contact the two conductive sheets 612. Then the semiconductor 607 will energize the heat dissipation fan 614. After the heat dissipation fan 614 is energized, it can cool the tube plate 601 with the fin plate 615 and the through hole 616. The through hole 616 is designed to promote the circulation of air between the fin plates 615.

[0035] When the vehicle body encounters bumps during driving, since the base frame 701, the gap base 602 and the vehicle body frame are fixedly connected, under the action of inertia, the counterweight body 704 and the inner rod 703 will produce relative movement with the outer tube 702, and the corresponding spring 705 will be squeezed or stretched. During the movement, the counterweight body 704 can carry two fan blades 706 at the same time through the connecting rod 707 to fan, thereby promoting the flow of air inside the gap base 602.

[0036] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
