[0015] 1. The heat dissipation structure of the automobile air-conditioning speed regulating module is achieved by connecting the heating resistor to the inside of the air-conditioning control circuit, and then embedding it into the groove on the top of the fixing plate, and then buckling the heat conducting plate on the top of the heating plate.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 3 In this embodiment, a heat dissipation structure of an automobile air-conditioning speed regulating module includes a heat dissipation top plate 1, a mounting component 2 arranged on the front side of the heat dissipation top plate 1, and an auxiliary component 3 arranged on the bottom side of the heat dissipation top plate 1.

[0023] Heat dissipation is performed by providing a heat dissipation top plate 1 and an auxiliary component 3 , and the mounting component 2 fixes the heating resistor inside between the heat dissipation top plate 1 and the auxiliary component 3 , thereby achieving a good heat dissipation effect.

[0024] In this embodiment, the mounting assembly 2 includes a fixing plate 21 fixedly mounted on the top of the heat dissipation top plate 1, a heating resistor 22 movably connected to the top of the fixing plate 21, a heat conducting plate 23 movably connected to the top of the heating resistor 22, a plurality of positioning buckles 24 movably connected to the top of the heat conducting plate 23, a positioning rod 25 threadedly connected to the top of the positioning buckle 24, and a guide plate 26 fixedly mounted on the top of the heat conducting plate 23.

[0025] A fixing plate 21 is provided to cooperate with the heat conducting plate 23 to limit and fix the heating resistor 22. The positioning rod 25 cooperates with the positioning buckle 24 to fix the heat conducting plate 23 and the heating resistor 22 on the top of the fixing plate 21. The guide plate 26 transfers the heat of the heat conducting plate 23 to the flowing air.

[0026] It should be noted that the fixing plate 21 and the guide plate 26 are both made of materials with good thermal conductivity.

[0027] In this embodiment, a groove is formed on the top of the fixing plate 21 , the bottom of the heating resistor 22 is embedded in the groove and is slidably connected to the inner wall of the groove of the fixing plate 21 , and a plurality of locking grooves 27 are formed on the side of the fixing plate 21 .

[0028] The heating resistor 22 is limited by providing a groove on the top of the fixing plate 21 to prevent the heating resistor 22 from moving and affecting the heat dissipation, and the sliding connection between the two facilitates later maintenance.

[0029] In this embodiment, a groove is formed at the bottom of the heat conducting plate 23 , and the top of the heating resistor 22 is embedded in the groove of the heat conducting plate 23 and is slidably connected to the inner wall of the groove of the heat conducting plate 23 .

[0030] The heating resistor 22 is limited by providing a groove at the bottom of the heat conducting plate 23 , so that the heat conducting plate 23 cooperates with the fixing plate 21 to smoothly ensure that the position of the heating resistor 22 is fixed.

[0031] It should be noted that the inside of the grooves of the heat conducting plate 23 and the fixing plate 21 can be coated with thermal conductive agents such as silicone grease to assist in heat dissipation. The depth of the groove is less than the thickness of the heating resistor 22 and will not affect the circuit connection of the heating resistor 22.

[0032] In this embodiment, the positioning buckle 24 is an E-shaped structure, the bottom of the positioning buckle 24 is embedded in the interior of the positioning groove 27 and is slidably connected to the inner wall of the positioning groove 27, and the side of the heat conducting plate 23 is embedded in the notch of the positioning buckle 24 and is slidably connected to the positioning buckle 24.

[0033] By providing the special-shaped positioning buckle 24 to be embedded in the locking groove 27, the heat conducting plate 23, the heating resistor 22 and the fixing plate 21 form a layered structure, thereby ensuring good stability and heat dissipation efficiency.

[0034] In this embodiment, threaded holes are provided at the tops of the positioning buckle 24 and the heat conducting plate 23, and a threaded column is provided at the bottom of the positioning rod 25. The bottom of the positioning rod 25 is embedded in the heat conducting plate 23 and is threadedly connected to the positioning buckle 24 and the heat conducting plate 23.

[0035] By setting threaded holes inside the positioning buckle 24 and the heat conducting plate 23 and then cooperating with the positioning rod 25 for threaded connection and limitation, the stability of the overall structure and the tightness of the contact are ensured, thereby ensuring the heat dissipation efficiency.

[0036] In this embodiment, the guide plate 26 is a semicircular aluminum plate that fits together. The side of the guide plate 26 is provided with a plurality of through grooves that penetrate the inner and outer side walls of the guide plate 26 . The center of the guide plate 26 is at different positions on a line.

[0037] By providing an arc-shaped guide plate 26 on the top of the heat conducting plate 23 for cooperation, when air circulates inside the heat dissipation top plate 1, since the guide plate 26 is on the top of the heat conducting plate 23, the air temperature inside the guide plate 26 is higher than the air outside it. When the air circulating outside passes between the guide plates 26, a spiral upward airflow is formed inside the guide plate 26, thereby ensuring the heat dissipation efficiency inside the heat conducting plate 23.

[0038] In this embodiment, the auxiliary component 3 includes a heat transfer aluminum sheet 31 fixedly mounted on the bottom of the heat transfer top plate 1 , a mounting plate 32 fixedly mounted on the side of the heat transfer aluminum sheet 31 , and a plurality of heat transfer bottom plates 33 fixedly mounted on the bottom of the heat transfer aluminum sheet 31 .

[0039] By arranging a heat transfer aluminum sheet 31 at the bottom of the heat dissipation top plate 1, the heat absorbed by the heat dissipation bottom plate 33 is transferred downward, and the heat is dissipated secondary through the heat dissipation bottom plate 33, thereby improving the heat dissipation efficiency.

[0040] In this embodiment, a mounting hole groove is provided on the surface of the mounting plate 32 , a plurality of guide grooves are provided on the bottom of the heat dissipation bottom plate 33 , and a plurality of heat dissipation fins are provided on the top surface of the heat dissipation top plate 1 .

[0041] Mounting holes are set on the surface of the mounting plate 32 to install the structure, and a guide groove is opened at the bottom of the heat dissipation base plate 33 to increase the contact area between the bottom of the heat dissipation base plate 33 and the air, thereby improving the heat dissipation efficiency. Heat dissipation fins are set on the top of the heat dissipation top plate 1 to increase the contact area and improve the heat dissipation efficiency.

[0042] The working principle of the above embodiment is:

[0043] After connecting the heating resistor 22 to the inside of the air-conditioning control circuit, it is embedded into the groove on the top of the fixing plate 21, and then the heat conducting plate 23 is buckled on the top of the heating plate 22. While the positioning buckle 24 is embedded into the inside of the positioning groove 27, the side of the heat conducting plate 23 is embedded into the inside of the notch on the side of the positioning buckle 24, and then the positioning rod 25 is screwed into the threaded holes inside the positioning buckle 24 and the heat conducting plate 23 in sequence, thereby realizing the overall installation of the heat dissipation structure.

[0044] In addition, after the heat on the top of the heating resistor 22 is absorbed by the heat conducting plate 23, the heat is transferred to the guide plate 26 through the heat conducting plate 23. The flowing air reaches the central position of the heat dissipation top plate 1 after passing through the gap formed by the heat dissipation fins of the heat dissipation top plate 1, takes away the heat accumulated on the guide plate 26, and then passes through the heat dissipation fins again, thereby realizing the transfer flow of heat on the top of the heating resistor 22. The fixing plate 21 transfers the heat dissipated by the heating resistor 22 to the heat dissipation top plate 1. The top heat dissipation fins of the heat dissipation top plate 1 dissipate part of the heat into the air, while part of the heat passes through the heat transfer aluminum sheet 31 to the heat dissipation bottom plate 33. The air takes away the heat of the heat dissipation bottom plate 33 through the guide groove at the bottom of the heat dissipation bottom plate 33, thereby realizing heat dissipation, thereby solving the problem of low efficiency caused by the heat dissipation design defects of the automobile air-conditioning speed regulation module.

[0045] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
