At the same time, it also needs to cooperate with the overall electronic system of the car to ensure the stable operation of the air-conditioning system.
[0003] The air conditioning speed control module of the car will generate heat when working, so an effective heat dissipation design is required, such as using a combination of thermal grease, heat sink and blower to dissipate heat in time. In addition, in order to prevent water vapor and water droplets condensed from the radiator from entering the module, the connection parts of the radiator usually need to be waterproof, such as using one-piece injection molding, sealant or sealing gasket. In addition, the structural design of the speed control module needs to ensure that it can remain stable under various conditions of use, such as using retaining rings and adhesive sealing connections to improve product reliability. Because the speed control module needs to take into account its waterproof performance, the improvement of its waterproof performance makes its sealing performance affect the heat dissipation effect to a certain extent. Therefore, a speed control module with high stability is proposed to ensure its sealing performance while avoiding its poor heat dissipation effect, resulting in low stability and affecting work efficiency.

DETAILED DESCRIPTION
[0022] 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.
[0023] See also Figures 1 to 4 In this embodiment, a speed control module with high stability includes a base 1, a heat dissipation component 2 arranged on the top of the base 1, an auxiliary component 3 arranged on the top of the base 1, and an adjustment component 4 arranged on the top of the auxiliary component 3.
[0024] The heat dissipation effect of the control module is achieved by arranging the heat dissipation component 2 in cooperation with the auxiliary component 3, and the base 1 cooperates with the auxiliary component 3 and the adjustment component 4 to form a sealing mechanism of the module.
[0025] In the present example, the heat dissipation assembly 2 includes a plurality of heat-conducting rods 21 fixedly mounted inside the base 1, a heat-conducting plate 22 fixedly mounted on the top of the heat-conducting rod 21, a heat dissipation plate 23 fixedly mounted on the top of the heat-conducting plate 22, a mounting base 24 fixedly mounted on the top of the heat dissipation plate 23, an adjustment resistor 25 snap-connected to the top of the mounting base 24, a PCB board 26 fixedly mounted on the top of the adjustment resistor 25, and a heat exhaust plate 27 fixedly mounted on the bottom of the heat-conducting rod 21.
[0026] A heat conducting rod 21 is provided to cooperate with a heat conducting plate 22 to transfer the heat generated by the regulating resistor 25, and the heat is discharged through the heat conducting rod 21 and a heat dissipation plate 27. The mounting seat 24 fixes the regulating resistor 25 on the heat conducting plate 22 to prevent displacement. The PCB board 26 connects the regulating resistor 25 to the control circuit.
[0027] It should be noted that the adjustment resistor 25 is connected to the control circuit through the PCB board 26, and the bottom of the base 1 is provided with a circuit inlet and outlet and is sealed by a sealant filling method.
[0028] In this example, a connecting seat 28 is fixedly installed on the inner bottom wall of the base 1, and a fixing rod 29 that passes through the bottom wall of the base 1 is rotatably connected inside the connecting seat 28. A snap groove is opened on the top of the base 1, and a sealant is provided inside the snap groove.
[0029] The connection base 28 is arranged on the inner bottom wall of the base 1 to cooperate with the fixing rod 29 and the auxiliary component 3 for connection and fixing, thereby enhancing the stability of the overall structure.
[0030] In this example, a positioning groove is provided on the top of the heat sink 23, the bottom of the mounting seat 24 is embedded in the positioning groove and fixedly mounted to the heat sink 23, and the bottom of the adjusting resistor 25 is fixedly mounted to the bottom wall of the positioning groove of the heat sink 23.
[0031] By setting a mounting base 24, the adjusting resistor 25 is fixedly mounted on the top of the heat sink 23, thereby ensuring the stability of the adjusting resistor 25 on the top of the heat sink 23. At the same time, the bottom of the adjusting resistor 25 is fixedly mounted on the top of the heat sink 23, so that the heat of the adjusting resistor 25 can be smoothly transferred to the heat sink 23.
[0032] In this example, the auxiliary component 3 includes a middle frame 31 snap-connected to the top of the base 1, a plurality of heat transfer rods 32 fixedly mounted on the side walls of the middle frame 31, a heat absorbing plate 33 fixedly mounted on the sides of the heat transfer rods 32, and a cooling plate 34 fixedly mounted on the sides of the heat transfer rods 32.
[0033] By arranging a heat transfer rod 32 and a heat absorbing plate 33 on the side wall of the middle frame 31, the heat of the air inside the module is assisted to be absorbed. Since the temperature of the cooling plate 34 is relatively low, the heat is transferred to the cooling plate 34 through the heat transfer rod 32, and then taken away by the external air.
[0034] In this example, an embedding plate is provided at the bottom of the middle frame 31, which is embedded in the buckle groove at the top of the base 1 and fixed to the base 1 by buckles. A locking nut 35 is fixedly installed on the side of the middle frame 31. The top of the fixing rod 29 is embedded in the interior of the locking nut 35 and is connected to the locking nut 35 by threaded rotation. A buckle groove is opened at the top of the middle frame 31, and a sealant is provided inside the buckle groove.
[0035] By providing a snap connection between the base 1 and the middle frame 31 and sealing with sealant, the sealing performance of the connection between the middle frame 31 and the base 1 is ensured, and the fixing rod 29 is screwed into the locking nut 35 to additionally fix the base 1 and the middle frame 31.
[0036] In this example, the adjustment assembly 4 includes a top plate 41 snap-connected to the top of the middle frame 31, a fixing seat 42 fixedly installed at the bottom of the top plate 41, a threaded sleeve 43 fixedly installed inside the fixing seat 42, and an adjustment rod 44 rotatably connected inside the threaded sleeve 43.
[0037] The top plate 41 is arranged to cooperate with the fixing seat 42 to fix the threaded sleeve 43, so that the adjusting rod 44 is rotated and moves up and down under the influence of the internal thread of the threaded sleeve 43, thereby pressing the PCB board 26 to maintain fixation.
[0038] In this example, an embedding plate is provided at the bottom of the top plate 41 , and the embedding plate is embedded in the buckle groove at the top of the middle frame 31 and is fixed to the middle frame 31 by buckles.
[0039] By providing a snap connection between the top plate 41 and the middle frame 31 , the connection and fixation are performed, and later disassembly and maintenance are facilitated.
[0040] In this example, the threaded sleeve 43 vertically penetrates the top plate 41 and is fixedly mounted to the top plate 41 , and the adjusting rod 44 vertically penetrates the threaded sleeve 43 and is rotationally connected to the threaded sleeve 43 via threads.
[0041] By setting a threaded sleeve 43 inside the top plate 41 and matching it with an adjusting rod 44, the adjusting rod 44 can be rotated to control the internal position of the adjusting rod 44 in the threaded sleeve 43. The position of the adjusting rod 44 is raised or lowered to press the top of the PCB board 26 to fix the top of the PCB board 26.
[0042] The working principle of the above embodiment is:
[0043] By fixing the adjusting resistor 25 to the bottom of the PCB board 26, and then fixing the bottom of the adjusting resistor 25 to the inside of the mounting base 24, the mounting base 24 is embedded in the groove of the heat sink 23, and then the middle frame 31 is embedded in the top of the base 1, and the top plate 41 is embedded in the top of the middle frame 31, and the fixing rod 29 is rotated and screwed into the inside of the locking nut 35, the installation of the entire module can be completed, and the adjusting rod 44 is rotated. The threaded rotation of the adjusting rod 44 in the threaded sleeve 43 causes the height of the adjusting rod 44 to change, thereby squeezing the PCB board 26. The PCB board 26 is squeezed to fix the adjusting resistor 25 and the mounting base 24 on the top of the heat sink 23, thereby realizing the installation of the module.
[0044] In addition, by providing a mounting base 24 on the bottom side of the adjusting resistor 25 to cooperate with and fix it on the top of the heat sink 23, the heat generated by the adjusting resistor 25 when in use will be dissipated into the air inside the module through the heat sink 23, and part of the heat will be transferred to the heat exhaust plate 27 through the heat conducting rod 21, thereby dissipating the heat inside the module, and the heat absorbing plate 33 absorbs the heat in the internal air and transfers it to the heat transfer rod 32, and the heat transfer rod 32 transfers the heat to the cooling plate 34 on the outside of the middle frame 31, and the air outside the module then takes away the heat on the cooling plate 34, thereby further enhancing the heat discharge inside the module, thereby ensuring the heat dissipation effect of the internal adjusting resistor 25, thereby solving the problem of poor heat dissipation performance of the traditional speed control module leading to reduced work efficiency.

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.
