[0023] As Figs. 1 to 3As shown, an integrated single-chip controller for a cold water machine can be embedded in the main machine to control the operation of the cold water machine, which includes a controller base shell 1. Wherein the top end face of the controller base shell 1 of the embodiment is provided with a mounting port 13, the mounting port 13 is embedded with a control panel 2, the controller base shell 1 also has a mounting cavity 14, the inside of the mounting cavity 14 is integrated with a control panel 3 for controlling the internal hardware units of the cold water machine and a mainboard 4 for receiving instructions from the control panel 2 to drive the control panel 3; the controller base shell 1 includes a heat dissipation part 11 and a mounting part 12 for embedding into the cold water machine from top to bottom, the heat dissipation part 11 is provided with an air inlet 111 and an air outlet 112 on both sides, respectively, and a heat dissipation mechanism 5 is arranged between the air inlet 111 and the air outlet 112 to promote air convection to dissipate heat.

[0024] The controller base shell 1 of the embodiment is designed to accommodate and protect the internal components, and has sufficient strength to ensure that deformation or damage does not occur during installation and use. Its top end face is provided with a mounting port 13, which is sized and shaped to fit the control panel 2 so that the control panel 2 can be securely embedded therein. The control panel 2 is the interface between the user and the controller, allowing the user to set parameters, monitor status, and perform other operations. The inside of the controller base shell 1 is provided with a mounting cavity 14, and the inside of the cavity is integrated with a control panel 3 and a mainboard 4. The control panel 3 is responsible for directly communicating with the hardware units inside the cold water machine and executing instructions from the mainboard 4; while the mainboard 4 serves as the core processing unit, receiving operation instructions from the control panel 2 and directing the work of the control panel 3 according to these instructions, by integrating the mainboard 4 and the control panel 3 in the base shell, the volume of the controller can be reduced, and the structure of the controller can be improved.

[0025] Specifically, the controller base shell 1 of the embodiment is composed of two parts, the lower part is the mounting part 12, which is shaped to fit the mounting groove on the shell of the cold water machine, and after the controller and the internal components such as the compressor, condenser, evaporator, etc. of the cold water machine are connected, it can be embedded into the mounting groove. The upper part is the heat dissipation part 11, the opposite sides of the side wall of the heat dissipation part 11 are respectively provided with an air inlet 111 and an air outlet 112, forming an air flow path from one side to the other side, and cooperating with the heat dissipation mechanism 5 to promote air circulation, thereby improving the heat exchange efficiency and effectively dissipating the heat generated inside the control panel 3.

[0026] As Fig. 2 and Fig. 3As shown, the heat dissipation mechanism 5 of the present embodiment comprises an air inlet heat dissipation fan 51 fixedly arranged inside the installation cavity 14 near the air inlet 111 and an air outlet heat dissipation fan 52 fixedly arranged inside the installation cavity 14 near the air outlet 112. The air inlet heat dissipation fan 51 can suck external air into the base from the air inlet 111, while the air outlet heat dissipation fan 52 can blow internal hot air out of the air outlet 112. The two work together to form an effective air flow channel from the air inlet 111 to the air outlet 112. This helps to accelerate the flow of air inside the controller and effectively take away heat from the inside of the controller through forced convection, preventing temperature accumulation.

[0027] As shown, Fig. 2 The opposite sides of the controller base 1 of the present embodiment are provided with displacement grooves 61, and each displacement groove 61 movably has a push-pull buckle 62 for detachable installation of the controller base 1. The push-pull buckle 62 comprises a buckling portion 621 located at the installation portion 12 and a movable portion 622 integrally formed with the buckling portion 621 and located at the heat dissipation portion 11. The movable portion 622 can be displaced along the displacement groove 61 to drive the buckling portion 621 to move into the displacement groove 61, thereby canceling the fixation. Specifically, displacement grooves 61 are formed on the other two sides of the base in addition to the air inlets 111 and the air outlets 112. The displacement grooves 61 extend downward from the heat dissipation portion 11 of the side wall of the base to the installation portion 12, and the push-pull buckles 62 are installed in the displacement grooves 61. The push-pull buckle 62 comprises the buckling portion 621 and the movable portion 622, which are integrally formed. The buckling portion 621 is located in the displacement groove 61 at the installation portion 12, and the movable portion 622 is located in the displacement groove 61 at the heat dissipation portion 11. When the push-pull buckle 62 is in the locked state, the buckling portion 621 can be firmly fixed at the installation groove in the water chiller main machine shell, and when it needs to be unlocked, only the movable portion 622 needs to be pushed to displace along the displacement groove 61, thereby driving the integral buckling portion 621 to hide in the inside of the displacement groove 61, realizing the release and unlocking of the controller.

[0028] As shown, Fig. 2 Each displacement groove 61 of the present embodiment also has a plurality of reset springs 63. One end of the reset spring 63 is fixedly connected to the push-pull buckle 62, and the other end is fixedly connected to the inner wall of the displacement groove 61. Each displacement groove 61 is provided with two reset springs 63, one end of each reset spring 63 is fixedly abutted against the back of the push-pull buckle 62, and the other end is fixedly abutted against the inner wall of the displacement groove 61. When an external force acts on the push-pull buckle, the push-pull buckle 62 will move along the displacement groove 61. Once the external force disappears, the reset spring 63 can quickly pull the push-pull buckle back to the initial position, realizing automatic reset.

[0029] As shown, Fig. 2As shown, the control panel 2 of the embodiment is integrally formed with a clamping hook 21 on the back of both sides, which can be detachably fixed in the mounting port 13. The control panel 2 can be fixed in the mounting port 13 by simple pressing action, and when maintenance or replacement of the control panel 2 is needed, it can be easily removed by simply pulling.

[0030] In summary, the embodiment has the following advantages: by integrating the control panel 3 and the main board 4 inside the controller base shell 1, the overall volume of the controller is effectively reduced, and the structure is more compact and beautiful. The heat dissipation part 11 on both sides is designed with an air inlet 111 and an air outlet 112, and is equipped with an air inlet cooling fan 51 and an air outlet cooling fan 52, thereby forming an efficient air flow channel. By forced convection, the heat generated inside the controller can be quickly removed, avoiding temperature accumulation and ensuring stable operation of the equipment. In addition, the controller base shell 1 is provided with a displacement slot 61 on both sides, and is internally provided with a push-pull buckle 62, so that the installation and disassembly of the controller is more convenient and rapid, and the push-pull buckle 62 cooperates with the reset spring 63 to provide an automatic reset function. The integrated clamping hook 21 on the back of the control panel 2 allows the control panel 2 to be easily fixed in the mounting port 13, and also facilitates disassembly for maintenance or replacement.
