DETAILED DESCRIPTION
[0021] The technical scheme in the embodiments of the present utility model will be described clearly and completely in combination with the drawings in the embodiments of the present utility model, obviously, the described embodiments are only some embodiments of the present utility model, not all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present utility model.
[0022] Please refer to Figures 1-4The utility model provides an embodiment: a kind of air cooler with water leakage protection function, including box 1, the front and rear sides of box 1 are provided with connecting port 2, the inside of box 1 is provided with heat exchange subassembly 3, heat exchange subassembly 3 includes fixed frame 31, plate-fin heat exchanger 32, water outlet 33 and water inlet 34, two groups of fixed frame 31 are fixedly installed in the inside of box 1, plate-fin heat exchanger 32 is installed in the inside of fixed frame 31, the right side of plate-fin heat exchanger 32 is fixedly connected with water outlet 33, the right side of plate-fin heat exchanger 32 is fixedly connected with water inlet 34 at the bottom of water outlet 33, the bottom of fixed frame 31 is provided with anti-leakage component 4;First, water is input through the water inlet 34 of two plate-fin heat exchangers 32, and cooling air is input into the box 1 from the two connecting ports 2 respectively, then the air passes through the plate-fin heat exchanger 32, and the air is gathered into the cavity between the two plate-fin heat exchangers 32 after heat exchange by the plate-fin heat exchanger 32, and finally discharged from the bottom, and the water after heat exchange is discharged from the water outlet 33;
[0023] The device solves the problem of water leakage in the air cooler, and the water accumulates in the cooler cavity, which cannot be discharged. When the water volume is large, it will flow into the generator, causing internal insulation to decrease and causing the generator to be damaged.
[0024] Further, the anti-leakage component 4 includes a water storage tank 41, a float level switch 42, and a stainless steel float ball 43. The bottom of the fixed frame 31 is directly below the plate-fin heat exchanger 32 and is clamped with the water storage tank 41. The cross section of the water storage tank 41 is triangular. The float level switch 42 is installed in the water storage tank 41. The inner wall of the water storage tank 41 is fixedly installed with the stainless steel float ball 43. Figure 4 As shown in the figure, the structure is used to connect the float level switch 42 to the external circuit by wires. The water leaked from the plate-fin heat exchanger 32 flows into the water storage tank 41. The stainless steel float ball 43 in the float level switch 42 floats with the rising water level in the water storage tank 41. The magnet in the stainless steel float ball 43 acts on the magnetic reed switch inside the water storage tank 41 to close the magnetic reed switch, thereby conducting the external circuit and transmitting a signal to the user to remind the staff of the water leakage.
[0025] Further, the inside of the box 1 is fixedly installed with a temperature sensor 5. The front and rear of the box 1 are fixedly connected with two groups of grounding holes 6, which ensures the stable grounding of the internal circuit, protects the safety of the circuit and equipment, and also plays an important role in cost control and interference prevention. Figure 4 As shown in the figure, the structure is used to monitor the temperature inside the box 1 in real time by the temperature sensor 5 to avoid the internal temperature of the box 1 exceeding the specified range.
[0026] Furthermore, inside the housing 1, a guide plate 7 is fixedly connected between the two sets of plate-fin heat exchangers 32, and the wide side of the guide plate 7 has a rounded corner design. Figure 4 As shown, this structure is used to guide the airflow into the housing 1 through the guide plate 7, generating vortices. The vortices flow towards the plate-fin heat exchanger 32, increasing the air intake and thus improving the heat exchange efficiency.
[0027] Furthermore, automatic exhaust valves 9 are fixedly connected to the top left side of each of the two sets of mounting brackets 31. For example... Figure 2 As shown, this structure is used to discharge gas from the plate-fin heat exchanger 32 through the automatic exhaust valve 9, ensuring internal pressure balance.
[0028] Furthermore, four sets of lifting rings 8 are fixedly connected to the four corners of the top of the box 1, and four sets of connecting plates 10 are fixedly connected to the bottom edge of the box 1. Figure 4 As shown, this structure is used to facilitate the transportation of the box 1 via four sets of lifting rings 8, and to facilitate the installation and fixing of the box 1 via the connecting plate 10 at the bottom.
[0029] Furthermore, a drain outlet 44 is provided on the surface of the tank 1. The drain outlet 44 is located on the outside of the water storage tank 41 and is connected to the inside of the water storage tank 41. Figure 3 As shown, this structure is used to discharge water from the drain outlet 44 when the water in the water tank 41 continues to rise, through the action of the float level switch 42 and the stainless steel float 43.
[0030] Working principle: When using, such as Figure 1 and Figure 2 As shown, water first enters through the inlets 34 of the two plate-fin heat exchangers 32, while cooling air is simultaneously introduced into the housing 1 from the two connection ports 2. The air then passes through the plate-fin heat exchangers 32, and after heat exchange, the air converges into the cavity between the two plate-fin heat exchangers 32. Finally, it is discharged from the bottom through the guide plate 7, while the water that has undergone heat exchange is discharged through the outlet 33. Figure 3 and Figure 4 As shown, the float level switch 42 is connected to an external circuit via a wire. Water leaking from the plate-fin heat exchanger 32 flows into the water storage tank 41. The stainless steel float 43 in the float level switch 42 floats up as the water level in the water storage tank 41 rises. The magnet inside the stainless steel float 43 acts on the reed switch inside the water storage tank 41, causing the reed switch to close, thereby connecting the external circuit and transmitting a signal to the user to remind the staff of the leak. As the water in the water storage tank 41 continues to rise, the water is discharged from the drain outlet 44. The above is the complete working principle of this utility model.
[0031] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
