Multiple fixing screws 9 are threadedly connected to each fixing seat 8, with six fixing screws 9 in each fixing seat 8. A connecting assembly 2 is provided on the heat exchanger body 1. The connecting assembly 2 includes multiple connecting pipes 201 fixedly disposed on the heat exchanger body 1, with four connecting pipes 201 in total. Two connecting pipes 201 are input ends, and two connecting pipes 201 are output ends. A connecting cylinder 202 is fixed to one end of two of the connecting pipes 201. A control valve 203 is provided at one end of the connecting cylinder 202 and one end of the other two connecting pipes 201. A connecting joint 204 is internally threaded to one end of the control valve 203. A conveying pipe 205 is provided at one end of the connecting joint 204 for connecting to equipment requiring heat exchange (not shown in the figure).

[0029] A detection assembly 3 is installed on the heat exchanger body 1. The detection assembly 3 includes two pressure sensors 301 installed on the heat exchanger body 1, two liquid level sensors 302 installed on the inner wall of the heat exchanger body 1, and an alarm 303 installed on the upper surface of the heat exchanger body 1. The alarm 303 is electrically connected to four alarm lights 304, which are connected to the connecting pipe 201.

[0030] The alarm light 304, alarm 303, connector 204, liquid level sensor 302, and pressure sensor 301 are existing technologies and therefore are not described or drawn in detail. In actual use, the alarm light 304, alarm 303, liquid level sensor 302, pressure sensor 301, and control valve 203 are electrically connected to a controller. The controller, alarm light 304, alarm 303, liquid level sensor 302, pressure sensor 301, and control valve 203 are electrically connected to an external power supply.

[0031] Example 2:

[0032] like Figures 1-6 As shown, a heat exchanger with leakage detection and alarm function according to an embodiment of the present utility model includes a filter assembly 4 disposed on the inner wall of the connecting assembly 2. The filter assembly 4 includes a plurality of filter ports opened on the connecting assembly 2. The filter ports are opened on the connecting cylinder 202. A filter frame 401 is installed on the inner wall of the filter port. A limiting cover 402 is fixedly connected to one side of the filter frame 401. A filter screen plate 403 and an activated carbon plate 404 are disposed on the inner wall of the filter frame 401. A limiting seat 405 is connected to one end of the filter frame 401. One side of the limiting seat 405 is fixedly connected to the inner wall of the connecting assembly 2. The inner wall of the connecting cylinder 202 is fixedly connected to the limiting seat 405.

[0034] In order to facilitate the understanding of the above technical solutions of the present application, the working principle or operation mode of the present application in the actual process will be described in detail.

[0035] As described above, by means of the above technical solutions of the present application, when in use, the fluid is guided into the heat exchanger body 1 through the connecting pipe 201 and the connecting cylinder 202 in the connecting assembly 2. In this process, the control valve 203 adjusts the flow and direction of the fluid to ensure that the fluid can flow correctly into the heat exchanger body 1. When the fluid passes through the connecting assembly 2, it will first pass through the filter assembly 4. The filter screen plate 403 in the filter frame 401 and the activated carbon plate 404 jointly act to remove impurities in the fluid, thereby protecting the heat exchanger body 1 from pollution or blockage. After the fluid enters the heat exchanger body 1, heat exchange occurs here. The heat exchanger body 1 allows efficient heat transfer between two fluids of different temperatures, but at the same time maintains physical isolation of the two fluids to prevent mixing. During the entire operation, the detection assembly 3 continuously monitors the state of the heat exchanger body 1. The air pressure sensor 301 and the liquid level sensor 302 provided on the heat exchanger body 1 measure the pressure change and liquid level height in the heat exchanger body 1, respectively. If abnormal conditions occur, such as pressure drop or abnormal rise in liquid level due to leakage, the air pressure sensor 301 and the liquid level sensor 302 will immediately transmit information to the alarm 303. Once a potential problem is detected, the alarm 303 will be activated, and the warning light 304 will also be turned on to alert the operator. The warning light 304 is distributed on the connecting pipe 201, so that the warning signal can be clearly seen even at a long distance. In order to facilitate regular maintenance, the chip removal opening and the chip removal cover 5 are designed to be openable for easy removal of impurities intercepted by the filter assembly 4. In addition, the sealing gasket 6 and the fixing screws 7 ensure good sealing of the interfaces, reducing the risk of leakage. At the same time, the multiple fixing seats 8 provided on the surface of the heat exchanger body 1 and the fixing screws 9 thereon increase the stability and safety of the entire device after installation, ensuring that it cannot be easily moved or tilted during operation.

[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
