The first heat exchange channel 111 can be a channel for high-temperature liquid, and the second heat exchange channel 151 can be a channel for low-temperature liquid; or the first heat exchange flow channel 111 may be a flow channel of a low temperature liquid, and the second heat exchange flow channel 151 may be a flow channel of a high temperature liquid, so that the liquid in the first heat exchange flow channel 111 and the liquid in the second heat exchange flow channel 151 may exchange heat through the heat conducting plate 18.

Each heat conducting plate 18 has a first heat conducting surface 181 and a second heat conducting surface 183, the first heat conducting surface 181 and the second heat conducting surface 183 are located on two opposite sides of the heat conducting plate 18, the first flow channel assembly 11 is attached to the first heat conducting surface 181, and the second flow channel assembly 15 is attached to the second heat conducting surface 183. Wherein the heat-conducting plate 18 may be a material having heat-conducting properties, for example, the heat-conducting plate 18 may be a metal plate material.

The heat transfer plate 18 is provided with a first water passing hole 185 and a second water passing hole 187 penetrating the first heat transfer surface 181 and the second heat transfer surface 183. Wherein, at least one first flow channel assembly 11 and at least one second flow channel assembly 15 are alternately arranged, a heat conducting plate 18 is disposed between the adjacent first flow channel assembly 11 and second flow channel assembly 15, and the first heat exchanging flow channel 111 is communicated with the first water passing hole 185, and the second heat exchanging flow channel 151 is communicated with the second water passing hole 187. In this manner, the first heat exchange flow channel 111 and the second heat exchange flow channel 151 may be separated from each other and exchange heat through the heat conductive plate 18. In addition, the number of the first flow channel assembly 11, the second flow channel assembly 15 and the heat conducting plate 18 can be increased or decreased according to the requirement, so that different heat exchange effects can be set for the heat exchanger 10, and different application conditions and scenes can be met.

When the temperature of the liquid is required to be low, the number of the first flow channel member 11 and the heat conductive plate 18 can be increased; when a higher temperature of the liquid is required, the number of second flow channel assemblies 15 and heat conductive plates 18 can be increased; when the heat exchange efficiency is required to be high, the number of the first flow channel assembly 11, the second flow channel assembly 15 and the heat conductive plate 18 may be increased at the same time.

For example, the number of the first flow channel assembly 11, the second flow channel assembly 15, and the heat conductive plate 18 may be one, and the low temperature flow channel-the heat conductive plate 18-the high temperature flow channel may be arranged in this order. Alternatively, the high-temperature flow channel, the heat-conducting plate 18 and the low-temperature flow channel can be arranged in sequence.

For another example, the number of the first flow channel assembly 11 and the heat conductive plate 18 may be two, and the number of the second flow channel assembly 15 may be one, and the low temperature flow channel-the heat conductive plate 18-the high temperature flow channel-the heat conductive plate 18-the low temperature flow channel may be arranged in this order.

For another example, the number of the first flow channel assembly 11 and the second flow channel assembly 15 may be two, and the number of the heat conducting plates 18 may be three, so that the flow channels and the heat conducting plates 18 may be arranged in the order of the low temperature flow channel-heat conducting plate 18-high temperature flow channel-heat conducting plate 18-low temperature flow channel-heat conducting plate 18-high temperature flow channel. Alternatively, the flow channels and the heat conducting plate 18 may be arranged in the order of high temperature flow channel-heat conducting plate 18-low temperature flow channel-heat conducting plate 18-high temperature flow channel-heat conducting plate 18-low temperature flow channel.

According to the above, the number of the first flow channel assembly 11, the second flow channel assembly 15 and the heat conducting plate 18 is at least one, and one heat conducting plate 18 is added every time one first flow channel assembly 11 or one second flow channel assembly 15 is added, so that two spaced low temperature flow channels and two spaced high temperature flow channels can be formed to facilitate heat exchange.

In some embodiments, the first flow channel assembly 11, the second flow channel assembly 15, and the thermally conductive plate 18 may be compressed by a platen. For example, the heat exchanger 10 can further include opposing first and second platens 21, 23, with the first and second flow channel assemblies 11, 15 and the heat conductive plate 18 each being positioned between the first and second platens 21, 23. In this manner, the first and second pressure plates 21, 23 can compress the first flow passage assembly 11, the heat conductive plate 18, and the second flow passage assembly 15, helping to improve the seal of the heat exchanger 10.

The first pressing plate 21 may be provided with a first water inlet 211, a first water outlet 213, a second water inlet 215 and a second water outlet 217, the first water inlet 211 and the first water outlet 213 are respectively communicated with two ends of the first heat exchanging flow channel 111, and the second water inlet 215 and the second water outlet 217 are respectively communicated with two ends of the second heat exchanging flow channel 151. Thus, the low-temperature liquid can sequentially enter the heat exchanger 10 through the first water inlet hole 211 and the first heat exchange flow channel 111 for heat exchange, and the liquid after heat exchange flows out through the first water outlet hole 213; the high-temperature liquid may sequentially enter the heat exchanger 10 through the second water inlet 215 and the second heat exchange flow channel 151 for heat exchange, and the liquid after heat exchange flows out through the second water outlet 217.

When the number of the first heat exchange flow channels 111 and the second heat exchange flow channels 151 is multiple, the first heat exchange flow channels 111 can be communicated by providing water through holes in the first flow channel assembly 11 and the second flow channel assembly 15, so that the low-temperature liquid can flow in the first heat exchange flow channels 111 and exchange heat; and, the plurality of second heat exchange flow channels 151 may be communicated, so that the high temperature liquid may flow in the plurality of second heat exchange flow channels 151 and exchange heat

As such, the high temperature liquid may pass through the first flow channel assembly 11 through the third water passing hole 131 and pass through the heat conductive plate 18 through the second water passing hole 187 to enter the second heat exchanging flow channel 151, so that the plurality of second heat exchanging flow channels 151 may be communicated, and also so that the second heat exchanging flow channel 151 and the first heat exchanging flow channel 111 may be spaced apart.

Referring to fig. 2, 4 and 5, the second flow channel assembly 15 may include a second flow guiding element 150 and a second annular sealing element 170, the second flow guiding element 150 is connected to the second annular sealing element 170 and is located within a ring of the second annular sealing element 170, the second flow guiding element 150 is provided with a second heat exchanging flow channel 151, and the second annular sealing element 170 is provided with a fourth water passing hole 171. The second annular seal 170 helps to prevent liquid in the second heat exchange channel 151 from leaking out, improving the sealing of the heat exchanger 10.

Thus, the low temperature liquid may pass through the second flow channel assembly 15 from the fourth water passing hole 171, and pass through the heat conducting plate 18 through a water passing hole to enter the first heat exchanging flow channel 111, so that the plurality of first heat exchanging flow channels 111 may be communicated, and the first heat exchanging flow channel 111 and the second heat exchanging flow channel 151 may be spaced apart.
