On the other hand, when the heat exchange area is the same, the cross-sectional area of ​​the channel can be reduced, thereby reducing the overall volume of the heat exchange component.

[0049] See also Figures 1 to 11, further, in this embodiment, the heat exchange assembly includes two first heat exchange plates 1, a second heat exchange plate 2 and a sealing structure 3, the second heat exchange plate 2 is sandwiched between the two first heat exchange plates 1 to form two layers of first flow channels and a layer of second flow channels, the layer of second flow channels is sandwiched between the two layers of first flow channels, and each layer of first flow channels is provided with a plurality of first heat exchange flow channels 6, and each layer of second flow channels is provided with a plurality of second heat exchange flow channels 7. Specifically, the sealing structure 3 is provided with a plurality of first flanges 15 extending from the peripheral edge of the first heat exchange plate 1, and a second flange extending from the peripheral edge of the second heat exchange plate 2.

Importantly, the first heat exchange plate 1 is provided with four The first through hole 14 is provided in the second heat exchange plate 2, and the second through holes 24 are corresponding to the four first through holes 14 in a one-to-one manner. A sealing structure 3 is provided between the first heat exchange plate 1 and the second heat exchange plate 2. The sealing structure 3 is hollow in the middle so that a chamber is formed between the first heat exchange plate 1 and the second heat exchange plate 2, and the sealing structure 3 is provided with a first semicircular through hole 34, a first circular through hole 32, a second semicircular through hole 35 and a first circular sealing gasket 33 surrounding the periphery of the chamber and corresponding to the four first through holes 14 or the four second through holes 24 in a one-to-one manner.

On the other hand, the modularization of the heat exchange component is realized, the number of component types is reduced, the assembly is facilitated, and the production cost is reduced.

[0050] See also Figures 10 to 12 Furthermore, the first heat exchange plate 1 and the second heat exchange plate 2 are both rectangular, and the plurality of first guide ribs 11 and the plurality of second guide ribs 21 are correspondingly arranged and distributed in sequence.

[0052] One end of the second guide rib 21 is against the sealing structure 3, and the other end is separated from the sealing structure 3, and the directions of the ends of the two adjacent second guide ribs 21 against the sealing structure 3 are opposite; such an arrangement enables the two adjacent first heat exchange channels 6, the two adjacent second heat exchange channels 7, the two adjacent third heat exchange channels 8, and the two adjacent fourth heat exchange channels 9 to form S-shaped channels, so that the liquid needs to flow through multiple channels in sequence, and the liquid can flow normally and be evenly distributed between the channels of each layer, thereby achieving an improvement in heat exchange efficiency.

[0053] It should be noted that the above-mentioned technical solutions for assembling the first guide rib 11 and the sealing structure 3 and the technical solutions for assembling the second guide rib 21 and the sealing structure 3 can be used alone or in combination.

[0054] It can be understood that in other preferred embodiments, the number of first heat exchange plates 1 can be set to N (N is greater than or equal to 2), and the number of second heat exchange plates 2 can be set to N or N+1.

[0055] like Figure 8 and Figure 9 As shown, preferably, the first and third cross-sections are trapezoidal, and the second and fourth cross-sections are inverted trapezoidal. Utilizing the trapezoidal and inverted trapezoidal shapes, adjacent first and second heat exchange plates 1 and 2 are in surface contact, and each first heat exchange channel 6 and each second heat exchange channel 7 has eight heat exchange surfaces. This means that with the same channel cross-sectional area, the heat exchange area can be further increased, thereby achieving a more optimal heat exchange effect. Preferably, the height of the first and third cross-sections, as well as the depth of the second and fourth cross-sections, are all within the range of 1.5 mm to 5 mm to ensure that the liquid pressure is within a reasonable range, extend the service life, and enable normal liquid flow.

[0056] See also Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 14 、 Figure 15 、 Figure 16 、 Figure 17Furthermore, a plurality of reinforcing ribs 45 are protruding from the outer surface of the front cover 4 to prevent the front cover 4 from deforming when the heat exchange device exchanges heat with the liquid.

[0057] See also Figure 1 、 Figure 10 and Figure 11 Preferably, a first positioning protrusion 16 is provided around the first through hole 14, and a second positioning protrusion 26 is provided around the second through hole 24. Each sealing structure 3 is provided with a positioning hole 31 corresponding to the first positioning protrusion 16 and the second positioning protrusion 26 to position the sealing structure 3, thereby ensuring the sealing effect.

[0058] See also Figures 14 to 17 Importantly, the front cover 4 is provided with a first through hole column 41 and a second through hole column 42 for the inlet and outlet of liquid, and the rear cover 5 is provided with a third through hole column 51 and a fourth through hole column 52 for the inlet and outlet of liquid.

[0059] See also Figure 10 、 Figure 14 、 Figure 15 、 Figure 16 and Figure 17 As a preferred embodiment, the first through-hole column 41 is the high-temperature liquid inlet, the second through-hole column 42 is the low-temperature liquid inlet, the third through-hole column 51 is the high-temperature liquid outlet, and the fourth through-hole column 52 is the low-temperature liquid outlet to form downstream heat exchange.

[0060] See also Figure 11 、 Figure 14 、 Figure 15 、 Figure 16 and Figure 17 As a preferred embodiment, the first through-hole column 41 is the high-temperature liquid inlet, the second through-hole column 42 is the low-temperature liquid outlet, the third through-hole column 51 is the high-temperature liquid outlet, and the fourth through-hole column 52 is the low-temperature liquid inlet to form countercurrent heat exchange.

[0061] Example 2

[0062] See also Figures 18 to 20The only difference between this embodiment and the first embodiment is that the specific shapes of the first guide rib 11 and the second guide rib 21 are different.

[0063] Specifically, in this embodiment, the plurality of first guide ribs 11 and the plurality of second guide ribs 21 are all in a herringbone shape and are arranged in sequence accordingly to form a V-shaped flow channel to increase the flow rate of the liquid and thus improve the heat exchange effect.

[0064] Importantly, both ends of one of the two adjacent first guide ribs 11 are against the sealing structure 3, and a first drain groove 13 is provided in the middle, and both ends of the other of the two adjacent first guide ribs 11 are separated from the sealing structure 3;

[0065] Both ends of one of the two adjacent second guide ribs 21 abut against the sealing structure 3, and a second drain groove 23 is provided in the middle. Both ends of the other two adjacent second guide ribs 21 are separated from the sealing structure 3. This arrangement allows the heat exchange liquid to flow from the middle end to the two ends of one of the two adjacent V-shaped flow channels, and then flow from the two ends to the middle end of the other of the two adjacent V-shaped flow channels. As a result, the liquid needs to flow through multiple flow channels in sequence and can circulate normally and be evenly distributed between the flow channels of each layer, thereby improving the heat exchange efficiency.

[0066] It should be noted that the above-mentioned arrangement scheme of the first drain trough 13 and the arrangement scheme of the second drain trough 23 can be used alone or in combination.

[0067] Example 3

[0068] See also Figures 21 to 23 The difference between this embodiment and the first embodiment lies in the difference in the shapes of the first heat exchange plate 1 and the second heat exchange plate 2, and the difference in the specific arrangement of the first guide ribs 11 and the second guide ribs 21.

[0069] Specifically, in this embodiment, the first heat exchange plate 1 and the second heat exchange plate 2 are circular, and the first guide ribs 11 and the second guide ribs 21 are correspondingly distributed in a circular radial pattern.

[0070] Each annular first guide rib 11 has four arc segments, with a first drain trough 13 formed between adjacent arc segments; each annular second guide rib 21 has four arc segments, with a second drain trough 23 formed between adjacent arc segments. This allows for normal flow and even distribution of liquid between two adjacent first heat exchange channels 6, between two adjacent second heat exchange channels 7, between two adjacent third heat exchange channels 8, and between two adjacent fourth heat exchange channels 9. Furthermore, the surface area of ​​the first and second heat exchange plates 1 and 2 is fully utilized to increase the number of first and second guide ribs 11 and 21, thereby improving heat exchange efficiency.

[0071] It should be noted that the above-mentioned arrangement scheme of the first drain trough 13 and the arrangement scheme of the second drain trough 23 can be used alone or in combination.

[0072] It can be understood that the number of arc segments of each annular first guide rib 11 can be 1, 2, 3, 5, 6, etc., and the number of arc segments of each annular second guide rib 21 can be 1, 2, 3, 5, 6, etc., and when the number of arc segments of the first guide rib 11 is 1, the arc segment is not closed and its opening forms a first drainage trough 13; when the number of arc segments of the second guide rib 21 is 1, the arc segment is not closed and its opening forms a second drainage trough 23.

[0073] The technical means disclosed in the solutions of the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
