[0037] Reference below Figure 1-Figure 9 A heat exchange plate 100 according to an embodiment of the first aspect of the present invention is described.

[0038] like Figure 1-Figure 9 As shown, the heat exchange plate 100 according to the first embodiment of the present invention includes a body 1.

[0039] Specifically, a plurality of first liquid ports 11 are formed on the body 1, and a plurality of first protrusions 12 are provided on the periphery of each first liquid port 11. The plurality of first protrusions 12 are spaced apart along the circumference of the first liquid port 11, and each first protrusion 12 is configured to make the fluid flowing through the first protrusion 12 flow along the edge toward the heat exchange plate 100. In the description of the present invention, "plurality" means two or more.

[0040] For example, in Figure 1 and Figure 4 In the example, four first liquid ports 11 are formed at intervals on the main body 1, and thirteen first protrusions 12 are provided at intervals in the circumferential direction of each first liquid port 11. Each first protrusion 12 guides the fluid flowing through the first protrusion 12, so that the fluid flows toward the edge of the heat exchange plate 100, so as to increase the flow rate of the fluid and improve the heat exchange efficiency of the heat exchange plate 100.

[0041] When the first liquid port 11 is a liquid inlet, the fluid flowing out of the first liquid port 11 is blocked by the multiple first protrusions 12, so that the fluid is divided into multiple streams and flows in a direction away from the first liquid port 11, which is beneficial for the fluid to cover the entire body 1, further increasing the heat exchange path of the fluid, and further improving the heat exchange efficiency of the heat exchange plate 100; when the first liquid port 11 is a liquid outlet, the fluid flowing to the first liquid port 11 flows along the extension direction of the first protrusion 12 to the first liquid port 11, thereby increasing the flow speed of the fluid near the first liquid port 11, so as to improve the heat exchange efficiency of the heat exchange plate 100.

[0042] According to the heat exchange plate 100 of the embodiment of the present invention, a plurality of first protrusions 12 are provided on the periphery of each first liquid port 11 so as to utilize the first protrusions 12 to guide the fluid, so that the fluid flowing through the first protrusions 12 flows along the edge of the heat exchange plate 100, thereby increasing the flow of the fluid, facilitating the fluid to cover the entire heat exchange plate 100, and improving the heat exchange efficiency of the heat exchange plate 100.

[0043] According to some embodiments of the present invention, referring to Figure 1 and Figure 4 The heat exchange plate 100 further includes a plurality of protrusion groups 2, which are arranged in a first direction of the body 1 (for example, Figure 4 In the up-down direction), at least one side of the plurality of protrusion groups 2 is disposed along a second direction (for example, Figure 1 In the up and down direction), each protrusion group 2 includes a plurality of protrusions along the third direction (for example, Figure 1 The first direction, the second direction and the third direction are orthogonal to each other.

[0044] For example, a plurality of second protrusions 21 (such as Figure 1 and Figure 4As shown in FIG. 1 , the second protrusion 21 is used to disturb the fluid flowing on the side of the body 1, so that the fluid can fully flow on the side of the body 1. As a result, the temperature difference at different positions of the heat exchange plate 100 is reduced, and the heat exchange balance of the heat exchange plate 100 is improved. At the same time, the outer peripheral surface of the second protrusion 21 can guide the fluid flowing through the second protrusion 21, thereby extending the heat exchange path of the fluid, increasing the residence time of the fluid, and greatly improving the heat exchange efficiency of the heat exchange plate 100.

[0045] By forming a plurality of second protrusions 21 into a plurality of protrusion groups 2 spaced apart along the second direction, the regularity of the arrangement of the second protrusions 21 on the body 1 is increased, so that the fluid can flow along a prescribed heat exchange path. In addition, the second protrusions 21 in each protrusion group 2 can be designed differently to meet the turbulence requirements at different positions of the body 1.

[0046] Further, refer to Figure 1 , the extension direction of each second protrusion 21 forms an angle with the central axis of the body 1 in the third direction. That is to say, the second protrusion 21 can be inclined toward any end of the second direction away from the central axis of the body 1 in the third direction, and the fluid flows along the inclined direction of the second protrusion 21, so that the fluid can be evenly distributed, and the residence time of the fluid can also be increased, thereby improving the heat exchange efficiency of the heat exchange plate 100.

[0047] Furthermore, refer to Figure 1 , along the second direction, the two side walls of the body 1 away from the center of the body 1 are respectively the first side wall 13 and the second side wall 14. The plurality of protrusion groups 2 include a plurality of first protrusion groups 22 and a plurality of second protrusion groups 23, the plurality of first protrusion groups 22 and the plurality of second protrusion groups 23 are staggered along the second direction, the second protrusion 21 of each first protrusion group 22 extends obliquely from the center axis of the body 1 in the third direction to the second side wall 14, and the second protrusion 21 of each second protrusion group 23 extends obliquely from the center axis of the body 1 in the third direction to the first side wall 13.

[0048] like Figure 1As shown, eight first protrusion groups 22 and seven second protrusion groups 23 are provided on the body 1, and the eight first protrusion groups 22 and the seven second protrusion groups 23 are arranged alternately along the second direction. The first protrusion group 22 and the second protrusion group 23 both guide the fluid, and at this time, the second protrusion 21 of the first protrusion group 22 makes the fluid flow along the central axis of the body 1 in the third direction to the second side wall 14, that is, the fluid diffuses from the center to the edge of the body 1, and avoids the fluid flowing only along the central axis of the body 1 in the third direction, and the second protrusion 21 in the second protrusion group 23 makes the fluid flow along the central axis of the body 1 in the third direction to the first side wall 13, that is, the fluid diffuses from the edge to the center of the body 1. Since the first protrusion group 22 and the second protrusion group 23 are arranged in an alternating manner, the fluid flows along the direction from the central axis of the main body 1 in the third direction to the second side wall 14, and then flows along the direction from the central axis of the main body 1 in the third direction to the second side wall 14, and circulates multiple times, so that the flow path of the fluid is wavy, thereby enhancing the turbulence effect on the main body 1, thereby increasing the heat exchange amount of the fluid, and further improving the heat exchange efficiency of the heat exchange plate 100.

[0049] In addition, refer to Figure 1 and Figure 4 The multiple second protrusions 21 of each first protrusion group 22 are symmetrical about the central axis of the body 1 in the third direction. The multiple second protrusions 21 of each protrusion group 2 are evenly distributed on both sides of the central axis of the body 1 in the third direction, so that the fluid is evenly distributed on both sides of the central axis of the body 1 in the third direction, thereby improving the uniformity of the fluid distribution and increasing the reliability of the heat exchange plate 100.

[0050] Optionally, the plurality of second protrusions 21 of each second protrusion group 23 are also symmetrical about the central axis of the body 1 in the third direction.

[0051] Further, refer to Figure 1 and Figure 4 , the two outermost second protrusions 21 in each first protrusion group 22 in the third direction are spaced apart from the edge of the body 1. The two outermost second protrusions 21 in each second protrusion group 23 in the third direction are connected to the edge of the body 1. That is, in the third direction, the second protrusion 21 of the first protrusion group 22 is located between two adjacent second protrusions 21 of the second protrusion group 23. Thus, the fluid is disturbed and guided in an alternating manner, so that the heat exchange plate 100 has a higher heat exchange efficiency.

[0052] Furthermore, refer to Figure 1 and Figure 4, the minimum distance between each first protrusion group 22 and the edge of the body 1 in the third direction is L1, the minimum distance between each first protrusion group 22 and the central axis of the body 1 in the third direction is L2, and the minimum distance between two adjacent second protrusions 21 of each protrusion group 2 in the third direction is L3, wherein L1, L2 and L3 satisfy: L1=L2≤L3. In this way, the minimum distance between each first protrusion group 22 and the edge of the body 1 in the third direction and the minimum distance between each first protrusion group 22 and the central axis of the body 1 in the third direction are both small, and the minimum distance between two adjacent second protrusions 21 of each protrusion group 2 is large, thereby reducing the fluid flow between the second protrusion 21 and the edge of the body 1 and the central axis of the body 1 in the third direction, so that more fluid flows evenly in the first protrusion group 22, increasing the turbulence effect of the body 1, and thus increasing the heat exchange capacity.

[0053] According to some embodiments of the present invention, referring to Figure 1 , the angle between the second protrusion 21 and the central axis of the body 1 in the third direction is ɑ, where ɑ satisfies: 0°<ɑ≤45°. When ɑ>45°, the angle between the second protrusion 21 and the central axis of the body 1 in the third direction is large, so that the fluid is gathered at the edge of the body 1 or on both sides of the central axis of the body 1 in the third direction after being guided by the second protrusion 21, resulting in a smaller amount of fluid in the protrusion group 2 area, thereby reducing the heat exchange efficiency. Therefore, by setting the angle between the second protrusion 21 and the central axis of the body 1 in the third direction to 0°<ɑ<45°, the fluid can be evenly distributed in the protrusion group 2 area after being guided by the second protrusion 21, thereby improving the heat exchange efficiency of the heat exchange plate 100.

[0054] Optionally, refer to Figure 1 and Figure 2, the shape of the second protrusion 21 is elliptical, the length of the major axis of the second protrusion 21 is L4, and the length of the minor axis of the second protrusion 21 is L5, wherein L4 and L5 satisfy: 1<L4 / L5<3. When L4 / L5<1, the ratio of the length of the major axis of the second protrusion 21 to the length of the minor axis is small, that is, the length of the major axis of the second protrusion 21 is small, the length of the minor axis of the second protrusion 21 is large, the shape of the cross section of the second protrusion 21 tends to be circular, and the flow guiding effect on the fluid is poor; when L4 / L5>3, the ratio of the length of the major axis of the second protrusion 21 to the length of the minor axis is large, that is, the length of the major axis of the second protrusion 21 is large, and the length of the minor axis of the second protrusion 21 is short. Within the limited size of the body 1, the number of protrusion groups 2 will be reduced, thereby reducing the number of changes in the flow direction of the fluid, and the turbulence effect is poor, resulting in poor heat exchange effect of the heat exchange plate 100. Therefore, by setting the ratio of the length of the major axis to the length of the minor axis of the second protrusion 21 to 1<L4 / L5<3, the design of the length of the major axis and the length of the minor axis of the second protrusion 21 is more reasonable, which not only improves the guiding effect of the second protrusion 21 on the fluid, but also helps to increase the turbulence effect, thereby improving the heat exchange efficiency of the heat exchange plate 100.

[0055] According to some embodiments of the present invention, referring to Figure 3 , the shape of the second protrusion 21 is prismatic, and the acute angle of the second protrusion 21 is β, wherein β satisfies: 30°<β<80°. When β<30°, the acute angle of the second protrusion 21 is small, the length of the major axis of the second protrusion 21 is long, and the length of the minor axis is short, so that the shape of the cross section of the second protrusion 21 tends to be long strip, which will reduce the turbulence effect of the second protrusion 21, thereby reducing the heat exchange; when β>80°, the acute angle of the second protrusion 21 is large, the length of the major axis of the second protrusion 21 is small, and the length of the minor axis is long, so that the shape of the cross section of the second protrusion 21 tends to be rectangular, which increases the flow resistance of the fluid, reduces the flow velocity of the fluid, and reduces the heat exchange efficiency of the fluid. Therefore, by setting the acute angle of the second protrusion 21 to 30°<β<80°, the length of the major axis and the length of the minor axis of the second protrusion 21 are designed more reasonably, which improves the turbulence effect of the second protrusion 21 on the fluid, while helping to reduce the flow resistance of the fluid, thereby improving the heat exchange efficiency.

[0056] The heat exchanger 200 according to the second embodiment of the present invention is characterized in that it includes: a plurality of first heat exchange plates 201 and at least one second heat exchange plate 100. The plurality of first heat exchange plates 201 are arranged along the first direction, and a plurality of second liquid ports 202 are formed on each first heat exchange plate 201. The second heat exchange plate 100 is arranged between two adjacent first heat exchange plates 201, and the plurality of first liquid ports 11 of the second heat exchange plate 100 correspond to the plurality of second liquid ports 202 one by one. The second heat exchange plate 100 and the two adjacent first heat exchange plates 201 define a first flow channel 203 and a second flow channel 204 respectively. The second heat exchange plate 100 is the heat exchange plate 100 of the first embodiment of the present invention. The first flow channel 203 and the second flow channel 204 are suitable for flowing different cooling media, part of the first liquid ports 11 and part of the second liquid ports 202 are connected to the second flow channel 204, and the remaining first liquid ports 11 and the remaining second liquid ports 202 are connected to the first flow channel 203.

[0057] For example, in Figure 4-Figure 6 In the example, the heat exchanger 200 includes at least two first heat exchange plates 201 and one second heat exchange plate 100, and the two adjacent first heat exchange plates 201 are respectively arranged on both sides of the second heat exchange plate 100 in the thickness direction (i.e., the first direction). One of the two adjacent first heat exchange plates 201 and one side surface of the second heat exchange plate 100 in the thickness direction jointly define a first flow channel 203, and the other of the two adjacent first heat exchange plates 201 and the other side of the second heat exchange plate 100 in the thickness direction jointly define a second flow channel 204, and the first flow channel 203 and the second flow channel 204 are not connected to each other, and different cooling media can flow in the first flow channel 203 and the second flow channel 204, for example, a refrigerant liquid flows in one of the first flow channel 203 and the second flow channel 204, and a cooling liquid flows in the other of the first flow channel 203 and the second flow channel 204, and the temperatures of different cooling media are different to achieve heat exchange.

[0058] Four second liquid ports 202 are formed at intervals on the first heat exchange plate 201, and four first liquid ports 11 are formed at intervals on the second heat exchange plate 100, and the four second liquid ports 202 correspond to the four first liquid ports 11 one by one. Two second liquid ports 202 and the corresponding two first liquid ports 11 are used to connect the first flow channel 203, and the remaining two second liquid ports 202 and the corresponding two first liquid ports 11 are used to connect the second flow channel 204, so that two fluids of different temperatures flow in the corresponding first flow channel 203 or the second flow channel 204 and exchange heat. In addition, the liquid inlet and liquid outlet corresponding to the first flow channel 203 are interchangeable, and the liquid inlet and liquid outlet corresponding to the second flow channel 204 are also interchangeable, that is, any one of the two second liquid ports 202 connected to the corresponding flow channel can be a liquid inlet, and the other can be a liquid outlet, and it does not affect the use of the heat exchanger 200, thereby improving the applicability of the heat exchanger 200.

[0059] According to the heat exchanger 200 of the embodiment of the present invention, the second heat exchange plate 100 is disposed between two adjacent first heat exchange plates 201, and the second heat exchange plate 100 and the two adjacent first heat exchange plates 201 respectively define a first flow channel 203 and a second flow channel 204, and different cooling media can flow through the first flow channel 203 and the second flow channel 204. Thus, different cooling media in the first flow channel 203 and the second flow channel 204 achieve heat exchange, thereby achieving heat exchange of the heat exchanger 200.

[0060] Further, refer to Figure 6 and Figure 7 , the maximum depth of the first flow channel 203 in the first direction is H1, and the minimum depth of the second flow channel 204 in the first direction is H2, wherein H1 and H2 satisfy: H1<H2. Thus, the size of the first flow channel 203 is small, and the size of the second flow channel 204 is large. In actual use, the refrigerant liquid can be passed into the first flow channel 203 with a smaller size, and the cooling liquid can be passed into the second flow channel 204 with a larger size, so that the smaller volume of the refrigerant liquid and the larger volume of the cooling liquid can exchange heat.

[0061] In addition, refer to Figure 4 and Fig. 9 The heat exchanger 200 further includes at least one spoiler 205, which is disposed in the second flow channel 204. A plurality of first through holes 2051 are formed on the spoiler 205, and the first through holes 2051 correspond to the second liquid port 202, so as to avoid interference between the spoiler 205 and the second liquid port 202 when the spoiler 205 is disposed in the second flow channel 204, thereby improving the installation stability of the spoiler 205 in the second flow channel 204. Thus, the spoiler 205 can be used to turbulent the fluid in the second flow channel 204, so as to increase the heat exchange efficiency of the heat exchanger 200.

[0062] According to some embodiments of the present invention, referring to Figure 4The heat exchanger 200 further includes a top plate 206, a bottom plate 207, a mounting bracket 208 and a plurality of pipe joints 209. Along the first direction, the top plate 206 and the bottom plate 207 respectively abut against the two outermost first heat exchange plates 201. The mounting bracket 208 is disposed on the side of the top plate 206 away from the first heat exchange plate 201. The plurality of pipe joints 209 correspond one-to-one to the plurality of first liquid ports 11, one end of each pipe joint 209 passes through the mounting bracket 208 and the top plate 206 to communicate with the first liquid port 11, and the other end of each pipe joint 209 is suitable for connection with an external pipeline. The top plate 206 and the bottom plate 207 abut against the two outermost first heat exchange plates 201 along the first direction to clamp the first heat exchange plate 201 and the second heat exchange plate 100, and the bottom plate 207 blocks the second liquid port 202 on the corresponding first heat exchange plate 201. The plurality of first liquid ports 11 on the top plate 206 correspond to the plurality of pipe joints 209, which are connected to the surrounding pipes to introduce or export fluids in the first flow channel 203 and the second flow channel 204. A plurality of second through holes 2081 are formed on the mounting bracket 208 to facilitate cooperation with surrounding devices to fix the heat exchanger 200.
