The heat exchanger plates have a first area and a second area that are spaced apart, and a heat exchange area between the first area and the second area. The heat exchanger plates are provided with a first medium inlet hole, a first medium outlet hole, a second medium inlet hole, and a second medium outlet hole that are spaced apart. The first medium inlet hole and the second medium inlet hole are both located in the first area, and the first medium outlet hole and the second medium outlet hole are both located in the second area. The first medium inlet hole and the first medium outlet hole are arranged opposite to each other, and the second medium inlet hole and the second medium outlet hole are arranged opposite to each other.
[0003] In one part of the heat exchanger plates, the first medium inlet holes and the first medium outlet holes that are relatively distributed are provided with bosses around their outer peripheries. For two adjacent heat exchanger plates, one heat exchanger plate abuts against the other heat exchanger plate located above it through the bosses to form a sealed channel.
[0004] In the prior art, the fins are arranged in the heat exchange area, and the two edges of the fins are respectively close to one side of the two bosses. At this time, the fluid medium entering from the second medium inlet hole is concentrated in the upper half of the heat exchanger plate, that is, the fluid medium can only flow from the second medium inlet hole to the second medium outlet hole in the horizontal direction, and the fluid medium cannot flow in the lower half of the heat exchanger plate, resulting in low heat exchange efficiency of the heat exchanger. Utility Model Content
[0005] The utility model aims to provide a heat exchanger plate and a heat exchanger, which are used to improve the uniformity of fluid medium distribution, so as to improve the heat exchange efficiency of the heat exchanger, thereby improving the heat exchange performance of the heat exchanger.
[0006] In order to achieve the above-mentioned purpose, in the first aspect, the utility model provides a heat exchanger plate. The heat exchanger plate includes: a plate. The plate has a first area and a second area that are spaced apart, and a heat exchange area between the first area and the second area. The plate is provided with a first medium inlet hole, a first medium outlet hole, a second medium inlet hole and a second medium outlet hole that are spaced apart. The first medium inlet hole and the second medium inlet hole are both located in the first area, and the first medium outlet hole and the second medium outlet hole are both located in the second area. The boss is arranged on the plate, and is respectively arranged around the periphery of the first medium inlet hole and the first medium outlet hole. The bosses arranged around the periphery of the first medium inlet hole include a first boss and a second boss close to the heat exchange area, and the first boss is located between the second boss and the second medium inlet hole. For the same position of the heat exchange area, the spacing between the first boss and the heat exchange area is greater than the spacing between the second boss and the heat exchange area.
[0007] Compared with the prior art, in the heat exchanger plate provided by the utility model, since the outer periphery of the first medium inlet and the first medium outlet is provided with a boss, the boss can be used to abut against another heat exchanger plate located above it to form a sealed channel. Further, since the boss arranged around the outer periphery of the first medium inlet includes a first boss and a second boss close to the heat exchange area, the first boss is located between the second boss and the second medium inlet. For the same position of the heat exchange area, the spacing between the first boss and the heat exchange area is greater than the spacing between the second boss and the heat exchange area. At this time, the fluid medium entering the plate from the first medium inlet and the second medium inlet can not only flow laterally in the direction from the second medium inlet to the second medium outlet, so that the fluid medium is distributed in the upper half of the plate heat exchange area. At the same time, the fluid medium can also flow in the direction from the second medium inlet to the first boss, so that the fluid medium enters the flow gap between the first boss and the heat exchange area, and then the fluid medium enters the lower half of the heat exchange area from the above-mentioned flow gap, and then flows out from the second medium outlet. Based on this, compared with the prior art, the area of the fluid medium flow is increased, the uniformity of the fluid medium distribution is improved, thereby improving the heat exchange efficiency of the heat exchanger and improving the heat exchange performance of the heat exchanger. In addition, the heat exchanger plate structure is simple, easy to manufacture, and easy to use, which improves work efficiency.
[0008] In one implementation, the bosses arranged around the first medium outlet hole include a third boss and a fourth boss close to the heat exchange area, and the third boss is located between the fourth boss and the second medium outlet hole. For the same position of the heat exchange area, the distance between the third boss and the heat exchange area is greater than the distance between the fourth boss and the heat exchange area.
[0009] In the case of adopting the above technical solution, combined with the above description, after the fluid medium enters the lower half of the heat exchange area from the circulation gap between the first boss and the heat exchange area, the fluid medium in the lower half of the heat exchange area can not only flow out from the original area between the first medium outlet hole and the second medium outlet hole, but also flow out from the circulation gap between the heat exchange area and the third boss. At this time, not only the flow speed of the fluid medium is accelerated, but also the area of the fluid medium flow is increased, thereby improving the heat exchange efficiency of the heat exchanger and improving the heat exchange performance of the heat exchanger.
[0010] In one implementation, the distance between the outer edge of the first boss and the outer edge of the second boss is greater than or equal to 0.5 mm and less than or equal to 5 mm.
[0011] In the case of adopting the above technical solution, since the distance between the outer edge of the first boss and the outer edge of the second boss is greater than or equal to 0.5 mm, it can be ensured that the size of the flow gap between the first boss and the heat exchange area meets the actual needs, so that the fluid medium entering the plate can flow into the above flow gap. Further, since the distance between the outer edge of the first boss and the outer edge of the second boss is less than or equal to 5 mm, it can be ensured that the area of the heat exchange area meets the actual needs, so as to ensure the heat exchange performance of the heat exchanger formed by the heat exchanger plate. Furthermore, the strength of the heat exchanger plate can also be ensured to ensure the safety and firmness of the heat exchanger plate and extend the service life of the heat exchanger plate.
[0012] In one implementation, a distance between an outer edge of the third boss and an outer edge of the fourth boss is greater than or equal to 0.5 mm and less than or equal to 5 mm.
[0013] In the case of adopting the above technical solution, since the distance between the outer edge of the third boss and the outer edge of the fourth boss is greater than or equal to 0.5 mm, it can be ensured that the size of the flow gap between the third boss and the heat exchange area meets the actual needs, so that the fluid medium entering the plate can flow into the above flow gap. Further, since the distance between the outer edge of the third boss and the outer edge of the fourth boss is less than or equal to 5 mm, it can be ensured that the area of the heat exchange area meets the actual needs, so as to ensure the heat exchange performance of the heat exchanger formed by the heat exchanger plates. Furthermore, the strength of the heat exchanger plates can also be ensured to ensure the safety and firmness of the heat exchanger plates and extend the service life of the heat exchanger plates.
[0014] In one implementation, along the direction from the first area to the second area, the second medium inlet hole and the first medium outlet hole are arranged opposite to each other, and the first medium inlet hole and the second medium outlet hole are arranged opposite to each other.
[0015] In one implementation, the boss is integrally formed.
[0016] In one implementation, the outer edge of the second medium inlet hole close to the heat exchange area is in the same straight line as the outer edge of the second boss.
[0017] In one implementation, the outer edge of the second medium outlet hole close to the heat exchange area is in the same straight line as the outer edge of the fourth boss.
[0018] In one implementation, the cross-sectional shape of the second boss is an arc shape, a broken line shape, or a curved line shape; and / or the cross-sectional shape of the fourth boss is an arc shape, a broken line shape, or a curved line shape.

[0036] See also Figure 1In the prior art, a heat exchanger generally includes a plurality of heat exchanger plates and a plurality of fins 7. The heat exchanger plate has a first region 10 and a second region 11 that are spaced apart, and a heat exchange region between the first region 10 and the second region 11. The heat exchanger plate is provided with a first medium inlet hole 2, a first medium outlet hole 3, a second medium inlet hole 4, and a second medium outlet hole 5 that are spaced apart. The first medium inlet hole 2 and the second medium inlet hole 4 are both located in the first region 10, and the first medium outlet hole 3 and the second medium outlet hole 5 are both located in the second region 11. The first medium inlet hole 2 and the first medium outlet hole 3 are arranged opposite to each other, and the second medium inlet hole 4 and the second medium outlet hole 5 are arranged opposite to each other.
[0037] In some heat exchanger plates, the first medium inlet holes 2 and the first medium outlet holes 3 that are relatively distributed are provided with bosses 6 on their outer peripheries. For two adjacent heat exchanger plates, one heat exchanger plate abuts against the other heat exchanger plate located above it through the bosses to form a sealed channel.
[0038] The fin 7 is arranged in the heat exchange area, and the two edges of the fin 7 are respectively close to one side of the two bosses 6. At this time, the fluid medium entering from the second medium inlet hole 4 is concentrated in the upper half of the heat exchanger plate, that is, the fluid medium can only flow from the second medium inlet hole 4 to the second medium outlet hole 5 in the horizontal direction, and the fluid medium cannot flow in the lower half of the heat exchanger plate, resulting in low heat exchange efficiency of the heat exchanger.
[0039] In order to solve the above technical problems, in the first aspect, the embodiment of the utility model provides a heat exchanger plate. Figures 2 to 5 The heat exchanger plate comprises: a plate 1. The plate 1 has a first region 10 and a second region 11 which are spaced apart, and a heat exchange region 12 which is located between the first region 10 and the second region 11. The plate 1 is provided with a first medium inlet hole 2, a first medium outlet hole 3, a second medium inlet hole 4 and a second medium outlet hole 5 which are spaced apart. The first medium inlet hole 2 and the second medium inlet hole 4 are both located in the first region 10, and the first medium outlet hole 3 and the second medium outlet hole 5 are both located in the second region 11. The boss 6 is provided on the plate 1, and is respectively arranged around the periphery of the first medium inlet hole 2 and the first medium outlet hole 3. The boss 6 arranged around the periphery of the first medium inlet hole 2 comprises a first boss 60 and a second boss 61 which are close to the heat exchange region 12, and the first boss 60 is located between the second boss 61 and the second medium inlet hole 4. For the same position of the heat exchange region 12, the spacing between the first boss 60 and the heat exchange region 12 is greater than the spacing between the second boss 61 and the heat exchange region 12. The spacing direction between the first boss 60 and the heat exchange region 12 and the spacing direction between the second boss 61 and the heat exchange region 12 are both consistent with the direction W from the first region 10 to the second region 11 .
[0040] The material and shape of the plate can be set according to actual conditions, and are not specifically limited here. In the embodiment of the utility model, the plate is a rectangular parallelepiped, and the direction from the first area to the second area is consistent with the length direction of the rectangular parallelepiped. Furthermore, the heat exchanger plate can also include other structures, which are not specifically limited here and can be set according to actual needs.
[0041] See also Figures 2 to 5 In the heat exchanger plate provided by the embodiment of the utility model, since the boss 6 is provided on the outer periphery of the first medium inlet hole 2 and the first medium outlet hole 3, the boss 6 can be used to abut against another heat exchanger plate located above it to form a sealed channel. Furthermore, since the boss 6 arranged around the outer periphery of the first medium inlet hole 2 includes a first boss 60 and a second boss 61 close to the heat exchange area 12, the first boss 60 is located between the second boss 61 and the second medium inlet hole 4. For the same position of the heat exchange area 12, the distance between the first boss 60 and the heat exchange area 12 is greater than the distance between the second boss 61 and the heat exchange area 12. At this time, the fluid medium entering the plate 1 from the first medium inlet hole 2 and the second medium inlet hole 4 can not only flow laterally in the direction from the second medium inlet hole 4 to the second medium outlet hole 5 (for example, along the Figure 2 The fluid medium can also flow in the direction from the second medium inlet hole 4 to the first boss 60 (for example, the direction indicated by the arrows A, B, and C in the figure) so that the fluid medium is distributed in the upper half of the plate heat exchange area 12. Figure 2 The fluid medium enters the flow gap between the first boss 60 and the heat exchange area 12, and then the fluid medium enters the lower half of the heat exchange area 12 (for example, the adjacent Figure 2 The position of the arrow F in the figure), and then flows out from the second medium outlet 5 (for example, the attached Figure 2 In the direction indicated by the arrow G in FIG. 1 ). Based on this, compared with the prior art, the area of the fluid medium flow is increased, the uniformity of the fluid medium distribution is improved, thereby improving the heat exchange efficiency of the heat exchanger and improving the heat exchange performance of the heat exchanger. In addition, the plate structure of the heat exchanger is simple, easy to manufacture, and easy to use, thereby improving work efficiency. It should be noted that the above-mentioned "upper half area" and "lower half area" can form a complete plate area.
[0042] As a possible implementation, see Figure 4 The distance L1 between the outer edge of the first boss 60 and the outer edge of the second boss 61 is greater than or equal to 0.5 mm and less than or equal to 5 mm. For example, the distance may be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm or 5 mm.
[0043] In the case of adopting the above technical solution, since the distance between the outer edge of the first boss 60 and the outer edge of the second boss 61 is greater than or equal to 0.5 mm, it can be ensured that the size of the flow gap between the first boss 60 and the heat exchange area 12 meets the actual needs, so that the fluid medium entering the plate 1 can flow into the above flow gap. Further, since the distance between the outer edge of the first boss 60 and the outer edge of the second boss 61 is less than or equal to 5 mm, it can be ensured that the area of the heat exchange area 12 meets the actual needs, so as to ensure the heat exchange performance of the heat exchanger formed by the heat exchanger plates. Furthermore, the strength of the heat exchanger plates can also be ensured to ensure the safety and firmness of the heat exchanger plates and extend the service life of the heat exchanger plates.
[0044] As a possible implementation, see Figure 3 and Figure 6 The outer edge of the second medium inlet hole 4 close to the heat exchange area 12 is in the same straight line Q as the outer edge of the second boss 61 .
[0045] As a possible implementation, see Figures 2 to 5 The bosses arranged around the outer periphery of the first medium outlet hole 3 include a third boss 62 and a fourth boss 63 close to the heat exchange area 12, and the third boss 62 is located between the fourth boss 63 and the second medium outlet hole 5. For the same position of the heat exchange area 12, the spacing between the third boss 62 and the heat exchange area 12 is greater than the spacing between the fourth boss 63 and the heat exchange area 12. The spacing direction between the third boss 62 and the heat exchange area 12 and the spacing direction between the fourth boss 63 and the heat exchange area 12 are both consistent with the direction W from the first area 10 to the second area 11.
[0046] In the case of adopting the above technical solution, combined with the above description, when the fluid medium enters the lower half of the heat exchange area 12 from the flow gap between the first boss 60 and the heat exchange area 12, the fluid medium located in the lower half of the heat exchange area 12 can not only flow out from the original area between the first medium outlet hole 3 and the second medium outlet hole 5 (for example, the attached area) but also can flow out from the original area between the first medium outlet hole 3 and the second medium outlet hole 5. Figure 2 The heat exchange area 12 and the third boss 62 may also flow out from the flow gap between the heat exchange area 12 and the third boss 62 (for example, the adjacent Figure 2 At this time, not only the flow speed of the fluid medium is accelerated, but also the flow area of the fluid medium is increased, thereby improving the heat exchange efficiency of the heat exchanger and improving the heat exchange performance of the heat exchanger.
[0047] In an alternative approach, see Figure 5The distance L2 between the outer edge of the third boss 62 and the outer edge of the fourth boss 63 is greater than or equal to 0.5 mm and less than or equal to 5 mm. For example, the distance may be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm or 5 mm.
[0048] In the case of adopting the above technical solution, since the distance between the outer edge of the third boss 62 and the outer edge of the fourth boss 63 is greater than or equal to 0.5 mm, it can be ensured that the size of the flow gap between the third boss 62 and the heat exchange area 12 meets the actual needs, so that the fluid medium entering the plate 1 can flow into the above flow gap. Further, since the distance between the outer edge of the third boss 62 and the outer edge of the fourth boss 63 is less than or equal to 5 mm, it can be ensured that the area of the heat exchange area 12 meets the actual needs, so as to ensure the heat exchange performance of the heat exchanger formed by the heat exchanger plates. Furthermore, the strength of the heat exchanger plates can also be ensured to ensure the safety and firmness of the heat exchanger plates and extend the service life of the heat exchanger plates.

Specifically, the first medium inlet hole 2, the first medium outlet hole 3, the second medium inlet hole 4 and the second medium outlet hole 5 are distributed at the four corners of the plate 1.

At this time, the fluid medium can not only flow out from the flow gap between the heat exchange area 12 and the third boss 62 (for example, the adjacent Figure 2 The position indicated by the arrow M in the figure) can also flow out from the original area between the first medium outlet 3 and the second medium outlet 5 (for example, the adjacent Figure 6 Further, the fluid medium can also flow in the direction from the second medium inlet hole 4 to the first boss 60 (for example, the adjacent Figure 2 The fluid medium enters the flow gap between the first boss 60 and the heat exchange area 12, and then the fluid medium enters the lower half of the heat exchange area 12 (for example, the adjacent Figure 6 The fluid flows out from the second medium outlet 5. At this time, not only the flow speed of the fluid medium is accelerated, but also the flow area of the fluid medium is increased, thereby improving the heat exchange efficiency of the heat exchanger and improving the heat exchange performance of the heat exchanger.
