[0032] Embodiment 1

[0033] See also Figures 1 to 3 As shown, the heat exchange plate with integrated spoiler and guide functions provided by the present application includes a plate body 101 and a plurality of protrusions 102 formed on the plate body 101. Generally speaking, in a heat exchanger, a plurality of heat exchange plates are arranged at intervals to form a coolant side cavity and an oil side cavity in sequence. Specifically, the plate body 101 is provided with a first liquid inlet hole 103 and a first liquid outlet hole 104, and the circumference of the first liquid inlet hole 103 and the circumference of the first liquid outlet hole 104 are both formed with a first flange in the same direction, and adjacent heat exchange plates are isolated from a sealed oil side cavity by connecting the first flange. On the side of the plate body 101 where the protrusion 102 is formed, that is, in the coolant side cavity, the coolant can flow from the first liquid inlet hole 103 to the first liquid outlet hole 104.

[0034] A plurality of protrusions 102 are arranged at various places of the plate body 101 along the preset path 105 to disrupt the flow of the coolant and increase the heat exchange effect. The protrusions 102 are strip-shaped, and the length direction of the protrusions 102 is the same as the extension direction of the preset path 105, that is, the protrusions 102 can be offset at a certain angle so that the placement of the protrusions 102 can follow the direction of liquid flow, thereby guiding the coolant to various places of the plate body 101, and the coolant flowing out of the first liquid inlet hole 103 can be quickly spread to the entire plate body 101, the circulation space is increased, and the resistance of the entire cooling plate to the coolant is reduced.

[0035] The heat exchange plate with integrated spoiler and guide functions provided in the present application is provided with a plurality of strip-shaped protrusions 102 on the plate body 101. The strip-shaped protrusions 102 are arranged on the plate body 101 according to a preset path 105, and the deflection angle of the protrusions 102 is set. The spoiler function is achieved while guiding the coolant. The coolant can be quickly spread to the entire plate body 101, thereby increasing the circulation space of the coolant and reducing the resistance of the entire cooling plate to the coolant.

[0036] In an optional solution of this embodiment, the board body 101 is rectangular, the first liquid inlet hole 103 is opened at a corner of the board body 101, and the first liquid outlet hole 104 is opened at the opposite corner of the board body 101 to lengthen the flow path of the coolant and achieve better heat dissipation effect.

[0037] Multiple protrusions 102 arranged on the circumference of the first liquid inlet hole 103 and away from the edge of the plate body 101 are radially distributed, and multiple protrusions 102 arranged on the circumference of the first liquid outlet hole 104 and away from the edge of the plate body 101 are radially distributed. For the first liquid inlet hole 103, the radially distributed protrusions 102 can quickly disperse the coolant to the plate surface of the plate body 101. For the first liquid outlet hole 104, the radially distributed protrusions 102 can quickly gather the coolant from the plate surface of the plate body 101 to the first liquid outlet hole 104, thereby increasing the coolant flow rate and improving the heat exchange effect.

[0038] In an optional solution of this embodiment, the plate body 101 is rectangular, and in the middle of the plate body 101 along its own length direction, the length directions of the multiple protrusions 102 are consistent with the length direction of the plate body 101, so that the coolant can flow along the length direction of the plate body 101, ensuring that the heat exchange effect of the plate body 101 is better at various locations in the length direction.

[0039] In an optional scheme of this embodiment, in the middle of the plate body 101 along its own length direction, multiple protrusions 102 are arranged at intervals to form multiple protrusion rows, and the extension direction of the protrusion rows is the length direction of the plate body 101. The multiple protrusion rows are equidistantly arranged along the width direction of the plate body 101, so that the coolant flow between the protrusion rows is equal, ensuring that the heat exchange effect at each position of the plate body 101 is more uniform; the protrusions 102 of two adjacent protrusion rows are staggered, and when the coolant flows around the protrusions 102, it will not be blocked by the protrusions 102 of the adjacent protrusion rows, thereby increasing the flow effect and further increasing the heat exchange effect.

[0040] In an optional solution of this embodiment, multiple protrusions 102 in the protrusion row are arranged equidistantly and spaced by a preset distance, and the offset distance between adjacent protrusion rows is half of the preset distance. The regular arrangement of the protrusions facilitates the production of the heat exchange plate on the one hand, and also ensures that the heat exchange effect of the plate body 101 is more uniform on the other hand.

[0041] In an optional solution of this embodiment, the plurality of protrusions 102 arranged on the plate body 101 are centrally symmetrically arranged with the midpoint of the rectangular plate body 101 as the center, and the first liquid inlet 103 and the first liquid outlet 104 are centrally symmetrically arranged.

[0042] In this embodiment, the surfaces of the centrally symmetrical heat exchange plates forming the protrusions 102 can be opposed to each other to form a cooling liquid side cavity. On the opposite heat exchange plates, the functions of the first liquid inlet hole 103 and the first liquid outlet hole 104 are interchanged, and the protrusions 102 on the opposite heat exchange plates are arranged relative to each other. The double-sided protrusions 102 can realize the functions of disturbing and guiding the cooling liquid, and the universal production of the heat exchange plates is realized, thereby reducing the production cost.

[0043] Embodiment 2

[0044] The heat exchange plate with integrated spoiler and guide functions in the second embodiment is an improvement on the above embodiment. The technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0045] In an optional solution of this embodiment, the plate body 101 is further provided with a second liquid inlet hole 106 and a second liquid outlet hole 107. The second liquid inlet hole 106 and the second liquid outlet hole 107 are centrally symmetrically arranged with the midpoint of the rectangular plate body 101 as the center; similarly, on the opposite heat exchange plates, the functions of the second liquid inlet hole 106 and the second liquid outlet hole 107 are interchangeable, thus realizing the universal production of heat exchange plates. The circumference of the second liquid inlet hole 106 and the circumference of the second liquid outlet hole 107 are both formed with second flanges in the same direction, and adjacent heat exchange plates are connected by connecting the second flanges to isolate a sealed cooling liquid side cavity.

[0046] The direction from the second liquid inlet hole 106 to the second liquid outlet hole 107 is opposite to the direction from the first liquid inlet hole 103 to the first liquid outlet hole 104. On the other side of the plate body 101, the cooling medium can flow from the second liquid inlet hole 106 to the second liquid outlet hole 107; that is, for the heat exchange plate, the flow directions of the liquids on both sides are opposite to increase the heat exchange effect.

[0047] At the positions of the second liquid inlet hole 106 and the second liquid outlet hole 107 opened in the plate body 101, a plurality of protrusions 102 are arranged around the second liquid inlet hole 106 and the second liquid outlet hole 107, and the deflection angle of each protrusion 102 is different. Taking the second liquid inlet hole 106 as an example, taking the tangent line of the protrusion mapped at the position of the second liquid inlet hole 106 as a reference, the deflection angle of the protrusion relative to the corresponding tangent line is within a certain range, which can be specifically 0-60 degrees. On the one hand, it ensures the guiding effect of the coolant, and on the other hand, a plurality of protrusions 102 are arranged around the second liquid inlet hole 106 and the second liquid outlet hole 107. Since the strength of the opening position of the plate body 101 is relatively weak, the protrusions 102 are arranged around the second liquid inlet hole 106 and the second liquid outlet hole 107, which can increase the strength of this place. The protrusions 102 arranged around the second liquid outlet hole 107 are the same as the protrusions 102 arranged around the second liquid inlet hole 106, and will not be repeated here.

[0048] In an optional solution of this embodiment, the protrusion 102 is tapered from the maximum width position of the protrusion 102 toward the direction where the protrusion 102 approaches the first liquid inlet hole 103, that is, the contact area between the end of the protrusion 102 facing the coolant and the coolant is smaller, thereby reducing the resistance to the coolant.

[0049] It should be noted that the maximum width position of the protrusion 102 can be set to be equal width or gradually shrink towards the end away from the coolant, and the above situations are all within the protection scope of this application. Preferably, the maximum width position of the protrusion 102 is gradually shrinking towards the end away from the coolant, so that the separated coolant can be gathered again at this place, thereby enhancing the turbulence effect.

[0050] In an optional solution of this embodiment, the side of the protrusion 102 away from the plate body 101 is the top surface 108 of the protrusion 102, and the top surface 108 is a plane. The plate surfaces of the heat exchange plate forming the protrusion 102 are opposite to each other, and the top surface 108 of the protrusion 102 is arranged in a close fit to make the cooling liquid cavity structure more stable and increase the strength of the device.

[0051] Specifically, the cross section of the protrusion 102 perpendicular to its own height direction may be elliptical or oval. Figure 2 As shown, a protrusion 102 having an elliptical cross section is shown.

[0052] In an optional solution of this embodiment, the protrusion 102 is stamped; the connection between the protrusion 102 and the plate body 101 is an arc transition, and the side wall 109 of the protrusion 102 is an arc transition with a side of the protrusion 102 away from the plate body 101 to reduce the resistance to the coolant.
