The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.

Referring to fig. 1-5, a turbulent slot type liquid-cooled plate radiator, comprises: the liquid cooling plate 100 and the copper pipe 200 installed on the liquid cooling plate 100, the copper pipe 200 is provided with an inlet end 210 and an outlet end 220, the copper pipe 200 is internally provided with a flow guide rib 230 for changing the flow direction of the liquid medium in the copper pipe 200, and the flow guide rib 230 guides the liquid medium to rotationally flow in the copper pipe 200.

As shown in fig. 1, the liquid cooling plate 100 is made of a metal plate with good heat conduction performance, the copper pipe 200 can be installed at the liquid cooling plate 100 in an interference manner or embedded manner, the liquid cooling plate 100 is provided with an installation area, and the heating element 300 is installed at the installation area;

the heat generated by the heating element 300 during operation is transferred to the liquid cooling plate 100 and the copper pipe 200, the liquid medium in the copper pipe 200 flows in the copper pipe and absorbs the heat, and the heat is uniformly transferred to the liquid cooling plate 100, so that the purpose of uniform temperature is achieved, and the heat dissipation effect is better;

as shown in fig. 3 and 5, the guide rib 230 protrudes from the inner wall of the copper pipe 200 and is inclined; as shown in fig. 7, the liquid medium flows in the copper pipe 200, the flow direction of the liquid medium flows to the guide rib 230, the flow direction is changed from straight flow to inclined flow under the guide of the guide rib 230, the copper pipe 200 is provided with an arc-shaped inner wall, and finally the liquid medium flows in the copper pipe 200 in a rotating way, and the flow path is shown by an arrow direction in fig. 7.

As shown in fig. 5, under the condition that the guide ribs 230 are not provided, the liquid medium flows straight from left to right, so that the upper layer liquid medium absorbs heat generated during operation of the heating element 300 through the copper pipe wall, and the lower layer liquid medium absorbs heat of the upper layer liquid medium and transfers the heat to the liquid cooling plate 100, so that heat transfer is slowed down, and after the guide ribs 230 are provided, the liquid medium flows in the copper pipe 200 in a rotating way, and then the lower layer liquid medium rotates to the upper layer position, absorbs heat generated during operation of the heating element 300 through the copper pipe wall, so that the heat dissipation effect can be quickened.

Further, the liquid medium may be water, a cooling liquid, or the like.

Further, the copper tube 200 is a hollow copper tube, and the thickness of the copper tube wall is relatively thin, so that the purpose of rapid heat conduction can be met, and the copper tube is not easy to break.

In one embodiment, the copper tube 200 has an inlet end 210 and an outlet end 220, wherein the inlet end 210 and the outlet end 220 are externally connected with a water cooling system, so that the liquid medium circularly flows in the copper tube 200; the specific structure of the water cooling system can be a common technical means for those skilled in the art, and detailed description thereof will be omitted.

In one embodiment, the surface of the liquid cooling plate 100 is provided with an inner groove 110, the copper pipe 200 is embedded in the groove 110, the outer wall of the copper pipe 200 contacts with the inner wall of the inner groove 110, and after the copper pipe 200 is installed, at least the inlet end 210 and the outlet end 220 of the copper pipe 200 extend out of the liquid cooling plate 100, so that the copper pipe is convenient to be connected with a water cooling system;

in the present embodiment, as shown in fig. 1, the U-shaped tube section of the copper tube 200 also extends out of the liquid cooling plate 100, but in practice, it is not limited whether the U-shaped tube section extends out of the liquid cooling plate 100.

In one embodiment, the circumference of the inner groove 110 is smaller than the outer circumference of the copper tube 200, so that the upper surface of the copper tube 200 protrudes out of the inner groove 100 after the copper tube 200 is mounted, and in order to make the copper tube 200 and the liquid cooling plate 100 better contact with the heating element 300, the copper tube 200 protrudes out of the inner groove 110 to form a plane 201 by compression, the plane 201 is level with the first surface 101 of the liquid cooling plate 100, and the heating element 300 can be maximally contacted with the copper tube 200 and the liquid cooling plate 100 when mounted, thereby increasing the heat conduction area.

Further, the area where the heating element 300 is installed at the plane 201 and the first surface 101 is coated with a heat conducting layer, and the heat conducting layer may be a heat conducting paste, a heat conducting glue, etc., so as to increase heat conducting performance;

in fig. 1, the liquid cooling plate 100 is provided with two heating elements 300, and thus two installation areas are provided, each of which is coated with a heat conductive layer; alternatively, the heat conductive layer may be coated on the first surface 101 of the entire liquid cooling plate 100 and the surface of the copper pipe 200, but this may cause a certain waste of resources.

In one embodiment, the flow guiding ribs 230 are disposed in the copper pipe 200 and can guide the liquid medium in the copper pipe 200 to flow in a rotating way, so that the flow guiding ribs 230 are all inclined, and the copper pipe 200 is at least provided with the flow guiding ribs 230 on the bottom surface contacting with the inner groove 110, so that the liquid medium flowing in the copper pipe 200, particularly the liquid medium in the lower layer, can flow upwards in an inclined way to push the liquid medium in the upper layer to the lower layer to perform better heat exchange after meeting the flow guiding ribs 230, and the arc-shaped inner wall of the copper pipe 200 is matched.

However, in the copper pipe 200, as shown in the 5-direction, in practice, the guide ribs 230 may be provided on the end surface and the side surface of the copper pipe 200 to guide the rotational flow of the liquid medium.

However, if the guide rib 230 is provided at the end surface of the copper pipe 200 to increase the thickness of the copper pipe 200 to some extent, which hinders heat exchange with the heating element 300, it is preferable that the guide rib 230 is provided at the inner bottom surface of the copper pipe 200.

Alternatively, it is also possible to provide the guide rib 230 at the end surface thereof at a position where the pass-through 200 is not in contact with the heating element 300;

the number and position distribution of the guide ribs 230 can be adaptively changed, and the liquid medium can be guided to flow in a rotating way.

In one embodiment, the ribs 230 are generally formed in two ways,

firstly, the guide rib 230 is directly pressed and formed at the copper pipe 200 in the process of processing the copper pipe 200, but the method needs to separately process the copper pipe 200, so that the process difficulty and the product processing difficulty are increased;

secondly, a boss 111 is provided on the bottom surface of the inner groove 110, and when the copper pipe 200 is pressed into the inner groove 110, the copper pipe 200 is pressed by the boss 111 to form the guide rib 230; the outer wall of the copper pipe 200 is correspondingly formed with a concave position 240; in this way, when the copper pipe 200 is assembled in the inner groove 110 in an interference manner, the guide rib 230 can be directly jacked up in the copper pipe 200 through the boss 111 because the pipe wall of the copper pipe 200 is relatively thin.

The first way increases the difficulty of the processing technology, but it may be that the guide ribs 230 are disposed at a plurality of different wall surfaces in the copper pipe 200;

the second mode is simple, but is only suitable for providing the guide rib 230 at the bottom wall of the copper pipe 200; during production, different processing modes can be selected according to requirements.

Further, as shown in fig. 6, the angle α between the flow direction of the liquid medium and the flow direction of the flow guiding rib 230 is set, and the value range of α is: alpha is more than or equal to 30 degrees and less than or equal to 60 degrees;

the inclination angle and the distribution density of the guide rib 230 affect the rotation path of the liquid medium in the copper pipe 200, if the inclination angle of the guide rib 230 is too large, a reverse impact force is easily generated to prevent the liquid medium from moving forward, and if the inclination angle of the guide rib 230 is too large, the liquid medium is not easy to complete rotation, so the included angle α is preferably 45 °.

In one embodiment, the copper pipe 200 is wound around the liquid cooling plate 100 in a roundabout manner; the liquid cooling plate 100 and the copper pipe 200 cooperate to form at least one area for assembling the heating element 300;

as shown in fig. 1, two heating elements 300 are assembled on the liquid cooling plate 100, and in other embodiments, the number and the positions of the heating elements 300 can be changed, so that the requirements of actual use are more urgent and the heating elements can be adaptively changed; in addition, in the present embodiment, a set of copper tubes 200 is disposed at the liquid cooling plate 100, and the flow paths of the copper tubes 200 flow through two heating elements 300, alternatively, two sets of copper tubes 200 may be disposed at the liquid cooling plate 100, and two sets of copper tubes 200 may flow through one heating element 300 respectively;

if three heating elements 300 are disposed on the liquid cooling plate 100, a group of copper tubes 200 may be selected to flow through the three heating elements 300, two groups of copper tubes 200 may be selected to be disposed, wherein one group of copper tubes 200 flows through two heating elements 300, one copper tube 200 flows through another heating element 300, or three groups of copper tubes 200 may be disposed to flow through single-pass heating elements 300.

Further, the heating element 300 is located on the IGBT element and is locked on the first surface 101 of the liquid cooling plate 100 by a screw, and is in close contact with the liquid cooling plate 100 and the copper pipe 200.

In one embodiment, the copper pipe 200 is provided with at least a straight line segment 203 and an arc segment 202, as shown in fig. 1 and 2, wherein the copper pipe 200 is designed into a U shape, and the guide rib 230 is arranged in the straight line segment 203; optionally, the shape of the copper tube 200 may be adaptively changed, which is changed according to the number of the heating elements 300 and the installation position, so as to increase the flow length of the copper tube 200 on the liquid cooling plate 100 as much as possible, thereby enhancing the heat exchange effect.
