Embodiment
Below in conjunction with embodiment and Figure of description, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
As shown in Fig. 1 ~ 4, a kind of coldplate for power brick liquid cooling, comprise flow plate 1, flat board 2, inlet union 3 and outlet connection 4, flow plate 1 is tightly connected with dull and stereotyped 2, inlet union 3 and outlet connection 4 are sealedly attached to dull and stereotyped 2, and inlet union 3 is all communicated with flow plate 1 with outlet connection 4, thus cooling fluid is facilitated to circulate in plate 1 and dull and stereotyped 2 formation runners.Flow plate 1 is aluminium, magnesium, iron and other be easy to weld, thermal conductivity is good and be easy to the material of punching press, because flow plate 1 requires regular shape and simple, so flow plate 1 is made (low because of stamping parts handling ease, cost of manufacture) by punch forming process; The two sides of dull and stereotyped 2 is the plane of polishing, its material can be aluminium, magnesium, iron and other be easy to weld and the good material of thermal conductivity; The material of inlet union 3 and outlet connection 4 also can be aluminium, magnesium, iron and other be easy to weld and the good material of thermal conductivity.Flow plate 1, dull and stereotyped 2, inlet union 3 and outlet connection 4 all adopt aluminium, magnesium, iron and other be easy to weld and the good material of thermal conductivity, be conducive to coldplate like this and better dispel the heat.
Described flow plate 1 comprises flow plate body 11, is arranged at the boss 12 of flow plate body 11 and is positioned at the barrier rib 13 in the middle part of flow plate body 11.Flow plate body 11 and barrier rib 13 form the runner of one " U " shape structure.Flow plate body 11 is provided with flange face, and the end face of flange face and boss 12 is in same plane, and when flow plate body 11 and flat board 2 are welded together, boss 12 can play the effect of the liquid intercepting flowing.
Preferably, boss 12 is set to circular configuration, because circular configuration is when punching press, material is all relatively more even in all directions drawing, is not easy to occur local damage; Importantly this circular configuration compares the structure of other shapes, and current can be made to flow more mild, flow resistance is lower.Certainly, also can be set to oval structure or square structure as required, do not done concrete restriction here.Boss 12 adopts 3 to be row and 4 to be the mode of row to be alternately uniformly distributed in flow plate body 11, the runner of " U " shape structure is made to form many crisscross small flow channels, after cooling fluid passes into cooling fluid from inlet union 3, cooling fluid flows into the runner of " U " shape structure, then by small flow channels shunting (because the small flow channels in the runner of " U " shape structure interconnects), cooling fluid just changes direction after touching boss 12, fluid turbulence is flowed, so the equilibrium of fluid pressure can be ensured and realize the balance of flow, thus reduce the inhomogeneities (direction of flow schematic diagram as shown in Figure 5) of flow.The both sides of the edge of flow plate body 11 and barrier rib 13 are provided with arc sections 14, the position of arc sections 14 corresponds to the position that 3 are the boss 12 of row, this arc sections 14 carries out flow-disturbing to the liquid flowed jointly with boss 12, makes fluid occur more uniform Turbulence Flow.
Preferably, flow plate 1 adopts the mode of welding to be tightly connected with dull and stereotyped 2, and inlet union 3 and outlet connection 4 all adopt the mode of welding to be sealedly attached to dull and stereotyped 2, because the effect adopting the mode of welding to carry out sealing can be better.
Preferably, the manufacturing process of dull and stereotyped 2 is simple, can adopt the technique such as punching press, casting.Dull and stereotyped 2 directly contact with the end face of boss 12, when there being weight to press down the utility model, play good supporting role; In addition, boss 12 opposing plates 2, adds the area of dissipation with the external world, improves heat dispersion.Flat board 2 is provided with two through holes 21 arranged side by side, and inlet union 3 and outlet connection 4 are seal-installed on two through holes 21 respectively.
Preferably, the outer wall of inlet union 3 and outlet connection 4 is provided with helicitic texture, and the mode that the utility model can be threaded connection is connected with other fluid passages.Certainly, inlet union 3 and outlet connection 4 as the joint of rubber tube, also can also can adopt the mode of flange to be connected with other fluid passages, also can be connected with quick connector as required.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also change above-mentioned execution mode and revise.Therefore, the utility model is not limited to above-mentioned embodiment, and any apparent improvement of every those skilled in the art done by basis of the present utility model, replacement or modification all belong to protection range of the present utility model.In addition, although employ some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
