The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in the figure, the big plane of this plate wing belly core module heat radiator, mainly comprise coldplate 1 and following coldplate 2, described coldplate 1 and two flat aluminium sheets of big area of following coldplate 2 employings gone up, and connect face at the card of last coldplate 1 and following coldplate 2 and be processed into a large-area cavity 8, plate wing heat conduction central layer 3 is installed in this cavity 8, and upper and lower two planes of plate wing heat conduction central layer 3 are to be close to the inwall plane of cavity 8 and contact, and will go up coldplate 1 and following coldplate 2 then and be welded into a whole.The outer surface of last coldplate 1 and following coldplate 2 constitutes cooling table top 12, the unevenness and the roughness of cooling table top 12 are processed by the high standard requirement, have module on the cooling table top 12 screw 13 is installed, the heat load module is installed on the module installation screw 13 is close to the aluminium sheet plane, and whole then the plating forms.Two sides of cavity 8 are connected with water inlet pipe 5, outlet pipe 6 respectively by hose coupling 4, be provided with branch water plate 9 in current import and export position in the cavity 8, divide on the water plate 9 and have a component water hole 9-1, the guiding current evenly flow with spray regime crash panel wing chip and toward width when entering tapping hole 9-1, solved because the module heat radiator width is big, cooling water flow is out-of-date easily to cause the irregular problem that worsens electric property of module Yin Wendu because of skewness.
Plate fin in the described plate-fin heat conduction central layer 3 becomes triangle arrangement by water (flow) direction, impels current fully to collide disturbance to improve thermal conductivity factor; Flatness that plate-fin heat conduction central layer 3 upper and lower surfaces are good and the certain elasticity of tool so as to go up coldplate 1 and following coldplate 2 when compressing plate-fin heat conduction central layer 3 be close to wall with the minimizing thermal resistance with elastic force.
Because this radiator table top broad, when around when welding close-fitting, last coldplate 1 and following coldplate 2 very easily intermediate projections cause with 3 loose contacts of plate-fin heat conduction central layer and increase thermal resistance; This utility patent adopts 2 kinds of structures or technology to solve:
1, as shown in Figure 7, adopt the tight flat bolt 7 of stainless steel, last coldplate 1 buried via hole, rib-loop in the following coldplate 2 is close to plate-fin heat conduction central layer 3 in order to force coldplate 1, following coldplate 2; Tight flat bolt 7 heads are with 10 sealings of long-term seal pad, and the top mills out seamless with shutoff sheet 11 (aluminium garden sheet) welding shutoff again; Tight flat bolt 7 can adopt many, and correct position buries dress around reaching in the centre.
2, will go up coldplate 1 and be pressed into camber a little, protuberance pastes plate-fin heat conduction central layer 3, and when densification all around, the middle part helps plate-fin heat conduction central layer 3 with its camber elastic force and is close to.
The course of work: under the water flowing operating mode, module energising work, the heat of its generation passes to the cooling water that flows by cooling table top 12 and plate wing heat conduction central layer 3 and takes out of outside the radiator, to keep module safe operation in the design temperature scope.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
