Abstract
The utility model discloses a built-in type water-cooling heat radiation board for a power module, which comprises an integral substrate. Watercourses are drilled inside the substrate. The watercourses are provided with at least a water inlet and at least a water outlet on the side face of the substrate. The built-in type water-cooling heat radiation board for the power module has the beneficial effects that by adopting the integral substrate, the water leakage phenomenon can be effectively avoided under a continuous vibration condition, the heat radiation effect of the power module can be improved, running of a device is more reliable, difficulty of production technology can be reduced and the production cost can be reduced.
Description
Technical field
The utility model relates to a kind of power model and uses built-in water-cooling plate.
Background technology
Along with the fast development of power electronic technology, power model is as the core component of current transformer, and its cooling technology is very crucial, directly has influence on the reliability of equipment operation.The main type of cooling of existing power model has: natural cooling, forced air cooling, boiler water circulation cooling etc.; Wherein the boiler water circulation cooling is with its good cooling results; The heat-radiating substrate volume is little, particularly can more and more be used widely with the shared same water circulation system of other parts that need cool off in the system.
Generally be employed in the substrate of surface fluting, add a cover plate again, play heat sinking function, but this kind structure can not guarantee good sealing under the condition that continues vibrations, occur the situation of infiltration easily, influence the life-span of equipment through the fluid sealant sealing.
Summary of the invention
Be technical deficiency more than solving, it is a kind of simple in structure that the utility model provides, and the power model of having avoided drainage under the condition that continues vibrations, occurring is used built-in water-cooling plate.
The utility model is realized through following measure:
A kind of power model of the utility model is used built-in water-cooling plate, comprises a monolith substrate, said base
Be drilled with water channel in the plate, said water channel is provided with a water inlet and a delivery port at least in substrate side surfaces.
Above-mentioned water channel comprises some cross channels and two the vertical water channels that are connected, and cross channel is in substrate side surfaces
The equal shutoff of opening sealing screw is arranged, said two vertical water channels at two openings of substrate side surfaces respectively as water inlet and delivery port.
Aforesaid substrate is an aluminum material.
The beneficial effect of the utility model is:
Adopt monolith substrate, effectively avoided under the condition that continues vibrations, drainage occurring, improved the radiating effect of power model, make equipment operation more reliable, reduced the manufacture craft difficulty, reduced cost of manufacture.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model.
Among the figure: 1 substrate, 2 vertical water channels, 3 cross channels, 4 sealing screws, 5 water inlets, 6 delivery ports.
Embodiment
As shown in Figure 1, a kind of power model of the utility model is used built-in water-cooling plate, comprises an integral body and has certain thickness substrate 1, and be drilled with water channel in the substrate 1, water channel is provided with a water inlet 5 and a delivery port 6 at least in substrate side surfaces.Cooling water gets into water channel from water inlet 5, flows out from delivery port 6 then, takes away heat.Water channel can be drilled to tortuous circuitous passage also can be drilled to crisscross form.
Enumerate a kind of embodiment at present, water channel be drilled to some cross channels 3 and two the vertical water channels 2 that are connected,
Cross channel 3 has sealing screw 4 in the equal shutoff of opening of substrate 1 side, adds fluid sealant, plays the effect of sealing.Two vertical water channels 2 at two openings of substrate 1 side respectively as water inlet 5 and delivery port 6.Processing is got up more conveniently like this, and cost is lower.Substrate 1 aluminium prepared material, heat-conducting effect is better.Be applicable to the heat radiation of IGBT, IPM constant power module.
The foregoing description is said to be in order to specify this patent; Though describe through specific term in the literary composition; But can not limit the protection range of this patent with this; The personage who is familiar with this technical field can change or revise it after the spirit of understanding this patent and principle and reach equivalent purpose, and this equivalence change and modification all should be covered by the claim scope and define in the category.
Claims (3)
1. a power model is used built-in water-cooling plate, it is characterized in that: comprise a monolith substrate, be drilled with water channel in the said substrate, said water channel is provided with a water inlet and a delivery port at least in substrate side surfaces.
2. use built-in water-cooling plate according to the said power model of claim 1; It is characterized in that: said water channel comprises some cross channels and two the vertical water channels that are connected; Cross channel has sealing screw in the equal shutoff of the opening of substrate side surfaces, said two vertical water channels at two openings of substrate side surfaces respectively as water inlet and delivery port.
