Single side, bulky structure can not meet the requirements.
The content of the invention
The technical problems to be solved in the utility model is：Provide low pair of a kind of simple in structure, perfect heat-dissipating, cost
Face cools down radiator, solves the problems, such as that traditional Automobile drive radiator volume is larger.
In order to solve the above-mentioned technical problem, the technical solution of the utility model there is provided a kind of two-sided cooling radiator,
It is characterised in that it includes upper cold plate, upper cold plate is docked by its own connector with middle cold plate, middle cold plate by its own connector with
The docking of lower cold plate, be clamped between upper cold plate and middle cold plate, between middle cold plate and lower cold plate one layer be used for exchange heat insulated gate
Bipolar transistor.
Preferably, the upper cold plate, middle cold plate, lower cold plate are fastened together by screw
Preferably, the upper cold plate is equipped with least two threaded hole, is located on middle cold plate and lower cold plate on upper cold plate
The corresponding position of threaded hole is equipped with unthreaded hole, and screw is passed through from the back side of lower cold plate, passes through the spiral shell on middle cold plate, with upper cold plate
Pit connects.
Preferably, the upper cold plate, middle cold plate, lower cold plate connect by vacuum brazing or atmosphere protection welding and
Into cold plate is internally provided with the fin beneficial to heat dissipation.
Preferably, it is equipped between the insulated gate bipolar transistor and upper cold plate, middle cold plate, lower cold plate for subtracting
Small thermal contact resistance and the insulating heat-conductive rubber cushion of insulation.
Preferably, the both sides of the upper cold plate are equipped with two supporting racks.
Two-sided cooling radiator provided by the utility model overcomes the deficiencies in the prior art, its appearance is neatly beautiful, knot
Structure is simple, and size is small, light-weight, and easy to extend, heat dissipation performance is good, and cost is relatively low, and the flow distribution between cold plate in parallel is equal
It is even.
Brief description of the drawings
Fig. 1 is a kind of explosive view of two-sided cooling radiator；
Fig. 2 is a kind of assembling figure of two-sided cooling radiator.
Embodiment
To become apparent the utility model, hereby with preferred embodiment, and attached drawing is coordinated to be described in detail below.
The utility model is a kind of two-sided cooling radiator, as shown in Figure 1 and Figure 2, it include cold plate 1, middle cold plate 2, under
Cold plate 3 and screw 4.Upper cold plate 1 is docked by its own connector with middle cold plate 2, and middle cold plate 2 passes through its own connector and lower cold plate
3 docking, finally upper cold plate 1, middle cold plate 2, lower cold plate 3 are fastened together by screw 4.Two among three cold plate clampings
Layer IGBT exchanges heat, i.e., upper one layer is clamped between cold plate 1 and middle cold plate 2, between middle cold plate 2 and lower cold plate 3 to be used to exchange heat
IGBT.Screw 4 is each passed through lower cold plate 3, middle cold plate 2 and upper cold plate 1 to be combined into a radiator group.The two of upper cold plate 1
Side is equipped with two supporting racks.
The utility model clamps one layer of IGBT between using two panels cold plate, passes through insulating heat-conductive rubber cushion between IGBT and cold plate
To reduce thermal contact resistance and insulation.The pressure of the radiator clamping IGBT of the utility model through the screw 4 of cold plate by locking
Gu applying, client can obtain different chucking powers and thermal contact resistance by different screw locking power.
3 independent cold plates (including connector) are welded by vacuum brazing or atmosphere protection in advance, in the cold plate of welding
Portion includes corresponding fin in favor of heat dissipation, then by processing the flatness and shape requirement on acquisition cold plate surface, upper cold plate 1
In contain 4 threaded holes, be unthreaded hole in middle cold plate 2 and lower cold plate 3.
During the cold plate assembling of the utility model, 3 pieces of cold plates (cold plate 1, middle cold plate 2, lower cold plate 3 on i.e.) are by each above
Connector docking get up after, passed through with screw 4 from lower 3 back side of cold plate (non-connector face), by middle cold plate 2, be fixed on cold plate 1
On threaded hole in.At this point it is possible to be inserted into IGBT module among two blocks of cold plates, screw 4 is tightened finally by electric wrench
Obtain the pressure of clamping IGBT.
