Abstract

The utility model relates to a large power thyristor modular which can save space, reduce the cost, has good heat radiation effect and can relieve the contradiction of the power and the junction temperature rise, and is composed of a casing, an electrode assembly, a pipe core and a bottom plate. The inner part of the bottom plate is also provided with a cavity body, and a water inflow mouth and a water outflow mouth which are communicated with an inlet and an outlet of the cavity body are arranged respectively on the bottom plate.

Description

The high-power thyristor module

The utility model belongs to a kind of basic electronic device, particularly a kind of high-power thyristor module.

The power of high-power thyristor module is big, power consumption is big, and heating is serious, so, in actual use, module must be installed on the custom-designed radiator, to reduce the junction temperature of device.Because the module base areas is big, machining accuracy is limit, and makes the surface produce tens microns unevenness; Equally, the unevenness of the spreader surface that contacts with module is bigger, makes to produce the gap when both contact, even some heat-conducting silicone greases can be filled in the centre, but the thermal resistance of thermal grease conduction has formed so-called contact heat resistance much larger than metal.Because thermal resistance is big, influences radiating effect, cause junction temperature to raise, be operated under the reliable junction temperature for guaranteeing module, must reduce power.Therefore, the power capability that improve module becomes more scabrous problem.On the other hand, the high-power thyristor module needs special radiator in actual use, has both increased use cost, simultaneously, has also increased occupied space.

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and saves the space, reduces cost, good heat dissipation effect and can alleviate power and the high-power thyristor module of the contradiction that junction temperature rises.

Technical solution of the present utility model is: it is made up of shell, electrode assemblie, tube core and base plate, and its special character is that a cavity is arranged in base plate, is separately installed with the water inlet tap and the faucet that communicate with the cavity import and export on base plate.

The utility model has the advantages that:

1, easy to use: as on nozzle and spout, to connect cooling water pipe and get final product, save module and radiator installation process.

2, save the space, reduce cost: base plate is radiator, saves radiator, has saved shared space, has reduced cost.

3, good heat dissipation effect has been alleviated the contradiction that power and junction temperature rise.Because cooling water path is directly to thermal source (tube core), distance is reduced to recently between the two, has saved the contact heat resistance with radiator again, thereby makes thermal resistance be reduced to the raising that minimum, power obtain amplitude peak, and actual effect makes power capability improve nearly 50%.

The drawing explanation:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is an A-A cutaway view among Fig. 1.

Below in conjunction with embodiment the utility model is elaborated:

As shown in the figure, the utility model has a base plate 2 and shell 1, connect by the screw tightening therebetween, a U-shaped cavity 2` is arranged in base plate 2, said cavity 2` advances, outlet 2a, 2b is positioned on base plate 2 sidewalls, advancing, outlet 2a, be welded with the water inlet tap 16 and the faucet 17 that communicate with cavity 2` on the 2b respectively, on base plate 2, be placed with insulating ceramic film 3 successively, public electrode 4, briquetting 5, tube core 6, electrode 9, insulating case 10, plain washer 11 and spring washer 12, spring bearer plate 13, and compress by the screw 14 that passes spring bearer plate 13, said public electrode 4, electrode 9, insulating case 10, plain washer 11 and spring washer 12, spring bearer plate 13 and screw 14 are electrode assemblie, the extreme stroma 7 of control is installed on shell 1 inwall, in shell 1, be marked with silica gel 15, on shell 1, loam cake 8 be installed by screw.

When reality connects, water inlet tap 16 and cooling water pipe are joined, faucet 17 water pipe that runs in gets final product.

Claims

1, a kind of high-power thyristor module is made up of shell, electrode assemblie, tube core and base plate, it is characterized in that, a cavity is arranged in base plate, is separately installed with the water inlet tap and the faucet that communicate with the cavity import and export on base plate.
