Abstract
The invention discloses a hot plate cooler for a wind power generation insulated gate bipolar transistor (IGBT) converter power module, which comprises an aluminum substrate, hot plates, radiating fins and a wind scooper, wherein all the parts are assembled together by bolts; and the heat of the aluminum substrate is transferred to the radiating fins by the hot plates, and is dissipated in an air cooling way. The hot plate cooler has the advantages that: 1) the hot plates can uniformly transfer a heat flow with non-uniform density produced by the IGBT converter power module on the back of the aluminum substrate to the radiating fins on the other sides of the hot plates by the peculiar performance of the hot plates to ensure a good radiating effect; 2) the side effect of cantilever stress is avoided by adopting the hot plates to transfer the heat; and 3) the hot plate cooler has a small volume, the total height of the hot plates and the radiating fins is reduced by 84 percent compared with the height of a radiator adopting a hot pipe structure, and the compact structure also satisfies the needs of users.
Description
Technical field
The present invention relates to a kind of wind power generation IGBT unsteady flow power model cooler, specifically a kind of hot plate type cooler.
Background technology
IGBT unsteady flow power model in wind power generation all is fixed on the metal substrate usually, because the power difference, therefore the density of heat flow rate that produces just has very big-difference.The heat that produces sees through substrate, is taken away by the radiator of substrate opposite side.Now common to directly being fixed in the substrate opposite side with radiating fin, the heat that IGBT unsteady flow power model is produced loses by air cooling way.Because the density of heat flow rate difference that IGBT unsteady flow power model produces, thereby radiating effect is unsatisfactory.
The radiator that also has has utilized hot pipe technique, is about to the heat pipe tube bank and takes root in aluminium base, and the heat delivered that the electric elements on the aluminium base are distributed is taken away heat by air cooling way to the condensation segment of heat pipe again.Although heat pipe is described as the superconductor of heat in the heat exchange field, but the mode that adopts heat pipe to take root, every heat pipe and aluminium base contact-making surface also have only the area of bore, and heating surface (area) (HS is limited relatively, therefore need a lot of heat pipes.Because heat pipe is longer, the entire radiator volume is bigger again.Heat-pipe type radiator also exists because of IGBT unsteady flow power model generation density of heat flow rate difference, the unfavorable situation of radiating effect.In addition because of aluminium base is vertical arrangement, so the heat pipe tube bank is cantilever position and arranges that heat pipe and aluminium base connecting portion stress are bigger, and reliability is had considerable influence.
Summary of the invention
What the present invention will solve is the above-mentioned defective that prior art exists, and aims to provide a kind of hot plate type radiator.
The technical scheme that addresses the above problem employing is: a kind of wind power generation IGBT unsteady flow power model hot plate type cooler, comprise aluminium base, hot plate, radiating fin and wind scooper, by bolt together with each component-assembled, the heat of aluminium base passes to radiating fin by hot plate, loses by air cooling way again.
According to the present invention, the hot plate size is wanted the heat dissipation region of aluminium coating substrate back electric elements.
According to the present invention, radiating fin is identical with the hot plate area.
According to the present invention, a radiating fin and a hot plate constitute a heat-sink unit, and one or more heat-sink units are disposed on the described aluminium base, and a total wind scooper is set on it.
According to the present invention, described hot plate metal material is a copper, and interior media is a water.Can operate as normal for ensureing in-40 ℃ even lower environment, in the hot plate medium, be added with 60～80 purpose water smoke copper powders.
According to the present invention, the radiating fin material is an aluminium, and space width is 4mm, and fin height is 40～50mm, and fin top width degree is 1.5mm, and wing root width is 2.5mm, and the fin substrate thickness is 5mm.
According to the present invention, the position flatness of aluminium base, hot plate and radiating fin contact-making surface requires to be no more than 0.5, and the contact-making surface face applies with heat-conducting glue, is assembled together with bolt again.
Advantage of the present invention:
1) the uneven density of heat flow rate that adopts the hot plate mode aluminium base back side IGBT unsteady flow power model can be produced by the distinctive performance of hot plate, passes to the radiating fin of hot plate opposite side equably, has ensured better heat radiating effect.
2) adopt the hot plate structure to transmit heat, the side effect of no cantilever stress.
3) volume is little, and hot plate adds that the height of radiating fin compares with the radiator of heat pipe structure, and volume has reduced 84%.Compact structure also meets user's requirement.
