Description
Technical field
The utility model relates to ECU cooling technology field, in particular to a kind of cooling device for ECU.
Background technique
To meet the needs of to big driving power, a large amount of semiconductor power switch has been used inside automobile controller ECU
Device (MOSFET pipe) controls the flowing of power, these power devices can consume electric energy, consumed electric energy meeting at work
Heat is converted to cause the operating temperature of power device to increase, higher operating temperature can be such that the reliability of power device drops
Low, short service life.At present, the thermal design of automobile controller mostly uses greatly heat transfer, free convection and radiation etc. passively to dissipate
Hot mode, while being to meet water proof and dust proof requirement as defined in ISO20653, Seal Design has all been carried out to automobile controller, and it is close
The printed board of small space is encapsulated in because cross-ventilation is unsmooth, it is difficult more to have aggravated heat dissipation.
For the controller of high load capacity, existing design is that heat dissipation design is carried out on ECU shell, i.e., is situated between by cooling
Matter (generally fuel oil or other coolant liquids) carries out forced heat radiation to ECU.Such mode is both needed to when ECU shell is cast, will
Cooling medium circuit is designed on ECU, i.e., ECU shell is hollow.Although such mode radiating efficiency is higher, the casting of shell is given
It makes and improves difficulty, if generating bubble or minute crack in casting process will lead to cooling medium and enter inside ECU, cause
ECU damage, if this situation occurs in the process of moving in vehicle, it will generate serious consequence.Further, since cooling medium has one
Fixed corrosivity, time length may result in interior of shell partial corrosion, equally also will appear the wind that cooling medium enters ECU
Danger.
Summary of the invention
In order to improve the above problem, the utility model provides a kind of ECU cooling device.
Specifically,
The cooling device is made of ECU shell, heat-conducting medium, heat-dissipating pipe, fixed device,
ECU shell is ECU upper casing and/or lower casing, and the ECU shell is provided with thermal trough,
Heat-conducting medium is set in the thermal trough,
The heat-dissipating pipe to match with thermally conductive groove shape is placed on the heat-conducting medium,
The heat-dissipating pipe is fixed in thermal trough by fixed device.
The heat that ECU is generated when working is exported by heat-conducting medium, and is spread by heat-dissipating pipe, to reach cooling ECU
Purpose.The component for playing cooling effect is detachably fixed on the ECU shell by fixed device.When needing replacing or
When person repairs cooling device, fixed device is dismantled.
The technical program has the advantage that
1. detachable design facilitates the replacement and maintenance of radiator, can choose whether to install according to ECU actual conditions
Heat radiation part.
2. the separation design of heat sinking function and ECU shell, so that ECU Shell Manufacture requires to reduce, to reduce
ECU cost.
3. heat-conducting medium is isolated in ECU circuit external, to the corrosion-free hidden danger of sheathing material, prevents cooling medium and enter ECU
Internal and initiation risk.

Specific embodiment
To make implementable this specification, technical solution and the more clear purpose of advantage, below in conjunction with attached drawing, to this theory
Technical solution in bright book embodiment is clearly and completely described, it is clear that described embodiment is this specification a part
Embodiment, instead of all the embodiments.Embodiment based on this specification, those of ordinary skill in the art create no
Property labour under the premise of every other embodiment obtained, belong to this specification protection range.
A kind of ECU cooling device by ECU shell 101, heat-conducting medium 201, heat-dissipating pipe 301, fixed device 401,402,
403,404 composition,
ECU shell 101 is the upper casing of ECU, and the ECU shell 101 is provided with thermal trough 102.The thermal trough 102 is arranged
Route is mainly according to the biggish position that generates heat in ECU.Heat-conducting medium 201 is set in thermal trough 102, and the heat-conducting medium is silica gel
Piece or silica gel grease.Silica gel piece is pasted in thermal trough or coats silica gel grease.The heat generated when ECU being worked by heat-conducting medium
Amount, which transfers out, to be come.The heat-dissipating pipe 301 to match with 102 shape of thermal trough is placed on the heat-conducting medium 201, will be passed by heat-dissipating pipe
Derived heat is further spread.The heat-dissipating pipe 301 is fixed in thermal trough 102 by fixed device.The fixed device
It is made of stop collar 401, fixinig plate 402, fixation hole 403, fixing bolt 404.The stop collar 401 is applied with the heat-dissipating pipe
Patch, 401 side of stop collar extend fixinig plate 402, several fixation holes 403 are arranged on fixinig plate 402, and fixing bolt 404 passes through
Heat-dissipating pipe 301 is fixed on ECU shell by fixation hole 403.When needing replacing or repairing cooling device, fixed device is dismantled
?.The heat that the technical program is generated when ECU works is exported by heat-conducting medium, and is spread by heat-dissipating pipe, to arrive
Up to the purpose of cooling ECU.
One embodiment can only have been gone out in the technical scheme.It to those skilled in the art, can also be by cooling
The lower casing of ECU is arranged in function.Or thermal trough, setting in thermal trough are opened up in lower casing while refrigerating function is arranged in upper casing
Heat-conducting medium is reinforced radiating.Or thermal trough, setting in thermal trough are opened up in upper casing while refrigerating function is arranged in lower casing
Heat-conducting medium is reinforced radiating.
In above-mentioned implementation, fixed device uses face fixed form, it may be assumed that heat-dissipating pipe is exposed slot with stop collar 401
Entire surface carries out application fixation.To those skilled in the art, a fixed form can also be passed through, it may be assumed that only choose heat dissipation
Several points on pipe increase fixing piece in point.The range that the technical program includes should belong in usual replacement means.
