Description
Technical field
It the utility model is related to Vehicular charger, and in particular to a kind of heat dissipation structure of Vehicular charger.
Background technology
Vehicular charger refers to be fixedly mounted on the charger on electric automobile, and it is electric automobile power battery to have, peace
Entirely, automatic fully charged ability, the data that charger provides according to battery management system (BMS), dynamic regulation charging current
Or voltage parameter, corresponding action is performed, completes charging process.
The principle of Vehicular charger is to be exported the DC voltage that 220V exchange inputs are converted into needing, to the dynamic of car
Power battery charges.In the course of the work, the switching tube in charger in main current loop can produce substantial amounts of heat, it is necessary to pass through water
Cold or air-cooled form dissipates heat to ensure that whole charger is in safe and reliable working condition.Water cooling is relative to wind
Cold radiating effect is well a lot, therefore most of on the market radiated by water cooling, but for water-cooling pattern, now
The radiating mode of most products is that the big switching tube of heat is poured on water channel to carry out heat conduction, can thus greatly reduce sky
Between utilization rate.
Radiated by the way that metal-oxide-semiconductor is broken into curved be fixed on bottom plate, it is necessary to fall down to be radiated, add whole module
Or the size of casing.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of the problem of improving appeal low space utilization, proposes
A kind of space availability ratio higher solution method, necessary bar is provided so as to optimize in terms of to realize structure and cost
Part..
The utility model is achieved through the following technical solutions：A kind of heat dissipation structure of Vehicular charger, bag
One piece of pcb board is included, and the switching tube being installed on the pcb board, the pin of switching tube are welded on pcb board, the switching tube
Set in a row, be respectively mounted one piece of fin outside it, the back of the switching tube is provided with heat sinking back-plate, the fin with
The heat sinking back-plate at back is locked by the first lock screw and installed, and the fin is inverted to set and carry out contact with water channel and led
Heat.
As preferable technical scheme, the centre of the fin is provided with an arcuate segment, and fin passes through the arch
Section is pressed in the outboard end of switching tube, and is in close contact heat conduction with switching tube.
As preferable technical scheme, the both ends of the heat sinking back-plate are respectively arranged with a lug, are opened up on the lug
There are the fixed screw holes being connected with casing, the second lock screw is installed in fixed screw holes and realized between fin and casing
It is fixedly connected.
Locked and installed by the 3rd lock screw as preferable technical scheme, between the pcb board and heat sinking back-plate.
The beneficial effects of the utility model are：The utility model is simple in construction, by way of being inverted fin, in water cooling
On the basis of the problem of improving space availability ratio, it is more excellent in terms of structure and cost.
