Technical field
The utility model relates to water-cooled radiator, specially a kind of electric vehicle motor controller power module is dissipated with water cooling
Hot device.
Background technique
With flourishing for global economy and technology, energy consumption increases year by year.Currently, the carbon dioxide in the whole world
(CO2) 25% derives from automobile in discharge.There is report to point out, by the year two thousand thirty, global CO2 discharge amount will be once to 42,300,000,000 tons.
In China, the pollution of motor vehicle emission bring has become the principal element in urban atmospheric pollution, and the CO2 discharge in China is current
The whole world the 2nd is occupied, energy-saving and emission-reduction have become the key subjects of car industry development.Therefore, developing new-energy automobile is to realize that energy conservation subtracts
The inevitable Strategic Measure of row and China's automobile industry great-leap-forward and sustainable development.Currently, new-energy automobile industry already becomes
An important ring for China's development strategy.
By the difference of power source, new-energy automobile can be divided into 3 kinds: hybrid vehicle (Hybrid Electric
Vehicle, HEV), pure electric automobile (Electric Vehicle, EV) and fuel cell electric vehicle (Fuel Cell
Electric Vehicle, FCEV).In current various new-energy automobiles, pure electric automobile and hybrid vehicle are new energy
The hot spot of automotive research and development.
Power-driven system is to influence new-energy automobile power performance, the key factor of reliability and cost.Currently, EV and
The high-capacity power module that the core of the power driver of HEV is made of silicon-based power devices, common topological form are
Three-phase two level inverse conversions topology.Electric car uses vehicle mounted dynamic battery group as a source of power, and current battery technology is not
Very mature, capacity density is too low, so electric car manufacturer is intended to car body weight and can gentlier reduce traveling resistance
Power, to improve mileage travelled.Therefore, electric car is increasingly harsh to the volume and weight demands of components.Power driver
As the core drive unit of electric car, it is similarly faced with the requirement of miniaturization and lightweight in this background.Power

Heat；Water-cooling heat radiating device is suitable for the power module of larger capacity, and water-cooled radiator side plate face is mounting surface, and fluid is in water cooling
Heat convection is carried out inside radiator.Air cooling heat radiator efficiency is lower, drives when being applied to the electric car that loss is increasingly promoted
Device, it is meant that need more volume and bigger weight；And water-cooled radiator heat exchange efficiency is high, by reasonable runner design,
It may be implemented to increase heat exchange capacity while small size low weight.
Current water-cooled radiator mostly uses water-cooled plate single side methods for cooling, and inside is mostly the long straight channel of river font or S-shaped
Runner.The general volume of the long straight channel of river font is larger, and river font and S-shaped runner water-cooled radiator uniform temperature are poor, power
Module temperature is unevenly distributed, and under normal circumstances, both can not adapt to high-capacity power mould under electrical automobile driver occasion
The radiating requirements of block.
