6-10min could heat after machine.But electric vehicle does not have an engine, hybrid vehicle to stall when car be also required to supply
It is warm.Electric vehicle generally uses PTC heating systems at present.
Electric vehicle heating ptc heater has wind to warm up two kinds of hot-water heating, and widely used is hot-water heating system.
PTC water-warming heaters using PTC heating elements as fever core, are fabricated to PTC heating tubes, are inserted into dedicated aluminium alloy and lead
By heating and anti-freezing liquid, warm wind is provided via evaporator to car for hot body, and warm wind is soft comfortable, and temperature is stablized moderate, uses peace
Entirely, it is energy-efficient.In addition, PTC water heaters can be additionally used in electric automobile power battery heat management system, pass through heating and anti-freezing liquid
It is heated to battery.
Due to the PTC water-warming heaters that electric vehicle field uses need it is additional automatically controlled to adjust the heating of ptc heater
Power.It is specific as follows：Water temperature is imported and exported by monitoring heater in real time, to judge the heating for needing to increase or reduce heater
Power by adjusting the increase or reduction of controller duty ratio, realizes the heating power of electrodeless adjustment PTC water-warming heaters.
It is adjusted due to automatically controlled by PWM, generally using IGBT as semiconductcor field control from dynamic circuit breaker device.When IBGT devices work
When, the heat of generation can increase chip temperature, if heat dissipation is slow, then be possible to that chip temperature is made to increase above institute
The highest IGBT junction temperatures of permission, the performance of IGBT device will be remarkably decreased, and be unable to steady operation, so as to cause IBGT devices
Penalty or failure；It is general at present using IGBT (being connected with pcb board) be close to the good large plate of thermal conductivity (aluminum metal) into
Row heat dissipation, but since water-warming heater enclosure interior installation space is limited, it is unable to reach good heat dissipation effect.
Utility model content：
Technical problem to be solved in the utility model is to provide a kind of hot-water heating conducive to the heat dissipation of PTC hot-water heating systems
Heater micro-channel heat exchanger, the heat exchanger also preferably realize electric-controlled plate member device while to warm air system heat supply
The heat dissipation of part ensures that automatically controlled board component performance is stablized, and service life is long.
The technical solution of the utility model is to provide a kind of water-warming heater micro-channel heat exchanger, including import
Pipe, outlet, import hydroecium, outlet hydroecium and flat tube, flat tube both ends have been respectively communicated with main leaf, and inlet tube, outlet lead to respectively
Cross import hydroecium, outlet hydroecium connect with the main leaf at flat tube both ends, equipped with heating tube between adjacent flat tube, fixation on import hydroecium
There is a metal large plate of heat transmission, metal large plate upper surface is the plane for being bonded with electric-controlled plate, metal large plate side
Offer the wire casing for wiring.
Using compared with prior art, the utility model has the following advantages after more than structure：This is reasonable in design tight
It gathers, facilitates the wiring of electric-controlled plate, while be easily installed the temperature sensor of monitoring metal large plate temperature, above metal large plate
For plane, increase contact area is conducive to heat dissipation, ensures electric heating apparatus for water warming safe and stable operation.
Preferably, import hydroecium is welded and fixed with metal large plate lower surface.
Preferably, the containing groove for accommodating temperature sensor is additionally provided on metal large plate.
Preferably, the small pressing plate for heat conduction is further fixed on metal large plate.
Further, outlet hydroecium is fixedly arranged above the small pressing plate for heat conduction.
Description of the drawings：
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the vertical view of the utility model.
Fig. 3 is the structure diagram of metal large plate.
Specific embodiment：
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in Figs. 1-3, a kind of water-warming heater micro-channel heat exchanger, including inlet tube 1, outlet 2, import hydroecium
3rd, it exports hydroecium 4 and flat tube 5,5 both ends of flat tube has been respectively communicated with main leaf 6, main leaf 6 is welded and fixed with flat tube 5, inlet tube 1, outlet
Pipe 2 is connected respectively by import hydroecium 3, outlet hydroecium 4 with the main leaf welding at flat tube both ends, and heating is equipped between adjacent flat tube 5
Pipe 6, is welded with the metal large plate 7 for heat dissipation on import hydroecium 3, and 7 lower surface of metal large plate is plane, metal large plate
7 upper surfaces are the plane for being bonded with electric-controlled plate, and 7 side of metal large plate offers the wire casing 8 for wiring, and wire casing 8 is
Curve is set.In use, electric-controlled plate 9 fits in the upper surface of metal large plate.To prevent warm wind heating temperature excessively high, damage electricity
Plate is controlled, the temperature sensor of monitoring temperature need to be set, is additionally provided with to accommodate the accommodating recessed of temperature sensor on metal large plate
