Description
Technical field
It the utility model is related to electric automobile equipment, and in particular to a kind of cooling system for charging pile radiating.
Background technology
Development of Electric Vehicles was swift and violent in recent years, and the distribution of electric automobile charging pile is also more and more extensive.Charging electric vehicle
At work, circuit board can produce substantial amounts of heat, account for the 5% ~ 6% of charging pile electricity for stake.And with rapid nitriding
Development, the charging capacity of charging pile are also increasing.Therefore, caused heat will be up to several kilowatts even more than ten in charging pile
Individual kilowatt.And the continuous accumulation of heat, the temperature inside whole charging pile can be raised quickly, electricity inside charging pile will be had a strong impact on
The efficient stable operation of road plate, aggravates the aging of electronic component, reduces the charge efficiency of electric automobile, in some instances it may even be possible to fire be present
Hidden danger occur.
Electric automobile charging pile in the market using it is air-cooled directly cool down by the way of radiated, on the one hand due to filling
Heat inside electric stake is bigger, it is necessary to be radiated using multiple small blower fans, on the other hand, air, which enters directly into, to be filled simultaneously
The impurity such as the charging module of electric stake, the dust contained in air, moisture, salinity can be deposited on electronical elements surface, reduce electronics
The radiating efficiency and service life of element.In general, there is cost height, take charging pile inner space in traditional air cooling way
Greatly, the defects of noise is big, service life is short, cooling effect is poor.
Utility model content
The technical problems to be solved in the utility model is that traditional air cooling way has cost height, takes sky inside charging pile
Between it is big, noise is big, service life is short, cooling effect is poor, there is provided it is a kind of it is simple in construction, easy to process, radiating is timely, Temperature Distribution
The uniform cooling system for being used for electric automobile charging pile.
In order to solve the above technical problems, the utility model uses following technical proposals：One kind is used for electric automobile charging pile
Cooling system, including charging module housing, charging module enclosure interior is provided with circuit board and heat pipe, heat pipe outer wall and charging mould
It is immersed between block inner walls filled with conduction oil, the evaporator section of heat pipe in conduction oil, the condensation segment of heat pipe stretches out charging module
Housing is simultaneously connected with charging module case weld.
The evaporator section of the heat pipe is provided with fin I, and the condensation segment of heat pipe is provided with fin II, and fin I length is less than fin
II。
The side of the heat pipe condenser section is provided with radiator fan.
Described conduction oil is insulating heat-conductive oil.
Described circuit board is arranged symmetrically.
The utility model is radiated using heat pipe to charging module housing interior circuit board, is transferred heat to by conduction oil
Taken away after heat pipe, prevent the electric elements of the impact flow circuit board of conduction oil, protection circuit plate；Effectively prevent charging module shell
Body temperature is too high, ensures the efficient stable operation of charging pile internal circuit board；It is simple in construction, easy to process, equipment is ripe can
Lean on, radiating is timely, uniformity of temperature profile and maintains and compares zone of reasonableness.
Brief description of the drawings
Fig. 1 is the utility model main structure diagram；
Fig. 2 is the utility model side structure schematic view.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is paid
The every other embodiment obtained, belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, the utility model includes charging module housing 1, and the inside of charging module housing 1 is provided with circuit
Plate 7 and heat pipe 3, filled with conduction oil 2 between the outer wall of heat pipe 3 and the inwall of charging module housing 1, the evaporator section of heat pipe 3, which is immersed in, leads
In deep fat 2, the condensation segment of heat pipe 3 stretches out charging module housing 1 and is welded to connect with charging module housing 1.The evaporator section of heat pipe
It is arranged in charging module housing, is immersed in conduction oil, can timely takes away and be arranged symmetrically in charging module housing
Heat caused by two circuit boards.The heat that heat pipe is taken away scatters and disappears in atmosphere in condensation segment.Conduction oil 2 is in charging module housing
Conductive force is played in 1, the heat that circuit board 7 is sent is conducted interior to heat pipe 3 and takes charging module housing 1 out of by conduction oil 2；Lead
Deep fat functions only as heat transfer effect in charging module housing 1, does not flow, and prevents conduction oil flowing to charging module housing
Electronic component in 1 produces impact, prevents from damaging electronic component, extends the service life of charging pile.Charging module housing 1 seals
Set, heat pipe 3 is welded to connect with charging module housing 1, prevents conduction oil from revealing.
The evaporator section of the heat pipe 3 is provided with fin I4, and the condensation segment of heat pipe 3 is provided with fin II5, and fin I4 length is small
In fin II5.Fin I4 is arranged on inside charging module housing 1, is limited by space, and fin I4 length is smaller.Fin I4 and
The heat transfer area of fin II5 setting increase heat pipe, heat-transfer effect are good.
The side of the condensation segment of heat pipe 3 is provided with radiator fan 6.Radiator fan 6 is arranged on the side of condensation segment, opposite heat tube
Blowing, strengthen radiating, accelerate the condensation of condensation segment, increase radiating efficiency.
Described conduction oil 2 is insulating heat-conductive oil.Prevent that short circuit occurs in charging module housing 1.
Described circuit board 7 is arranged symmetrically.Heat caused by the circuit board 7 being arranged symmetrically is more uniform, beneficial to heat exchange.
