To the index of flow specification.
Battery pack in electric automobile needs heat management device（Heat exchanger）To ensure their performance, durability and safety
Property.Performance can suffer damage at low temperature, and durability can suffer damage at high temperature.
Chinese patent：CN204142045U, a kind of heat exchanger is disclosed, including
First liquid room and the second liquid room；Connect multiple flat siphunculus of the first liquid room and the second liquid room；
Shell, the shell surround the multiple flat siphunculus from surrounding, and the shell, the first liquid room and the second liquid room are formed
One closing space, the multiple flat siphunculus are located in the closing space.
High-pressure side first medium flows through the passage being made up of two liquid rooms and flat siphunculus, and low-pressure side second medium is flowed through by outer
The closing space that shell and two liquid rooms are formed, first medium are carried out with second medium by flat siphunculus tube wall and two liquid room side walls
Heat exchange, simple in construction, flat siphunculus can effectively increase the compressive resistance of product, and the variation of circulation passage pattern, can
Any adjustment circulating channel structure is actually needed with basis, to adapt to the needs of various products.
The hot channel of prior art（Flat siphunculus）Connected mode with liquid room is welding, and both are vertical connection, vertically
The shortcomings that connection be exactly solder side very little, can so easily lead to leak.
The content of the invention
In order to overcome the shortcomings of background technology, the present invention provides a kind of mouth organ passage parallel flow heat exchanger hydroecium connection knot
Structure, it is few mainly to solve hot channel and the hydroecium solder side of existing electric automobile heat exchanger, the problem of easily leakage.
The technical solution adopted in the present invention is：A kind of new connection of the hot channel and hydroecium of electric automobile heat exchanger
Hot channel between structure, including upper tank, lower header, and two hydroeciums, described upper and lower hydroecium are pancake, upper,
Lower header upper surface is designed with several symmetrical connecting holes；Described hot channel is also pancake, and both sides are elbow knot
Structure, described elbow are inserted in connecting hole, and the elbow is to work in coordination with connecting hole；Described hot channel is under elbow
Surface, it is bonded with the upper surface of hydroecium.
Further, described connecting hole inside edge is rounding corner structure, the elbow junction of described hot channel
For corresponding rounding corner structure.
Further, described elbow structure and hot channel are 90 °.
Further, described hot channel is multi-channel pipeline, and the hot channel section is flat mouth organ shape.
Further, described upper and lower hydroecium all includes upper lid and lower cover, described upper lid medial surface and upper outer side of lid face
Fitting.
Further, described connecting hole is arranged on lid, and described lower cover bottom is provided with several flow-disturbings hole.
The beneficial effects of the invention are as follows：Compared to the more original vertical connection face of weld, solder side of the present invention is far longer than existing
, such effect is can be more firm, it is not easy to leaks.Using NOCOLOK solderings, welding quality is good, structure
Reliably；From refrigerant as medium, the cooling system of electric car is simplified.

Embodiment
Embodiments of the present invention is further illustrated below in conjunction with the accompanying drawings：
As Figure 1-Figure 4, the new Joining Structure of a kind of hot channel of electric automobile heat exchanger and hydroecium, including it is upper
Hot channel 3 between hydroecium 1, lower header 2, and two hydroeciums, it is characterised in that：Described upper 1, lower header 2 is flat
Shape, upper 1, the upper surface of lower header 2 be designed with several symmetrical connecting holes 4；Described hot channel 3 is also pancake, and two
Side is elbow structure 5, and described elbow 5 is inserted in connecting hole 4, and the elbow 5 is to work in coordination with connecting hole 4；Described radiating
Pipeline 3 is bonded close to the lower surface of elbow 5 with the upper surface of hydroecium.
The innovative point of the present invention is solve the hot channel 3 and hydroecium solder side of existing electric automobile heat exchanger
It is few, the problem of easily leakage.The structure being connected by elbow 5 with hydroecium, increases solder side.Specially connecting hole 4 is arranged to
With 3 two sections of 5 suitable size of elbow of hot channel, when assembling, elbow 5 is fitted into connecting hole 4, in connecting hole 4
Edge welding, this is solder side at first；Because pancake hot channel 3 is bonded with pancake hydroecium upper surface,
Also welded at both junction edges, this is solder side at second；The solder side that both add up is far longer than existing weldering
Junction so that more firmly, avoid the occurrence of the phenomenon of leakage.
The described inside edge of connecting hole 4 is rounding corner structure, and the junction of elbow 5 of described hot channel 3 is relative
The rounding corner structure answered.
Described elbow structure 5 is 90 ° with hot channel 3.The present invention is preferably 90 ° of angle, this angle another
Effect is exactly readily to assemble, meanwhile, best heat transfer effect can be played.
Described hot channel 3 is multi-channel pipeline, and the section of hot channel 3 is flat mouth organ shape.It may be noted that
It is that the hot channel 3 of mouth organ shape is not equivalent to combine with existing multiple flat tubes, those skilled in that art can not letter
Single hot channel from multiple flat tube kick-off lyrates.Those skilled in that art can be used as radiating tube with flat tube
Road, and applicant has paid prolonged creative work, final design has gone out the hot channel of the mouth organ shape.
The hot channel 3 of mouth organ shape is for multiple flat tubes, and rate of heat exchange is higher first, it is assumed that to reach ten
The effect of flat tube mutually arranged side by side, the hot channel 3 of mouth organ shape need to open ten mouth organ holes in single hot channel 3,
Heat exchanger effectiveness is higher, can be significantly higher than the stream not shunted into several tiny tributaries, heat exchanger effectiveness fluid partitioning
Body.
Secondly, identical heat exchange effect is reached, the materials of hot channel 3 of mouth organ shape are more saved, can greatly saved into
This, and structure can be more simple, is easily assembled.
The material of described hot channel 3 is preferably ENAW-3003, and surface is without composite bed.The pipeline of the material is adapted to add
Work, it is easy to the shaping of mouth organ shape, while material is lighter, alleviates the weight of whole heat exchanger.
Described hot channel 3 is single, is because to be bonded with battery surface.Single mouth organ shape hot channel 3 is led
The effect wanted is also under identical heat exchanger effectiveness, and single to realize that structure is simpler, cost is lower, meanwhile, quality is more
Light effect.
The altitude range of the bore of hot channel 3 is 1 ~ 5mm, and width range is 30 ~ 80mm.The height and the width are with scattered
Hot device specification and change.
Described upper 1, lower header 2 all includes upper lid 6 and lower cover 7, and the described medial surface of upper lid 6 pastes with the lateral surface of lower cover 7
Close.
Described connecting hole 4 is arranged on lid 6, and the described bottom of lower cover 7 is provided with several flow-disturbings hole 8.Flow-disturbing hole 8
Effect be increase fluid resistance, so as to add the efficiency of heat exchange, flow-disturbing hole 8 can be the projections of roundlet cylindricality, can also
It is the projection of other arbitrary shapes, the present invention preferably roundlet cylindricality.Certainly, the arrangement mode in flow-disturbing hole 8 arranges for uniform intervals,
For spacing between 11.6mm-12.6mm, this spacing can reach maximum heat exchange efficiency.
Every technical staff's notice：Although the present invention describes according to above-mentioned embodiment, of the invention
Invention thought be not limited to that invention, any repacking with inventive concept, will all include this patent protection of the patent right
In the range of.
