Generally, the effect of the inlet manifold configuring cooler in electromotor be make high temperature air flow through cooler after, be cooled to predetermined temperature interval.Its design principle is the centre of the inner chamber that a fin type cooler is placed in inlet manifold, chamber is divided into two independent air chambers, the hot-air of inlet manifold flows through cooler from an air chamber, reduces temperature by the radiating fin of contact cooling device, and the air after cooling enters another air chamber.There is coolant flow the inside of cooler, is taken away the heat of radiating fin by coolant, keeps cooler to be in relatively low temperature all the time, and then ensures that hot-air can continue to be lowered the temperature.
At present, prior art inlet manifold uses external cooler mostly, is assemblied in inlet manifold from outside by cooler by bolt and sealing strip, and in cooler, the water inlet pipe and water outlet pipe of coolant is arranged on cooler top.The deficiency that the prior art exists has: one, the sealing surface between cooler and inlet manifold is excessive, needs arrange a large amount of securing member and coordinate bigger sealing member to meet seal request, and the highest to sealing requirements, manufacturing cost is high；Two, external due to cooler, the heat exchange function of cooler fails to make full use of；Three, the highest due to the sealing requirements between cooler and inlet manifold housing, it is therefore desirable to arranging a large amount of sealing member and be aided with more securing member to meet seal request, causing complicated integral structure, volume is big and weight is big.
Therefore, how to solve above-mentioned the deficiencies in the prior art, become as present invention problem to be researched and solved.
Summary of the invention
It is an object of the invention to provide a kind of cooler built-in and have the motor intake manifold of high leakproofness, to solve, prior art sealing surface is excessive, obturator too much causes the problem that structure is complicated and fails to make full use of cooler heat exchange function.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of cooler is built-in and has the motor intake manifold of high leakproofness, has a housing；Described housing includes upper encloser, lower encioser and coolant pilot cap three part composition；
Wherein, described upper encloser seals structure with described lower encioser by one and is connected, and constitutes and is formed with an assembling chamber between the two, and this assembling chamber is accommodating for the assembling of described cooler, and described assembling chamber is divided into two independent air chambers by this cooler；
Wherein, described coolant pilot cap covers on housing, is connected with described housing seal, constitutes two independent described air chambers airtight；In described coolant pilot cap, water inlet and the outlet of corresponding described cooler are formed with coolant ingress pipe and coolant delivery line, and described coolant ingress pipe is connected with described inlet seal, and described coolant delivery line is tightly connected with described outlet.
Relevant content in technique scheme is explained as follows:
1., in such scheme, described sealing structure is Welding Structure, it is possible to fix for sealing ring fitted bolt, or bonding etc. other seal structures.
2., in such scheme, described cooler uses fin type cooler, it is also possible to be the cooler of other similar principles.
3., in such scheme, the inside of described cooler is communicated with described water inlet and the cooling liquid flowing channel of described outlet.
4. in such scheme, forming airtight air chamber in described housing and between cooler, the hot-air of inlet manifold flows in this sealed gas chamber, is reduced the temperature of air by the radiating fin of contact cooling device.
5., in such scheme, it is tightly connected by Welding Structure between the housing of described coolant pilot cap and described inlet manifold.
6. in such scheme, it is tightly connected by ring structure between described coolant ingress pipe and described water inlet, is tightly connected also through ring structure between described coolant delivery line and described outlet.
Operation principle and the advantage of the present invention are as follows:
A kind of cooler of the present invention is built-in and has the motor intake manifold of high leakproofness, and its housing includes upper encloser, lower encioser and coolant pilot cap, for assembling chamber between upper and lower case, assembles for cooler, and upper and lower case connects by sealing structure；Coolant pilot cap covers on the housing of inlet manifold, reaches and being tightly connected of housing；And the entery and delivery port of corresponding cooler is formed with coolant importing, delivery line in coolant pilot cap, wherein coolant ingress pipe is connected with inlet seal, and coolant delivery line is tightly connected with outlet.Compared to existing technologies, the sealing surface of the present invention is little, cooler heat exchange function can be made full use of, and achieve the high leakproofness requirement between cooler and inlet manifold housing with less part, high leakproofness requirement is met without a large amount of securing members, there is simple in construction, good sealing effect, advantage that heat exchange efficiency is high, and volume is little, lightweight.
