Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Shown in Fig. 1, Fig. 2, Fig. 3.A kind of cooling and sealing structure of electric machine controller of the present invention includes cooling water channel body, tank
Lid and sealing shroud.Cooling water channel body includes the tank of both sides distribution, wherein, side tank includes the connected water inlet saliva of 7- second
Groove, 6- U-typeds cooling bath and 8- the second delivery port tanks；Opposite side tank includes connected the first water inlets of 3- tank, 5-
IGBT cools down water layer and 4- the first delivery port tanks, 8- the second delivery port tanks are connected with 3- the first water inlet tanks.2- tanks
Lid is plane cover plate, and the both sides tank of sink cover and cooling water channel body complements each other to form complete cooling water channel, sink cover
For steel sink cover.1- sealing shrouds are plane grommet type seals, identical with sink cover shape, and use glue sticking shape on sink cover
Integrally, sealing shroud uses silicon rubber.Present invention improves over sealing means, eliminate special seal groove structure and addition is close
The process of the encapsulants such as seal, encapsulant and water channel lid are made of one formula., only need to be according to installation water channel lid during installation
General step, one body swimming groove lid use compression bonding method with cooling water channel body, integral sealing are realized by uniformly reinforcing.It is close
Closure material is in close contact with whole tank, has reached better seal effect compared to ring structure.Without being loaded on water channel
Encapsulant, reduce the difficulty of installation procedure.Encapsulant is changed to sealing film by sealing ring（It is made of one with sink cover
Sealing structure）The service life of sealing structure is added afterwards.U-typed cooling bath is the U-shaped revolution that two U-type grooves are formed by connecting
Cooling bath, positioned at the motor controller casing bottom with electric capacity face, the i.e. cooling water channel corresponding with electric machine controller electric capacity
The folding corner region of body.The port of second water inlet tank and the second delivery port tank is located at the central region of cooling water channel body.
IGBT cooling water layers are positioned at the motor controller casing bottom with IGBT pipe faces, i.e., corresponding with IGBT pipes on cooling water channel body
Region, the first water inlet tank is located at adjacent cooling water channel body central region in the middle part of IGBT cooling water layers.
Present invention improves over traditional sandwich cooling by water mode, using two-sided cooling arrangement.Second water inlet
Tank is connected with U-typed cooling bath one end, and the U-typed cooling bath other end is connected with second delivery port tank one end, the second water outlet
The saliva groove other end is connected with IGBT cooling water layer entrance points, and the IGBT cooling water layer ports of export are connected with the first delivery port tank,
Coolant flows through U-typed cooling bath, the second delivery port tank, first successively by external cooling pipe by the second water inlet tank
Water inlet tank, IGBT cooling water layers, last coolant is flowed out by the first delivery port tank by external outlet pipe, thus is had
Longer runner and larger area of dissipation, the radiating time is also increased, recirculated water is cooled down electricity by U-typed cooling bath first
Machine controller electric capacity, the operating temperature of electric capacity is lower than IGBT, cools down water layer subsequently into IGBT, improves system radiating efficiency.
The IGBT cooling water layers that the present invention is diagonally designed using monoblock type flat structure and water channel gateway, thus can full model
The cooling effect that cooling ensures IGBT pipes is enclosed, and can reduces volume, convenient installation in manufacture craft.The present invention as a result of
The U-typed cooling bath of back-shaped water channel, so that when current flow through controller box, area of dissipation increase, the length of U-typed cooling bath
Degree design is calculated according to the area of dissipation of electric capacity, can be good at ensureing the cooling of electric capacity so that radiating effect strengthens.This hair
Bright to be attached the line space design of screw according to sealing shroud and seal groove contact area, and water flow pressure and temperature, optimization is close
Envelope connection, realize that equal strength seals.
