Description
Technical field
The invention belongs to the thermal component technical field of power part, specifically a kind of motor coldplate, for improving the radiating efficiency of motor.
Background technology
Motor is a kind of conventional rotary electric machine converting electrical energy into mechanical energy.Lathe, water pump, need motor to drive；Electric locomotive, elevator, need motor to draw.Electric fan in family life, refrigerator, washing machine, the most various motor toys all be unable to do without motor.Motor has been applied in the various aspects in modern society's life.Motor, in use due to the existence of various losses, makes temperature constantly raise, and in order to normally use, cooling is even more important.As can not be well it cooled down, the service life of motor can be affected.If the heat-sinking capability of motor is poor, then motor temperature can be caused too high, the service life of motor can be affected, cause the problems such as deadlock, the life security of operator time serious, can be threatened.
Traditional motor realizes heat radiation generally by installing coldplate in motor surfaces, and the coldplate in the big motor surfaces of heat dissipation capacity is internally provided with cavity, increases radiating efficiency by circulating cooling liquid in cavity.Cavity size within existing coldplate is usually fixing, heat radiation can only be accelerated by the speed that coolant in acceleration cavity is passed through, and due to the restriction of the speed of heat exchange between coolant and coldplate, accelerate coolant flow and still there is certain limitation, therefore the cavity volume of coldplate can only be done more and realize preferably dispelling the heat, and the excessive meeting of coldplate volume brings the biggest difficulty in transport carrying, and motor is not the running of moment high power, the most excessive coldplate is being the most all waste.
Summary of the invention
The present invention is directed to prior art not enough, it is provided that a kind of convenient transport, cavity volume is sized to the motor coldplate regulated voluntarily according to temperature.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals: a kind of motor coldplate, including panel and flanging, the inner side on two length of side limits of the upper surface of described panel has respectively been evenly arranged several circular indents along long limit, on the described panel between the two circular indents of row, uniformly interlaced arrangement has several geometry indents, the both sides of described panel connect straight down flanging, parallel with long limit on described flanging centrally arranged have a U-shaped groove, described panels outside is provided with shell, described shell forms cavity with described panel, described shell two ends are provided with some medium through hole, the one side that described shell is relative with described panel is soft sealant, lean between described soft sealant and described panel and be provided with some air bag posts.
Preferably, it is plane bottom described circular indent and is divergent shape by bottom to opening.Circle indent and motor are fitted, and is arranged to divergent shape and makes the heat of motor can quickly be conducted to panel, and quickly have quick heat radiating in the circular indent of divergent shape.
Preferably, described geometry indent be shaped as ellipse or water-drop-shaped or rhombus.
Preferably, the size of described panel and the quantity of geometry indent match with the volume size of motor.
Preferably, described panel end is provided with connecting plate, described connecting plate is provided with and coordinates the through hole installed with motor.Connecting plate is set for installing fixing by panel and motor.
Preferably, described soft sealant is rubber layer.
Preferably, described soft sealant is nylon inner lining rubber layer.
nullThe present invention is compared with prior art，Have the advantages that the present invention is when electric motor operation，Air is sent in the gap between panel and motor by air-supply arrangement，Body is cooled down，Axially there is many geometry indents due to panel inner wall in the air of flowing in flow process，Air flowing produces a certain degree of disturbance and forms irregular whirlpool district，And cool down the holdup time that can increase cooling air after air forms turbulent flow or whirlpool in heat radiation gap，The cavity that panel and shell are formed is passed through the working medias such as cooling water by medium through hole，Working media flows in the cavities，Panel distributes heat in the middle of working media，When panel temperature raises，The soft sealant of gas expansion lifting in air bag post，The volume making cavity increases can store the coolant that energy is many，Make heat exchange between coolant and panel more abundant，So that heat exchange efficiency improves，And small volume convenient transport when this coldplate does not uses at normal temperatures.

Detailed description of the invention
nullWith detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings: see Fig. 1 to Fig. 5，A kind of motor coldplate，Including panel 1 and flanging 5，The inner side on two length of side limits of the upper surface of described panel 1 has respectively been evenly arranged several circular indents 4 along long limit，On the described panel 1 between the two circular indents 4 of row, uniformly interlaced arrangement has several geometry indents 3，The both sides of described panel 1 connect straight down flanging 5，Parallel with long limit on described flanging 5 centrally arranged have a U-shaped groove 2，It is provided with shell 8 outside described panel 1，Described shell 8 forms cavity 9 with described panel 1，Described shell 8 two ends are provided with some medium through hole 10，The one side that described shell 8 is relative with described panel 1 is soft sealant 81，Lean between described soft sealant 81 and described panel 1 and be provided with some air bag posts 11，In the present embodiment，Described soft sealant 81 is rubber layer or nylon inner lining rubber layer.It is plane bottom described circular indent 4 and is divergent shape by bottom to opening.Described geometry indent 3 be shaped as ellipse or water-drop-shaped or rhombus.The size of described panel 1 and the quantity of geometry indent 3 match with the volume size of motor.Described panel 1 end is provided with connecting plate 6, described connecting plate 6 is provided with and coordinates the through hole 7 installed with motor.
Described heat radiation cooling device is arranged on the shell surrounding of motor, during electric motor operation, air is sent in the gap between panel and motor by air-supply arrangement, body is cooled down, axially there is many geometry indents 3 due to panel 1 inwall in the air of flowing in flow process, air flowing produces a certain degree of disturbance and forms irregular whirlpool district, and cool down the holdup time that can increase cooling air after air forms turbulent flow or whirlpool in heat radiation gap, the cavity 9 that panel 1 and shell 8 are formed is passed through the working media such as hydraulic oil or cooling water by medium through hole 10, working media flows in cavity 9, shell 8 distributes heat in the middle of working media.Owing to working media is constantly in flow regime in system work process, and when the flow direction of two kinds of cooling mediums is contrary, heat transfer effect is best, so the heat dispersion of motor can improve a lot.The gas in air bag post 11 can be heated when motor temperature persistently rises, gas expansion air bag post 11 is made to extend the soft sealant of lifting 81, so that the volume of cavity 9 becomes big, make heat exchange between coolant and panel 1 more abundant, so that heat exchange efficiency improves, and air bag extends the most completely when this coldplate does not uses at normal temperatures, the convenient transport of small volume.
