Disclose the method for engaging thermal conductor with heat pipe, thermal conductor and the driving machine with the thermal conductor.
Description
Technical field
The present invention relates to method, the bases for engaging thermal conductor with heat pipe of preamble according to claim 1
The thermal conductor of claim 9 and the driving machine according to claim 17 with thermal conductor.
Background technology
From assembly known in the art, the assembly by means of by electro-motor or the driving unit that is formed of pump by hydraulic oil
It is fed to hydraulic system from storage tank.There is load by the hydraulic system that the assembly is supplied(Such as the hydraulic cylinder of toolroom machine)And control
Valve processed.
Due to the efficiency of high power density and the assembly, such assembly must be cooled.This more particularly to electronic horse
It reaches.The overheat of electro-motor must be avoided, and prevents to send out peripheral components, especially hydraulic oil by the electro-motor
Heat.
In order to cool down driving machine or electro-motor, it is known that it is arranged in the lamination or rib of the outside of the shell of machine, and
Heat can be efficiently transferred to ambient enviroment by lamination or rib.The shortcomings that thermal conductor purely streamed by air is, energy
The cooling stream enough obtained is relatively small.It is therefore known in the prior art that regulation transmits heat to the solution on liquid medium.
For example, open file DE 10 2,013 019 728 shows the electro-motor of the end side flange with water cooling, turn
Sub- bearing is arranged in the end side flange.Herein disadvantageously, the housing parts for this water cooling of electro-motor are made
At relatively high cost.The shell of electro-motor is advantageously manufactured from aluminium, and it is rotten that aluminium can suffer from contact in through-flow with water
Erosion.In addition, cumbersome sealing station is arranged on the flange being previously mentioned, these sealing stations are contained risk of leakage and are therefore transported
Row failure risk.
So-called heat pipe or heat pipeline are coolants from the shell of assembly to be cooled or the shell of driving machine to be cooled
Heat transmission and separation effective form, in the heat pipe or heat pipeline, coolant in evaporating area is from object to be cooled
Heat is absorbed, is evaporated, then steam flows into the condensing zone of heat pipe, the thermal output for condensing, and being absorbed there to secondary loop.
Since heat pipe indicates closed system, it is thus eliminated that contact corrosion and the problem of being previously mentioned of sealing.Open file DE 615
382 A1 show the example of this cooling for electro-motor.
It is when using heat pipe it is important that heat pipe and object to be cooled thermally contact, especially with driving machine
The thermo-contact of thermal conductor.In principle, heat pipe is suitable for mechanical compaction, such as in slot.
Therefore, from solution known in the art, in the solution, heat pipe is inserted into enough first
In the slot of open cross-section, and then by the depth direction of slot effective compressional movement be pressed into.Open file US
2011 020 377 3 A1 show such method.The shortcomings that these solutions is that process of press in needs higher indentation
Power, the pressing-in force apply typically only by machine.Therefore higher cost is needed to orient and squeeze involved component.
