Abstract
Provided is a method for manufacturing a cooling device and a motor housing cooling device manufactured using same, the method including the steps of: making a cooling pipe and forming the cooling pipe to a shape capable of being buried in a housing body; filling the cooling pipe with a support material; making a portion divided from the housing body as a jig body so as to support the cooling pipe against the jib body in an injection mold of the housing body; locating the cooling pipe in the injection mold of the housing body in such a manner as to be supported against the jig body and injection-molding the housing body; and after the injection molding, removing the support material from the cooling pipe.
Claims13
A method for manufacturing a cooling device for circulating a cooling fluid along a cooling pipe, the method comprising the steps of:
- making the cooling pipe and forming the cooling pipe to a shape capable of being buried in a housing body;
- filling the cooling pipe with a support material;
- making a portion divided from the housing body as a jig body so as to support the cooling pipe against the jig body in an injection mold of the housing body;
- locating the cooling pipe in the injection mold of the housing body in such a manner as to be supported against the jig body and injection-molding the housing body;
- and
- after the injection molding, removing the support material from the cooling pipe.
A motor housing cooling device comprising:
- a motor housing having a housing body having an accommodation space formed therein to locate a motor therein and a cover adapted to close the housing body;
- a U-shaped cooling pipe buried in form of zigzag in the housing body in an up and down direction of the housing body in such a manner as to allow a cooling fluid to flow therealong;
- and
- vibration absorbing pipes adapted to absorb vibrations, each vibration absorbing pipe having a pipe-shaped body coupled to a side periphery surface of the U-shaped cooling pipe and a vibration absorbing material filled in the body,
- wherein after the U-shaped cooling pipe is filled with a removable support material and the vibration absorbing pipes are filled with the vibration absorbing material, the U-shaped cooling pipe and the vibration absorbing pipes are located in a housing body injection mold in such a manner as to allow the U-shaped cooling pipe and the vibration absorbing pipes to be supported against a jig body made by dividing a portion of the housing body and to allow the housing body to be molded by means of insert injection molding, and after molding, the support material filled in the U-shaped cooling pipe is removed to provide the housing body where the U-shaped cooling pipe and the vibration absorbing pipes are buried in form of hollow portions,
- so that the motor becomes cool through circulation of the cooling fluid along the U-shaped cooling pipe.
