Description

Motor cooling apparatus by water cooling

The present invention relates to a water-cooled cooling motor, and more particularly, a fluid-circulating water-cooled motor cooling by casting a housing case of stainless steel and dissimilar metals in which a stainless pipe is embedded in the housing case to circulate the fluid to cool the motor. Relates to a device.

In general, the heat generated during the driving of the motor acts as a factor to lower the driving efficiency of the motor, there is a motor cooling method using the air-cooled or water-cooled to prevent this.

Air-cooled motors are most commonly used in such a way that they extend to the rotor of the motor and the fan is a device to force circulation of the air to cool the housing case. This method is simple to install, but the motor becomes larger and noises as much as the space occupied by the fan mount.

Since water-cooled motors are not equipped with fans, they can be freely selected for the motor's external dimensions and have no noise. However, special methods are required to maintain fluid tightness.

An example of the air-cooled or water-cooled motor cooling device will be described with reference to FIGS. 6 and 7.

6 shows a special device in the coupling portion 62 to maintain the airtightness of the fluid in the existing housing case, such as welding or impregnating the housing case to prevent flooding of the cooling fluid (cf) to the inner wall (64). In the case where the brass pipe 72 or the like is directly banded to the outer wall 74 of the housing case 70 in the existing housing case as shown in FIG. 7, the heat transfer is applied to the cover 76 of the housing case. The contact area becomes a line and the heat transfer efficiency is lowered because the fluid of the pipe absorbs the heat released from the housing case outer wall 74. In addition, the bending of the pipe in the manufacture of this cooling device has to be worked correctly on the dimensions of the housing case 76, there is a problem that the cost increases because it requires an additional process.

Thus, the present invention was devised to solve the above problems, the present invention is to prevent the leakage of fluid in advance by using a stainless pipe, and the banding of the pipe can be made by the housing case is easy to manufacture and easy cost It is an object of the present invention to provide a fluid circulating water-cooled motor cooling apparatus by casting a housing case of a lowered stainless pipe and dissimilar metal.
