Description

Heat pipe and heat exchanger manufacturing method and apparatus equipped with vacuum and working material injection valve device.

Heat pipe is a hollow body and a heat conductive material is inserted into an appropriate amount of working material, and the inside of the container is formed under the atmospheric pressure (condition) (vacuum) and welded and sealed. The working material in the container is a device that transfers heat to the other part of the container (condensation part) at high speed by boiling and phase changing from lower temperature at ordinary atmospheric conditions in the evaporation part. .

The working fluid in the vessel has the heat retained during the phase change process and moves the inside of the vacuum vessel according to the pressure difference in the vessel. A metallic container having excellent thermal conductivity is used to remove heat formed by the movement of the working material in the vessel. The heat transferred to the outside of the vessel and transferred to the outside surface of the vessel will exchange heat with the temperature conditions around it.

The working material in the heat pipe heated in the heating section is boiled in the evaporation section and moved to the condensation section of the lower pressure vessel, then condensed in the inner wall of the lower temperature condensation section and the pressure difference in the vessel And the gravitational field returns to the heating section of the vessel, and this process is circulated repeatedly under vacuum conditions, resulting in rapid heat transfer.

Due to these characteristics, heat pipe has been widely used in general commercial or industrial industry because of its excellent heat transfer performance, and has been widely applied as a heat exchanger for semiconductor cooling, waste heat recovery, and space heating.

In Korean Patent Publication No. 93-5043, in the manufacture of a heat pipe type heat exchanger, a predetermined heat pipe container is manufactured, and then a certain amount of working liquid is first administered to the container, and then the vacuum pump is placed in a vacuum facility. It has been used to operate and inhale and vacuum the air in the container. This method reduces the pressure inside the container according to the amount of time the vacuum pump is running, and vaporizes the working liquid in the container to a low pressure and discharges it out through the vacuum pump. There is a problem that is not exactly known, and the choice of working materials, such as only the solid and liquid materials should be selected in selecting the working materials, there was a limited restriction on the function and role of the heat pipe. In addition, the heat pipe type heat exchangers produced do not form uniform quality conditions among the products.

The present invention relates to the injection of vacuum and working materials to a device for transferring heat in the form of heat pipes, and more particularly, to the vacuum pipes inside the vessel by mounting a vacuum and working material injection valve device, and then injecting the working materials into the heat pipe. The present invention relates to a method of manufacturing a heat pipe, a heat exchanger, and a structure and a method of using the heat exchanger.

The present invention is attached to the valve of the heat pipe type heat exchanger to the valve device required for the injection of vacuum and operating materials to the inside of the container by injecting a constant vacuum composition and the appropriate amount of the operating material through the valve device to uniform heat between the products The present invention provides a method for manufacturing heat pipes and heat exchangers, which can produce heat transfer and heat exchanger products having a transfer performance, and also easily inject gaseous working materials.

In addition, the heat pipe type heat exchanger exchanging the manufacturing heat is proposed to improve the heat transfer function by promoting the phase change of the working material in the evaporation unit by blocking the condensation of the working material generated at the outer diameter of the evaporating sub-pipe. .
