Title: Heat transfer device
Inventor: KITAJIMA SOICHI
IPC: F28D15/02
Filed: 1984-09-07
Abstract: PURPOSE:To increase the amount of heat transfer by sharply curtailing the time to stop heating the heat transfer device by a method wherein the upper part of the heating side closed block are made to communicate with each other through a changeover valve. CONSTITUTION:The changeover valve 13 is closed in the initial stage of operation of the heat transfer device and the operating liquid 12 vaporized by the operation of the heating section reaches the heat radiating section through the heat transfer pipe 9. When the quantity of the operating liquid reduces, it is supplied from the closed tank 3 at the heating section through the liquid supply pipe 4. Then, when the supply of the operating liquid exceeds a certain quantity and the level of the liquid lowers, it is detected by a level detecting means and the operation of the heating section is stopped. At the same time, the changeover valve 13 is opened to establish communication between the heating side closed block and the closed tank 10 and the operating liquid pooled in the closed tank returns to the heating side closed tank 3 through a reverse passage. When the liquid level is detected by the upper level detecting means 15, the changeover valve 13 is closed to re-start the operation of the heating section 1.
