Heat transport device

Abstract

A heat transport device includes a container having a hollow structure in which a fluid channel is formed, at least one each thermal-receiver-type heat exchanger and thermal-radiator-type heat exchanger arranged side by side on an outer wall of the container along the fluid channel, and driving heat exchangers provided at both terminal portions of the container. In this heat transport device, both ends of the fluid channel are closed to prevent intrusion of external air, and a liquid and gas are sealed in the fluid channel. The driving heat exchangers cause the liquid to oscillate in the container along its fluid channel. The heat transport device provides low acoustic noise performance and improved temperature controllability, high heat transportation and heat radiating capacities, as well as improved heat transfer and fluid flow characteristics.

What is claimed is:  
     
         1 . A heat transport device comprising: 
 a container having a hollow structure in which a fluid channel is formed, both ends of the fluid channel being closed to prevent intrusion of external air, and a liquid and gas being sealed in the fluid channel;    at least one each thermal-receiver-type heat exchanger and thermal-radiator-type heat exchanger arranged on an outer wall of the container along the fluid channel; and    driving heat exchangers provided at both terminal portions of the container for causing said liquid to oscillate along the fluid channel.    
     
     
         2 . The heat transport device according to  claim 1 , wherein the internal volume of each terminal portion of the container where the driving heat exchanger is provided is equal to or larger than the internal volume of that portion of the container which is bounded by the center of the thermal-receiver-type heat exchanger and the center of the thermal-radiator-type heat exchanger.  
     
     
         3 . The heat transport device according to  claim 1 , wherein said liquid is a combination of two types of liquids having different boiling points.  
     
     
         4 . The heat transport device according to  claim 1 , wherein each terminal portion of the container where the driving heat exchanger is provided is formed into a double pipe structure.  
     
     
         5 . The heat transport device according to  claim 1 , wherein a porous element which produces capillary action is fitted inside at least one of the terminal portions of the container where the driving heat exchangers are provided.  
     
     
         6 . The heat transport device according to  claim 1 , wherein means serving as a nucleus for bubble formation is provided in at least one of the terminal portions of the container where the driving heat exchangers are provided.  
     
     
         7 . The heat transport device according to  claim 1 , wherein said fluid channel in which the liquid flows is a meandering fluid channel.  
     
     
         8 . The heat transport device according to  claim 7 , wherein adjacent portions of the wall of the meandering fluid channel are united, together forming a single structure.  
     
     
         9 . The heat transport device according to  claim 7 , wherein the driving heat exchangers are formed of a Peltier element, and wherein the terminal portions of the container are joined to each other via the Peltier element.
