Title:
SELF-EXCITED VIBRATION TYPE HEAT PIPE
Document Type and Number:
Japanese Patent JP2014157007
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a self-excited vibration type heat pipe enhanced in starting characteristics at a low-temperature time.SOLUTION: A self-excited vibration type heat pipe comprises pressure transmission means which is disposed midway of a sealed pipe for transmitting a pressure fluctuation in one-side space to the other-side space. Moreover, the pressure transmission means is given different heat transport characteristics on one side and the other side thereof. The one-side heat pipe (or the first heat pipe) is constituted to have a lower heat transport amount but a more excellent low-temperature responsiveness than those of the other-side heat pipe (or the second heat pipe). The first heat pipe is started earlier in a low-temperature environment than the second heat pipe. Moreover, the vibration of the first heat pipe is transmitted to the second heat pipe by the pressure transmission means. The pressure vibration transmitted induces the self-excited vibration of the second heat pipe so that the self-excited vibration is started earlier than the case of the single second heat pipe.
