<P>PROBLEM TO BE SOLVED: To provide an antifreezing device for a tank storage liquid, along with a liquid storage tank with an antifreezing function, capable of performing the heat insulation of the inside of a tank so that storage liquid can be prevented from being freezed in a cold district in winter, of achieving the largely scaled saving of electricity charges with satisfactory availability, and of easily performing the repair or exchange of a heat pipe. <P>SOLUTION: An antifreezing device for storage liquid L is configured of a closed-end heat receiving cylinder 3 buried in the ground with heat transfer property; antifreezing solution 4 stored in the heat transfer cylinder 3; and an annular heat pipe 2 in which an almost U-shaped heat receiving section 22 is arranged so as to be immersed in the antifreezing solution 4, and a heat radiating section 21 is arranged in the liquid storage tank. Furthermore, the annular heat pipe 2 is configured by storing a heat medium liquid 23 in the heat receiving section 22, and by installing an air bubble generation chamber 22a bulging upward below a liquid level S of the heat medium liquid 23 in one vertical pipe of the U-shaped heat receiving section 22. <P>COPYRIGHT: (C)2012,JPO&INPIT |
