Title:
TEMPERATURE CONTROL DEVICE FOR CONCRETE
Document Type and Number:
Japanese Patent JP2022178917
Kind Code:
A
Abstract:
To solve the problem of a conventional temperature control device for concrete that a wick is arranged in a heat pipe and a working fluid is upward moved by a capillary phenomenon so as to make a heat-absorbing characteristic poor.SOLUTION: A temperature control device for concrete includes mainly: a void pipe 12 arranged inside a concrete structure 11; a liquid 13 stored inside the void pipe 12; and a heat pipe 14 inserted into the void pipe 12. The heat pipe 14 is formed with a storage space 23 of a working fluid 24 between an external pipe 21 and an internal pipe 22 without using a wick. With the configuration, the storage space 23 is formed up to the upper side of the heat pipe 14, and the central part of the concrete structure 11 and its peripheral region are actively cooled so as to prevent cracks of the concrete structure 11.SELECTED DRAWING: Figure 1
