EMBEDDED TYPE HEAT ACCUMULATING TANK

摘要

PROBLEM TO BE SOLVED: To provide an embedded type heat accumulating tank an entire assembly of which can be provided inexpensively and a tank section of which can sufficiently endure an inner pressure (hydraulic pressure). SOLUTION: This tank is comprised of a tank section 10, a lid member 20 capable of opening or closing an upper end opening section 15 and a heat exchanger device 30. The tank section 10 is constituted of a bottomed cylindrical inner layer member 11 made of FRP and an outer layer member 12 made of foamed material laminated outside the inner layer. The inner layer member 11 integrally formed by FRP can perform a sufficient sealing in a safe manner without employing a welding at an entire circumference thereof. The tank section 10 embedded in a pit 6 can prevent deformation or breakage without employing an outer shell by supporting and receiving its load or inner pressure (hydraulic pressure) by a pit forming surface. The lid member 20 is mounted on the pit edge member 7, thereby the upper end opening 15 can be closed without any applying a load of the lid member 20 against the tank section 10.
