Method for designing overheating prevention heat preserving water tank

Abstract

The invention relates to a method for designing an overheating prevention heat preserving water tank. A heat preserving layer is arranged outside an inner container of the water tank; an outer skin of the water tank is coated outside the heat preserving layer; a hollow heat conducting device is also penetrated and embedded into the heat preserving layer, and both sides of the heating conducting device are respectively adhered to the inner container of the water tank and the outer skin of the water tank; and a phase-change material is installed in the heat conducting device, and a phase-change temperature point of the phase-change material is in the overheating protection temperature range of the inner container of the water tank. The method for designing the overheating prevention heat preserving water tank realizes the heat preservation of below a temperature control point and rapid heat radiation of above the temperature control point by the heat conducting device provided with the phase-change material, thereby realizing the heat preservation and overheating prevention of the water tank.

Description

technical field [0001] The invention relates to a design method of a thermal insulation water tank, in particular to a design method of an overheating prevention thermal insulation water tank. Background technique [0002] Electric water heaters, solar water heaters, and solar heating and heating devices have entered the market for many years, among which the heat preservation water tank has always been an important part of the above products. The anti-overheating technology of the thermal insulation water tank is a key technology for product development. [0003] Existing electric water heaters, solar water heaters, and anti-overheating heat preservation water tanks of solar heating and heating devices generally adopt design methods including: (1) using water evaporation in non-pressurized products to prevent overheating; (2) using water in pressure-bearing products The temperature and pressure safety valve (TP valve for short) discharges hot water or steam to prevent over...
