Variable-volume phase-change heat storage water tank

Abstract

The invention discloses a variable-volume phase-change heat storage water tank. A telescopic cavity is defined by a first vertical plate, a second vertical plate, a top telescopic plate and a bottom telescopic plate; each of the top telescopic plate and the bottom telescopic plate is composed of a first connecting plate, a sliding rod and a second connecting plate; a spiral spring is arranged outside each sliding rod; a corrugated liner is arranged in the telescopic cavity; a U-shaped plate is arranged in the corrugated liner; a U-shaped clamping groove is formed in the U-shaped plate, and a phase-change heat storage plate is arranged on the U-shaped clamping groove; the top telescopic plate is provided with a water injection pipe, and the bottom telescopic plate is provided with a water drainage pipe. The first vertical plate is provided with a water supply pipe and a water return pipe. The water tank is wide in application range and suitable for a small water storage place. The volume of the water tank can be flexibly changed, and the water tank is more suitable for power plants, industries and other large water storage places with different heat storage volumes in winter and summer.

Description

technical field [0001] The invention belongs to the technical field of phase change hot water storage tanks, and more specifically relates to a variable volume phase change hot water storage tank. Background technique [0002] A phase change heat storage tank refers to a heat supply tank that uses a certain phase change heat storage material to store temporarily unused or excess heat and release it for use when needed. [0003] In the heating system, in many industrial plants such as smelters and power stations, there is a large amount of high-temperature hot water, but it cannot be used because the temperature is too high or the water quality cannot meet the requirements, and it is directly discharged, causing huge energy waste and phase change. Because of its large heat storage capacity and stable temperature, heat storage materials can absorb heat from high-temperature hot water and maintain the temperature of the heat storage tank at around the phase transition temperatu...
