Water heater for accumulating heat at constant pressure

Abstract

The invention relates to a water heater, in particular to a water heater for accumulating heat at constant pressure. The water heater comprises a water tank, a heating device and a copper aluminum water pipe, wherein the water tank is used for being heated and accumulating heat, and the copper aluminum water pipe is coiled in the water tank. The water heater for accumulating heat at the constant pressure is characterized in that the water tank for being heated and accumulating heat and the water pipe coiled in the water tank independently circulate respectively; the heating device is used for heating water in the water tank for being heated and accumulating heat; water flow carries out heat exchange for heating through the water pipe coiled in the water tank; and the atmosphere constant pressure in the water tank for being heated and accumulating heat has no pressure load. The water heater has the advantages that the shape limitation of the water tank for heating and accumulating heat is overcome without bursting danger, and particularly, the shape of a domestic water heater can be designed arbitrarily. A plurality of water pipes coiled in the water tank can be arranged in the water tank for being heated and accumulating heat, and the water heater has multiple purposes, such as drinking water, bath water, heating water and the like.

Description

technical field [0001] The invention relates to a water heater, in particular to a water heater with normal pressure heat storage. Background technique [0002] The water heater currently used is heated by the water flow through the heating water storage tank, and the heating water storage tank is under the pressure of the water flow. The pressure heating water storage tank is in danger of bursting, and the strength requirement limits the shape of the heating water storage tank, especially for household use. The shape and heating efficiency of the water heater. The hot water flow of the normal-pressure water heater must be continuously and repeatedly pressurized, which increases the power load. Contents of the invention [0003] The technical problem to be solved by the present invention is: the water flow is heated by the heated water storage tank, the heated water storage tank bears the pressure of the water flow, the pressure heated water storage tank is in danger of b...

[0002] The water heater currently used is heated by the water flow through the heating water storage tank, and the heating water storage tank is under the pressure of the water flow. The pressure heating water storage tank is in danger of bursting, and the strength requirement limits the shape of the heating water storage tank, especially for household use. The shape and heating efficiency of the water heater

The hot water flow of the normal pressure water heater, after heating, the pressure releases and returns to the normal pressure water heater, which must be repeatedly pressurized, which increases the power load
