Anti-freezing heat exchanger and water heater

Abstract

The invention relates to an anti-freezing heat exchanger and a water heater. The anti-freezing heat exchanger comprises a heat exchanger body and a water changing pipeline communicating with the heatexchanger body; an anti-freezing pipe wall is arranged on the surface of the water changing pipeline, and an anti-freezing cavity is formed between the anti-freezing pipe wall and the water changing pipeline; an anti-freezing solution is arranged in the anti-freezing cavity; and a heating device is arranged in the anti-freezing cavity. According to the anti-freezing heat exchanger and the water heater, the anti-freezing pipe wall is arranged on the surface of the water changing pipeline of the heat exchanger, the anti-freezing cavity is formed, the anti-freezing solution and the heating deviceare arranged in the anti-freezing cavity, the heating device is arranged to heat the anti-freezing solution, the anti-freezing solution performs heat preservation or heating on the water changing pipeline, the situation that the water heater cannot be normally used due to the fact that water is frozen to block the pipeline occurring in the water changing pipeline caused by a supercooling environment in which the heat exchanger is located is avoided.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to an antifreeze heat exchanger and a water heater. Background technique [0002] A water heater refers to a device that raises the temperature of cold water into hot water within a certain period of time through various physical principles. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, air energy water heaters, heating water heaters, etc. [0003] However, in the northern region, it is very cold in winter, and different types of water heaters often have water pipes that are frozen and cracked to leak water, or the residual water in the pipes freezes and cannot discharge water normally. Contents of the invention [0004] In order to solve the problems existing in the prior art, at least one embodiment of the present invention provides an antifreeze heat exchanger and...
