Heater

Abstract

A heating apparatus comprises a casing and a heat generation element, the heat generation element being located inside the casing, the casing comprising two layers: an inner layer casing and an outer layer casing, the inner layer casing and the outer layer casing being joined tightly, the inner layer casing using tubing having desirable thermal conductivity, and the outer layer casing using tubing that is rust resistant. The inner layer casing uses tubing having desirable thermal conductivity, so as to transfer heat generated by the heat generation element to the outer layer casing in time and thoroughly, thereby improving thermal conduction efficiency and thermal energy utilization, and extending the service life of the heat generation element. The outer layer casing uses tubing that is rust resistant, and is not easily oxidized from high temperature and contact with water, thereby extending the service life of the heating apparatus. When the inner layer casing uses an aluminum tube, and the outer layer casing uses a stainless steel tube, because of the existence of the stainless steel tube, the aluminum tube does not crack, so that the production process of the heating apparatus is simple, and the service life is long.

Description

technical field [0001] The invention relates to a heating device, in particular to a heating device with simple production process, high heat utilization efficiency and long service life. Background technique [0002] Existing heating devices generally have a relatively short service life. There are two reasons: one reason is that due to poor thermal conductivity, the heat generated by the heating element cannot be conducted in a timely and sufficient manner, thereby shortening the service life of the heat conducting element, thereby shortening the entire life of the heating element. The service life of the heating device; another reason is that the pipes in contact with water are prone to rust and corrosion due to high temperature, thereby shortening the service life of the entire heating device. Contents of the invention [0003] Based on the deficiencies of the prior art, the purpose of the invention is to provide a heating device with simple production process, high he...
