Heating element, heater heating device, temperature control heater and intelligent heating system

Abstract

The invention relates to a heating element, a heater heating device, a temperature control heater and an intelligent heating system. The heating element comprises at least one set of heating element units, each set of heating element units comprises a hollow central sleeve disposed in a cavity of a heater, a heat-generating wire disposed in a cavity of the central sleeve in a penetrating mode, a filler which fills between the heat-generating wire and the inner wall of the central sleeve and at least one cooling fin connected to the outer wall of the central sleeve, wherein the filler has goodheat conduction and insulation performance; and the total heat dissipation area of the cooling fins is equal to ((0.8-1.6) * watts of required heating power) cm<2>. The heating element, the heater heating device, the temperature control heater and the intelligent heating system overcome the shortcomings that an existing heating element of a warm air heater has low electrothermal conversion efficiency and low heating power, and the advantages being applied in the warm air heater are not obvious; and the proportional relation between the total heat dissipation area and heating watts of the heating element is accurately calculated and designed, and the advantage of high electrothermal conversion efficiency is achieved.

Description

Technical field [0001] The invention relates to a heating element, a heater heating device, a temperature control heater and an intelligent heating system, which are applied in the field of heater production. Background technique [0002] Currently, there are many problems with heaters on the market: [0003] 1. The heating elements of warm air heaters mainly use: PTC heating fins, carbon fiber heating tubes, etc., all of which have various disadvantages: [0004] ①PTC heating fin: It is a corrugated sheet or fin made of aluminum alloy, which is bonded, welded, and molded at high temperature. It has long service life, energy saving, no open flame (no redness), no oxygen consumption, and safety performance High, easy to adjust the heat generation and other advantages. However, PTC materials also have many shortcomings, such as low electrothermal conversion efficiency (86%), large annual power attenuation (with increasing use time, heating power decreases), lead (not environmentally ...

AI Technical Summary

Problems solved by technology

[0011] In order to overcome the disadvantages of low electrothermal conversion efficiency, low heating power, and inconspicuous advantages in application in warm air heaters existing in the heating element of the warm air heater, the present invention provides a heating element. The proportional relationship between the total heat dissipation area and the heating wattage has been accurately calculated and designed, which has the advantage of high electrothermal conversion efficiency

[0012] In order to overcome the shortcomings of existing heaters that directly use metal shells, poor energy gathering effect and hot hands, the invention provides a heating device for heaters, which adopts a metal inner tank, a cylindrical body shell sleeved on the periphery of the metal inner tank, and The insulation cotton filled between the metal liner and the fuselage shell replaces the existing metal shell as the host shell, which not only keeps heat and gathers energy, but also has good heat insulation, which can effectively avoid burns

[0013] In order to overcome the existing shortcomings of being unable to adjust according to the user's surrounding temperature and poor user comfort, the present invention provides a temperature-controlled heater, which senses the real-time temperature around the user by adding a temperature detection device on the remote control, and can pass the The input device and the remote control circuit control the main unit of the heater to achieve the purpose of real-time adjustment of the expected temperature around the user and improve the comfort of the user
