Description
Technical field
The utility model relates to field of electric heating, specifically a kind of multiduty heating air duct.
Background technique
The heating structure of traditional air chute generally has: 1. are arranged single heater in air duct, and this structure, which is common in, to wash the dishes
In machine, although windage is small, contact area is also small, causes heat exchange effect poor, and hot wind performance is unobvious；2. being set in air duct
More heating wires are set, this structure is common in hair dryer, although contact area is big, windage is also big, leads to the wind generated
Amount is few, is not able to satisfy the use demand of user.
Therefore, it is necessary to be further improved.
Utility model content
The purpose of the utility model is to overcome above-mentioned the shortcomings of the prior art, and provide that a kind of design is simple, knot
Structure is reasonable, contact area is big, windage is small, the thermal efficiency is high, low energy consumption, versatility and practical multiduty heating air duct,
It can be applied to the product that hair dryer, dish-washing machine etc. need hot wind to work.
Purpose of the utility model is realized as follows:
A kind of multiduty heating air duct, including air duct ontology；It is characterized by: being provided with one on the air duct ontology
The above heating unit, the heating unit include support plate and thermal component, are provided with heating layer on the single or double of the support plate；
The thermal component is set to the airflow direction on the single or double of support plate and in the ontology of air duct and extends, on thermal component
At least provided with several and not parallel heat dissipation fin of support plate.
The heating unit setting is more than two, and more than two heating units are stacked to be set on the ontology of air duct.
Each support plate compartment is laterally arranged, and each fin compartment that radiates is vertically arranged.
The thermal component is the plates that thermal conductivity is good and thickness is thin, and section is in concave-convex, waveform or zigzag
Deng.
Each heat dissipation fin head and the tail connect.
The thermal component welding is pasted on support plate.
The heating layer is thick film heating body or Electric radiant Heating Film etc..
The beneficial effects of the utility model are as follows:
Reach generation hot wind effect by the way that multiple heating units are arranged in the ontology of air duct, heating unit includes support plate and heat dissipation
Component, support plate are provided with heating layer at least one face, and thermal component is then set on support plate；Heating layer, which is powered, when work sends out
Heat, the heat generated can be transferred directly on thermal component, since thermal component is that airflow direction in the ontology of air duct prolongs
It stretches, so the contact area between air-flow and thermal component increases, and windage reduces, and heat exchange effect is more significant, the thermal efficiency
Not only temperature is up to standard for the hot wind for greatly promoting, therefore generating, and air quantity is big, is able to satisfy the routine use needs of product.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
Referring to figures 1-4, this multiduty heating air duct, including air duct ontology 1,1 inner cavity of air duct ontology are provided with one
The above heating unit A, heating unit A include support plate 2 and thermal component 4, are equipped with heating layer 3 on 2 one side of support plate；Heat dissipation
Component 4 is set to the extension of the airflow direction on 2 another side of support plate and in air duct ontology 1, is integrally formed on thermal component 4
There is several and not parallel heat dissipation fin 401 of support plate 2.3 heating power of heating layer when work, the heat generated can be transmitted directly
To thermal component 4, since thermal component 4 is the airflow direction extension in air duct ontology 1, so air-flow and thermal component 4
Between contact area increase, windage reduce, heat exchange effect is more significant, and the thermal efficiency greatly promotes, thus generate hot wind
Not only temperature is up to standard, and air quantity is big, is able to satisfy the routine use needs of product.
Further, heating unit A setting is more than two, and more than two heating unit A are stacked to be set to air duct sheet
On body 1, according to the actual size of air duct ontology 1 and the heating unit A of use demand setting respective numbers, to meet different need
It wants, therefore versatility and practical.
Further, each 2 compartment of support plate is laterally arranged, and each 401 compartment of fin that radiates is vertically arranged, i.e., support plate 2 with
The fin 401 that radiates is arranged jointly with criss-cross arrangement, the influence between can reducing；By reducing windage, really
Protect air volume；In addition, stacked structure keeps entirety more solid and reliable, structure is more compact, effectively reduces occupied space.
Further, thermal component 4 is the plates that thermal conductivity is good and thickness is thin, can reduce windage；Thermal component 4 is cut
Face is in concave-convex, which can be such that each heat dissipation fin 401 connects from beginning to end, so that thermal component 4 proposes machine-shaping；In view of
