Abstract
The utility model discloses an electric heating device used on a warm air heater, which comprises more than one substrate which is longitudinally arranged between an air inlet and an air outlet of the warm air heater, a plurality of through holes are arranged in the longitudinal direction of the substrate, and each through hole is connected with an electric heating wire in a through way; the design completely depends on the realization of natural heat convection and heat exchange when indoor air passes through the electric heating device, and can realize automatic air supply without a blower, thereby being widely applied to the manufacture of warm air heaters.
Description
Technical field
The utility model relates to a kind of warm-air heating radiator, particularly a kind of electric heating device that is used on the warm-air heating radiator.
Background technology
At present, widely used warm-air heating radiator is generally the electrothermal room heater on the market, it mainly is to use Electrothermic wire by the form of radiation heating ambient air to be warmed, thereby reach the effect that changes indoor temperature, but the heating wire that uses in the existing warm-air heating radiator, the version that common employing is laterally arranged is arranged between air inlet and the air outlet, this version not only causes hot blast to form good heat exchange with air, but also to adopt the hot blast after pressure fan will be heated to take out of outside the machine, thereby cause indoor heating effect poor, and because the running of pressure fan, must bring the influence of noise, thereby be difficult to meet people's instructions for use.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of quickening cross-ventilation that is used on the warm-air heating radiator, has improved the electric heating device of rate of heat exchange.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of electric heating device that is used on the warm-air heating radiator, it comprises the substrate that vertically is arranged in more than between warm-air heating radiator air inlet and the air outlet, and the substrate longitudinal direction is provided with a plurality of jack holes, and cross-under has Electrothermic wire on each jack hole;
As a modification of the embodiment above, described substrate is two, is parallel to each other between the substrate; Be parallel to each other between described many Electrothermic wires;
As the further improvement to above-mentioned embodiment, described Electrothermic wire height is more than a times of Electrothermic wire width.
The beneficial effects of the utility model are: this electric heating device adopts Electrothermic wire and vertically is distributed between warm-air heating radiator air inlet and the air outlet, when room air when air inlet enters, room air is heated step by step by Electrothermic wire, room air absorbs heat from Electrothermic wire and becomes hot gas later on, generation is from lift, rely on the lift of self up to climb then along between the substrate or the air channel of housing formation, discharge from air outlet at last, thereby reach the effect that changes indoor temperature, and room air constantly replenishes from air inlet, thereby form free convection and become stack effect, this design realizes thermal natural convection and heat exchange when passing through electric heating device by room air fully, need not just can realize air-supply automatically by pressure fan, thereby can be widely used in the making of warm-air heating radiator.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1; a kind of electric heating device that is used on the warm-air heating radiator; it comprises the substrate 1 that vertically is arranged in more than between warm-air heating radiator air inlet and the air outlet; substrate 1 is arranged in the housing; form the air channel that air flows by housing; certainly can also be according to the actual needs the quantity of substrate 1 be designed to two or more than two; be parallel to each other between the described substrate 1; gap between the substrate 1 has formed the air channel that one or more air flow; described substrate 1 longitudinal direction is provided with a plurality of jack holes 11; cross-under has Electrothermic wire 2 on each jack hole 11; be parallel to each other between described many Electrothermic wires 2; certainly Electrothermic wire 2 also can adopt the form of electrothermal tube to replace; no matter but the structure of substrate 1 and Electrothermic wire 2; be provided with form how and quantity what; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
Operation principle of the present utility model is: this electric heating device adopts Electrothermic wire 2 and vertically is distributed between warm-air heating radiator air inlet and the air outlet, when room air when air inlet enters, room air is heated step by step by Electrothermic wire 2, room air absorbs heat from Electrothermic wire 2 and becomes hot gas later on, generation is from lift, rely on the lift of self up to climb then along between the substrate 1 or air channel of housing formation, discharge from air outlet at last, thereby reach the effect that changes indoor temperature, and room air constantly replenishes from air inlet, thereby form free convection and become stack effect, this design realizes thermal natural convection and heat exchange when passing through electric heating device by room air fully, need not just can realize air-supply automatically by pressure fan, thereby can be widely used in the making of warm-air heating radiator.
In order to obtain better stack effect, can highly be more than a times of Electrothermic wire 2 width with Electrothermic wire 2, the speed of free convection has effectively been accelerated in this design, improved rate of heat exchange, Electrothermic wire 2 height are bigger than more with Electrothermic wire 2 width, the free convection effect is good more, otherwise effect is poor more, solderless wrapped connection form as for Electrothermic wire 2, can be set to triangular form or trapezoidal etc., adopt the warm-air heating radiator of this electric heating device owing to have heat energy utilization rate height, noiselessness, simple in structure, the easy-to-install characteristics, thereby be fit to be used in office, the shop, places such as sentry box also are fit to general family and use as auxiliary heating.
