Abstract
The utility model discloses a heater which includes a magnetic core and an electric heating device. The magnetic core is a honeycomb structure which is provided with a plurality of through holes. The electric heating device is inserted into the plurality of through holes. Because a magnetic core assembly is used, the service life is improved and the electric and thermal conversion efficiency is improved. The magnetic core is a honeycomb structure which can be regarded as a casing. The plurality of through holes are arranged in the casing. The shapes of the through holes are not restricted. A comparatively large cavity is arranged in the casing. The shape of the casing is not restricted either. The electric heating device can be inserted into the through holes and reach different parts of the magnetic core so that the air can pass the electric heating device uniformly and fully and thus a problem of dry heating of blind zones of the prior heaters is prevented; and the heater is comparatively rapid in temperature rise and thus the heating efficiency is improved. The utility model also discloses an electric hot air blower including the heater.
Description
Technical field
The utility model relates to heating device technology area, relates in particular to a kind of electric calorifier and heater thereof.
Background technology
Electric calorifier is the first-selected product of modern industry thermal source upgrading, is the optimal heat wind regime configuration of the automated machines such as hot blast furnace conveyor, drying oven, baking oven, packaging machine.Electric calorifier is comprised of air blast, heater, control circuit three parts.
Wherein, heater is generally electrothermal tube or PTC assembly, PTC is the abbreviation of Positive Temperature Coefficient, the meaning is positive temperature coefficient, very large semi-conducting material or the components and parts of general reference positive temperature coefficient, have the problems such as intensification is slow, thermal inertia is large, hot blast rate is few, electric conversion efficiency is low, economic performance is poor, and the efficiency of heating surface is low.
Therefore, how providing a kind of heater, to improve the efficiency of heating surface, is current those skilled in the art technical problems urgently to be resolved hurrily.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of heater, to improve the efficiency of heating surface.Another object of the present utility model is to provide a kind of electric calorifier that comprises above-mentioned heater.
In order to achieve the above object, the utility model provides following technical scheme:
A heater, comprises magnetic core and electric calorifie installation, and described magnetic core is honeycomb structure, has a plurality of through holes on it, and described electric calorifie installation interts in described a plurality of through holes.
Preferably, above-mentioned electric calorifie installation is heating wire.
Preferably, above-mentioned electric calorifie installation shape twist.
Preferably, above-mentioned electric calorifie installation coil is inserted in described a plurality of through hole.
Preferably, above-mentioned electric calorifie installation is many.
The utility model also provides a kind of electric calorifier, comprises heater, and described heater is the heater as described in above-mentioned any one.
The heater that the utility model provides, comprises magnetic core and electric calorifie installation, and described magnetic core is honeycomb structure, has a plurality of through holes on it, and described electric calorifie installation interts in described a plurality of through holes.Owing to having used core assembly, improved useful life, and improved electric conversion efficiency, magnetic core is honeycomb structure, honeycomb structure can be thought a housing, on housing, be provided with a plurality of through holes, the shape of through hole is unrestricted, enclosure interior has a larger cavity, the shape of housing is also unrestricted, electric calorifie installation can intert in each through hole, arrive each position of magnetic core, air can be evenly and is passed through fully electric calorifie installation, can avoid the problem of existing heater blind area dry combustion method, and it is very fast to heat up, thereby improved the efficiency of heating surface.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of the heater that Fig. 1 provides for the utility model embodiment.
In upper Fig. 1:
Magnetic core 1, electric calorifie installation 2.
Embodiment
The utility model embodiment provides a kind of heater, to improve the efficiency of heating surface.
For making object, technical scheme and the advantage of the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1, the structural representation of the heater that Fig. 1 provides for the utility model embodiment.
The heater that the utility model embodiment provides, comprises magnetic core 1 and electric calorifie installation 2, and magnetic core 1 is honeycomb structure, has a plurality of through holes on it, and electric calorifie installation 2 interts in a plurality of through holes.Owing to having used magnetic core 1 assembly, improved useful life, and improved electric conversion efficiency, magnetic core 1 is honeycomb structure, honeycomb structure can be thought a housing, on housing, be provided with a plurality of through holes, the shape of through hole is unrestricted, enclosure interior has a larger cavity, the shape of housing is also unrestricted, electric calorifie installation 1 can intert in each through hole, arrive each position of magnetic core 1, air can be evenly and is passed through fully electric calorifie installation 2, can avoid the problem of existing heater blind area dry combustion method, and it is very fast to heat up, thereby improved the efficiency of heating surface.
And magnetic core 1 is honeycomb structure, and windage is less, and ventilation quantity is larger, can meet the intensification demand of larger space.
Wherein, electric calorifie installation 2 is heating wire, the bending that heating wire can be more random, and make directly to carry out heat exchange with cold air, generation hot blast, has further improved the efficiency of heating surface, and electrothermal tube of the prior art is by the process of spacer medium transferring heat.Electric calorifie installation 2 is shape twist, to improve the contact area with the air of magnetic core inside, improves the efficiency of heating surface, and can be that coil is inserted in a plurality of through holes, further improves the contact area with the air of magnetic core 1 inside, improves the efficiency of heating surface.Certainly, heating wire can be many, better effects if.
The utility model embodiment also provides a kind of electric calorifier, comprises heater, and heater is the heater as described in above-mentioned any one embodiment, thereby improves hot blast rate, the raising efficiency of heating surface of electric calorifier.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
