Abstract
The utility model relates to a heating apparatus, wherein, the heat transfer system of the device adopts concave structure. The whole heating apparatus can be adsorbed on the surface of a heated body by a permanent magnet when required. Space is not occupied. A heating body adopts posistor with automatic temperature control. Thus, the heating apparatus has higher heat utilization rate. The utility model can be used for insulating and heating for various iron containers with curved surfaces.
Description
Model utility relates to a kind of heating equipment, particularly a kind of heating equipment with spill heating surface.
The heater of the insulation of existing iron ware, heating, heating surface all adopts plane structure, heater be heated, the transmission of heat by contact of cool-bag, mainly be at heater surfaces by the weight malleation that is heated container self.This heater has the iron ware of arc heating surface for some, owing to can not form comprehensive engagement, identical between heater heats face and heated object, thereby heats is undesirable, and heat loss is big; Secondly enough heavily can damage heater by pressure as heated object, in addition, when the need heating surface is being heated the sidepiece of container, both transmission of heat by contacts need add colligation in addition and compress, and are very inconvenient.
The purpose of model utility is to overcome the prior art deficiency, provide a kind of simple in structure, highly versatile can be used for the heating of arc shaped surface iron ware, and can keep the New Heating that closely contacts direct conduction heat sources automatically of heating unit and heated object (face).
Model utility is made up of thermal conductor and the electrical heating elements that is positioned at thermal conductor one side, it is characterized in that described thermal conductor is the concaver with concave structure, at the concaver dorsal part absorption permanent magnet is arranged.The model utility electrical heating elements can be low-power as=＜resistance heater or the conductive film of 100W, wherein a kind of scheme preferably is for adopting the PTC positive temperature coefficient thermistor, to realize the temperature automatically controlled of electrical heating elements, omit temp-controlling element, electrical heating elements PTC by onesize with it pellet electrode and arc-shaped electrode be electrically connected outward, each electrical heating elements PTC in company with electrode slices have one independently insulation crust encapsulate.The concave surface thermal conductor can adopt the monolithic plate-like to or have the box like structure of a concave surface at least, its dorsal part is distributed with and is used to make heating equipment to be adsorbed on the permanent magnet on heated object surface automatically, both reduced and be used to support or the fixing annex of heating equipment, can make heating equipment closely connected again in the heated object surface, form good transmission of heat, also convenient simultaneously the installation changed, and do not account for volume location.Above-mentioned electrical heating elements closely is affixed on concave surface thermal conductor dorsal part, and the heat major part that heater is produced heats thermal conductor with transmission of heat, and by thermal conductor conduction heating heated object, to improve the heat energy utilization rate to greatest extent.For reducing heat loss, heating equipment and heated object non-contact face are provided with thermal insulator.
Below by embodiment, with reference to the optimised form of description of drawings model utility:
Fig. 1 is the 1st embodiment's a structural representation.
Fig. 2 is the 2nd embodiment's a structural representation.
Fig. 3 is electric heating part element and electrode slices schematic representation.
The 1st embodiment: the concaver 1 and the pallet 2 that same structure are arranged with the punching out of good conductor sheetmetal and the heated object heating surface of heat.Electrical heating elements PTC10 is clamped by the electrode slices 11 and the arc-shaped electrode sheet 12 of homalographic with it, and is insulated 13 encapsulation of heat transfer shell.PTC electrical heating elements 3a, the 3b of insulation-encapsulated and permanent magnet 4 are connected and fixed part 5 by pallet 2 and are pressed on the concaver dorsal part.The non-heating surface of heater is by lagging casing 6 parcels of expanded polystyrene compacting.
The 2nd embodiment: suppress concave surface loam cake 7 and lower cover 8 respectively with sheetmetal, PTC electrical heating elements 3a, 3b and the permanent magnet 4 of insulation-encapsulated pressed in concave surface upper cover plate dorsal part through pallet 2 fixed blocks 5, in the box with 9 fillings of expanded perlite insulating material.
The model utility thermal conductor is owing to adopt and heated object heating surface isomorphous structure, and by permanent magnet absorption connection, can easily heater be attached at the heated object surface during use, simple in structure, the space does not occupy, have very high heat utilization efficiency, the PTC electrical heating elements has guaranteed that heater heats heated object with a steady temperature.The model utility heater can be used for various iron wares, particularly has the iron ware heating of arc heating surface.
