Abstract

The utility model discloses a directional heat-dispelling electrical heater, which comprises a shell body [1], a heating body [2] and a heat-conductive body [3]. The heat-conductive body [3] is arranged on the upper part inside the shell body [1], whose upper part directly contacts an upper cover [4] of the shell body; the a heat-preservation level [5] is arranged between other faces of the heat-conductive body [3] and the shell body [1]. The utility model uses a sealing mode of the heat preservation level to control the directional discharge of the heat; the technical proposal of the utility model is rational, which can decrease the heat losing greatly, enhance the heat efficiency and safety performance, decrease the use cost and prolong the life time. The utility model is suitable to be widely used in each application situation, which is a novel and applied energy-saving electrical heater.

Description

Directed heat release electric heater

The utility model relates to a kind of electric heater, particularly a kind of directed heat release electric heater with the unidirectional heat transfer of insulation material sealing control.

In the prior art, electric heater has been popularized in daily life and has been used, and as directly heating or the household electrical appliance assembly, mainly contains two kinds of bareing and sealed types usually.The heater of bareing electric heater exposes, directly contacts with air, and easily oxidation, aging and damage, it is bigger that heat distributes, and thermal efficiency ratio is lower, and security performance is poor; Though sealed type electric heater heater does not expose, fail safe is better, and its insulation and sealant all adopt thermal conductivity material preferably, its working face of Xu is absorbed outside the heat, its lap also distributes a large amount of heats simultaneously, causes serious thermal waste, thereby has reduced the efficient of heat energy utilization.

The purpose of this utility model is a kind of improved directed heat release electric heater that provides in order to overcome above-mentioned prior art shortcoming, and sealing control orientation is disengaged heat, reduces thermal loss, improves the heat efficiency, energy savings.

The purpose of this utility model can realize by following technical measures: this electric heater has heater, heat carrier, housing, heat carrier is that heat-conducting insulation material is made, heater is located in the heat carrier, heat carrier is located at the housing internal upper part, directly contact case top lid above the heat carrier, disengage face as heat, be provided with heat-insulation layer between other face of heat carrier and the housing, heat-insulation layer is made up of insulation material, promptly be to be full of insulation material between the side of heat carrier and following and the housing, play sealed, thermally insulated effect, control unidirectional heat release, the power supply wiring of heater from the side direction of housing or the end to drawing.During actual fabrication, heater is installed in and becomes as a whole in the heat carrier, lays insulation material in the housing, the pit identical with the heat carrier shape left on its top, and the heat carrier of packing into adds loam cake compacting sealing, contacts case top lid above the heat carrier, other face is sealed by heat-insulation layer, directed heat release.

Concrete structure of the present utility model and embodiment are provided by the following drawings.

Fig. 1 is a structure chart of the present utility model.

Below with reference to accompanying drawing the utility model is described in further detail: with reference to Fig. 1, this electric heater has housing [1], heater [2], heat carrier [3], heater [2] is laid in heat carrier [3] lining, as a whole, the sealing of housing [1] lower end, upper end open, housing [1] forms an inner chamber, heat carrier [3] is located at this inner chamber top, below heat carrier [3], be provided with heat-insulation layer [5] between side and the housing [1], heat-insulation layer [5] adopts filled thermal insulation materials to form, insulation material can be alumina silicate fibre, by case top lid [4] compacting sealing, case top lid [4] is the metal heat-conducting lid above the rock wools etc., heat carrier [3], disengage face as heat, the supply terminals of heater [6] end of to drawing.Housing [1], heat carrier [3], heat-insulation layer [5] upper surface are concordant, and with loam cake [4] sealing, housing [1] and loam cake [4] employing screw are connected and fixed.

The utility model is reasonable in design, and the mode of utilizing heat-insulation layer to seal is controlled the heat orientation and disengaged, and significantly reduces thermal loss, improve the heat efficiency and security performance, reduce use cost, length increases the service life, being fit to various application scenarios and promoting the use of, is a kind of energy-saving electric heater of Nover practical.

Claims

1, a kind of directed heat release electric heater, housing [1], heater [2], heat carrier [3] are arranged, it is characterized in that heat carrier [3] is located at housing [1] internal upper part, the top direct contact case top lid [4] of heat carrier [3] is provided with heat-insulation layer [5] between other face of heat carrier [3] and the housing [1].

2, electric heater according to claim 1, it is characterized in that heat carrier [3] the side and below heat-insulation layer [5] is arranged.
