Abstract

The utility model relates to an electric radiator, developed mainly for solving the problems that the existing electric radiator cools off quickly after power failure and stops heating indoors. The utility model mainly comprises a heating holding zone, a radiator, fins, an electric heater, heat conducting medium, etc., wherein, the out side of the casing of the holding zone is provided with a heat-insulating layer and an outer casing. The utility model has the advantages that major heat amount is reserved in the electric radiator after the power failure to maintain continuous indoor heating for a long period.

Description

A kind of electric heater

The utility model relates to a kind of electric heater.

Existing electric heater cools off after having a power failure very soon, stops to indoor heating.

The purpose of this utility model is can keep more after-heat after a kind of power failure of design, can keep the electric heater of a period of time continuation to indoor heating.

The purpose of this utility model is achieved in that it comprises heat tracing section 5, several radiators 1 are housed on the heat tracing section, fin 3 for heat transmission is arranged on the radiator, establish electric heater 4 in the heat tracing section, and dose heat-conducting medium, we establish heat-insulation layer 9 in heat tracing piece housing 8 outsides, and the heat-insulation layer outside is a shell 10.

Longer for the utility model is continued to the time of indoor heating after power failure, better effects if can be made radiator separately independent sealing, and fill heat-conducting medium in each radiator.

In addition, the radiator of existing electric heater all adopts oblate seam welding structure, and is not withstand voltage, and for withstand voltage, the radiator here adopts tubular structure, preferably seamless pipe.

The utility model has the advantages that after power failure can keep more heat in the electric heater, and keep one long period, continue to indoor heating; Particularly because radiator adopts tubular structure, withstand voltage, temperature can be up to 250 ℃ in the pipe, and do not ftracture.

Accompanying drawing 1 is that the utility model master looks the partial cutaway schematic diagram;

Accompanying drawing 2 is the utility model side-looking generalized sections.

Among the figure: 1. radiator; 2. indicator lamp; 3. fin; 4. electric heater; 5. heat tracing section; 6. switch; 7. power-line plug; 8. heat tracing piece housing; 9. heat-insulation layer; 10. shell.

Embodiment: at first make heat tracing section 5, at heat tracing piece housing 8 outsides dress heat-insulation layer 9, at heat-insulation layer outside casing 10, radiator 1 can be made of seamless boiler tube, and radiator is installed on the heat tracing section, establish electric heater 4 in the heat tracing section, and dose heat-conducting medium, fin 3 is established on radiator top, the sealing of radiator upper end, the lower end can be an opening, so that the heat-conducting medium in the heat tracing section enters; The radiator lower end also can seal, and as adopting sealing, then also will fill heat-conducting medium in radiator.

Claims (3)

1, a kind of electric heater, comprise heat tracing section [5], several radiators [1] are housed on the heat tracing section, fin [3] is arranged on the radiator, establish electric heater [4] in the heat tracing section and dose heat-conducting medium, it is characterized in that establishing heat-insulation layer [9] outside the heat tracing piece housing [8], the heat-insulation layer outside is shell [10].

2,, it is characterized in that radiator is independent separately the sealing, fills heat-conducting medium in each radiator according to the said electric heater of claim 1.

3,, it is characterized in that radiator adopts tubular structure, preferably seamless pipe according to claim 1 or 2 said electric heater.
