Abstract

The utility model relates to a liquid electrical heater with radiating fins, which is a liquid electrical heater. Because the heating tube of liquid electrical heaters which adopt prior art is a light wall tube, the liquid electrical heaters which adopt prior art have low heating efficiency and short life time. The utility model is characterized in that a heating tube is added with heat sink; the heat sink is fixed with the heating tube. Thus, the utility model is suitable for water heaters, automatic electrical water boilers, automatic electrical rice steaming implements, cosmetic steaming implements, liquid electrical heating occasions, etc. The utility model has the advantages of high heating efficiency, better energy saving effect, long service life, large water output, etc.

Description

Liquid electrical heater with radiating fin

The utility model relates to a kind of electric liquid-heating appliance, particularly a kind of electric heater unit that has fin, and it is applicable to the occasion of any need with liquid heat.

Liquid electric heater of the prior art, all form (as shown in Figure 1) by light wall shape heating tube, resistance wire and the connector lug that has a securing member, although its shape has hundreds of, can be flange plate type, Luo Xuan tubular type, v-shaped tube formula, W type tubular type, Z type tubular type or the like, but its structure all is identical, heating tube all adopts smooth wall pipe, so all there is following shortcoming in actual use: 1, the heat efficiency is low, and the heat efficiency is greatly about about 65%; 2, useful life short, and can scrap immediately during heating tube generation dry combustion method.

The purpose of this utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of heat efficiency height, the long liquid heater that has fin of life-span are provided.

The purpose that the utility model proposed can be achieved through the following technical solutions: also be provided with fin on heating tube, this fin and heating tube are fixed.

Description of drawings is as follows;

Fig. 1 is the structural representation of U type tubular heater in the prior art.

Fig. 2 is a structural representation of the present utility model.

Fig. 3 is an A of the present utility model place amplification view.

Fig. 4 is used in structural representation in the electric heater for the utility model.

Following the utility model will be in conjunction with the accompanying drawings, and further describe by embodiment.

Referring to Fig. 2, Fig. 3, this heater mainly is made up of heating tube 1, fin 2, seal 3, securing member 4 and connector lug 5, resistance wire 6, fin 2 is fixed on the heating tube 1, the shape of this fin 2 can be a helical form, resistance wire 6 is installed in the heating tube 1, seal 3 for making resistance wire 6 and heating tube wall 1 ' high-temperature insulation, is added with crystal magnesium oxide 7 in heating tube 1 between heating tube 1 and securing member 4; Securing member 4 can be divided into all kinds of ring flange tubular type securing members and the box securing member of all kinds of thread seal circles or the like.

During use, put into water,, can obtain hot water after the several seconds then with connector lug 5 and power connection as long as will have the heating tube 1 of fin 2.At this, even the accidental situation that dry combustion method several times occurs, because fin 2 is arranged, heating tube 1 is still excellent.

In addition, the utility model is equally applicable to the electric heater of profile for other shape, as v-shaped tube, helix tube, W type pipe, B-mode pipe electric heater or the like.Equally, the utility model also is applicable to electric shower-bath, automatic electric water-boiling device, automatic electric rice cooker, cosmetic steamer or the like.

Referring to Fig. 4, this Figure illustrates the operating position of the utility model in electric heater.This electric heater mainly by inlet opening 7, cylindrical shell 9, have fin 2 heating tube 1, form by the end of a thread 5, indicator light 11 and apopore 16, the heating tube 1 that has fin 2 is installed in cylindrical shell 9 interior indicator lights 11 and extinguishes when thermostat 17 high temperature cut off the power supply automatically, connects simultaneously when temperature is recovered normally to send electricity automatically; 10 is loam cake; 12 is the flange securing member, and it and heating tube 1 welding are fixed; 13 is seal; 14 is flange, and it and cylindrical shell 8 welding are fixed; 17 is the washing head support, is used for fixing the position of apopore 15.18 are hook, in order to hang this water heater.

During use, the heating time of this electric heater is 8 seconds only, and water yield is the electric heater increase about 30% of smooth wall pipe than heating tube.

The utility model compared with prior art has the following advantages: 1, reasonable in design, area of dissipation enlarge five-octuple, and the thermal efficiency brings up to 98% by original 65% About; 2, owing to rapid heat dissipation, greatly prolong its service life, even dry-fire condition occurs accidentally, heating tube can not damage yet; 3, water yield is big, and its water yield increases about 30% than existing product, and applicability is wide, has fabulous energy-saving effect.

Claims

1, a kind of liquid electric heater that has fin, comprise heating tube, resistance wire, seal, securing member and connector lug, resistance wire is installed in the heating tube, seal is between heating tube and securing member, it is characterized in that: also be provided with fin 2 on heating tube 1, this fin 2 is fixing with heating tube 1.

2, electric heater as claimed in claim 1 is characterized in that: the shape of fin 2 can be a helical form.
