Abstract

The utility model relates to a multi-cavity heater of an electric water heater. The multi-cavity heater is characterized in that the multi-cavity heater also comprises a seal cover and a heat conductor; the casing also comprises a left cavity and a right cavity respectively provided with an upper opening; the seal cover is fixedly connected with the upper openings and sealed by liquid; an aqueduct is arranged between the left cavity and the right cavity; the upper end of the aqueduct is communicated with the left cavity, and the lower end is communicated with the left cavity; a water outlet pipe is arranged in the left cavity, the upper end of the water outlet pipe is communicated with the left cavity, and a sewage-discharge port is arranged at the bottom of the left cavity; a water inlet is arranged at the lower end of the right cavity, and communicated with the water outlet pipe; heating fins are coated in the heat conductor, a insulation heat conduction layer is arranged between the heating fins and the heat conductor, and a plurality of heat radiation fins are arranged on the heat conductor; and a joint part on the heat conductor is fixedly connected with the seal cover to achieve liquid seal. As the structure is adopted, the casing is formed once; compared with the prior art that the casing is folded multiple times, the heater has simple technology. The heat conductor is provided with the heat radiation fins, and the heat conductor and the heat radiation fins are in full contact with the water, which prevents water scaling by local high temperature.

Description

The multi-cavity type heater of electric heater

Technical field

The utility model relates to a kind of device of electric heater, especially a kind of heater of electric heater.

Background technology

Present prior art, Chinese patent ZL0324229.2, invention and created name: efficient stacked-up type electric heater, comprise the stacked stratiform housing that forms and be embedded in outer layer of stratiform housing and the electric heating layer between the layer, be provided with water chamber in the stratiform housing, water chamber is at least two eclipsed form cavitys that adapt with the stratiform housing that be communicated with at stem or afterbody.Existing problems are: complex process, and the distortion of bending part water chamber, water chamber is heated inhomogeneous, easily scaling.

Summary of the invention

The purpose of this utility model is: a kind of multi-cavity type heater of electric heater is provided, and not only technology is simple for it, and can prevent that hot-spot from producing incrustation scale.

The utility model is achieved in that a kind of multi-cavity type heater of electric heater, comprise housing, heating plate, water inlet adapter and water outlet adapter, its special character is: also comprise a capping, heat carrier, described housing comprises the left inner chamber with upper shed, right inner chamber, capping and upper shed are fixedly connected and liquid sealing, one water guide pipeline is arranged between the left and right inner chamber, water guide pipeline upper end communicates with right inner chamber, the lower end communicates with left inner chamber, a left side also has an outlet pipe in the chamber, the outlet pipe upper end communicates with left inner chamber, in the bottom of left inner chamber one sewage draining exit is arranged; Right inner chamber lower end has water inlet, outlet pipe to communicate with delivery port; Heating plate is coated in the heat carrier, and the insulating heat-conductive layer is arranged between heating plate and the heat carrier, and there is several cooling fins on the outer surface of heat carrier; The joint area of heat carrier upper end passes the installing hole of capping, and is fixedly connected with capping, reaches liquid sealing.

The multi-cavity type heater of described electric heater, its special character is: the outer surface of fin has the insulating heat-conductive oxide layer on described heat carrier and the heat carrier.

The multi-cavity type heater of the utility model electric heater owing to adopt such structure, the housing one-shot forming is made, with the prior art middle shell repeatedly bending compare, technology is simple; Several cooling fins is arranged on the heat carrier, and heat carrier, fin fully contact with water, have prevented localized hyperthermia and produce incrustation scale.
