Abstract

The utility model relates to an electric heater, in particular to a liner wall heat exchange water box, which comprises a cylinder, an upper seal head and a lower seal head, wherein the upper seal head and the lower seal head are connected with two ends of the cylinder. A heat conducting aluminum plate is arranged on the circular surface of the cylinder, and the heat conducting aluminum plate is wrapped by a work medium coil tube. The liner wall heat exchange water box has the advantages of 1 solving the problems of small heat exchange area of the coil tube outside a liner and incapability of sufficiently absorbing medium energy, 2 improving heat exchange efficiency and effectively balancing medium temperature as the work medium coil tube and the heat conducting aluminum plate are formed into a whole, and 3 facilitating installation of the work medium coil tube as a U-shaped concave position is arranged on the heat conducting aluminum plate.

Description

A kind of liner wall heat exchange type water tank

Technical field

The utility model relates to electric heater, specifically is a kind of liner wall heat exchange type water tank.

Background technology

The used water tank of the Teat pump boiler of existing market, adopt the heat exchange mode of following three kinds of forms substantially:

1, inner disc tubular type heat-exchanging water tank: this water tank places the inner bag the inside with heat exchange coil, heat exchange coil directly contacts with water, this water tank has advantages such as cost is low, heat exchange efficiency is high, mixed regimen condition is low is arranged, but after having long-time running, heat exchange coil is because contact with water, be easy to generate phenomenons such as fouling, corrosion, cause heat exchange efficiency to descend even corrosion failure, heat exchange coil will be in case water inlet will cause the serious problems of heat pump main frame damage, in case heat transferring medium infiltrates water tank simultaneously, also can the water of water tank the inside be polluted, and the shortcoming that causes water tank to scrap.

2, water cyclic heating water tank: this water tank places heat pump main frame the inside with the heat exchange tubulature, adopt the water in plate type heat exchanger or double pipe heat exchanger and the circulation line to carry out heat exchange, then the high-temperature water in the circulation line flow to by water pump operation in the water tank with water tank in cold water carry out heat exchange, thereby come the water of heating water tank.This water tank has heat exchange efficiency height, heat exchanger components advantage such as can change, but it is higher also to exist heat exchange sleeve or plate type heat exchanger to contact the back temperature with water, scaling influences heat exchange efficiency easily, simultaneously because increased the power of water pump as water running, the shortcoming that cost is higher also has water tank to mix shortcomings such as the regimen condition is serious in addition.

3, outer coil pipe heat-exchanging water tank: this water tank as for the inner water tank outside, directly twines coil pipe with heat exchange coil on the inner bag stage casing, this water tank has heat exchange coil and do not contact with water, the structureless advantage of no burn into, but exist heat transfer coefficient low, heat exchange area is little; Under pressured state, the shortcoming of coil pipe easy deformation.

The utility model content

The purpose of this utility model is to overcome the shortcoming that said structure exists, and provides a kind of heat exchanger tube not contact with water, does not have the generation of fouling and etching problem at all, has improved heat exchange area, the on-deformable liner wall heat exchange type water tank of working medium coil pipe.

The utility model is realized with the following methods: comprise cylindrical shell, and the upper and lower end socket that connects the cylindrical shell two ends, the circular surfaces on its described cylindrical shell is provided with the heat conduction aluminium sheet, and the heat conduction aluminium sheet is enclosed with the working medium coil pipe.

Described working medium coil pipe and heat conduction aluminium sheet be shape in the shape of a spiral, and the cross section of heat conduction aluminium sheet is U shape recess, on the U shape recess opening is arranged, and the working medium coil pipe is embedded in the U shape recess place of heat conduction aluminium sheet, and opening communicates with working medium coil pipe one side disc.

Described low head is semicircle sphere-like indent in the cylinder lumen place, and the limit of low head and cylinder inboard wall face link into an integrated entity.

The beneficial effects of the utility model are: it is little 1, to have solved the outer coil pipe heat exchange area of courage, fully the problem of absorbing medium energy; 2, working medium coil pipe heat conduction aluminium sheet forms an integral body, has improved heat exchange efficiency, effectively the balance media temperature; 3, having U shape recess to help the working medium coil pipe on the heat conduction aluminium sheet installs.
