Description

PTC electroceramics heating inner bag

Technical field

The utility model relates to a kind of and supporting use of instant electric water heater or independent the use, and adopts the water heater heating inner bag field of PTC electroceramics heating material as heating.

Background technology

At present, the instant electric water heater that the domestic and international market is used, its heating heating major part that inner bag adopted is heating wire, nickel reeling, glass tube coating Electric radiant Heating Film type, it is heating that a small amount of part adopts the PTC electroceramics, its structural design often between the porous aluminum flat tube of PTC heating core body and water flowing the coated with thermally conductive adhesive curing be one.This heat transfer structure deficiency is: along with reality use in the increase of open and close power supply number of times, the heat-conducting glue coat tends to fade to rigidly from soft, causes heat-conducting effect variation gradually, will produce the problem of power attenuation.Under constant water flow, the temperature value of water outlet saliva can descend to some extent, and electric energy consumption does not but reduce, and in addition, the immediately heating water heater ubiquity of heating wire, nickel reeling heating element heater is short service life, shortcomings such as frequency of maintenance height, easy scaling.

The utility model content

The technical problems to be solved in the utility model provides a kind of PTC electroceramics heating inner bag, not only make water, electricity separate in the course of the work, and PTC ceramic heat core body is arranged in the bar shaped aluminum metal inner bag circulating water channel, can also improve the thermal efficiency effectively, reach the purpose of economize on electricity, energy-conservation, anti-power attenuation.

For addressing the above problem, the technical solution of the utility model is:

A kind of PTC electroceramics heating inner bag, include bar shaped inner bag housing, it is characterized in that: be provided with a plurality of in the described bar shaped inner bag housing along its inner bar shaped aluminum pipe of vertically arranging, the rear and front end of described bar shaped inner bag housing has been bolted to connection upper and lower envelope seat respectively, upper and lower envelope seat is sealed at both ends with bar shaped inner bag housing, between the bar shaped aluminum pipe certain interval is arranged, form water stream channel; Be provided with ceramic PTC heating core body in the described bar shaped aluminum pipe; Described ceramic PTC heating chip inside includes the PTC euthermic chip, the upper and lower end face of described PTC euthermic chip respectively is equipped with metal electrode film, described metal electrode film end is connected with plain conductor respectively and draws outside the described core body, described metal electrode film is coated with heat conducting insulating film, and described plain conductor is drawn from upper sealing base; On the described lower seal seat water inlet tap and faucet are arranged; Described water inlet tap and faucet respectively with water stream channel UNICOM.

Described a kind of PTC electroceramics heating inner bag, it is characterized in that: described bar shaped inner bag housing is an aluminum material, described upper and lower envelope seat is equipped with upper and lower capping outward.

Described a kind of PTC electroceramics heating inner bag, it is characterized in that: described heating core body includes 8 to 9 ceramic PTC euthermic chips parallel with one another, is provided with 6-8 bar shaped aluminum pipe in each bar shaped inner bag housing.

Described insulation film is coated with the bar shaped outer tube of heat conduction.

The beneficial effects of the utility model:

(1), electrical heating is to carry out in the metal inner tube circulating water channel of sealing, thereby prevents that effectively caloric value from by air ambient and other material dissipation, having guaranteed that electric energy changes the realization of heat energy equivalence value;

(2), adopt the calendering technology technology also further to improve the electroceramics chip is born in the heating core body in the inner container of electric water heater mechanical strength, shock strength and security reliability, the service life and the quality stability of product all increase significantly;

(3), compare, under the identical condition of discharge, electrical power, the utility model goes out water temperature value to be had significantly and exceeds with the heating inner bag of other structure type.
