Description

A kind of dedicated PTC water heater of floor heating

Technical field

The utility model belongs to electronic component manufacturing technology field, and in particular to a kind of dedicated PTC water heater of floor heating.

Background technique

Currently, mainly heating using central heating or small coal in the heating of north of China family, it is a large amount of to require burning Coal is as heating source.The heating system will cause serious atmosphere pollution and efficiency of heating- utilization is low, increasingly stringent in country Environmental requirement under be difficult to exist down.Current country is just wideling popularize coal and is changing electrical engineering, to ban large quantities of coal heating items Mesh, so electric heating floor heating has welcome development opportunity.Current electric heating floor heating mainly uses recirculated water as heating medium, has The advantages that degree of safety is high, and efficiency of heating- utilization is high.But the common boiler using electric-heating-wire-heating often occurs, and the service life is short, decaying is fast, The bad phenomenons such as dry combustion method breakdown.

Summary of the invention

The technical problem to be solved by the utility model is to provide a kind of dedicated PTC water heaters of floor heating, for ground chafing dish The water of furnace heats, have the characteristics that service life length, attenuation rate bottom, can with dry combustion method, be easily installed.

The utility model technical scheme applied to solve the technical problem is: a kind of dedicated PTC water heater of floor heating, including PTC heat generating core, power supply line and tubulose aluminum alloy casing, the PTC heat generating core include PTC fever tablet, electrode slice and insulating film, institute PTC fever tablet two sides heat conductive silica gel bonding electrode slice is stated, the electrode slice is sheet rectangle and is equipped with wire interconnecting piece, Insulating film is wrapped up in the connecting wire on the wire interconnecting piece of the electrode slice, the electrode slice outside；Outside the tubulose aluminium alloy Shell includes outer cover body, and the outer cover body is externally provided with the hollow cuboid of four or more even number arrangement, the PTC hair Hot core is set in hollow cuboid, is placed pressing die stick when compression in tubulose aluminum alloy casing, is set in the outer cover body There are several cooling fins, tubulose aluminum alloy casing both ends are intake-outlet.

As a further improvement, the tubulose aluminum alloy casing outer layer is equipped with foamed silica gel thermal insulation layer.

The beneficial effects of the utility model are: design is scientific and reasonable, good appearance is easy to use, automatic constant-temperature-heating, Open fire is not generated, watt level is adjustable, the popularization and use of floor heating homogeneous solution-type reactor suitable for home use, has service life long (7 years or more), decaying Rate bottom, can with dry combustion method, be easily installed the characteristics of.

Specific embodiment

In conjunction with shown in each attached drawing, a kind of dedicated PTC water heater of floor heating, including PTC heat generating core 1, power supply line and tubular aluminum Alloy shell, the PTC heat generating core include PTC fever tablet 4, electrode slice 5 and insulating film 6, and 4 two sides of PTC fever tablet are used Heat conductive silica gel bonds electrode slice 5, and electrode slice 5 is sheet rectangle and is equipped with wire interconnecting piece 7, in the conducting wire of the electrode slice 5 Connecting wire on interconnecting piece 7 wraps up insulating film 6 outside the electrode slice 5；The tubulose aluminum alloy casing includes outer cover body, The outer cover body is externally provided with the hollow cuboid 2 of four or more even number arrangement, during the PTC heat generating core 1 is set to It in empty cuboid 2, is compressed using hydraulic press, places pressing die stick when compression in tubulose aluminum alloy casing, prevent pressing process There is metaboly in middle aluminum alloy body.Several cooling fins 3, tubulose aluminum alloy casing both ends are equipped in the outer cover body For intake-outlet.The tubulose aluminum alloy casing outer layer is equipped with foamed silica gel thermal insulation layer.2 side of hollow cuboid is equipped with Slot is deformed, slot compressive deformation is deformed when compacting, to fix PTC heat generating core 1, PTC heat generating core 1 is made to be close to outer cover body.

The assembling process of the utility model are as follows: multi-disc PTC heater element is arranged side by side, and two sides heat conductive silica gel bonds stainless Steel electrode slice, rivets conducting wire on the wire interconnecting piece of electrode slice, and outside package insulating film forms PTC heat generating core, will wrap up The PTC heat generating core of insulating film is filled in the hollow cuboid of outer cover body, is compressed using hydraulic press, is needed outside in compaction process Dedicated pressing die stick is filled in the limbers of shell ontology, prevents outer cover body in pressing process from metaboly occur.It is every when compacting It is secondary while suppressing two faces symmetrical above and below.

The specific embodiments described herein are merely examples of the spirit of the present invention.The utility model institute Belonging to those skilled in the art can make various modifications or additions to the described embodiments or using similar Mode substitute, but without departing from the spirit of the present application or beyond the scope of the appended claims.
