Description

A kind of liquid heating of tape thickness film circuit heating board

Technical field

The utility model relates to family expenses and industrial electric apparatus technical field, relates to a kind of liquid heating in particular.

Background technology

Existing liquid heating is that electrothermal tube and water channel is placed side by side mostly, its structure is in the outside of water channel heating to be installed, using maximum is electrothermal tube heating piece, by heating metal tube is heated, and electrothermal tube heating piece surface thermal load is 10W～15W/cm ², and thermal inertia is big, starts slowly, and electrothermal tube surface thermal load under water can not surpass 30W/cm yet ², the thermal efficiency only has 57%, makes electric power big, poor stability, and power savings is poor.

Summary of the invention

The purpose of this utility model is exactly that provide for the deficiency that solves prior art a kind of not only is easy to design and manufacturing, range of application is very extensive, and the liquid heating of the tape thickness film circuit heating board of energy-conserving and environment-protective.

The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of liquid heating of tape thickness film circuit heating board, the temperature control equipment, the power supply base that comprise kettle body, heater, seal and the control heater of loading liquid, it is characterized in that: described heater mainly is made of the heating plate of tape thickness film circuit, this heating plate is whole plank frame, combines with the kettle body.

As further specifying of such scheme, described heating plate is provided with controlled thick film circuit heating track, and double temperature control switch, dielectric, water channel and electrode ejector also are installed on this heating plate.

Described temperature control equipment is installed in the housing of this device, and its outside input circuit is serially connected with power switch, cup bit switch successively.

Described controlled thick film circuit heating track is meant by the rare earth thick film circuit preparation on metal substrate or devitrified glass or micro-crystalline ceramic substrate the heater that its Curie-point temperature is controlled; The control circuit that the temperature-sensitive control circuit is made up of on substrate responsive electric slurry of PTC positive temperature coefficient and rare earth thick-film resistor paste (thermistor slurry) preparation.

Described temperature control equipment is installed in the working face of heating plate, and this device is used for carrying out overtemperature protection and overcurrent protection for temperature controller or Electronic Control plate.

Also be provided with the Zhou Bianhuan that makes by heat proof material that is used to support heating plate in the described kettle body.

The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:

1, energy-conservation, utilize the heat conductivity of thick film circuit substrate, make liquid directly and substrate contacts, in contrast to the insulating pot of traditional type, thermal efficiency height not only starts fast and compares energy-conservation 15%～30% with traditional electrical heat pipe heat-generating disc.

2, controlled water temperature can provide 85 ℃～98 ℃ water according to different needs.

3, thermal efficiency height makes full use of the advantage of the controlled heating of thick film circuit, and curie point is controlled, the control mode novelty, and the circuit trace of thick film heating can arbitrarily design, and does not have the heating blind area, can design and make homogeneous temperature field.
