Abstract

The utility model discloses an electric heater that heat transfer is even, it includes heat transfer pipeline (1), cavity (2), heating device (3) and one or more heat exchange piece (4) to and the controller, the both sides of cavity (2) are located with heat transfer pipeline (1) branch to heat exchange piece (4), and heating device (3) are filled in cavity (2), and heating device (3) are connected with the controller electricity. The utility model provides an electric heater that heat transfer is even adopts thermal element to replace traditional heating wire, electrothermal tube, has not only reduced manufacturing cost, has prolonged life moreover, and the temperature is controllable, adopts heat transfer pipeline, ensures to wait to heat the temperature average in the space, and heat transfer efficiency is faster.

Description

Uniform electric heater conducts heat

Technical field

The utility model relates to heater, the uniform electric heater of particularly a kind of heat transfer.

Background technology

The firing equipment that is used for commercial production at present adopts heating wire or electrothermal tube as the main heating element mostly, under the bigger situation in space to be heated, can't guarantee that heating is average in the space to be heated; It is too high some position temperature very easily to occur, and unfavorable condition such as some position temperature is not enough, its temperature is uncontrollable; When breaking down; Its surface temperature sharply raises, and situation such as rubescent appear in heater element, have reduced useful life.

The utility model content

The purpose of the utility model promptly is to overcome the deficiency of prior art, provides a kind of heat transfer uniform electric heater, and it is uncontrollable to have solved present electric heater temperature, can't guarantee problem such as temperature-averaging in the space to be heated.

The purpose of the utility model realizes through following technical scheme: uniform electric heater conducts heat; It comprises heat transfer pipe, cavity, heater and one or more heat exchanging fin; And controller; Heat exchanging fin and heat transfer pipe are divided into the both sides of cavity, and heater is filled in the cavity, and heater is electrically connected with controller.

Described heater is a temperature-sensitive element.

The beneficial effect of the utility model is: the utility model provides a kind of heat transfer uniform electric heater; Adopt temperature-sensitive element to replace traditional heating wire, electrothermal tube, not only reduced production cost, and prolonged useful life; Controllable Temperature; Adopt heat transfer pipe, guarantee temperature-averaging in the space to be heated, heat transfer efficiency is faster.

Description of drawings

Fig. 1 is the structure chart of the utility model;

Among the figure, 1-heat transfer pipe, 2-cavity, 3-heater, 4-heat exchanging fin.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further description, but the protection range of the utility model is not limited to the following stated.

As shown in Figure 1; The uniform electric heater that conducts heat, it comprises heat transfer pipe 1, cavity 2, heater 3 and one or more heat exchanging fin 4, and controller; Heat exchanging fin 4 and heat transfer pipe 1 are divided into the both sides of cavity 2; Heater 3 is filled in the cavity 2, and heater 3 is electrically connected with controller, and described heater 3 is a temperature-sensitive element.

Claims

1. uniform electric heater conducts heat; It is characterized in that: it comprises heat transfer pipe (1), cavity (2), heater (3) and one or more heat exchanging fin (4); And controller; Heat exchanging fin (4) and heat transfer pipe (1) are divided into the both sides of cavity (2), and heater (3) is filled in the cavity (2), and heater (3) is electrically connected with controller.
