Description

Heat exchanger using electric heater {HEAT EXCHANGER USING AN ELECTRIC HEATER}

The present invention relates to a heat exchanger, and more particularly, it is possible to directly heat the liquid fluid injected into the heat exchanger through the heat transfer heater to solve the limitation of space utilization due to the installation of a separate heating device and piping and In addition, the present invention relates to a heat exchanger using an electrothermal heater to obtain thermal efficiency improvement and energy saving effect due to heat loss prevention.

A heat exchanger is a device that sends heat energy of a high temperature fluid to a low temperature fluid.

It is common to use gas and liquid as the fluid, but in some cases, solid and fluid may be used together.

It is used in various devices such as heaters, coolers, evaporators, condensers and the like.

On the other hand, the majority of the existing heat exchanger was not only installed a separate heating device for heating the fluid inside the heat exchanger, but also generally installed a pipe connecting the heating device and the heat exchanger.

However, since the existing heat exchanger in which the separate heating device and the pipe are installed in this way has a considerable volume, the installation location was limited, the installation cost was considerable, and the installation time was long.

In addition, the existing heat exchanger that is equipped with a heating device and piping is because the fluid is circulated in the heat exchanger, piping, heating device can not only heat the fluid inside the heat exchanger, but also need to heat the fluid contained in the heating device and piping,

Not only did it take a long time to heat the fluid to the target temperature, it caused a significant energy consumption,

There was a problem in that heat loss occurred while the fluid was moved from the heating apparatus to the heat exchanger along the pipe and the thermal efficiency decreased.

The present invention was devised in view of the above situation,

By installing an electric heater on the heat exchanger itself without installing a separate heating device and pipe for heating the fluid injected into the heat exchanger, it is possible to directly heat the fluid injected into the heat exchanger through the heat transfer heater,

Eliminate the limitation of space utilization due to the installation of a separate heating device and piping,

It is an object of the present invention to provide a heat exchanger using an electrothermal heater that prevents unnecessary energy consumption and heat loss to achieve cost savings by saving energy and improving thermal efficiency.

Heat exchanger (A) using the heat transfer heater of the present invention for achieving the above object,

It is provided with an upper body 10 and the lower body 20 made of a plate shape of a predetermined thickness empty inside,

While connecting the plurality of heat dissipation tube 30 of a predetermined length between the upper body 10 and the lower body 20,

At the bottom of the lower body 20, a plurality of heat heaters 40 having a heating part 41 having a length close to the length of the lower body 20 are installed at regular intervals, but the heating part 41 of the heater 40 is provided. ) Is installed to be located inside the lower body 20,

One end of the upper body 10, characterized in that the one end is provided by the auxiliary tank 50 having a connecting pipe 51 leading to the inside of the upper body 10, in more detail based on the accompanying drawings The explanation is as follows.

As shown in FIG. 1 and FIG. 2, the present invention has a plurality of heat dissipation tubes 30 having a predetermined length between upper and lower bodies 10 and 20 having a rectangular plate shape, and a plurality of lower portions of lower body 20. Electrothermal heater 40 is installed,

The heat transfer heater 40 is a length of the heat generating portion 41 is close to the length of the lower body 20, the heat generating portion 41 of the heater 40 is installed in the lower body 20, the lower body ( 20) to directly heat the fluid 70 is filled inside,

In the present invention, a general flange heater with a temperature sensor was used.

And, the upper side of the upper body 10 of the present invention is provided with an auxiliary tank 50 made of a cylindrical,

The lower end of the auxiliary tank 50 is connected to the connection pipe 51, one end of the connection pipe 51 is connected into the upper body (10).

3 is a fluid 70 is filled in the upper body 10, the lower body 20, the heat dissipation tube 30, as shown in the cross-sectional view of the present invention,

The heating part 41 of the heater 40 is installed in the lower body 20, and the heating part 41 of the heater 40 is operated by power supply, thereby making the fluid 70 filled in the lower body 20. ) Can be directly heated,

The fluid 70 heated inside the lower body 20 is circulated through the heating tube 30 and the upper body 10 by the convection phenomenon so that the temperature of the entire fluid 70 rises evenly.

When the fluid 70 is heated by the above process to reach a certain temperature, the heater 40 stops its operation and then operates when the fluid 70 reaches a predetermined temperature or less, so that the fluid 70 can maintain a constant temperature range.
