Description

Heater blower {HEATING BLOWER}

The present invention relates to a heat-generating blower, and more specifically, to an exothermic blower in which the heat transfer efficiency is remarkably increased and the overall configuration is compactly constructed by simultaneously exerting the heat generating function and the blowing function.

Conventional heaters, such as heaters, are usually configured with heating coils inside and wirings for supplying electrical energy thereto.

The heating coil is fixedly arranged at a specific location inside the heating device, and heat generated from the heating coil by the supplied electric energy is transferred to the surrounding air by natural convection.

The heat transfer efficiency to the surrounding air is low only by installing the heating coil, and a device such as a blower fan for circulating air is usually installed around the heating coil, so that heat generated in the heating coil is smoothly transferred to the surrounding air. It is configured as possible.

However, even though the heat generated from the heating coil is transmitted to the ambient air through the blower fan, the heat transfer between the heating coil and the surrounding air is generated only in the area immediately around the heating coil, and the heat from the heating coil is generated through the blowing fan. It merely serves to move the delivered air to a specific location.

That is, from the viewpoint of intentional heat transfer, except for unintentional waste heat generated from the motor of the blower fan, the heat transfer is made only of the air immediately surrounding the heat generating coil, and the blower fan serves to transfer the transferred heat as above. It's nothing more than doing things.

This is inefficient in terms of the efficiency of heat transfer, and in order to increase the heat transfer efficiency between the heating coil and its surrounding air, the heat transfer efficiency is proportional to the size of the contact area, if the surface area of the heating coil itself is the same, the heating coil and It is desirable that the contact between the surrounding air is made more during the same time.

In this regard, rather than simply transferring the heat generated from the heating coil to a specific area through a blower fan, the heating coil moves in the air to contact the surrounding air more per unit time to transfer heat, and in this state The method of transferring to a specific area through the blower fan may increase heat transfer efficiency.

However, since the heating coil generates heat by supply of electrical energy, a terminal for electrical connection is coupled to the heating coil, and wirings for power supply must be connected.

Due to the limitations in the configuration of the heating coil as described above, the heating coil is fixedly installed at a specific location, and only a method of transferring heat generated from the heating coil to a specific area through a blowing fan is devised.

And, in order to transfer the heat transferred from the heating coil to the ambient air as described above, a blower fan other than the heating coil must be installed around the heating coil, and this point increases the volume of the entire device for heat transfer. There is a drawback to this complexity.

In addition, there is a disadvantage that unnecessary waste of electricity flowing through the heating coil, the blowing fan, and various components is generated.

The present invention has been devised to solve the problems as described above, and the object of the present invention is to simultaneously excite the heating function and the blowing function, thereby increasing the contact frequency per unit time between the heating unit and the ambient air, thereby significantly increasing the heat transfer efficiency.
