Description

A hot-air blower for radiator}

The present invention relates to a fan unit for a radiator, and more particularly, to a fan unit for a radiator, wherein both end portions of a plurality of radiating fins are flatly bent at predetermined intervals so as to prevent air from being transferred to both sides thereof, The heat is transferred to the plurality of heat radiating fins and heated air is supplied while the air is transferred to the upper and lower sides of the heat radiating fin by the warm air fan provided on either one of the upper and lower sides of the heat radiating fins, The present invention relates to a hot air fan for a radiator, which is capable of supplying hot air in a short period of time, and can be manufactured in a compact size by a reduced width, thereby being efficient in use as a hot air fan in a toilet or a small room.

Generally, a heat exchanger is a refrigeration cycle apparatus comprising a compressor, a condenser, an expansion valve, and an evaporator. The refrigerant cycle includes a condenser and an evaporator. The refrigerant exchanges the ambient temperature and heat and converts the refrigerant as a heat transfer medium from a liquid phase to a gas phase or from a gas phase to a liquid phase And the absorption heat or the heat of discharge generated in the process is used for cooling or heating, or for cooling or heating.

Here, the heat exchanger can be classified according to its shape. Among the most widely known heat exchangers, there is a so-called 'pin' type in which a plurality of cooling fins are inserted into a refrigerant pipe. The refrigerant circulates through the refrigerant pipe and performs heat exchange with the outside through a wall surface of the refrigerant pipe. A plurality of thin cooling fins are tightly coupled to the outer circumferential surface of the refrigerant pipe, The contact area is enlarged to maximize heat exchange efficiency.

As shown in Fig. 1, the fin-type heat exchanger has a thin plate-like heat exchange plate 3, and a plurality of the heat exchange plates 3 are coupled in parallel. The heat exchange plates 3 thus joined in parallel pass through the heat exchange plate 3 and are U-bent at both ends to form the main body 1 together with the pipes 2 connected thereto.

Here, thin plate-shaped heat exchange plates 3 among the elements forming the main body 1 are bonded to the surface of the pipe 2 so as to easily transmit heat, thereby widening the contact surface area with air.

When the refrigerant flows into the pipe 2, the fin-type heat exchanger having the above-described structure is disposed between the heat exchange plate 3 and the heat exchange plate 3 surrounding the outer surface of the pipe 2, or between the slit 5 formed in the heat exchange plate 3, The heat exchange with the refrigerant in the pipe 2 is performed.

However, the fin-type heat exchanger is difficult to be manufactured by miniaturization, and even if the fin-type heat exchanger is manufactured with a small size, heat exchange efficiency is low.
