The present invention relates to a cold and hot air fan, and more particularly to a cold and hot air fan used for controlling the temperature of a factory or a livestock farm.

For example, a conventional cold air blower is a method of directly wetting cold water with a cooling filter or wet ice melted water, and then absorbing the latent heat required for evaporation of the cooling filter to blow air at a lower temperature. The cooling water was circulated directly in the copper pipe and sensible heat exchange with air was used. Therefore, it is difficult to use in places where a large amount of cold air is required, such as a large factory or a livestock farm, because it requires frequent replacement of the cooling filter, a small amount of blown air, a heavy weight, and a low cooling efficiency compared to the production cost. .

In addition, in the case of a hot air fan, it is difficult to combine with a cold air fan, and thus a heater must be separately provided, and an air conditioner that combines air conditioning and heating has a problem of high price and installation cost.

In the housing of the cold / hot air blower of the present invention, it is preferable that the cross section of the blower is smaller than the intake portion in order to increase the flow rate of the air flowing therein and to send the cold / hot air to the large indoor space.

The heat exchange member used in the cold / hot air blower of the present invention is preferably made of an aluminum material having low cost and excellent moldability, corrosion resistance and thermal conductivity.

The multi-tube can have a cross section such as a rectangle or an ellipse.

 The header can have various cross sections, such as a rectangle, a circle, an ellipse, and does not need to be a microtubule such as a multi-tube.

In addition, the heat exchange member may be circular, elliptical, but it is easy to manufacture a rectangular because the plurality of plate-shaped multi-tubes are connected to the header by brazing.

On the other hand, the heat exchange member is coupled to the intake portion of the housing, it is preferable to install the heat exchange member in a fixed or removable manner, to enable the opening and closing using a hinge or the like.
