Also, by adopting the drum type heat transfer means, the operation cycle of the heat exchanger can be shortened and sufficient heat transfer area can be secured. It relates to a drum type heat exchanger that can improve the overall performance.

In general, the means for ventilating the interior of a factory or building or house is mainly to vent or direct air, such as a fan.

The ventilation means as described above are inefficient in terms of thermal efficiency by releasing energy by discharging cold or hot air to the outside in the summer or winter.

Recently, many heat exchangers have been provided to supplement these shortcomings.

These heat exchangers extract heat and moisture from the inflow of air and transfer it to the exhaust stream, thereby maintaining proper ventilation and maintaining air conditioning. The opposite flows of the exhaust air and the inlet air are required to pass through the heat exchanger. Means for applying pressure include fans or blowers.

In an electrothermal heat exchanger, the application technology of the heat transfer means for enhancing the heat transfer efficiency between the opposing air flows is most important, and many studies and improvements have been made.

For example, a heat exchanger provided with a representative disk-type heat transfer means among existing heat exchangers has been proposed (Utility Model Registration No. 274948, filed by the applicant of 2002.02.07), but such a heat exchanger has a sufficient heat transfer area. In order to ensure the size of the disk to be secured, the overall area and volume of the heat exchanger was increased, thereby causing inconvenience in handling and taking up a lot of installation space.In addition, the rotation radius in the case of a disk having a diameter of 450 mm or more when operating the heat exchanger This is long and takes a lot of time to rotate, the disadvantage is that it can not obtain satisfactory thermal efficiency properly.

Therefore, there is a growing trend to improve the heat exchanger that is easy to handle and install by reducing the area and volume of the device while including a more efficient and efficient heat transfer means without existing design restrictions.

The present invention has been devised in view of such a point, and the heat transfer means of the heat exchanger is configured in a drum shape so that the overall size of the device can be compactly constructed while being as compact as possible. In addition, the heat exchange efficiency can be maximized compared to the installation space of the heat transfer means, and the overall maintenance and repair such as replacement or inspection of the heat transfer means can be easily reused, thereby extending the life of the heat exchanger. The purpose is to provide a drum type heat exchanger.

Another object of the present invention is to provide a drum type heat exchanger that can maintain a high heat efficiency by adopting a drum type with a small rotation radius can shorten the overall operating cycle time of the heat exchanger and at the same time ensure sufficient heat transfer area. have.

Hereinafter, described in detail a preferred embodiment of the drum type heat exchanger according to the present invention.

Drum type heat exchanger of the present invention is characterized in that it comprises a drum-type heat transfer means.

The drum-type heat transfer means transmits sensible heat and latent heat energy between two air flows passing therethrough while being rotated by a predetermined driving means.

In addition, the drum-type heat transfer means may be combined with a blocking plate which is arranged in the heat exchanger body and can block mutual mixing between two opposing air flows.

The drum-type heat transfer means comprises a heat transfer medium having sufficient porosity to enable air circulation as well as a density sufficient to introduce turbulence into the air flow and provide a surface area for heat transfer.

For example, polyester particles, glass fibers, nonferrous metals, foamed resins, and the like may be used. Preferably, an appropriate amount of deodorant may be added to remove the smell of the heat transfer medium. A zeolite component can be added to remove bacteria, such as mold.

In this case, when the particles of the polyester particles, glass fibers, non-ferrous metals, etc. are used as the heat transfer medium, a receptor is provided which can be bonded to the surface of the drum-type heat transfer means while accommodating them, and is easy to be molded like the foamed resin. One is provided molded in one piece.

1 is an exploded perspective view illustrating a drum heat exchanger according to the present invention, FIG. 2 is a front sectional view showing a drum heat exchanger according to the present invention, and FIG. 3 is a cross-sectional view taken along line A-A of FIG.

As shown, the heat transfer medium 19d for heat exchange may be installed in a structure surrounding the entire outer circumference of the drum body 19c having a cylindrical shape of a porous network, preferably the heat transfer medium 19d as a whole. After the circumference is wrapped in one piece or the entire circumference is divided into a plurality of zones, it can be installed in a divided type divided into several units that can be assigned to each divided zone one by one.

Split installation as above is advantageous in terms of checking or replacing the heat transfer medium 19d.

For example, when the heat transfer medium 19d is integrally formed like a foamed resin, the exchange and inspection are easier. However, when the heat transfer medium 19d is particulate, as shown in FIG. The heat transfer medium 19d can be installed only by removing or remounting the mesh member 19e, and the inspection and replacement can be facilitated by removing the mesh member 19e. At this time, it is also possible to individually exchange the receptor containing the particulate heat transfer medium (19d).

The heat transfer drum 19 having the heat transfer medium 19d is disposed side by side in the heat exchanger body 17 having a rectangular cylindrical structure in the longitudinal direction, and transversely along the center axis of the heat exchanger body 17. Two blocking spaces are formed by the blocking plate 14 so that heat exchange can be performed while simultaneously covering both spaces.

To this end, the heat exchanger main body 17 has an external air inlet 10 and an internal air inlet 11 facing both sides on the front surface thereof, and an external air inlet 12 and an internal air outlet 13 on both sides, respectively. ) Is formed therein, and the inside of each of the discharge port and the suction port on both sides of the front as a reference position is provided with a blocking plate (14) across the longitudinal direction of the main body, two isolated spaces on both sides, that is, the chamber for external air ( And chamber 16 for internal air.

Accordingly, the heat exchange operation may be performed in the chamber by the heat transfer drum 19 passing through each chamber while the inside of the heat exchanger main body 17 has an opposite flow between the outside air and the inside air.

For example, the outside air flows into the inside through the heat transfer medium 19d positioned on the outside air chamber 15 side through the side outside air inlet 12, and then opens the front outside air outlet 10. It is supplied to the indoor side through the inside, the air inside is introduced into the interior air chamber 16 through the front internal air inlet (11), the heat transfer medium (19d) located on the internal air chamber (15) side It passes through and exits to the outside through the side internal air discharge port 13, wherein the internal and external air is mutually transferred by the heat transfer medium 19d of the heat transfer drum 19 passing between both chambers while staying in each chamber. The latent heat and sensible heat of the liver will be exchanged. That is, fresh air is introduced from the outside without consuming internal heat to the outside, and only the odor escapes to the outside without releasing internal heat.

In this case, the air inlet and the outlet may be selectively installed with the grill, or a duct or a hose extending from an external air blowing means may be connected to induce the flow of air.

A blocking brush 22 is provided by the heat transfer drum 19 as a means for blocking heat transfer between the chambers during the heat exchange action to air in both chambers.

The blocking brush 22 is a contact portion between the blocking plate 14 and the inner circumferential surface of the heat transfer drum 19 blocking both chambers, and the top and bottom plates of the heat exchanger body 17 and the heat transfer drum 19. It is installed at each contact between the outer circumferential surface to completely block the heat transfer between the outer air chamber 15 and the inner air chamber 16, thereby reducing the heat loss as possible to maintain a high thermal efficiency of the heat exchanger.

The heat transfer drum 19 may rotate at a predetermined speed between the chambers so as to perform a heat exchange effect on the air.

To this end, as shown in FIG. 5, the drum body 19c of the heat transfer drum 19 has a roller guide surface 19a and a pulley 19b in the middle of the length, which extend in the circumferential direction at both ends, and the heat exchanger. It is located concentrically in the interior of the main body 17, and the heat transfer medium 19d is coupled between both the roller guide surfaces 19a and the pulley 19b, and each roller guide surface 19a of the heat exchanger main body 17 Four rollers 18 are arranged in a lattice structure that can be idled at the front plate and the rear plate at the same time, and the four rollers are balanced in a balanced manner so that the two rollers can be supported by eight positions. As shown in the drawing, the pulley 19b is connected to the pulley and the belt 20 on the shaft of the drive motor 21 located at one side of the drum body 19c, so that the heat transfer drum 19 is the drive motor 21. Can be rotated by the operation.

At this time, the drive motor 21 is installed using a plate-shaped bracket 24 fixed on the heat exchanger body 17, and the idler (1) of which position is adjustable along the slot 25 on one side of the bracket 24 23 is installed so that the tension of the belt 20 can be adjusted as needed.

Here, the rotational speed of the drive motor, that is, the rotational speed of the heat transfer drum is preferably about 20 to 40rpm per minute.

If the rotational speed of the heat transfer drum is too low, the overall efficiency of the heat exchanger heat exchanger is lowered, and if the rotational speed is excessively fast, crossover or mixing occurs between the flow of air to reduce the ventilation amount, which is provided by the present invention. Heat transfer drum can secure sufficient heat transfer area for heat exchange and its rotation radius is not large. Therefore, even if the rotation speed is maintained faster than the conventional disc heat transfer mat (about 10rpm per minute when the diameter is over 450mm) Excellent effect can be maintained at.

On the other hand, the drum-type heat exchanger in the present invention includes a separate air purifying means including a filter material as a means for purifying the air exiting or entering the inside.

Although the heat transfer medium may also perform a filter function for a predetermined particle and the like, and in particular, may exhibit excellent filtering effect through its own material properties, it may be used in combination with the above separate air purifying means. It is desirable to.

In particular, by providing an air purifying means, for example, a filter material, etc. on the side of the outside air inlet 12 through which outside air flows in, filter out impurities in the outside air, and then supply clean air to the room or to the heat transfer medium. It can purify the air sent.

Adoption of such air purifying means can increase the usability of the drum type heat exchanger more effectively.

The drum type heat exchanger provided by the present invention can be installed and used mainly in windows, etc., and in particular, by extending the ducts or hoses to the outside, it can be used conveniently and conveniently used in the room. It can be installed in various ways.

The heat exchange effect of the drum type heat exchanger provided by the present invention is as follows.

That is, the outside air is introduced from the radial direction of the heat transfer drum 19 to guide its flow in the axial direction, and the inside air is introduced from the axial direction of the heat transfer drum 19 to induce its flow in the radial direction. Heat exchange with the medium is achieved.

The two opposing air streams are formed by the blowing means connected to the inside air inlet 11 and the outside air inlet 12, and pass through the heat transfer drum 19 which rotates continuously. The heat exchange effect of latent heat is performed, and thus, the air discharged to the outside is completely discharged to the outside with the sensible and latent heat deprived, and the air introduced into the air passes through the heat transfer drum 19 and is collected during the discharge of the internal air. Enter the room with the sensible and latent heat deprived.

As described above, the present invention has a simple structure and is easy to handle and install in the overall size or operation method such as the volume and rotational speed of the heat exchanger due to the heat transfer efficiency and material characteristics of the heat transfer medium and the large surface area for heat transfer. It is possible to provide an easy drum type heat exchanger. Therefore, the indoor air can be exchanged with the outside air while performing heat exchange using a heat transfer drum capable of capturing sensible and latent heat and varying the opposite position of the air flow by rotation. Since the ventilation can be performed, efficient indoor air conditioning can be achieved while minimizing heat loss in the room.

As described above, the present invention provides a heat exchanger including a drum-type heat transfer means, thereby increasing the cross-sectional area of the heat transfer medium to secure a sufficient heat transfer area, and to reduce the overall width and volume of the device. This easy advantage and the advantage of not taking up a lot of installation space, and in particular, it is possible to improve the overall performance of the heat exchanger, such as securing a sufficient heat transfer area and shortening the cycle time compared to the number of revolutions per hour, showing excellent heat exchange efficiency There is an advantage.

In addition, since it can be used with a separate air purifying means using a duct connection method, there is an advantage that can be obtained in terms of convenience of the heat exchanger.
