As shown in FIG. 1, the heat treatment and painting facility 100 includes a work room 300, such as a booth, which is a space for heat treating or painting a vehicle accommodated by a vehicle, and a temperature transferred to the work room 300 increases. And an intake unit 200 for providing compressed air. The heat treatment and painting facility 100 may further include an exhaust unit 400 for discharging the air of the work room 300 to the outside.

The work room 300 is a place where a vehicle, which is the object of the work, is accommodated in an enclosed space and a worker paints the vehicle or heat-treats the painted vehicle. The upper side or the side of the work room 300 is formed in the work room flow path 310 through which the heat transferred from the intake unit 200 and the temperature of which the temperature rises can be evenly distributed in the work room 300 space. The lower part of the work room 300 is generally provided in a lattice shape, grating, etc., and has a structure in which air can be easily discharged to the entire exhaust floor 400.

The intake unit 200 includes an inflow passage 210 through which inflow air is guided to the work room 300, an intake fan 230 provided on the inflow passage 210 to introduce air, and an inflow of air. And a heat exchanger 250 coupled to a heater 251 that generates heat on the inflow flow path 210 to enable heat transfer, and a heater flow path restricting member 253.

The inflow passage 210 is provided at the rear end portion communicating with the work room 300 through the front end portion and the suction fan 230 flowing into the suction fan 230 and has a rectangular or cylindrical sealed structure. The inflow flow path 210 includes a duct which is a normal air flow path. A damper (not shown) may be provided on the inflow passage 210 to open and close the inflow passage 210.

The suction fan 230 communicates with the inflow passage 210 to provide a flow to the air by the rotational force.

The heat exchanger 250 is provided to allow heat transfer to the air flowing in communication with the inflow passage 210, and the heat exchanger 250 includes a heater 251 and a heater passage restricting member coupled to the heater 251 ( 253).

The heater 251 generates heat to provide heat to the air. The heater 251 may have various shapes and types, but as illustrated in FIGS. 3A and 3B, the heating element 251a including the carbon heating element and the glass tube 251b accommodating the heating element 251a and having a vacuum formed therein. ). The heater 251 has been found to have a better thermal efficiency than a conventional halogen lamp, infrared lamp, etc. through a test.

The heater flow path restricting member 253 may restrict the air flow on the inflow flow path 210 toward the heater 251 on the inflow flow path 210 adjacent to the heater 251. Combined around. The heater flow path restricting member 253 is supported by a housing (not shown) of the heat exchanger 250. The heater flow path restricting member 253 may have a structure in which a cap 253d is formed at an end thereof to disassemble the cap 253d from the outside of the heat exchanger 250 to repair or replace the heater 251 inside. . In the cap 253d, a wiring hole 253f for an electric line or the like to which power can be applied to the heater 251 is formed. In addition, the cap 253d is an engagement means such as a tab in which a fastening means 253e1, such as a bolt, is formed on the cap 253d through a plurality of fastening holes 253e2 formed through both ends of the heater flow path restricting member 253 ( The cap 253d may be engaged with the heater flow path restricting member 253 by engaging with the 253e3. Of course, the fastening means 253e1, 253e2, 253e3 can selectively use a variety of known means.

The heater flow path restricting member 253 may have a cross section of various shapes, for example, a circle, an ellipse, a polygon or a spiral including a triangle as shown in FIG. 5A. For convenience of explanation, hereinafter, only the case where the cross section of the heater flow path restricting member 253 is circular will be described.

The heater flow path restricting member 253 includes a flow path limiting part 253a, in which one of the upstream side and the downstream side of the inflow flow path 210 is provided to restrict contact with the heater 251, and the flow path limiting part 253a. And a flow path opening portion 253b which is in communication with the other and which is opened upstream or downstream of the inflow flow path 210. Here, the case where the flow path restricting portion 253a is formed on the upstream side and the flow path opening portion 253b is formed on the downstream side will be described for convenience of description.

As shown in FIGS. 2 to 4, the flow path restricting part 253a is provided upstream in the direction in which air flows from the heat exchanger 250 (see 'Y' direction in each drawing), and the heater 251 and the air are directly It has a structure that restricts contact. By this structure, the heat emitted from the heater 251 is transferred to the flow path restricting portion 253a, so that heat is transferred to the air contacting the flow path restricting portion 253a. In addition, there is an advantage that the air can be contacted to greatly expand the range of heat transfer.

In addition, the flow path restricting portion 253a may be provided with a through hole 253b formed therethrough so that the air partially introduced may communicate with the heater 251 without being restricted on the inflow flow path 210. Thus, the air on the inflow passage 210 may flow in more various directions.

That is, in the related art, since the air is directly transmitted to the heater 251, a region of heat emitted from the heater 251 is somewhat limited, and heat is removed from the heater 251 itself so that heat is not properly transferred to the air. Eliminate the disadvantages.

A heat reflection part 253k is formed inside or outside the flow path restricting part 253a so as to reflect heat emitted from the heater 251. The heat reflection portion 253k may be formed of a reflective surface such as a glass mirror or may be surface treated on a stainless surface to reflect heat emitted from the heater 251.

The heater flow path restricting member 253 may be used by cutting a pipe or may be used by bending a plate into a required shape.

Accordingly, the heat generated by the heater 251 is dissipated to the flow path opening part 253b, conducts heat at the flow path limiting part 253a, and heat transfers to the air contacting the flow path limiting part 253a, and reflects the heat exchanger. (250) There is an advantage that can be transferred to the air and heat in various forms, such as diverged into the inflow passage 210 inside.

As shown in FIG. 4, heat emitted from the channel opening part 253b of the column X2 may transfer heat to air flowing on the inflow channel 210, and a heat reflection part formed outside the channel limiting part 253a of the column X3. The heat is reflected through the air 253k reflected through the inflow passage 210.

The flow path opening part 253b communicates with the flow path restriction part 253a so that the downstream side of the inflow flow path 210 is opened. The flow path opening part 253b allows the heat emitted from the heater 251 to be directed to the downstream side toward the work room 300 where heat is actually required.

Thus, the heat emitted from the heater 251 may be more effectively and stably transmitted to the air on the inflow passage 210, thereby improving energy efficiency and ultimately saving energy.

The intake unit 200 may be a structure in which the air of the work room 300 is circulated as needed, as well as the outside air is not sucked.

And, as shown in FIG. 4, two heater flow path restricting members 253 are provided in the layer ("X1" layer in FIG. 4, "X2") along the transverse direction (see "X" direction) in the direction in which the inflow air flows. It is preferable to form a "three in the layer and four arranged in the" X3 "layer), and to be arranged in a zigzag form along the direction in which the inflow air flows (see the" Y "direction). Thus, the inlet air and heat transfer can be made in a wider portion. The quantity of the heater 251 is preferably selected in consideration of the size of the work room 300, the external temperature, the kind to be worked.

An operation process of the intake unit 200 having such a configuration will be described below with reference to FIG. 4.

It is assumed that air introduced through the suction fan 230 flows upstream of the heat exchanger 250 and flows downstream of the heat exchanger 250.

In this process, the flow path opening part is in contact with the flow path restricting portion 253a of the heater flow path restricting member 253 or between the heater flow path restricting members 253 so as not to directly contact the heater 251 along the direction in which the inflow air flows. The temperature is increased by receiving heat transfer from the heat dissipated through the 253b to allow air to flow along the inflow passage 210 to the work room 300. On the other hand, the heat emitted from the heater 251 may be reflected through the heat reflection portion 253k provided inside or outside the flow path restricting portion 253a to transfer heat to the air.

Thus, according to the present invention, it is possible to more efficiently transfer heat to the intake air that is rapidly introduced, it is possible to provide an environment in which a heating element that is a heat source that generates heat can sufficiently dissipate heat, and It is possible to provide an intake portion for vehicle heat treatment and painting equipment and a vehicle heat treatment and painting equipment having the same, which can widen the contact area of the battery and give sufficient time for heat transfer.

In addition, the heat transfer function of the heater can be prevented from being lowered due to the intake air, and the structure for improving the heat transfer efficiency can be easily and conveniently used, and the vehicle heat treatment and painting equipment for utilizing the heat reflected during the heat transfer. It is possible to provide an intake portion and a vehicle heat treatment and painting facility having the same.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the invention. will be.
