Description

Technical Field

[0001] The present invention relates to an air circulation system, and more particularly, to a heating module of an air circulation system for purifying and circulating air, so that the air flowing along the circulation can be instantaneously heated for heating purposes. Background Art

[0002] An air circulation system usually installed in buildings, vehicles, etc. is a ventilation system for purifying indoor air or exchanging indoor air with outdoor air to improve indoor air quality.

[0003] Such an air circulation system is used to heat a room and serves as a heater for heating air when supplying purified air or outdoor air into the room.

[0004] Heaters commonly used for heating air are tubular heaters called sheathed heaters or coil-type linear heaters. These heaters are configured to be directly exposed to the air flowing along the circulation. Therefore, in existing air circulation systems, foreign substances such as dust in the air adhere to the surface of the heater and burn at high temperatures, thus generating soot, odors, and even posing a risk of fire caused by ignition.

[0005] To solve these problems, the air purification system operates by installing a filter before the air enters the heater to pre-filter foreign substances such as dust. The method of using a filter to remove foreign substances can prevent the dangers brought by foreign substances, but there is a trouble that the filter must be cleaned or replaced regularly. If the filter is clogged, the air circulation efficiency will decrease, and even cause the heater to heat up rapidly, resulting in damage to the heater itself. This leads to an increase in the installation and operation costs of the air circulation system. Summary of the Invention

[0006] Summary of the Invention. Technical Problems to be Solved The present invention is proposed in view of the above-mentioned many problems, and its purpose is to provide a heating module of an air circulation system that prevents the flowing air from directly contacting the actual heating part of the heater, thereby preventing problems caused by the contact between foreign substances and the heater.

[0007] In addition, the purpose of the present invention is to provide a heating module of an air circulation system that can reduce installation or operation costs by not providing a separate filtering component.

[0008] In addition, the purpose of the present invention is to provide a heating module of an air circulation system that can improve heating efficiency by improving the heat transfer structure.

[0009] Technical Solution To achieve the above object, the heating module of the air circulation system of the present invention is a heating module that is installed on the air circulation flow path of the air circulation system and heats the circulating air.

[0010] In addition, the housing has an area equal to or larger than the area occupied by the heating electrode layer at the position where the heating electrode layer is formed, and a deep part that protrudes toward the flow direction or the direction of the heating electrode layer.

[0011] The heater unit includes a resistance electrode layer, and the resistance electrode layer measures the resistance with temperature by printing a conductive heating material with a predetermined resistance on the outer surface of the housing in an area where the heating electrode layer is not formed.

The heater unit includes: a heating plate that contacts the surface of the housing and dissipates heat over a predetermined area; and a heating electrode layer, a conductive heating material with a predetermined resistance is printed on the surface of the heating plate and generates heat through externally supplied power.

[0013] The housing has an area equal to or larger than the area of the heating plate at the position corresponding to the heating plate, and a deep part that protrudes toward the flow direction or the direction of the heating plate.

[0014] In addition, the deep part formed along the flow direction is inclined or bent relative to the air flow direction.

[0015] In addition, the housing has a plurality of heat dissipation pins, and the heat dissipation pins are formed parallel to the air flow direction and form a predetermined gap on the inner surface where the heater unit is located.

[0016] The heater unit includes a resistance electrode layer, and the resistance electrode layer measures the resistance with temperature by printing a conductive heating material with a predetermined resistance on the surface of the heating plate in an area where the heating electrode layer is not formed. In addition, the resistive electrode layer is made of the same conductive material as that of the heating electrode layer and is configured to selectively serve as a resistive layer or a heating layer.

[0017] Advantageous Effects In the heating module of the air circulation system of the present embodiment, the heater unit is not in direct contact with the flowing air, so damage or malfunction of the heater unit caused by foreign matters such as dust will not occur.

[0022] The present invention and the technical tasks achieved through the embodiments of the present invention will be described by the preferred embodiments described below. Hereinafter, the preferred embodiments of the present invention will be examined in detail with reference to the drawings.

[0023] The differences of the embodiments described below should be understood as not mutually exclusive. That is, without departing from the technical idea and scope of the present invention, the specific shapes, structures, and features described can be implemented in other embodiments related to one embodiment, and in each disclosed embodiment, the positions or arrangements of the respective components can be changed, and similar reference numerals in the drawings represent the same or similar functions in many aspects, and for convenience, the lengths, areas, thicknesses, and their shapes can be exaggerated. In the description of the present embodiment, expressions such as up, down, front, back, first, second, etc. represent relative positions, directions, and orders, and the technical meanings are not limited by the dictionary meanings.

[0024] Figure 1 is a perspective view showing the heating module of the air circulation system according to the present embodiment, Figure 2 is a view showing Figure 1 a cross-sectional view of the heating module, Figure 3 is a view showing Figure 1Partial sectional view of the internal structure of the heating module.

[0025] The air circulation system applied to the heating module of this embodiment can include not only buildings or vehicles, but also various types of systems that forcibly circulate air for the purpose of air purification or heating, such as air purifiers, heating devices, dryers, etc. In addition, the heating module of this embodiment is installed on the air circulation flow path of the air circulation system to heat the circulating air.

[0026] Refer to Figures 1 to 3 , the heating module of this embodiment includes an upper housing 100, a lower housing 200, and a heater unit 300 installed on the surface of the upper housing.

[0027] The upper housing 100 and the lower housing 200 are structures that form the main body of the heating module, are connected to each other and form a channel A through which air flows, and the formed channel A constitutes a part of the flow path for air to circulate in the air circulation system. Therefore, the air circulating in the air circulation system passes through the channel A formed by the upper housing 100 and the lower housing 200 and is heated during this process.

[0028] The combination of the upper housing 100 and the lower housing 200 can form various shapes, such as cylindrical or square tube-shaped. Therefore, the formed flow path A can be circular or square.

[0029] In addition, the upper housing 100 and the lower housing 200 can be composed of separate housings, and can be connected by separate fastening members (not shown), and can also be composed of a single housing that forms an integral body. When the upper housing 100 and the lower housing 200 are composed of an integral housing, they can be divided into the upper housing 100 and the lower housing 200 by imaginary lines respectively.

[0030] In addition, in the description of this embodiment, the heating module is described as the upper housing 100 and the lower housing 200, but depending on the installation position or direction of the heating module, the heating module can also be represented as a left housing and a right housing.

[0031] The upper housing 100 and the lower housing 200 are made of materials with excellent thermal conductivity, for example, they can be made of aluminum plates.

[0032] The heater unit 300 is a heating element installed on the outer surface of the upper housing 100, and is configured to heat the air passing through the internal channel by heating the upper housing 100. The heater unit 300 of this embodiment includes a heating plate 310 that dissipates heat, a heating electrode layer 320 formed on the surface of the heating plate, and a resistance electrode layer 330 formed on the surface of the area that does not overlap with the heating electrode layer 320.

[0033] The heating plate 310 is configured such that the heat generated in the heating electrode layer 320 is dissipated to an area having a predetermined area, and is composed of a plate having a predetermined area, and is bonded to contact the surface of the upper housing 100. In addition, the heating plate 310 is made of a material having excellent thermal conductivity and can be made of a square plate of SUS material as an example.

[0034] The heating electrode layer 320 is a heat source that generates heat by converting electrical energy into heat energy, and is formed by printing a conductive heating paste having a predetermined resistance on the surface of the heating plate 310. The heating electrode layer 320 can be formed in a strip shape having a predetermined width and length in a zigzag pattern, and a pair of first electrode pads 321 in contact with an external power source are provided at both ends thereof, and the first electrode pads 321 are connected to an external power source module (not shown).

[0035] The resistance electrode layer 330 is configured to measure the resistance according to the temperature of the heating plate 310, and a conductive heating paste having a predetermined resistance is printed on the surface of the heating plate 310, that is, on the area between the heating electrode layers 320.

[0036] Since the resistance also generally varies with temperature, the power supplied to the heating electrode layer 320 is controlled by measuring the resistance of the heating electrode layer 320 that varies according to the temperature of the heating plate 310 through the resistance electrode layer 330, so that the heating plate 310 that dissipates heat can be heated to a predetermined temperature. For this purpose, the resistance electrode layer 330 can be formed by printing a conductive paste of the same material as the heating electrode layer 320. Therefore, based on the resistance information measured at the resistance electrode layer 330, it is possible to prevent the heating plate 310 from being heated to a temperature lower than the standard value while preventing the heating electrode layer 320 from quickly generating heat and causing the heating plate 310 to overheat, or while preventing poor heat generation of the heating electrode layer 320, and at the same time, the heating temperature of the air can be controlled.

[0037] The resistance electrode layer 330 can be formed in a strip shape having a predetermined width and length, and a pair of second electrode pads 331 in contact with an external power source are provided at both ends. The resistance electrode layer 330 is connected to an external resistance measurement module through the second electrode pads 331.

[0038] On the other hand, the resistance electrode layer 330 can be used to predict the heating temperature of the heating plate 310 or the air by measuring the resistance of the heating electrode layer 320, but can also be used as another heating electrode layer for heating the heating plate 310. At this time, the external power source module can selectively supply power to the heating electrode layer 320 and the resistance electrode layer 330, or control the heating temperature of the heating plate 310 by supplying power. For this purpose, the resistance electrode layer 330 is composed of a conductive paste of the same material as the heating electrode layer 320 and is formed, for example, in a relatively narrow area different from that of the heating electrode layer 320. The resistance electrode layer 330 is also connected to the external power source module through the second electrode pads 331.

[0039] Since the heating electrode layer 320 and the resistance electrode layer 330 are composed of a conductive paste formed by printing, even if defects occur during the printing process, the printed layer can be cleaned and the heating plate 310 can be reused. Therefore, resource waste caused by defects in the manufacturing process can be minimized, and environmental pollution can be prevented.

[0040] The upper housing 100 includes a deep part 110 and heat dissipation pins 120, such that the air is heated by receiving heat from the heater unit 300 of the above structure, the heat from the heating plate 310 is effectively absorbed, and the absorbed heat is effectively released.

[0041] Refer to Figure 2 and Figure 3 , the upper housing 100 has a deep part 110 protruding into the interior of the passage A through which air flows.

[0042] The deep part 110 is a structure for quickly absorbing and storing the heat from the heating plate 310, and is formed by protruding inward by an amount equal to or greater than the area corresponding to the heating plate 310. That is, the thickness of the deep part 110 is greater than the plate thickness of the surrounding upper housing 100. Therefore, since the heat generated in the heating plate 310 is transferred to the entire area of the deep part volume, a large amount of heat can be transferred.

[0043] In addition, the deep part 110 has a gentle inclination or a curved surface shape with respect to the direction of air movement. Since the deep part 110 protrudes into the interior of the upper housing 100, if it protrudes in a shape similar to a nearly vertical partition wall, the air flow may be disturbed. Therefore, if an inclined or curved shape is formed with respect to the air flow direction, the air flow will not be disturbed.

[0044] In addition, the deep part 110 can be formed to protrude to the outside of the upper housing 100. That is, the deep part 110 protrudes from and is shaped by the upper housing 100, and the heater unit 300 can be mounted on the surface of the deep part 110.

[0045] The upper housing 100 has a plurality of heat dissipation pins 120 formed parallel to the air flow direction. The heat dissipation pins 120 are arranged at a predetermined interval, and narrow channels S in a slit shape are formed between each of the heat dissipation pins 120. The heat dissipation pins 120 greatly increase the area of contact with the air, can quickly heat a large amount of air, and improve the heating efficiency. Therefore, the air flowing between the heat dissipation pins 120 can be quickly heated.

[0046] On the other hand, in the description of the present embodiment, the heater unit 300 shows a structure in which the heating electrode layer 320 and the resistance electrode layer 330 are formed on the surface of the housing via the heating plate 310, but the heater unit 300 can be directly formed on the surface of the housing made of a metal material. That is, the heating electrode layer 320 and the resistance electrode layer 320 can be formed by printing a conductive heating material onto the outer surface of the upper housing 100.

[0047] At this time, the deep part 110 will protrude and be formed in the flow-through direction or the direction of the heating electrode layer with an area equal to or larger than the area occupied by the heating electrode layer 320.

[0048] In this way, in the air circulation system heating module of the present embodiment, by forming the deep part 110 and the heat dissipation pins 120 inside the upper housing 100, the heat absorption from the heater unit 300 and the heat dissipation to the air can be promoted, thereby greatly improving the heating efficiency. In addition, the heater unit 300 is formed on the outer surface of the upper housing 100, and this outer surface is not in direct contact with the air flowing through A, so the heater unit 300 will not be damaged or malfunction due to foreign matters such as dust. Therefore, the heating module of the present embodiment can reduce the installation and operation costs of the air circulation system.

[0049] As described above, the exemplary embodiments of the present invention have been shown and described, but those skilled in the art can make various modifications and other embodiments. These modifications and other embodiments are all considered and included within the scope of the appended claims and do not depart from the true purpose and scope of the present invention.
