Description

rapid heating device

[0001] The present invention relates to a rapid warm-air heating apparatus, which can supply sufficient and rapid hot air to consumers by expanding the heat dissipation area through a narrow area of ​​heating wires without disposing excessive heating wires.

[0002] In general, a hot air device is a device that uses heat generated from a heat source to heat the air and then discharges it to raise the temperature of a desired location (indoors, etc.) by the consumer.

[0003] These hot air devices tend to adopt heating wires that generate heat through electrical resistance as their heat source, and are densely arranged to expose the heating wires to the air passage, and are equipped to discharge heated air to a location or position requiring temperature increase using a blower such as an exhaust fan.

[0004] At this time, the blower is usually placed at the inlet where air is drawn in to minimize the effect of heat by the heating wire. However, if the heating wire is densely placed on the discharge side of the passage through which air is discharged, there is a problem of increasing the power consumption of the blower as air flow resistance occurs.

[0005]

[0006] The present invention has been devised to solve the above-mentioned technical problem, and its purpose is to provide a rapid hot air device that can dramatically increase the heat exchange area by receiving heat from heating wires arranged in a straight line with respect to the direction of air flow.

[0007] In addition, another object of the present invention is to provide a rapid heating device that can minimize air flow resistance and prevent an increase in power consumption of an intake fan by guiding the flow of air using an increased heat exchange area.

[0008] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0009]

[0010] A rapid heating device according to one embodiment of the present invention comprises a heater case having one end and the other end opened so as to form a heating space therein, a heating unit which is an assembly of a plurality of heat exchange panels (hereinafter abbreviated as “heat exchange panels”) for filling refrigerant arranged lengthwise inside the heater case, and a heat supply unit arranged to penetrate the interior of each of the plurality of heat exchange panels in the lengthwise direction, wherein the heating unit is such that the plurality of heat exchange panels are arranged to be spaced apart from each other in the thickness direction inside the heater case.

[0011] Here, the heat supply unit can be placed at either one of the widthwise end and the widthwise end of the heat exchange panel corresponding to the up-down direction of the heater case.

[0012] In addition, the heat exchange panel is made of SUS material, and a phase-changeable refrigerant can be filled in the refrigerant flow space inside.

[0013] Additionally, the refrigerant filled in the refrigerant flow space of the heat exchange panel may include water.

[0014] Additionally, a rear grill cover may be coupled to the opened end of the heater case, and a front grill cover may be coupled to the opened front end of the heater case.

[0015] In addition, the heater case further includes an intake fan arranged at one end, and the intake fan can be arranged between the heating unit and the rear grill cover.

[0016] In addition, the intake fan can suck in external air from the outside of one end of the heater case and cause it to flow through the heating element arranged inside the heater case toward the front grill cover.

[0017] Additionally, the inside of the heater case may further include a lower fixing part and an upper fixing part that mediate the installation of the heating part.

[0018] In addition, a plurality of fixing slits may be formed in the longitudinal direction in the lower and upper fixing parts so that one end in the width direction and the other end in the width direction of the heat exchange panel can be fitted and mounted.

[0019] In addition, the heat supply unit may be arranged to penetrate in the longitudinal direction a widthwise end portion that corresponds to a relatively lower portion with respect to the direction of gravity among one widthwise end portion and the other widthwise end portion of the heat exchange panel.

[0020] Additionally, a heating wire installation groove for installing the heat supply unit can be formed by processing one end of the width direction of the heat exchange panel.

[0021] In addition, the heating wire installation groove can be formed in a groove shape in the thickness direction in the refrigerant flow space of the heat exchange panel in which the refrigerant is filled.

[0022] In addition, the heat supply unit may include an absorber that is elongated in the longitudinal direction, a heating coil wound in a coil shape on the outer surface of the absorber, and a one-side support rubber and an other-side support rubber that support one end and the other end of the heating coil while closing the refrigerant flow space.

[0023] Additionally, the absorbent may be made of a non-woven material or a ceramic paper material.

[0024] In addition, the heating coil can supply heat to the absorber on the inside and supply heat by making surface thermal contact with the heating wire installation groove on the outside.

[0025] In addition, the above-mentioned heater case is placed on the top of a support pole that mediates installation in a space requiring heating, and a blowing angle adjustment unit for changing the blowing direction of the above-mentioned heater case may be provided on the top of the support pole.

[0026] In addition, a control board in the form of a printed circuit board is placed at the bottom of the heater case, and the control board can be shielded by a board shielding cover covering the bottom of the heater case.

[0027]

[0028] According to a rapid heating device according to one embodiment of the present invention, the following various effects can be achieved.

[0029] First, it has the effect of dramatically increasing the heat exchange area and improving heat exchange performance even when heat is supplied through a narrow range of heating wires.

[0030] Second, by minimizing air flow resistance, it not only reduces the power consumption of the intake fan, but also has the effect of raising the temperature of the space requiring heating in a very short time.

[0061]

[0062] Fig. 1 is a virtual diagram showing the application of a rapid heating device according to one embodiment of the present invention, and Fig. 2 is a perspective view (a) and a side view showing an installation example of a rapid heating device according to one embodiment of the present invention.

[0063] A rapid heating device (1) according to one embodiment of the present invention can be installed on the top of a base (B) that mediates fixation to an installation floor surface and a support pole (P) that extends vertically upward with respect to the base (B), as shown in FIGS. 1 and 2.

[0064] Referring to FIGS. 1 and 2, a rapid heating device (1) according to one embodiment of the present invention can be installed in any space requiring heat preservation or heating (hereinafter referred to as a “heating-requiring space”) via a base (B) and a support pole (P). For example, a plurality of rapid heating devices (1) according to one embodiment of the present invention can be installed spaced apart from each other in an interior (room) of a typical house or a corridor or lobby space (see FIG. 1) of a large building (e.g., an airport or a shopping mall).

[0065] However, since warm air (heat) generally naturally moves upwards in a room, it is preferable that the rapid heating air device (1) according to one embodiment of the present invention be installed so that the warm air is discharged at an angle from the upper end of the support pole (P) toward the lower end in order to circulate air at a uniform temperature in a space requiring insulation or heating.

[0066] The support pole (P) serves to mediate the installation of a rapid heating device (1) according to an embodiment of the present invention at the upper end. The upper and lower lengths of the support pole (P) can be manufactured in various length types so that they can be applied differently depending on the space requiring heating in which it is installed. A heater case (10) described later among the components of the rapid heating device (1) according to an embodiment of the present invention can be coupled to the upper end of the support pole (P), and a blowing angle adjustment unit (100) that mediates the coupling of the heater case (10) to the upper end of the support pole (P) can be further provided.

[0067] Here, the blowing angle adjustment unit (100), although not specifically illustrated in the drawing, may be provided so that the blowing direction (or blowing angle) of the rapid heating device (1) according to one embodiment of the present invention with respect to the upper portion of the support pole (P) can be manually or automatically adjusted remotely.

[0068] FIG. 3 is a partial cross-sectional view of a rapid heating device according to one embodiment of the present invention, FIG. 4 is a perspective view showing the front exterior (a) and the rear exterior (b) of the rapid heating device according to one embodiment of the present invention, FIG. 5a is an exploded perspective view of (a) of FIG. 4, and FIG. 5b is an exploded perspective view of (b) of FIG. 4.

[0069] A rapid heating device (1) according to one embodiment of the present invention includes, as referenced in FIGS. 3 to 5b, a heater case (10) having one end and the other end opened to form an air flow passage, a heating unit (50) formed by an assembly of a plurality of heat exchange panels (60, PTX, hereinafter abbreviated as “heat exchange panels”) for filling refrigerant that are arranged lengthwise inside the heater case (10) but spaced apart in the thickness direction, and a heat supply unit (70) arranged in contact with one of one end in the width direction and the other end in the width direction of each of the plurality of heat exchange panels (60) that constitute the heating unit (50).

[0070] The heater case (10) may be formed in a rectangular parallelepiped shape that is substantially hollow and elongated in the longitudinal direction, as shown in FIGS. 3a and 3b. However, it will be appreciated that the heater case (10) need not have a completely rectangular parallelepiped shape, and each corner portion may be connected in a rounded or inclined shape, as shown in FIGS. 3a and 3b.

[0071] In addition, the heater case (10) may be formed such that one longitudinal end (11) and the other longitudinal end (12) are open, and a heat-generating space (10S) may be formed between the one longitudinal end (11) and the other longitudinal end (12). Here, the heat-generating space (10S) may be a concept that includes all areas where the heat exchange area from the heat supply unit (70) is increased by a plurality of heat exchange panels (60). In addition, the heat-generating space (10S) may be defined as a heat exchange space where the outside air flowing into the heater case (10) is heated.

[0072] Outside air (outside air) introduced through one longitudinal end (11) of the heater case (10) is heated by heat transferred to a plurality of heat exchange panels (60) through a heat supply unit (70) in a heating space (10S), and then can be discharged at high speed to a temperature-raising space desired by the user through the other longitudinal end (12) of the heater case (10).

[0073] Here, a pair of installation ribs (16a, 16b) are formed on both left and right ends in the width direction at the bottom of the heater case (10) so that a PCB-type control board (30) can be combined, and after the control board (30) is installed between the pair of installation ribs (16a, 16b), the control board (30) can be shielded and installed from the outside using a board shielding cover (17) provided to cover the control board (30).

[0074] Meanwhile, inside the heating space (10S) of the heater case (10), a lower fixing part (13) and an upper fixing part (14) that mediate the installation of a heating part (50) provided as a group of a plurality of heat exchange panels (60) may be further provided.

[0075] The lower fixing part (13) is arranged on the lower floor surface of the heat generating space (10S) on the side where the above-described control board (30) is installed, and may include a plurality of fixing slits formed long in the front-back direction so that the lower parts of a plurality of heat exchange panels (60) can be fitted and placed.

[0076] Likewise, the upper fixing member (14) is positioned on the upper surface of the heating space (10S) as a surface opposite to the lower fixing member (13), and may include a plurality of fixing slits formed long in the front-back direction so that the upper portions of a plurality of heat exchange panels (60) are fitted and placed thereon.

[0077] Here, a plurality of heat exchange panels (60) are configured to be installed in the heating space (10S) of the heater case (10), and are formed to be long in the longitudinal direction of the front and rear of the heating space (10S), are provided with a slim shape in the thickness direction of the left and right of the heating space (10S), and can be formed to be smaller than the length and larger than the width in the width direction of the upper and lower parts of the heating space (10S).

[0078] A plurality of heat exchange panels (60) can be fixed at one end in the width direction to the lower fixing member (13) and at the other end in the width direction to the upper fixing member (14).

[0079] Meanwhile, a rapid heating device (1) according to one embodiment of the present invention may further include a rear grill cover (20B) and a front grill cover (20A) coupled to an opened end (11) and an open end (12) of a heater case (10), as shown in FIGS. 5A and 5B.

[0080] The rear grill cover (20B) is configured to function as an air intake by being connected to one end (11) of the heater case (10) and the other end (12) that is opened to allow external air (outside air) to flow in from the rear. The rear grill cover (20B) may have a plurality of grill-shaped slot holes (25) formed to allow air to flow in but block the inflow of external foreign substances.

[0081] In addition, the front grill cover (20A) is configured to function as an air discharge unit by being connected to the other end (12) that is opened so that the heated air in the heating space (10S) is discharged forward among one end (11) and the other end (12) of the heater case (10). Similarly to the rear grill cover (20B), the front grill cover (20A) may have a plurality of grill-shaped slot holes (25) formed so that air can be discharged but the inflow of external foreign substances is blocked.

[0082] Fig. 6 is a perspective view showing the internal configuration with the heater case removed from the configuration of Fig. 4 (a).

[0083] According to one embodiment of the present invention, a rapid heating device (1) has a heating unit (50) disposed between a rear grill cover (20B) and a front grill cover (20A), as shown in FIG. 6, and external air introduced through a slot hole (25) of the rear grill cover (20B) is heated while passing through the heating unit (50) provided with a plurality of heat exchange panels (60), and the heated air is discharged to the front where heating is required through the front grill cover (20A).

[0084] Here, the rapid heating device (1) according to one embodiment of the present invention may further include an intake fan (40) arranged to draw in external air from the rear to the inside for temperature increase, as shown in FIG. 6.

[0085] The intake fan (40) is a fan positioned between the open end (rear end) of the heating unit (50) and the rear grill cover (20B), and promotes the inflow of outside air into the heating space (10S) at the rear, while simultaneously inducing air flow toward the front, thereby enabling heat exchange by the heating unit (50) to be smoothly performed in the heating space (10S) inside the heater case (10).

[0086] Here, the intake fan (40) is described as being positioned at the rear end of the heater case (10), which is the portion where air is introduced into the heater case (10) so as to minimize the influence of heat generated in the heating space (10S) as an electrically operated electric field configuration, but the position of the intake fan (40) is not necessarily limited by this. For example, the intake fan (40) may be positioned between the front grill cover (20A) installed at the other end (front end) of the heater case (10) and the heating part (50) within the limit of being able to block the influence of heat generated in the heating space (10S).

[0087] Fig. 7 is an external perspective view showing a heat exchange panel among the configurations of Fig. 2, Fig. 8 is an exploded perspective view of Fig. 7, and Fig. 9 is a perspective view (a) and an exploded perspective view (b) showing a heat supply unit among the configurations of Fig. 7.

[0088] A heating unit (50) for heating external air introduced through the rear grill cover (20B) can be placed in the heating space (10S) of the heater case (10).

[0089] The heating unit (50), as shown in FIGS. 6 and 7, is a combination (assembly) of a plurality of heat exchange panels (60), and the plurality of heat exchange panels (60) are spaced apart from each other by a predetermined distance in the left-right width direction and can be arranged lengthwise in the front-back length direction within the heating space (10S) of the heater case (10). This is to minimize interference with the flow of external air introduced through the rear grill cover (20B) by the heating unit (50).

[0090] In this way, the heat generating unit (50) can play a role in improving the heat exchange performance of the heat supply unit (70) installed in a limited area by expanding the heat exchange area of ​​the heat transferred by the heat supply unit (70) described later to the entire surface area of ​​the heat exchange panel (60). For example, when the heat supply unit (70) is installed at either one of the widthwise end and the widthwise other end of the heat exchange panel (60), the area where the heat transferred by the heat supply unit (70) can be exchanged is expanded to the opposite side of the widthwise end and the widthwise other end of the heat exchange panel (60).

[0091] More specifically, the heat exchange panel (60) can form a refrigerant flow space (65) in which the refrigerant filled therein can flow by mutually joining at least one or more metal base material panels (see reference numerals '61' and '62' of FIGS. 7 and 8), as shown in FIGS. 7 and 8.

[0092] Here, the metal base material panel (see drawing symbols '61, 62') is preferably made of a metal material with excellent thermal conductivity, since the function of the heat exchange panel (60) is to supply heat from the heat supply unit (70) and expand the heat exchange surface area.

[0093] Among the existing metal materials, aluminum (or alloy aluminum) is generally the most preferred material in the relevant technical field due to its excellent thermal conductivity. However, despite the excellent thermal conductivity of aluminum (or alloy aluminum) itself, the types of refrigerants that can be filled inside the material may be limited.

[0094] That is, in the case of a metal base material panel made of aluminum (or alloy aluminum), it is desirable to select a refrigerant that does not chemically react with aluminum (or alloy aluminum), but if water is selected as the refrigerant, a rapid oxidation reaction (chemical reaction) occurs on the surface of aluminum (or alloy aluminum) that comes into contact with water, generating hydrogen, and causing a problem in that the internal pressure (internal pressure) of the refrigerant flow space (65) increases due to the generated hydrogen.

[0095] Accordingly, in the case of a rapid heating device (1) according to one embodiment of the present invention, it is preferable that the material of at least one metal base material panel (see drawing symbols '61, 62') forming the heat exchange panel (60) be SUS (stainless steel) material that hardly causes a chemical reaction with water when the refrigerant is water.

[0096] For reference, in the case where aluminum (or alloy aluminum) is adopted as a material, water must inevitably be excluded as a refrigerant to minimize the chemical reaction described above, and the adoption of expensive refrigerants such as Honeywell refrigerants or other phase-changeable refrigerants that may cause environmental pollution is unavoidable.

[0097] Meanwhile, a rapid heating device (1) according to one embodiment of the present invention may be formed by bonding two SUS material metal base panels (see drawing symbols '61, 62') to form a refrigerant flow space (65) inside the heat exchange panel (60) while maintaining airtightness with the outside.

[0098] Hereinafter, the heat exchange panel (60) forming one of the two SUS material metal base panels for heat dissipation is defined as a one-side heat exchange panel (61), and the heat exchange panel (60) forming the other heat dissipation surface is defined as the other-side heat exchange panel (62).

[0099] One side heat exchange panel (61) and the other side heat exchange panel (62) are formed in a roughly rectangular shape, but have a shape in which some of the four corners are removed in a chamfered shape, and a tube fixing portion (66, 67) to which an air vent tube (68) can be fixed can be formed in the chamfered portion.

[0100] Hereinafter, the sides forming one end and the other end in the longitudinal direction of one side heat exchange panel (61) and the other side heat exchange panel (62) are referred to as 'one side short side' and 'the other side short side', and the sides forming one end and the other end in the width direction of one side heat exchange panel (61) and the other side heat exchange panel (62) are referred to as 'one side long side' and 'the other side long side', and in particular, the side having a relatively short length in the longitudinal direction, which includes a chamfered portion for forming the above-described tube fixing portion (66, 67) among the one side long side and the other side long side, is defined and described as the 'other side long side'.

[0101] For reference, one short side of the heat exchange panel (60) can be defined as the short side on the side where outside air is introduced, the other short side of the heat exchange panel (60) can be defined as the short side on the side where outside air is discharged, one long side of the heat exchange panel (60) can be defined as the lower end fixed to the lower fixing member (13) described above, and the other long side of the heat exchange panel (60) can be defined as the upper end fixed to the upper fixing member (14) described above.

[0102] In addition, the rapid heating device (1) according to one embodiment of the present invention may further include a heat supply unit (70) installed close to one long side corresponding to the lower end of the heat exchange panel (60), as referenced in FIGS. 5 to 7. Here, the heat supply unit (70) may be arranged to penetrate one end in the width direction of the heat exchange panel (60) in the length direction, which is a relatively lower part with respect to the direction of gravity, among one end in the width direction and the other end in the width direction.

[0103] At one end of the width direction of the heat exchange panel (60), a heating wire installation groove (63, 64) for fixed installation of the heat supply unit (70) can be formed by processing. The heating wire installation groove (63, 64) can be formed in a groove shape in the thickness direction in the refrigerant flow space (65) of the heat exchange panel (60) in which the refrigerant is filled. More specifically, the heating wire installation groove (63, 64) can be formed in a groove shape at a portion close to the lower end (one long side) of one heat exchange panel (61) and the other heat exchange panel (62).

[0104] Here, the heat supply unit (70) may include, as referenced in FIGS. 8 and 9, an absorber (71) provided in a longitudinally long rod shape, a heating coil (72) wound in a coil shape on the outer surface of the absorber (71), and a one-side support rubber (73a) and an other-side support rib (73b) that support one end and the other end of the heating coil (72) while closing the refrigerant flow space (65).

[0105] It is preferable that the absorbent (71) be made of a material having a plurality of pores formed therein, through which the refrigerant filled in the refrigerant flow space (65) of the heat exchange panel (60) is easily absorbed and stored.

[0106] Preferably, the absorbent (71) may include a non-woven fabric or ceramic paper material. However, the material of the absorbent (71) is not necessarily limited to the above-described configuration, and may include any material capable of absorbing and retaining liquid refrigerant therein, easily receiving heat from the heating coil (72), and having insulating and heat-resistant properties that are not damaged by the heat.

[0107] The heating coil (72) may be provided with a material capable of generating a predetermined amount of heat by electrical resistance. That is, when current is applied to one side of the heating coil (72), it is converted into a predetermined amount of heat energy by the electrical resistance properties of the heating coil (72), and the converted heat serves to vaporize the liquid refrigerant filled in the refrigerant flow space (65).

[0108] Here, the heating coil (72) can supply heat to the absorber (71) on the inside and to the heating wire installation groove (63, 64) on the outside by making surface thermal contact with it.

[0109] Meanwhile, when installing a heat exchange panel (60) in the heating space (10S) of the heater case (10), it is preferable that the lower end (one long side), which is the side equipped with the heating coil (72), be positioned and installed so as to be located lower relative to the direction of gravity than the upper end (the other long side).

[0110] Here, when one end (72a) of the heating coil (72) is an input end where electricity is input, and the other end (72b) of the heating coil (72) is an output end where electricity is output, at least one end (72a) and the other end (72b) of the heating coil (72) can be extended a predetermined length further outside the refrigerant flow space (65) so as to be connected to an external power cable (not shown).

[0111] The one-side support rubber (73a) and the other-side support rubber (73b) penetrate the heating coil (72) so that one end (72a) and the other end (72b) are exposed to the outside, and the role of closing the refrigerant flow space (65) at both ends of the heating coil installation groove (63, 64) to make it waterproof.

[0112] According to a rapid heating device (1) according to one embodiment of the present invention having such a configuration, a current is applied to a heating coil (72) to generate a predetermined amount of heat, and the heat generated here evaporates the liquid refrigerant that is absorbed and stored through an absorber (71) positioned relatively lower in the direction of gravity in the refrigerant flow space (65), and the evaporated gaseous refrigerant spreads throughout the refrigerant flow space (65) to transfer heat, so that the entire heat exchange panel (60) can expand to a heat exchange surface area with the outside air (outside air).

[0113] Accordingly, since there is no need to densely arrange the heating coils (72) on the air flow path through which the outside air and the heated air flow, it provides the advantage of minimizing the air flow resistance. In addition, even when water is used as a refrigerant, the metal base material panel (see drawing symbols '61, 62') forming the heat exchange panel (60) can be selected from SUS material that does not cause a chemical reaction, and since it can secure heat transfer performance equivalent to that of the existing aluminum (or alloy aluminum) material, the performance of the product can be greatly improved.

[0114]

[0115] Above, a rapid heating device (1) according to one embodiment of the present invention has been described in detail with reference to the attached drawings. However, the embodiments of the present invention are not necessarily limited to the above-described embodiments, and it will be understood that various modifications and equivalent implementations are possible by those skilled in the art to which the present invention pertains. Therefore, the true scope of the present invention is defined by the claims set forth below.
