Description

Energy-saving hot air heater using surface heating element {ENERGY SAVING TYPE FAN HEATER USING NANO TUBE PLANE HEATER}

The present invention relates to an energy-saving hot air heater using a planar heating element, and more particularly, a planar heating element having a large surface area and a tube-shaped planar heating element coated with nanoparticles for heating a heat pipe having high thermal efficiency and transferring it to a heat dissipation fin outside the heat pipe. A heat exchange system for forcibly discharging the heated heat to a blower using blower air to heat the room, forming a hot air heater in which a plurality of heat sources are complementary and organically combined with a planar heating element and a heat pipe,

A blower air flow path is formed by a pipeline in which only a plurality of tube-shaped planar heating elements coated with low power and high efficiency nanoparticles are installed side by side in parallel with high density without additionally installing another heat source, thereby forming a heater that maximizes heat transfer area. Therefore, it is possible to make heat exchange system that maximizes the heat transfer area and minimizes heat loss by simultaneously contacting the heat source through a plurality of planar heating elements that connect air as a heat source having a large surface area and forming an air flow path between the spaces. By forming a warm air heater using a heating element,

The present invention relates to a warm air heater using an energy-saving and environmentally friendly surface heating element of low power consumption that improves the overall thermal efficiency and coefficient of performance of the device by economical and stable heating operation to improve heat exchange capacity and minimize heat loss.

As a representative load device of the air conditioning system, a general fan coil unit is an air conditioner used in a building such as an office building, a hospital, an officetel, a hotel, etc., and is usually a heat exchange coil (cooling and heating coil) and a fan (Fan). ), A filter and a heat source water (such as cold water or hot water) supplied from a refrigerator or a boiler to a heat exchanger including a coil for heat exchange to cool or heat the air, and then to cool the air or warmth. It is designed to heat the room by discharging it into the room by using a blower consisting of a blower fan and a motor.

The fan coil unit is capable of manually controlling the units in each chamber as well as individual control, and the position of the unit is more convenient than the duct method, and the cold and hot water is transferred by a pump, thereby providing air The effect is less than the transfer power.

In recent years, as energy prices have risen, efficient energy use is required to protect natural resources and preserve clean environment.

Effective heat exchange to improve energy efficiency requires the heat exchange time to be quick to minimize the temperature deviation between the different media as quickly as possible, while ensuring the maximum contact area between different media. The load must be reduced for effective heat exchange.

Since conventional heaters directly use electricity, gas, or oil as they are, energy efficiency is very low, and heat pump heaters also have high electrical energy costs.

The conventional fan coil unit has a structure in which heat exchange is not efficient, so there is a problem in that the heating capacity is insufficient compared to the same power and the thermal efficiency is low compared to the same power.

In order to solve the above-mentioned problems of the conventional air conditioner or fan coil unit technology, a heating device technology for efficiently using the energy consumption as much as possible is disclosed.

Heat pipe is an energy-saving heating element that is widely used in various fields. It is a system that generates heat by evaporating the liquid inside the tube. It is a high-tech material that has a thermal conductivity of 1000 times higher than that of copper. As a device that generates heat by evaporating liquid inside as it gets hot, it was first developed as a part for space and aviation, but is widely used as an energy-efficient part such as cooling and heating in cooling of electronic products such as computers.

A working fluid is injected into a vacuum metal tube with a low boiling point and a large evaporation latent heat. The working fluid easily changes from liquid to vapor in low pressure conditions to transfer heat efficiently as latent heat during phase change. On the other hand, the heating fluid (heat medium) is heated by using a common heating heater with low thermal efficiency as a linear heating element, which consumes a lot of energy, increases in size, is very complicated in structure, and frequently causes breakage such as disconnection short circuit. Since the contact surface area of the heating heater (heat source) and the heat pipe is small, the heat transfer efficiency is low, and there is a problem that it is difficult to connect the heat pipe and the heat source.

In addition, the planar heating elements used in all fields of industry have great value in terms of performance and efficiency and are environmentally friendly.

It can be said to be the future technology as a part material through technology establishment.

The heating element is made of cotton, and the surface area for heat exchange is widened, so the heat efficiency is high, and there is no short circuit of the heating element, so long-term use of the heating element is possible, which improves durability, while efficiently combining with the heat pipe heat exchanger or using only the surface heating element However, energy-saving hot air heaters using surface heating elements that have improved heat exchange efficiency by dramatically increasing the heat transfer area have not been developed yet.

Therefore, the present inventors have replaced conventional relatively low-efficiency products such as FCUs, heaters, hot air blowers, and the like, and a conventional fan coil unit-type heating system technology in which a heat pipe heat exchanger is integrated into a case (housing) together with a blower or in a conventional plane. As a result of efforts to comprehensively solve the problems of the combined structure with poor heat exchange efficiency while utilizing the advantages of the warm air heating technology using the heating element, it is eco-friendly and flexible to cope with the energy load due to no pollution. It is to develop a heat pipe heat exchanger using a heating element.

As described above, a fan coil unit (FCU) for a hot air heater of the related art has various problems to be improved.

In replacing the conventional low-efficiency products such as FCU, heater, and hot air heater, in adopting a planar heating element to a fan heater type hot air heater as an energy-saving and environmentally friendly heat source with low power consumption and high efficiency,

The advantage of the heating system technology in the form of a conventional fan heater, while solving the problems in the form of the heating element and heat transfer structure, which lacks the heating capacity compared to the same power and poor heat exchange efficiency compared to the same power,

Developing energy-saving hot air heaters that use environmentally-friendly and energy-saving surface heating elements to safely and rapidly generate heat and increase heat exchange efficiency by increasing the surface area for heat exchange with air to minimize heat loss. There is a technical problem to be done.

The present invention has been made to solve the above problems,

The present invention is an energy-saving hot air heater using a surface heating element to heat the planar heating element by the blower generated by the blower forcibly discharging the heat delivered to the blowing air outside the planar heating element to the blower to perform a comfortable heating of the room In constructing.

A heating element with a large surface area, which is a “⊂” type tube-shaped planar heating element coated with nanoparticles on the surface of a substrate, forcibly discharging heat transferred to a heat dissipation fin outside the heat pipe to a blower using blower air. It is a heat exchange system that performs indoor heating by connecting a planar heating element and a heat pipe as a plurality of heat sources, and a purpose of providing a hot air heater in which a complex heat source is mutually complementary and organically combined.

In addition, low-power, high-efficiency nanoparticles are coated on the surface without additional heat sources, so that only tube-shaped planar heating elements having a large surface area are used as hot air heater heat sources. By forming pipelines with stable arrangements, a blower air flow path is formed between the pipelines, and the blower air is brought into surface contact with a plurality of planar heating elements at the same time, thereby maximizing heat transfer area and minimizing heat loss. Another object is to provide an energy-saving hot air heater that is significantly improved over the technology.

The present invention thus achieved,

Heat pipes on planar heating elements with conductive nano thin films formed on the surface by substituting conventional low-efficiency heating (air-conditioning) products such as FCUs, heaters, and warmers, which have a problem of insufficient heating capacity compared to the same power and poor thermal efficiency compared to the same power. The heat exchange structure is designed to improve heat efficiency by widening the surface area of heat exchange with air. The organic synergistic combination is realized.

In addition, it is possible to intensively dissipate heat with a structure that maximizes the heat transfer area and minimizes the heat loss even if only the tube-shaped planar heating element that can generate heat evenly over a large area has a large surface area without additional heat source. As a result, power consumption is greatly reduced, heat is distributed and radiated evenly, and the heat exchange efficiency is significantly improved compared to the prior art, thereby providing a warm air heater using an energy-saving planar heating element.

Therefore, the energy-saving hot air heater using the surface heating element of the present invention has a higher heat transfer efficiency than the conventional air conditioning (heating) technology, so it is very advantageous for heating of a large space in a small unit as well as energy saving, and at the same time, various products suitable for the installation environment. By selectively adopting, it can meet the needs of customers, it is simple to install, easy to adjust the heating capacity, convenient as a movable structure, and the initial investment can be recovered early.

In particular, it can replace the EHP or GHP market that adopts heat pump type air conditioning technology with high initial installation cost and maintenance cost, and can meet the demand for heating air conditioning in general offices, shops, schools, and public facilities.

Next, the + and-two vertical series power lines 121 are connected in parallel with each of the electrodes 142 arranged horizontally, starting from the lowermost heat pipe of which the power line 121 is grounded with the insulating coating 122. Form

The heat transfer area of the planar heating element 140 is dispersed throughout the heat pipe while partial heat contact is realized between the heat transfer area 140 and the heat transfer layer 140 coated with the "⊂" type nanomaterial, which maximizes the heat transfer area. To form a heat pipe assembly 120 of a plurality of heat source connection structures so as not to waste, thereby improving heat transfer efficiency,

The heat pipe assembly 120 configured as described above is mounted to be inclined in a vertical diagonal direction so as not to be loaded on the flow of air to heat the blower air of the plurality of blower fans 113 mounted on the rear bottom of the heat pipe assembly 120.

Will be implemented.

As described above, the invention according to the first embodiment of the present invention is similar to a conventional fan coil unit (Fan Coil Unit), a heating device having a similar heating function (tentative fan heat pipe unit, Fan Heat pipe Unit or FHU) As an air outlet 111 communicating with a compact sized room, the exterior is formed by a rectangular outer case 110 provided at an upper portion in a grill form, and a "⊂" type nanomaterial coated planar heating element as a heating means ( 140 and the heat pipe 130, the air flow controller 114, the speed control is possible, and the blowing means consisting of the blowing fan 113 driven by the motor 112, respectively, complementary and coupled to each other, the blowing fan at the bottom of the rear An energy-saving hot air heater incorporating a planar heating element and a heat pipe, which is characterized by a comfortable heating and energy-saving heat dissipation structure that rotates 113 to send heat-exchanged warm wind to the room,

Unlike the conventional heat dissipation device, it can serve as a heater as a heat source without the connection of a boiler or a hot water pipe, and also uses the cold water and hot water circulated as a heat source water and uses a loop-type heat pipe ( By using Loop Heat Pipe as a radiator, cooling and heating are possible, which overcomes the problem that conventional FCU uses only cold water and hot water (including steam) as a heat source. As a high efficiency heating element that improves efficiency and reduces energy use costs, it is possible to implement a warm air heater as a heat exchanger in which a planar heating element and a heat pipe are connected.

In the present invention, the heat pipe 120 and the blowing fan 113 having the cap-shaped “⊂” -type nanomaterial-coated planar heating element 140 mounted at one end thereof are embedded in one rectangular rectangular case 110 surrounding them. The upper end of the case 110 is provided with a blowhole 111 communicating with the interior, and by mounting a plurality of heat pipe assemblies 120 simultaneously generating heat to reduce the volume of the heat exchanger unit that supplies heat to the blowing air Can be reduced the size of the warm air heater 100, the blower fan 113, which is driven by the motor 112 and carries air is mounted one or more and the appearance of the case is a fan coil unit (Fan Coil Unit) and As such, the product can be diversified in various shapes, such as floor-mounted, floor-embedded, ceiling cassette-type, ceiling fixed pressure type, ceiling-embedded type, and the like. It can be formed in a space-saving manner regardless of the ceiling height, installation location, use, and conditions.

As the heat pipe heating means (heat source), the "⊂" -type nanomaterial-coated planar heating element 140 is a high-efficiency heating element that has a light and thin cap configuration but has a uniform heat generation without temperature variation and a heat dissipation area per unit volume is expanded. By only partially contacting the “type nanomaterial coated planar heating element 140 at one end of the heat pipe 130, the conduction heat of the planar heating element 140 is rapidly transferred to the heat pipe without wasting heat due to a rapid temperature rise, thereby providing heat transfer efficiency. Formed with a plurality of heat source connection structure to improve the to realize the heat conduction effect is significantly improved energy efficiency compared to the prior art,

The “⊂” type nanomaterial coated planar heating element 140 of the present invention has a neat appearance cap shape in which a conductive nanomaterial coated thin film layer 143 is laminated and coated on a surface of a ceramic “⊂” type ceramic tube 141 as a substrate. to ,

The heat generated by the electrical heating of the planar heating element by the power applied by wrapping and accepting the heat pipe evaporation unit A positioned at one end of the cylindrical heat pipe 130 having high heat generating efficiency to the heat pipe has a high specific surface area. It is configured to deliver efficiently.

As the heating tube formed by stacking the conductive nanomaterial coating thin film layer 143 of the present invention, the “⊂” type nanomaterial coating planar heating element 140 is a thin conductive nanomaterial coating thin film layer 143 unlike a typical linear heating element having low thermal efficiency. Metal electrode 142 formed of +-copper foil on the both ends of the nano-material coating thin film layer 143 at regular intervals, and then coated with an epoxy coating to form an insulating coating 122. Induction current is applied to the conductive nano material coating thin film layer 143 to generate a resistance heat that generates a high resistance value even though it is a short length, and is operated by electricity to discharge fossil combustion products that cause pollution. The heat pipe is heated to the surface in an environmentally friendly way.

As a heating element coated with a conductive nanomaterial coating thin film layer having a predetermined thickness, the "⊂" type nanomaterial coating planar heating element 140 is a heating element that compensates for the disadvantages of the conventional planar heating element coated with a material having a small specific surface area. The nanomaterial to be applied to the invention has a small particle and a specific surface area having a small specific surface area, and thus has a large surface area for heat exchange with air, so that even heat is emitted from the entire surface of the nanomaterial coating thin film layer 143. It has high thermal efficiency and saves energy. It also has excellent electrical conductivity and thermal conductivity, high thermal durability, low thermal expansion coefficient, and light weight properties. It is a functional material and conductive carbon that emits nano-sized far infrared rays and anions. The far infrared radiation emitted from the conductive nanomaterial coating thin film layer of carbon) mixed composition is fast. As long as the work spreads, the residual heat is maintained for a long time, and the electromagnetic wave blocking effect and the heat storage effect are combined, and the synthetic resin polymer is formed to form the insulation coating 122. In addition to the heating element protection function, the epoxy resin provides insulation and insulation effects. It is flexible and has high tensile strength, so it is not easily cut when used, so that no disconnection or short-circuit occurs.

As is well known, heat pipe is a heating element that generates heat by evaporation and condensation without the need for heating wire, and generates heat even by a small heat source, and the heat conductivity of the working fluid is very high energy-saving heating element compared to water.

Heat pipe 120 of the present invention in the form of a straight line (i.e., in the form of an evaporator (A), heat insulation (B), evaporator (A) for absorbing external heat and evaporating the working fluid contained therein; It is installed at predetermined intervals and has a condensation part (C) which is heat dissipated to the outside. A heat dissipation fin 131 is formed and a liquid transport tube for transporting the condensed water condensed in the condensation unit (C) to the evaporation unit (A) on the inner circumference (Wick, porous wick of capillary structure) 134 and A working fluid is included, and the vapor transport pipe 133 is formed in a concentric manner so that the vapor generated in the evaporator A is transferred to the condenser C. As a working fluid, Evaporation unit (A) for receiving evaporation of heat energy of the heat source Condensation part (C) is formed by constituting the passage of vaporization and working fluid and having no heat exchange with the outside. The liquid condensed by the wick 134 repeatedly performs a cycle of returning back to the evaporator A by capillary action to generate heat.

As described above, when the cap-shaped "⊂" -type nanomaterial-coated planar heating element 140 of the present invention is tightly accommodated in the evaporator A and applied to the evaporator A, heat is applied to the working fluid (working fluid: water, Freon refrigerant, ammonia, acetone, methanol, ethanol, etc.) vaporizes and transfers heat to the condensation part (C) through the heat insulating part (B), and the working fluid is liquefied to form a wick ( The heat transfer efficiency is improved by repeatedly returning back to the evaporator A through the passage wall 134.

The reason why the working fluid in the heat pipe 130 is easily evaporated is because the pressure inside the heat pipe is very low in a vacuum state so that the working fluid evaporates even at a low temperature.

In addition, the heat pipe 130 of the present invention has a concentric triple tube structure, the inner part of the cylindrical pipe is a wick (Wick) portion of the working fluid is recovered and the inner cylinder is a passage for moving the working fluid vapor generated in the evaporator to the condenser Function. On the outer surface of the heat pipe, a plurality of heat dissipation fins (Al Fin) 131 having high heat dissipation efficiency are formed at high density on the outer surface of the heat pipe to minimize the amount of bypassed air and improve heat exchange efficiency. Let's go.

In addition, since the heat pipe assembly 120 of the present invention is a stand-alone module that is modularized in a prefabricated manner, it is easy to attach the “⊂” type nanomaterial coated surface heating element 140 and the heat pipe 130 when it is necessary to expand the heating capacity. It can be extended in multiple stages and can be extended by connecting the power supply line 121.

In particular, one of the technical features in the present invention,

Arrange a plurality of heat pipes 130 at a predetermined interval horizontally, insert cap-shaped “⊂” -type nanomaterial-coated planar heating elements 140 in close contact with one end of the horizontally arranged heat pipes, and cover each of the heat pipes 130. The power line 121 for supplying electrical energy is formed such that the power line 121 of + and -2 strands are connected in parallel with each electrode 142 starting from the lowermost heat pipe 130 grounded. ,

The evaporation of the heat pipe 130, which is hundreds times faster than the general linear heating element, in the heat transfer efficiency of the cap-shaped nanomaterial-coated planar heating element 140 that causes the entire heat pipe to generate heat by only partially contacting the evaporation part of the heat pipe. It is attached to the part (A) and has excellent heat transfer efficiency compared to the same area.In addition to the heat source connection structure in which the heat transfer area of the heat pipe is maximized by the planar heating element 140 coated with nano material, the heat dissipation of the heat pipe can be effectively radiated. In order to provide a heat dissipation fin 131 on the outer periphery, the heating capacity can be expanded compared to the same electric power. To form.

The heat pipe assembly 120 is a variable assembly structure capable of expanding the heat pipe 130 as needed. Simple and accurate insertion of the "⊂" type nanomaterial coated planar heating element 140 enables simple, quick and robust assembly and connection, and at the same time, it is fixed to the upper surface of the base end cap-shaped planar heating element 140 by an insulating coating 122 and is short-circuited. The power line 121 is formed to be easily connected to each of the planar heating element 140 and the connection electrode 142 to prevent the external exposure of unnecessary connection member to prevent the heat pipe assembly 120 without bending or uneven surface The surface of the heating element 140 is connected to the overheat prevention circuit (not shown) and is electrically connected to a temperature sensor, and is entirely processed by a computer. It is preferable to operate at a set temperature under the control of an automatically controlled operation panel (controller function), but to control the operation of the manual mode or the automatic mode selectively.

In particular, the heat pipe 130 of the present invention maximizes the heat generation area of the heat dissipation fins 131 vertically and densely arranged, and the heat pipe 130 crosses the inside of the heat dissipation fin 131 on the plate, thereby enabling faster heat treatment. Do.

In addition, the heat pipe assembly 120 having the radiator function configured as described above is inclined in a vertical diagonal direction so as not to be loaded on the flow of air to heat the air of the blower fan 113 mounted on the rear side of the heat pipe assembly 120. By forming a heat exchange structure forcibly exchanging heat by the pipe assembly 120, the heat pipe assembly 120 and the heated air heat exchanged with heat conduction are conducted to the room to improve heat transfer efficiency. (114) is configured to control the use speed in multiple stages.

That is, the blower fan 113 and the heat pipe assembly 120 are arranged side by side in a diagonal direction rather than in the same vertical line to form an S-shaped aeration line (euro) as a flow of a turning curve that maximizes the air flow without being resisted. The pipe assembly 120 diffuses and covers the passage air in the width direction to increase the contact time and contact area of the air and to reduce the by-pass, thereby improving heat exchange efficiency without reducing the blowing capacity. .

Therefore, the present invention is safe with the complementary heat transfer structure of the planar heating element 140, the heat pipe 130, the blowing fan 113, and generates heat quickly with the planar heating element 140 coated with nanomaterials, but excellent thermal efficiency By using the heat pipe 130 to shorten the time required for temperature rise and blowing without pressure or air volume loss to provide a comfortable warm air while saving energy, located below the heat pipe assembly 120 and the motor 112 The heat pipe 130 is heated by the planar heating element to the blower air generated by the blowing fan 113 driven by the air, and the hot heat transmitted to the heat dissipation fin 131 outside the heat pipe 130 is blown with the blowing air and high efficiency. By exchanging heat and forcibly discharging to the air outlet 111 without clogging, it is to perform comfortable heating of the room.

In addition, it is preferable to implement an air purification effect by mounting a filter that can filter the contaminated air at one end of the heat pipe heat exchanger using the planar heating element of the present invention.

Therefore, the present invention primarily receives the heat generated by the planar heating element 140 directly from the evaporation unit A of the heat pipe 130 in direct contact with the planar heating element 140 having a large cap-shaped heat generating area. Heated through the heat pipe 130 to dissipate the warmed heat, and secondly, the heat through the heat pipe 130 is transferred to the blower air of the blower fan 113 to more effectively by the air-to-air heat exchange method Since the heating heat can be discharged through the air outlet 111, the heat loss is minimized and the heat dissipation efficiency is improved, thereby greatly reducing the power consumption. The heat is evenly distributed and dissipated. Significantly reduce energy consumption due to shorter start-up time, significantly shorten standby time due to rapid temperature rise, and dramatically reduce heat exchange efficiency There is an effect to improve.

In addition, in the description of a preferred embodiment of the present invention, since the installation of the exterior case forming the present invention under the window, it was described as an upper discharge type upper discharge type having the advantages of easy piping work, easy installation and good use of the indoor effective space, It can be configured with various models such as an upright type.

The invention according to the second embodiment of the present invention uses only a tubular planar heating element capable of uniformly generating heat over a large area without a heat pipe as an additional heat source as a hot air heater as a heat source, and the heat transfer area is maximized and heat loss. The heat exchange structure is minimized to constitute an energy-saving hot air heater formed to intensively discharge heat.

The invention according to the second embodiment of the present invention is also provided with a blowing fan 113 driven by a motor 112 inside the rectangular outer case 110 provided with the air vent communicating with the room as the invention according to the first embodiment. Energy-saving hot air heater (100) to perform a comfortable heating in the room by forcibly discharging the hot air generated by heating the blown air generated by the planar heating element 140 as a high-efficiency heating element to the grill-shaped blower (111) (100) A part different from the invention according to the first embodiment as a) configuration is a heat exchange structure of the planar heating element 140 alone, which does not use a plurality of heat sources.

That is, the invention according to the second embodiment of the present invention is the same as the invention according to the first embodiment of the plurality of blower fan 113 is driven by the motor 112 in the inner bottom of the rectangular outer case 110 provided with a blower. Equipped,

The outer circumferential surface is formed by a clip-shaped fixing holder 165 in which a pipe-shaped cylindrical tube-shaped nanomaterial-coated surface heating element 170 having a nano-material coating thin film layer 172 formed on a surface thereof corresponds to a male and female pair above the blowing fan 113. It is connected to each other in a wrapped state and firmly fastened with fixing screws 164 to form a planar heating element heat exchange unit 160 as a vertical heating pipeline assembly, and both side ends of the vertical planar heating element heat exchange unit 160 thus formed are plate-shaped.
