Description

Technical Field

[0001] The present invention relates to a heat pipe assembly for heating, and more particularly, to a technology of a heat pipe assembly applicable to ondol heating or facility heating, etc. Background Art

[0002] Currently, the heat pipe heating method for ondol can be classified into a hot water type and an electric heating type according to the heat source. The hot water type uses the heat of hot water from the hot water pipe head on one side as the heat source, and the electric heating type uses the resistance heat of an electric heater as the heat source.

[0003] The structure of the heat pipe is as follows: When the heat of hot water or resistance heat is absorbed in the heat absorption part (evaporation part), the internal working fluid vaporizes and moves to the heat dissipation part for heat dissipation. After that, if the condensed liquid working fluid returns to the heat absorption part and absorbs heat again, it vaporizes, and evaporation and condensation are repeated.

[0004] At this time, in the case of a thermo-syphon type heat pipe, it is necessary to have an inclination such that the heat absorption part is lower than the heat dissipation part, so that the working fluid vaporized by absorbing heat in the heat absorption part moves to the heat dissipation part for heat dissipation, and then the condensed liquid working fluid returns to the heat absorption part by itself. The wick type heat pipe uses the capillary phenomenon of the wick formed inside the heat pipe to return the condensed liquid working fluid after heat dissipation to the heat absorption part. Therefore, no inclination is required, and it can be constructed along the horizontal direction.

[0005] In this way, when using a thermo-syphon type heat pipe for ondol heating, an inclination is essential during construction in order for the working fluid to return. Therefore, the disadvantages are that the temperature difference on the surface of the room floor and the amount of finishing mortar increase. In addition, the operator needs to perform piping work of connecting each heat pipe to each hot water pipe head respectively. Therefore, there may be disadvantages such as water leakage at the connected parts that have been piped, and a lot of working time is required.

[0006] Even when constructing ondol heating with an electric heating type heat pipe, wiring work of matching each electric heater with each heat pipe and then connecting the main wire and the electric heater wire is required. Although the connected parts are finished with a shrink tube or the like, there may be disadvantages such as electric leakage in basements due to moisture. Summary of the Invention

[0007] Technical Problem

[0008] An object of the present invention is to provide a heat pipe assembly for heating, which can not only eliminate the causes of disadvantages such as water leakage or electric leakage, but also omit the hot water pipe head in the hot water type and omit the electric heater in the electric heating type, and can shorten the working time.

[0009] Solution to the Problem

[0010] The heat pipe assembly for heating according to the present invention aimed at achieving the above object includes a heat pipe, a heat source, and a heatsink. The heat pipe is configured to repeatedly move the working fluid in the lower internal space, which is evaporated by the heat supplied from the outside lower side and vertically rises, then condenses and vertically descends in a state where it is constructed horizontally and long. The heat source contacts the outside lower side of the heat pipe along the length direction of the heat pipe to supply heat. The heatsink accommodates the heat source in a state of supporting it in contact with the outside lower side of the heat pipe along the length direction of the heat pipe, receives the heat transfer from the heat pipe, and releases the heat to the outside.

[0011] Here, the heat source may be composed of a hot water pipe with hot water flowing inside, or may be composed of a hot wire that generates heat through resistance.

[0012] As one way, the heatsink may include: a heat source accommodating part that has an opening along the length direction on the upper side and wraps the heat source; a heat pipe accommodating part that has an opening along the length direction on the upper side and extends from around both sides of the upper side opening of the heat source accommodating part to wrap the heat pipe; and heat dissipation fins that extend horizontally from around both sides of the upper side opening of the heat pipe accommodating part.

[0013] As another way, the heatsink may include: a heat source accommodating part that has an opening along the length direction on the upper side and wraps the heat source; a heat pipe accommodating part that extends from around both sides of the upper side opening of the heat source accommodating part to wrap the heat pipe; and heat dissipation fins that protrude outward from the heat pipe accommodating part.

[0014] Advantages of the Invention

[0015] In the case where the heat pipe assembly for heating according to the present invention is configured as a hot water type, the hot water pipe head is omitted, so there is no need to perform the operation of directly connecting to the heat pipe. Therefore, not only can the operation time be shortened, but also the causes of drawbacks such as water leakage at the connection part will disappear.

[0016] In the case where the heat pipe assembly for heating according to the present invention is configured as an electric heating type, there is no need to match between the heat pipe and the electric heater, and there is no need to perform wiring work between the main wire and the electric heater wire. Therefore, not only can the operation time be shortened, but also the causes of drawbacks such as electric leakage will disappear.

[0017] Different from the existing heat pipe method, the heat pipe assembly for heating according to the present invention does not require the working fluid to move between the heat absorption part and the heat dissipation part along the length direction of the heat pipe, nor does it require a capillary structure for returning the working fluid in a liquid state after heat dissipation or an inclined construction using its own weight. Therefore, compared with the existing method, heating can be performed more effectively. Brief Description of the Drawings

[0025] The present invention will be described in detail with reference to the accompanying drawings. Here, the same reference numerals are used for the same components, and redundant descriptions and detailed descriptions of well-known functions and components that may unnecessarily obscure the gist of the present invention are omitted.

[0026] The embodiments of the present invention are provided to more completely describe the present invention to those of ordinary skill in the art. Therefore, the shapes and sizes of the respective elements in the drawings may be exaggerated for clearer description.

[0027] Figure 1 is a perspective view of a heat pipe assembly for heating according to an embodiment of the present invention. Figure 2 is for Figure 1 exploded perspective view. Figure 3 is for Figure 1 cross-sectional view.

[0028] Referring to Figures 1 to 3 , a heat pipe assembly 100 for heating according to an embodiment of the present invention includes a heat pipe 110, a heat source 120, and a radiator 130.

[0029] The heat pipe 110 is configured to repeatedly move the working fluid 112 in the inner lower space vertically upward after being evaporated by heat supplied from the outside lower side and then condense and move vertically downward in a state of being horizontally extended and constructed.

[0030] Specifically, the heat pipe 110 is formed by only partially filling the space inside the sealed pipe body 111 with a working fluid 112. The pipe body 111 is formed of a circular pipe body having a certain diameter. The pipe body 111 can be made of various known materials with high thermal conductivity. In addition, the working fluid 112 can be composed of different known types.

[0031] If such a heat pipe 110 is arranged horizontally and long, the working fluid 112 fills a certain height along the length direction of the pipe body 111 in the lower space inside the pipe body 111. In this state, the working fluid 112 absorbs the heat supplied from the lower side outside the pipe body 111 and evaporates, and then after rising vertically, it is deprived of heat and condensed from the upper side part of the pipe body 111. At this time, the upper side part of the pipe body 111 will be heated.

[0032] After that, the condensed working fluid 112 returns to the lower space inside the pipe body 111 by vertically descending due to its own weight. The working fluid 112 effectively heats the upper side part of the pipe body 111 by repeatedly performing the movement of evaporating and rising vertically and then condensing and descending vertically, so that the heat pipe 110 can be used for heating.

[0033] The heat source 120 supplies heat by contacting the outside lower side of the heat pipe 110 along the length direction of the heat pipe 110. That is, the heat source 120 can uniformly transfer heat to the outside lower side of the heat pipe 110 by heat conduction along the length direction of the heat pipe 110.

[0034] As an example, the heat source 120 can be composed of a hot water pipe with hot water flowing inside. The hot water pipe can receive the supply of hot water from a hot water supply source and conduct the heat of the hot water to the outside lower side of the heat pipe 110. Therefore, the heat pipe assembly 100 for heating can be configured to perform heating in a hot water type.

[0035] As another example, the heat source 120 can be composed of a hot wire that generates heat through resistance. The hot wire is formed in a structure where the resistor body is coated with an insulating material. The hot wire can conduct the resistance heat generated when the resistor body receives power supply from a power supply source to the outside lower side of the heat pipe 110. Therefore, the heat pipe assembly 100 for heating can be configured to perform heating in an electric heating type.

[0036] The radiator 130 accommodates the heat source 120 together with the heat pipe 110 in a state of being supported by contacting the outside lower side of the heat pipe 110 along the length direction of the heat pipe 1110. The radiator 130 can hold the heat source 120 in a state of being closely attached to the outside lower side of the heat pipe 110.

[0037] Therefore, the radiator 130 can uniformly conduct the hot water heat or resistance heat of the heat source 120 along the length direction of the heat pipe 110 to the outer lower side of the heat pipe 110. The radiator 130 receives the heat transfer generated from the heat pipe 110 and releases the heat to the outside. The radiator 130 can increase the heat dissipation area and improve the heating efficiency.

[0038] As an example, the radiator 130 may include a heat source accommodation part 131, a heat pipe accommodation part 132, and fins 133. The heat source accommodation part 131 has an opening 131a along the length direction on the upper side and wraps the heat source 120.

[0039] The upper side opening 131a of the heat source accommodation part 131 can expose the upper side part of the heat source 120 to contact the outer lower side of the heat pipe 110. When the periphery of the heat source 120 is circular, the inner surface of the heat source accommodation part 131 is formed into a circular curved surface, so as to be able to contact the periphery of the heat source 120 with the maximum surface area for support. The heat source accommodation part 131 can be formed with a uniform thickness.

[0040] The heat pipe accommodation part 132 has an opening 132a along the length direction on the upper side, and extends from the periphery on both sides of the upper side opening 131a of the heat source accommodation part 131 to wrap the heat pipe 110. The upper side opening 132a of the heat pipe accommodation part 132 can expose the upper side part of the heat pipe 110.

[0041] Therefore, when the heat pipe assembly 100 for heating is constructed for ondol heating, the exposed upper side part of the heat pipe 110 can directly transfer heat to the mortar layer covering its upper part. When the periphery of the heat pipe 110 is circular, the inner surface of the heat pipe accommodation part 132 is formed into a circular curved surface, so as to be able to contact the periphery of the heat pipe 110 with the maximum surface area for support. The heat pipe accommodation part 132 can be formed with a uniform thickness.

[0042] Each fin 133 extends horizontally from the periphery on both sides of the upper side opening 132a of the heat pipe accommodation part 132. When the heat pipe assembly 100 for heating is constructed for ondol heating, each fin 133 can transfer heat to the mortar layer covering its upper part with a wider area. Each fin 133 is in the form of a plate and can be formed with a uniform thickness. The heat source accommodation part 131, the heat pipe accommodation part 132, and each fin 133 can all be formed with the same thickness.

[0043] The radiator 130 is in an integrated form of the heat source accommodation part 131, the heat pipe accommodation part 132, and each fin 133, and it can be made of a known conductive metal material such as aluminum. The radiator 130 can be formed by bending a plate with a certain thickness.

[0044] For the convenience of construction, the radiator 130 can also be divided into multiple parts along the length direction of the heat pipe 110 to accommodate the heat pipe 110 and the heat source 120. As Figure 4 As shown in the figure, the heat pipe assembly 100 for heating of the present embodiment can be constructed in a form in which a plurality of heat pipe assemblies for heating are horizontally arranged on the ondol floor 10 to perform ondol heating.

[0045] In this way, for the heat pipe assembly 100 for heating according to the present embodiment, when it is configured as a hot water type, the hot water pipe head is omitted, so there is no need to perform an operation of directly connecting to the heat pipe. Therefore, not only can the operation time be shortened, but also the causes of drawbacks such as water leakage at the connection part will disappear.

[0046] For the heat pipe assembly 100 for heating according to the present embodiment, when it is configured as an electric heating type, there is no need to perform wiring operation between the heat pipe and the electric heater. Therefore, not only can the operation time be shortened, but also the causes of drawbacks such as electric leakage will disappear.

[0047] In addition, for the heat pipe assembly 100 for heating according to the present embodiment, the heat source 120 is arranged on the lower outer surface of the entire heat pipe 110. Therefore, the working fluid 112 not only absorbs heat quickly, but also performs vertical movement through evaporation and condensation. Therefore, different from the existing heat pipe method, there is no need for the working fluid to move between the heat absorption part and the heat dissipation part along the length direction of the heat pipe, nor is there a capillary structure for returning the working fluid in the liquid state after heat dissipation or an inclined construction using its own weight. As a result, compared with the existing method, the heat pipe assembly 100 for heating of the present embodiment can perform heating more effectively.

[0048] Figure 5 It is a perspective view of a heat pipe assembly for heating according to other embodiments of the present invention. Figure 6 It is for Figure 5 exploded perspective view.

[0049] Referring to Figure 5 and Figure 6 , the heat pipe assembly 200 for heating according to other embodiments of the present invention includes a heat pipe 210, a heat source 220, and a radiator 230.

[0050] The heat pipe 210 and the heat source 220 of the present embodiment can be configured in the same manner as the heat pipe 110 and the heat source 120 of the foregoing embodiment. The radiator 230 of the present embodiment includes a heat source accommodation part 231, a heat pipe accommodation part 232, and heat dissipation fins 233.

[0051] The heat source accommodating part 231 has an opening 231a along the length direction on the upper side and wraps the heat source 220. The upper side opening 231a of the heat source accommodating part 231 can expose the upper side part of the heat source 220 to contact the lower outside of the heat pipe 210. When the periphery of the heat source 220 is circular, the inner surface of the heat source accommodating part 231 is formed as a circular curved surface, so as to be able to support the periphery of the heat source 220 by maximum surface contact. The heat source accommodating part 231 can be formed with a uniform thickness.

[0052] The heat pipe accommodating part 232 extends from around both sides of the upper side opening 231a of the heat source accommodating part 231 to wrap the heat pipe 210. The heat pipe accommodating part 232 wraps the heat pipe 210 in a form where the parts except the opening 231a communicating with the heat source accommodating part 231 are blocked.

[0053] When the periphery of the heat pipe 210 is circular, the inner surface of the heat pipe accommodating part 232 is formed as a circular curved surface, so as to be able to support the periphery of the heat pipe 210 by surface contact. The heat pipe accommodating part 232 can be formed with a uniform thickness. The heat pipe accommodating part 232 and the heat source accommodating part 231 can be formed with the same thickness.

[0054] Each heat sink 233 protrudes outward from the heat pipe accommodating part 232. Each heat sink 233 can include: four first heat sinks 233a, where two of each protrude symmetrically from the heat pipe accommodating part 232 radially to both sides; and two second heat sinks 233b, which are vertically erected on both sides of the heat pipe accommodating part 232 and connect two of the end parts of the first heat sinks 233a respectively. Of course, each heat sink 233 is not limited to the illustrated form, but can be configured in various ways.

[0055] The radiator 230 is in an integrated form of the heat source accommodating part 231, the heat pipe accommodating part 232 and each heat sink 233, and it can be manufactured with a known conductive metal material such as aluminum. The radiator 230 can be formed in a profile manner by extrusion processing or the like. For the convenience of construction, the radiator 230 can also accommodate the heat pipe 210 and the heat source 220 in a form that is divided into multiple parts along the length direction of the heat pipe 210. The heating heat pipe assembly 200 of this embodiment can also achieve the same effects as the heating heat pipe assembly 100 of the previous embodiment.

[0056] As Figures 7 to 10 shown in the figure, the heating heat pipe assembly 200 of this embodiment can be constructed in various ways for facility heating.

[0057] First, as Figure 7 shown in the figure, a plurality of heating heat pipe assemblies 200 can be horizontally arranged and constructed on the upper side inside the plastic greenhouse 20 to heat the entire inside of the plastic greenhouse 20.

[0058] As Figure 8 shown in the figure, the heat pipe assembly 200 for heating can be adjacent to each bed pipe 30 for cultivating crops in the plastic greenhouse respectively and constructed in a horizontally arranged form to perform heating.

[0059] As Figure 9 shown in the figure, a plurality of heat pipe assemblies 200 for heating can be constructed on the ground in the plastic greenhouse in a horizontally arranged form to perform heating. As Figure 10 shown in the figure, a plurality of heat pipe assemblies 200 for heating can be constructed in the floor of the plastic greenhouse in a horizontally arranged form to perform heating.

[0060] Although the present invention has been described with reference to one embodiment shown in the accompanying drawings, this is only an illustration, and those of ordinary skill in the art will understand that various modifications can be made therefrom and there will be other equivalent embodiments. Therefore, the true scope of protection of the present invention should be determined only by the appended claims.
