Description
Technical Field
The invention belongs to the technical field of building engineering, particularly relates to the technical field of energy-saving buildings, and particularly relates to a combined heat pipe system and a building structure applying the same.
Background
The heat pipe utilizes the phase change process of the working medium which is evaporated at the hot end and then condensed at the cold end (namely, the latent heat of evaporation and the latent heat of condensation of liquid) to quickly conduct heat. A typical heat pipe consists of a pipe shell, a wick, and end caps. The interior of the heat pipe is pumped into a negative pressure state and filled with proper liquid, and the boiling point of the liquid can be controlled by the selection of the vacuum degree and the medium, so that the heat pipes with different starting temperatures are obtained. When the temperature of the evaporation section of the heat pipe is higher than the boiling point of liquid, the working liquid in the tube core is heated and evaporated and takes away heat, steam flows to the condensation section of the heat pipe from the central channel and is condensed into liquid, latent heat is released simultaneously, and the liquid flows back to the evaporation section under the action of gravity or capillary adsorption. In this way, a closed cycle is completed, thereby transferring a large amount of heat from the heating section to the heat dissipation section. When the heating section is arranged below, the cooling section is arranged above and the heat pipe is vertically arranged, the back flow of the working liquid can be satisfied by gravity without a wick with a capillary structure, and the heat pipe without the wick with the porous body is called a thermosiphon.
The heat pipe (heat pipe) technology is widely applied to the industries of aerospace, military industry and the like, and is particularly used for enhancing heat exchange. The heat pipe can transfer heat quickly and efficiently, and the heat conduction capacity of the heat pipe can reach tens of times or even hundreds of times of that of metal copper.
In the field of buildings, particularly in areas with hot summer and cold winter, due to the existence of heat inertia of the buildings and the action of solar radiation, the outdoor temperature is higher than that in the indoor part in winter and spring, and the indoor part is still cooler when the outdoor part is warmer. The outdoor heat is quickly and greatly transferred to the indoor, the indoor heat comfort condition can be improved, and the heating energy consumption is reduced. In summer and autumn, some time periods outdoors are cooler, but because of the heat generated by building indoor equipment personnel and the thermal inertia of the building, the indoor temperature is higher than outdoors. At the moment, the indoor heat is quickly transferred to the outdoor, so that the indoor temperature can be reduced, the indoor becomes cool, and the refrigeration energy consumption of the air conditioner is reduced. Existing research has focused primarily on efficient transfer of outdoor solar radiant heat to the interior of a room through heat pipes in winter, without regard to the positive or negative effects of heat pipes in other seasons.

Example 1
As shown in fig. 1, the present embodiment provides a combined heat pipe system 100, which is applied to a building structure 200, wherein the building structure 200 is a wall or a roof of a room. The modular heat pipe system 100 includes: at least one first heat pipe 110, at least one second heat pipe 120, a first pipe 130, and a second pipe 140.
Specifically, in the present embodiment, the first heat pipe 110 is disposed in the building structure 200 in an inclined manner, the evaporation section 111 of the first heat pipe 110 is close to the outer wall of the building structure 200, and the condensation section 112 is close to the inner wall of the building structure 200.
The evaporation section 111 of the first heat pipe 110 is arranged on the outer wall surface side of the wall body or the roof, the condensation section 112 is arranged on the inner wall surface of the wall body or the roof, and the starting temperature is higher than the indoor temperature of the building in the heating season. In the heating season, when the temperature of the building outer wall and the roof outer wall is higher than the indoor temperature due to the irradiation of the sun or the high outdoor temperature, the outdoor heat can be quickly conducted to the indoor space through the first heat pipe 110, otherwise, the heat pipe is not started, and the heat transfer does not occur.
In this embodiment, the condensation section 112 of the first heat pipe 110 is higher than the evaporation section 111. The evaporation section 111 and/or the condensation section 112 of the first heat pipe 110 may be provided with fins for enhancing heat exchange when not affecting the requirements of the wall and roof structure.
The first heat pipe 110 is obliquely arranged in an outer wall and a roof, the evaporation section 111 is lower than the condensation section 112, the end part of the evaporation section 111 of the first heat pipe 110 is positioned on the outer wall surface of the wall, the condensation section 112 is positioned on the inner wall surface, and the evaporation section 111 and the condensation section 112 of the first heat pipe 110 do not extend out of the wall, so that the appearance of the wall is not affected.
In this embodiment, the starting temperature of the first heat pipe 110 is, but not limited to, 10 ℃ to 24 ℃.
The starting temperature of the working medium of the first heat pipe 110 is determined according to the local climate and whether the air-conditioning cooling and heating device is adopted by the building. Taking the hot summer and cold winter areas as an example, according to the indoor thermal comfort standard and the indoor thermal comfort environmental survey, when the building uses less air conditioning cooling and heating equipment, for example, the starting temperature of the first heat pipe 110 is 14 ℃, and when the building uses more air conditioning cooling and heating equipment, for example, the starting temperature of the first heat pipe 110 is 18 ℃.
After the starting temperature of the first heat pipe 110 is determined, the corresponding working medium of the first heat pipe 110 is selected, and the vacuum degree in the first heat pipe 110 is determined according to the relation between the boiling point and the pressure in the thermal physical property parameter of the working medium.
Specifically, in the present embodiment, the first pipeline 130 is connected to the evaporation section 111 of each of the first heat pipes 110, and is used for filling the working medium into the first heat pipe 110 or exhausting the working medium in the first heat pipe 110.
In this embodiment, an interface is reserved in the evaporation section 111 of the first heat pipe 110 and connected to the first pipeline 130, so as to fill or evacuate the working medium to the first heat pipe 110.

In the heating season, when the temperature of the outer wall of the building and the outer wall surface of the roof is higher than the indoor temperature of the room body due to solar irradiation or the outdoor air temperature is higher, when the temperature of the evaporation section 111 of the first heat pipe 110 in the wall or the roof is higher than the boiling point of liquid, the working medium (liquid medium) of the first heat pipe 110 is heated and evaporated to form saturated steam and take away heat, the saturated steam moves from the central channel to the condensation section 112 of the first heat pipe 110 and condenses into liquid droplets, latent heat is released at the same time, and the liquid droplets flow back to the evaporation section 111 under the action of gravity or capillary adsorption. Thus, a closed cycle is completed, so that a large amount of heat is transferred from the evaporation section 111 to the condensation section 112, and the heat outside the room can be quickly transferred to the room through the first heat pipe 110, and when the evaporation section 111 is located at the lower part, the condensation section 112 is located at the upper part, and the first heat pipe 110 is vertically inclined, the backflow of liquid droplets can be satisfied by gravity.
Specifically, in the present embodiment, the second heat pipe 120 is disposed in the building structure 200 in an inclined manner, the evaporation section 121 of the second heat pipe 120 is close to the inner wall of the building structure 200, and the condensation section 122 is close to the outer wall of the building structure 200.
The evaporation section 121 of the second heat pipe 120 is on the inner wall surface of the wall or the roof, the condensation section 122 is on the outer wall surface of the wall or the roof, and the starting temperature is lower than the indoor temperature in the air-conditioning refrigeration season. In the season needing refrigeration, when the temperature of the outer wall of the building and the outer wall surface of the roof is lower than the indoor temperature, the second heat pipe 120 is started, indoor heat can be quickly conducted to the outside through the second heat pipe 120, otherwise, the heat pipe is not started, and heat transfer does not occur.
In this embodiment, the condensation section of the second heat pipe 120 is higher than the evaporation section. The evaporation section 121 and/or the condensation section 122 of the second heat pipe 120 may be provided with fins for enhancing heat exchange when not affecting the requirements of the wall and roof structure.
The second heat pipe 120 is obliquely arranged in the outer wall and the roof, the evaporation section 121 is lower than the condensation section 122, the end part of the condensation section 122 of the second heat pipe 120 is positioned on the outer wall surface of the wall, the evaporation section 121 is positioned on the inner wall surface, and the evaporation section 121 and the condensation section 122 of the second heat pipe 120 do not extend out of the wall, so that the appearance of the wall is not affected.
In this embodiment, the starting temperature of the second heat pipe 120 is, but not limited to, above 25 ℃.
The starting temperature of the working medium of the second heat pipe 120 is determined according to the local climate and whether the air-conditioning cooling and heating device is adopted by the building. Taking a hot-in-summer and cold-in-winter area as an example, according to indoor thermal comfort standard and indoor thermal comfort environment survey, when the building uses less air conditioning cooling and heating equipment, the starting temperature of the second heat pipe 120 is 26 ℃; when the building uses more air to cool and heat, the starting temperature of the second heat pipe 120 is 28 ℃.

In this embodiment, an interface is reserved in the evaporation section 121 of the second heat pipe 120 and connected to the second pipeline 140, so as to fill or evacuate the working medium to the second heat pipe 120. The second pipeline 140 may adopt a PPR pipeline, and the specific pipe diameter is calculated according to the number of the second heat pipes 120. The working medium of the second heat pipes 120 is filled or emptied once a year, and the filling or emptying time can be about 24-48 h, so that each second heat pipe 120 can be filled or emptied with the medium.
The inclination angle of the second heat pipe 120 is determined according to the thickness and structural requirements of the wall body to be applied, and in this embodiment, the included angle between the second heat pipe 120 and the horizontal plane is 30-60 °.

In the present embodiment, the distance between the first heat pipes 110, the distance between the second heat pipes 120, and the distance between the first heat pipes 110 and the second heat pipes 120 are all 20cm to 35 cm. Namely, the distance between the heat pipes is selected to be 20 cm-35 cm.
In the refrigeration season, when the temperature of the outer wall of the building and the outer wall surface of the roof is lower than the indoor temperature, and the temperature of the evaporation section 121 of the second heat pipe 120 in the inner wall surface of the wall or the roof is higher than the boiling point of liquid, the working medium (liquid medium) of the second heat pipe 120 is heated and evaporated to form saturated vapor and take away heat, the saturated vapor moves from the central channel to the condensation section 122 (namely, the outer wall surface of the wall or the roof) of the second heat pipe 120, and is condensed into liquid droplets, latent heat is released at the same time, and the liquid droplets flow back to the evaporation section 121 under the action of gravity or capillary adsorption. Thus, a closed cycle is completed, so that a large amount of heat is transferred from the evaporation section 121 to the condensation section 122, and the indoor heat can be rapidly transferred to the outdoor space through the second heat pipe 120, and when the evaporation section 121 is arranged below, the condensation section 122 is arranged above, and the second heat pipe 120 is vertically inclined, the backflow of liquid droplets can be satisfied by gravity.
In this embodiment, when the first heat pipe 110 is filled with the working medium, the second heat pipe 120 is emptied of the working medium; when the first heat pipe 110 is emptied of the working medium, the second heat pipe 120 is filled with the working medium.
For example, on days 11/15/year to 4/15/year, the first heat pipe 110 is filled with the working medium, and the second heat pipe 120 is emptied of the working medium. The second heat pipe 120 is filled with the working medium and the working medium in the first heat pipe 110 is exhausted from 4 months and 16 to 11 months and 14 days each year.
The first heat pipe 110 and the second heat pipe 120 are respectively filled with working media and emptied through two sets of first pipelines 130 and second pipelines 140 buried in a wall or roof structure: the working medium of the heat pipe is filled during the working period, and the working medium of the heat pipe is emptied during the non-working period, so that the requirement of annual use can be met without a complex control system, and the occurrence of an unreasonable heat transfer process is avoided. Especially, when the heat-insulation air-conditioning system is applied to buildings in hot summer and cold winter areas, heat can be quickly transferred outdoors when refrigeration is needed, and outdoor heat can be quickly transferred indoors when heating is needed indoors, so that the energy consumption of air-conditioning refrigeration and heating can be reduced, and energy is saved.

When the combined heat pipe of the embodiment is adopted on a multi-surface wall body and a roof, pipelines for filling/emptying media can be respectively established on the multi-surface wall body and the multi-surface wall body in a layered mode, or the pipelines are connected to share a storage tank.
That is to say, in this embodiment, the first heat pipe 110 and the second heat pipe 120 may use the same working medium, share a storage tank for storing the working medium, and control to fill the working medium in the storage tank into the first heat pipe 110 through the pump body on the first pipeline 130, or control to empty the working medium in the first heat pipe 110 into the storage tank, and control to fill the working medium in the storage tank into the second heat pipe 120 through the pump body on the second pipeline 140, or empty the working medium in the second heat pipe 120 into the storage tank.
