Heat convection building structure

This creation relates to a heat-dissipating convective building structure, especially a heat-dissipating convective building structure that uses the chimney effect to generate natural convection to reduce the internal temperature of the building.

China is at a low latitude tropical or subtropical climate. The sunlight in such areas tends to be strong. When the building is exposed to strong sunlight, it is easy to accumulate the radiant heat of the sun and raise the temperature inside the room, thus improving the air conditioning equipment such as air-conditioning. The use rate, due to the use of electrical cooling will increase the consumption of energy, burning more coal or natural gas will increase carbon dioxide emissions, thereby increasing the greenhouse effect and making the climate hotter. In view of this, in order to achieve the effect of dissipating heat from the building without increasing the amount of carbon dioxide emissions, common methods include: sprinkling water, adding insulation in the building, and the like. However, although the current heat insulating material has the effect of isolating the heat transfer, in the long-term sunshine, the heat energy is accumulated so as to easily exceed the upper limit of the load of the heat insulating layer, so that the indoor temperature rise cannot be suppressed. In addition to water consumption, sprinkling water needs to consume electricity to operate the sprinkler system, and the conventional heat dissipation methods are not ideal.

In order to solve the above problems, the publication No. M489896 discloses a roof heat sink which is suitable for being installed on the roof of a building and includes a plurality of heat dissipating units. Each of the heat dissipating units includes a first heat pipe, a second heat pipe, and a plurality of heat dissipating fins formed on the second heat pipe. The first and second heat pipes communicate with each other to form a heat dissipating space, and have a filling space. Working fluid in the middle. When the roof of the building is exposed to sunlight to generate a high temperature, the second heat pipe laid on the roof conducts thermal energy into the first heat pipe by the working fluid therein, and the plurality of heat radiating fins The heat energy is exchanged with the outside air to condense the working fluid located in the first heat pipe and then drip down, thereby forming an uninterrupted evaporation condensation cycle to lower the roof temperature of the building.

Although the technical solution provided by the above novel patent case can increase the heat dissipation efficiency, when water is used as the fluid, the specific heat of water is greater than that of the building itself, and the heat exchange efficiency is very limited. If a low temperature fluid such as liquid nitrogen is used, it will be in a liquid state. As the temperature of nitrogen rises, it gradually turns into a gas and loses its function. Therefore, how to exhaust the radiant heat accumulated on the building for a long time and effectively without additional energy consumption is an urgent issue in the field.

In addition, the drawings in this creation are not necessarily drawn to scale in order to facilitate the description, and the proportions in the drawings are not intended to limit the scope of the claimed invention.

Regarding the technology of the present creation, as shown in Figures 1-1 and 1-2, the heat-dissipating convection building structure 100 may be a factory, a farmhouse or a general house, and the heat-dissipating convection building structure 100 can be reached. The function of exchanging and cooling the air inside and outside the building. The heat-dissipating convection building structure 100 comprises an inner body 1, an outer body 2 covered by the inner body 1, and a heat-dissipating device 3 extending through the inner body 1 and the outer body 2.

More specifically, the inner body 1 includes a first convection space 10, a plurality of inner walls 11 disposed around the first convection space 10, and an inner roof 12 attached to the top of each of the inner walls 11. The outer body 2 includes a second convection space 20 between the inner body 1 and the outer body 2, and an outer wall 21 disposed around the second convection space 20, and a top portion of each of the outer walls 21 The outer roof 22 and a plurality of vent holes 221 are formed in the outer roof 22. The outer body 2 is constructed of a building material having a heat absorbing and heat-conducting effect, such as concrete or a lacquered steel plate, and covers the inner body 1. The inner body 1 can be an interlayer instead of a heat absorbing material such as concrete or painted steel. The heat insulating building material such as glass fiber and asbestos sheet is provided so that the sunlight does not directly illuminate the inner body 1, and the heat source is quickly distributed to a wider area to increase the temperature in the second convection space 20, In a preferred embodiment, each of the vents 221 is formed at the top end of the outer roof 22, and the hot and cold air exchange speed in the second convection space 20 is made faster by the chimney effect. The heat-dissipating device 3 includes a heat-dissipating tube 30 passing through the inner roof 12 from the top of the outer roof 22, and a venting cover 31 disposed in the first convection space 10 and extending away from the heat-dissipating tube 30, The heat dissipating device 3 constitutes a pair of flow passages 32. When cold air flows in from the opening of the heat exhaust pipe 30 into the roof, the heat exhaust pipe 30 enters the first convection space 10 through the heat exhaust pipe 30. The hot air in the pair of flow spaces 10 is squeezed by the cold air to rise upward and is extruded outside the first convection space 10 along the side edges of the hood 31. In this embodiment, the heat removal device 3 includes at least one louver 33 disposed at an end of the heat exhaust pipe 30 away from the hood 31.

The following is a further description of the flow pattern of the air when the heat convection building structure 100 is exhausted. Referring to Figures 1-3, when the solar radiant heat is applied to the heat convection building structure 100, the external body is raised. The temperature of 2, in turn, heats the air in the second convection space 20, so that air entrained with thermal energy escapes from each of the vent holes 221, and draws colder air at the bottom to fill up, and is cooled by radiant heat. The air will again escape from each of the vents 221, so that the thermal energy accumulated on the outer body 2 is continuously dissipated. In an embodiment, the outer wall 21 is connected to the ground and is provided with an intake valve 211. In order to continuously introduce the cold air close to the ground into the second convection space 20, the hot and cold air in the space continuously flows, and the radiant heat generated by the sun cannot be accumulated on the outer body 2, and the heat convection building structure can be avoided. 100 gradually warmed up.

In addition, when a person performs a heat-generating activity in the heat-dissipating convection building structure 100, for example, when the plant is engaged in the operation of the machine, the temperature in the first convection space 10 is increased, and the indoor air is generated to be hotter than the outdoor. The temperature difference causes the air entrained with thermal energy to rise and escape from the louver 33, while the external cooler air enters the louver 33 and the heat exhaust pipe 30, and diffuses through the hood 31 to the first convection space 10, The hot air in the first convection space 10 is squeezed to follow the side edge of the ventilating cover 31 to float upward again to escape from the louver 33, so that the thermal energy accumulated in the inner body 1 is continuously dissipated to reach The function of continuous exchange of air. Wherein, the ventilation cover 31 is gradually expanded, and the passage cross-sectional area of the ventilation cover 31 is larger than the passage sectional area of the heat exhaust pipe 30, and the physical characteristics of reducing the air flow resistance can be generated, so that the cold air entering from the heat exhaust pipe 30 is generated. It is possible to enter the first convection space 10 more smoothly, increasing the overall air flow rate. In addition, when the overall height of the exhaust convection building structure 100 is higher, the convection effect by the chimney effect is more intense, and the physical characteristics can be utilized to achieve a more efficient air flow effect.

Referring to FIG. 1-3, in an embodiment, the heat exhaust pipe 30 can be set in a telescopic manner, such as a nylon cloth, a polyvinyl chloride material, or a flexible metal. This is not limited. When the temperature difference between the ventilating cover 31 and the outdoor air is small, the convection phenomenon tends to be slow or even stagnant. At this time, the ventilating cover 31 is extended to the ground, and the heat exhaust pipe 30 and the ground are lowered. The air flow impedance between the two makes it easier for the cold air to enter the first convection space 10 and squeeze the hot air, allowing the hot air to drain the heat convection building structure 100 more efficiently.

Referring to Figures 2-1 to 2-2, this is a second embodiment of the heat-dissipating convection building structure 100 of the present invention. The heat-dissipating convection building structure 100 further includes a top portion of the exterior roof 22 The heat dissipating device 4, such as a natural ventilation ball, etc., specifically, the outer roof 22 defines a heat dissipation opening 222. The heat dissipating device 4 includes a spherical blade group 40 disposed outside the heat dissipation opening 222, and a linkage The spherical blade group 40 and the impeller 41 disposed on the heat exhaust pipe 30 can rotate the spherical blade group 40 through the wind and pull the impeller 41 to rotate without additional energy consumption. The air pressure difference between indoors and outdoors is generated to accelerate the hot and cold air exchange rate in the heat convection convection building structure 100, thereby reducing the inflow of hot air from the louver 33 and affecting the inflow of the cold air, thereby improving the heat rejection efficiency of the heat rejection device 3 and reducing Spoiler effect.

Referring to Figures 2-3, the outer wall 21 includes a plurality of external openings 23 that are opened adjacent to the ground. The inner wall 11 includes a plurality of internal openings 13 that are opened adjacent to the ground. The convection building structure 100 further includes a ventilating grille 5 disposed obliquely from the top end of the outer opening 23 toward the top end of the inner opening 13. In the embodiment, when the outer main body 2 is heated by the sun to generate thermal energy, the temperature thereof may be Lifting and indirectly heating the air in the second convection space 20 to escape toward the vent hole 221, and the negative pressure generated by the air loss will suck in the cold air adjacent to the external openings 23 and pass through The gap of the ventilating grille 5 enters the second convection space 20 to generate a circulating convection, which is an effect of continuously releasing the heat of the convective convective building structure 100.

Referring additionally to Fig. 3, the heat-dissipating convective building structure 100 of the present invention can be applied to a type similar to an octagonal building as shown in Fig. 3, whereby the heat-dissipating convection building structure 100 can obtain a source of cold air from all directions. There is no need to make additional inlet and outlet designs for the building.

In summary, the heat convection building structure of the present invention is improved by the principle of air convection, and the prior art uses the sprinkler device to consume additional energy and the heat insulating material does not inhibit the indoor temperature rise for a long time. In addition, the heat-dissipating device of the present invention can be moved in a high and low drop, which can enhance the convection effect of the air, thereby increasing the efficiency of air exchange efficiency.
