New Description: [New Technology Area] This creation is about a roof insulation device for a tin house, especially a roof insulation device that is equipped with a heat absorption unit on the roof to facilitate heat collection and heat dissipation. [Prior Art] According to the "Roof Insulation Structure 0" of the Republic of China New Bulletin No. 471494, its structure is mainly to provide a support frame parallel to the roof and suitable from the roof, and supported by The frame is covered with a heat insulation net, and the disadvantages are as follows: 1. The support frame is exposed, which is easy to oxidize and rust, and has a high damage rate. • 2·Insulation Nete is broken due to sun and rain. 3. When the hurricane comes, the supporting force of the supporting frame is insufficient, and the heat insulation nets fly away because of the wind. 4. The frame of the branch is screwed to the roof of the iron. It can be used for a long time. • It is easy to seep from the screw holes during rain, causing water leakage inside the house. [New content] This creation is not easy to dissipate heat on the roof of the iron house, and the conventional roof insulation structure can not effectively solve the problem of heat dissipation on the roof of the iron house. • The original creation department is a roof insulation device for iron houses. It is provided with an air outlet, an air inlet and a heat absorption unit on the roof. The heat absorption unit is a box made of heat conductive material, and the inside of the box is placed. Phase change heat storage, the box system is fixed inside the roof, and there is a proper gap between the roof and the roof to form the flow channel. 0 M307034 The above air inlet is fixed with louvers. An air exhaust unit is arranged at the air outlet. The above air exhaust unit is an automatic air exhauster. The above exhaust unit is an electric exhaust fan. The casing of the above-mentioned heat absorbing unit is provided with fins on one side of the roof. The phase change heat storage member mentioned above is a paraffin wax. The phase change heat storage member described above is a carboxylic acid ester. The phase change heat storage member described above is a fatty alcohol. The phase change heat storage member described above is a synthetic wax. The phase change heat storage member described above is an ester. This creation has the following advantages: 1. The creation department is set in the house, and the heat absorption unit will not be damaged by the sun and rain, and can be used for a long time without damage. 2. The phase change heat storage part of the creation has the function of adjusting the temperature. When the heat dissipation speed of the sun exposure vent is not fast enough, the phase change heat storage part is not ready to absorb the heat energy, and the heat can be released by the air outlet when the heat is dissipated at night. Discharge to ensure the heat dissipation of the roof of the iron house. 3. The heat dissipation effect can be enhanced by the exhaust unit. 4. Add fins to accelerate the absorption and release of thermal energy. [Embodiment] First, referring to the first and second figures, the first embodiment of the present invention is applied to a double-sided tapered roof (1), which is provided with an air outlet (丨1) and an air inlet (丨2). The air inlet (12) is fixed with a blind (13). 6 M307034 The heat absorbing unit (2) is fixed inside the roof (i) and has a proper gap from the roof (丨) to form a first-class road (21), and the heat absorbing unit (2) is made of heat-conducting material. The box body, the thermal conductive material is iron or inscription, the low-melting phase change heat storage member (22) is placed inside the box body, and the box of the heat absorbing unit (2) is provided with fins on one side of the roof (1) ( 23), increase the contact area with the air to accelerate the absorption and release of the heat month b. In addition, the heat absorbing unit (2) is fixed inside the roof (!), and the light steel frame can be used to construct a grid-like frame. The frame is re-inserted into the thermal unit (2), and the assembly type is not unique. The shape of the heat-absorbing unit (2) can be changed according to the combination of the light steel frame to cope with it. The exhaust unit (3) is located at the exhaust vent (11) to accelerate the exhaust speed to enhance the heat dissipation effect, and the exhaust unit (3) can be divided into an automatic exhaust or an electric exhaust fan. It is an automatic air exhauster. As shown in the third figure, the heat dissipation principle of this creation is convection. When the roof (1) receives sunlight, the air temperature in the flow channel (21) between the roof (1) and the heat absorbing unit (2) rises. The principle of hot air rising causes the hot air to be discharged from the exhaust port # (11), and the air inlet (12) naturally introduces a lower temperature air, that is, convection occurs, and when the convection effect is insufficient to completely release the entire heat energy, The heat absorbing unit (2) conducts heat energy to the phase change storage (22) inside the tank so that heat energy is not introduced into the chamber; and when the night or rain causes the flow path (21) to be lower than the heat absorbing unit (2) When the surface temperature is reached, the phase change heat storage member (22) releases the heat energy, and the released heat energy is discharged by the air outlet (11), and the exhaust unit (3) can accelerate the air discharge speed to enhance the heat dissipation effect. The fourth figure is the second embodiment of the present invention, which is applied to a single-sided tapered roof (1Α), which is also provided with an air outlet (11Α), an air inlet 7 M307034 blind (13A), and also has The heat absorption alone and the efficacy are the same as in the first embodiment, not (12A), and the air inlet (i2A) is fixed with the element (2A) and the exhaust unit (3A) (which will be further described). Moreover, the material of the phase change heat storage member is paraffin, _, fat alcohol, combined «, (four), etc.; and the method for storing and releasing heat energy, taking paraffin as an example, the positive red bell wax is solid, When the temperature rises to the melting point temperature, the paraffin wax gradually dissolves into a liquid state after the heat is absorbed, and when the heat energy is released, the paraffin wax returns from the liquid state to the m state, and the storage is caused by the phase change between the solid and the liquid. The effect of releasing heat. [Simple description of the diagram] The first picture is a plan view of the roof of the double-sided cone. The second figure is a perspective view of the unit of the artificial heat absorption unit. The third picture is a schematic diagram of the convection effect of this creation. The fourth figure is a plan view of a plan view of a second embodiment of the present invention applied to a single-sided tapered roof.
