Technical Field

[0001] This utility model relates to the field of building shading technology, and in particular to an integrated shading device that combines ventilation and cooling. Background Technology

[0002] Building exterior walls get hot when exposed to sunlight, especially in southern regions. After being exposed to the sun, the walls and windows will heat up. Sunlight will shine into the room through the windows, causing the indoor temperature to rise significantly. In order to reduce the significant increase in indoor temperature caused by summer sun exposure, sunshades or awnings are usually installed on the top of the windows. These not only provide shade but also prevent raindrops from falling directly onto the windowsill.

[0003] These types of awnings are designed to prevent direct sunlight from shining through windows, serving only a single purpose.

[0004] Based on this, the present invention designs an integrated sunshade device that combines ventilation and cooling to solve the above problems. Utility Model Content

Detailed Implementation

[0017] Please see Figures 1 to 5 As shown, this utility model provides an integrated sunshade device that combines ventilation and cooling. To better understand the above technical solution, the following will describe the above technical solution in detail with reference to the accompanying drawings and specific embodiments.

[0018] In a specific embodiment of the technical solution of this utility model: Includes air supply duct 1, cover plate 2, and heat exchange box 3; The heat exchange box 3 is a hollow box with an open top. An external vent pipe 12 is installed on the outer wall of the heat exchange box 3. The external vent pipe 12 is connected to the inner cavity of the heat exchange box 3. A filter screen is installed inside the external vent pipe 12. The external vent pipe 12 is a long and narrow ventilation pipe. The air inlet on the outer side of the external vent pipe 12 is opened downward, which effectively prevents rainwater from entering the heat exchange box 3 and plays a role in water isolation.

[0019] The inner wall of the heat exchange box 3 is also covered with a heat insulation pad 31, which is a soft pad made of heat insulation cotton. The heat exchange box 3 has mounting holes on its inner side. The heat exchange box 3 is fixedly installed on the exterior wall of the building by expansion bolts. The inner port of the internal ventilation pipe 32 extends through the exterior wall of the building into the interior of the building, which facilitates the installation of the air supply duct 1 and the filter cover 11 in the interior, and also facilitates the cleaning and maintenance of the air supply duct 1 and the filter cover 11.

[0020] Two internal ventilation pipes 32 are opened on the inner wall of the heat exchange box 3. Each internal ventilation pipe 32 is connected to the interior of the building. Each internal ventilation pipe 32 is equipped with an air valve at its inner opening. The air valve can be a manual valve or an electrically controlled valve, whichever is convenient to operate. The air supply duct 1 is a cylindrical tube with openings at both ends, and a fan is installed inside the air supply duct 1. The air supply duct 1 is sealed and installed on any of the inner ventilation pipes 32, and a filter cover 11 is also installed at the inner end of the air supply duct 1. Each internal ventilation duct 32 is equipped with a filter cover 11 and an air supply duct 1; The internal ventilation duct 32 is connected to the air supply duct 1 or the filter cover 11 by threads; The fan inside the air supply duct 1 is a miniature silent fan; The filter components inside the filter cover 11 include a filter screen and a filter element. The filter element can be detachably installed in the inner cavity of the filter cover 11. The filter element is a high-efficiency filter element or a medium-efficiency filter element of the fresh air system. The filter element filters fine particulate matter and can be easily replaced. The filter element can be filled or integrated into a module and directly installed inside the filter cover 11. The filter screen is fixedly installed on the inner end opening of the filter cover 11, and large particles of dust are intercepted through the filter screen.

[0021] The filter cover 11 is also a cylinder with openings at both ends, and a filter assembly is installed inside the filter cover 11. The cover plate 2 is a flat plate. The cover plate 2 seals and covers the opening at the top of the heat exchange box 3, so that the heat exchange box 3 and the cover plate 2 form an integral sealed cavity. The cover plate 2 is an aluminum alloy flat plate. The bottom of the cover plate 2 is also provided with a snap-fit ​​rib 23. The cover plate 2 is sealed and snapped to the opening of the heat exchange box 3 through the snap-fit ​​rib 23. A rubber sealing ring is also provided between the heat exchange box 3 and the snap-fit ​​rib 23, so that the heat exchange box 3 can be sealed tightly by the cover plate 2. The cover plate 2 and the heat exchange box 3 are also locked with bolts to ensure tight sealing.

[0022] The top of the cover plate 2 is covered with a cooling element 21, which is a reflective radiative cooling film; The cooling element 21 is tightly attached to the top of the cover plate 2, serving the purpose of heat insulation and heat reflection.

[0023] The bottom of the cover plate 2 is provided with multiple fins 22. Each fin 22 is arranged laterally along the inner and outer sides. The multiple fins 22 are parallel to each other and are arranged in the inner cavity of the heat exchange box 3.

[0024] The fins 22 are sheet-like structures made of heat-conducting metal, and multiple fins 22 and the cover plate 2 form a complete heat dissipation plate; The spacing between adjacent fins 22 is the same, and the spacing s between adjacent fins 22 does not exceed 5cm. Each fin 22 is set straight in the inward and outward directions. This allows multiple fins 22 to form an airflow channel. The airflow flows between the fins 22 and can exchange heat with the fins 22, thereby carrying away the heat in the airflow and achieving a cooling effect on the flowing gas. The height gap between the bottom of fin 22 and the bottom of the inner cavity of heat exchange box 3 shall not exceed 3cm.

[0025] It should be noted that: This device can be fixedly installed above the exterior wall of a window, serving as a fresh air circulation system. More importantly, it facilitates heat exchange within the room. Since sunshades are generally not permitted on exterior walls of buildings, this device is primarily used in guesthouses, detached houses, and ground-floor shops in cities. It provides shade and rain protection while also saving energy and cooling the room. Even without using high-powered air conditioners, this device can moderately regulate the indoor temperature, making it particularly suitable for the transition between winter and summer. It eliminates the need for air conditioning while still providing ventilation and heat exchange to cool the room. Because this device continuously cools the room, energy consumption is even lower when air conditioning is used.

[0026] In use, this invention draws in outdoor air through the external vent pipe 12. A matching rubber sealing plug can also be installed on the outside of the external vent pipe 12 to block the opening of the external vent pipe 12. Then, the two air supply tubes 1 are turned on, one to draw in and the other to blow air, which serves to circulate and filter indoor air. In addition, during the air circulation, heat exchange is carried out through the heat exchange box 3 to exchange heat and achieve a cooling effect. In winter, the air valve of the ventilation pipe 32 inside the device needs to be closed. This device only serves to cool in summer.

[0027] This device is primarily used for indoor-outdoor air exchange. Typically, one of these devices is installed at the top of each window to provide shade, cooling, and ventilation.

[0028] In actual operation, when the device on the north side of the building is turned on, the air supply duct 1 draws air outward. The device on the south side of the building is also turned on, but the air supply direction is reversed, drawing outdoor air into the room, thereby achieving the purpose of ventilation and creating appropriate temperature control.

[0029] The inner side of this device refers to the indoor side, and the outer side refers to the outdoor side. The indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
