Description

Technical Field

[0001] This utility model relates to a flow guiding device, and more particularly to a built-in flow guiding device suitable for heat exchangers. Background Technology

[0002] In high-speed rail stations, airports, and the rooftops of residential buildings, where aesthetic design and natural lighting are crucial, glass and other translucent materials are often used in construction. However, in the high temperatures of summer, sunlight causes the interior temperature to rise. To maintain comfort, cooling equipment is needed to regulate the indoor temperature, resulting in significant energy waste.

[0003] Currently, heat exchange devices are installed at locations such as top-transparent glass to cool the glass and reduce the downward transfer of solar heat. However, existing heat exchange devices have excessively high medium flow rates and small contact areas, resulting in low heat exchange efficiency. Therefore, it is necessary to increase the number of medium circulation cycles to meet heat dissipation requirements, leading to higher actual energy consumption.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a built-in flow guiding device suitable for heat exchangers, making it more valuable for industrial applications. Utility Model Content

[0027] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0028] like Figures 1 to 2 The built-in flow guiding device for heat exchangers includes a device body, which is unique in that it has mutually spaced protruding flow guiding mechanisms 1 and concave flow guiding mechanisms 2. Thus, the protruding flow guiding mechanism 1 provides an inner cavity 3, and the concave flow guiding mechanism 2 provides an outer cavity, for facilitating the flow of the heat transfer medium within and between the cavity. To control the flow velocity and achieve effective heat exchange, the protruding flow guiding mechanism 1 has staggered, triangularly arranged finned plates 4. Simultaneously, to meet the requirement of reducing the medium flow velocity, a flow-blocking mechanism is distributed on the inner side of the protruding flow guiding mechanism 1. Furthermore, considering the need for connection with the heat exchanger shell, the device body has several positioning and connecting mechanisms.

[0029] In a preferred embodiment of this invention, the flow-blocking mechanism is a flow-blocking plate 5, the height of which does not exceed half the height of the inner side of the raised flow-guiding mechanism 1. This ensures the slow flow of the medium. Simultaneously, the upper end of the flow-blocking plate 5 has a rounded edge, preventing significant turbulence during medium flow and avoiding improper backflow.

[0030] Furthermore, in order to achieve better medium flow rate, the lateral width of a single piece of the triangular finned plate 4 is 1 to 2 cm, preferably 1.5 cm. Meanwhile, the height of the raised flow guiding mechanism 1 is 0.5 to 1.5 cm, preferably 1 cm.

[0031] In practical implementation, the positioning and connecting mechanism includes an extension edge 6 located at the side end of the device body, and a number of positioning holes 7 are provided on the extension edge 6.

[0032] The working principle of this utility model is as follows:

[0033] This invention is installed inside a heat exchanger. Thus, the protruding flow guiding mechanism 1 has an inner cavity 3, and the concave flow guiding mechanism 2 has an outer cavity. After the inner cavity 3 and the outer cavity are filled with the medium, the medium can contact the device body from all directions, improving the efficiency of heat exchange.

[0034] Meanwhile, the medium is guided by the triangular finned plate 4 to achieve circulation at a low flow rate, further ensuring full contact with the device body and achieving better heat exchange effect.

[0035] In this way, under sufficient sunshine in summer, the heat energy of the sun can be carried away, avoiding excessive heat accumulation under the photovoltaic panels and preventing a significant rise in indoor temperature.

[0036] As can be seen from the above textual description and the accompanying drawings, the present invention has the following advantages:

[0037] 1. It can form independent inner and outer cavities to achieve multi-batch flow of the medium and improve the heat exchange effect.

[0038] 2. The use of triangular finned plates can achieve a significant slow flow of the medium, allowing it to better contact the device body and carry away excess heat.

[0039] 3. A flow-blocking mechanism can be added to further optimize the flow slowing effect.

[0040] 4. It is equipped with a positioning and connecting mechanism, which can be used with screws to securely install it in the heat exchanger.

[0041] Furthermore, the directions or positional relationships described in this utility model are based on the directions or positional relationships shown in the accompanying drawings. They are only for the purpose of facilitating the description of this utility model and simplifying the description, and are not intended to indicate or imply that the device or structure referred to must have a specific orientation, or to operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
