Description

Technical Field

[0001] The invention belongs to the technical field of heat exchangers, and in particular relates to a heat exchanger for cabinet air circulation. Background Art

[0002] Heat exchangers (also called heat exchangers or heat exchange equipment) are devices used to transfer heat from hot fluid to cold fluid to meet specified process requirements. They are an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways. According to their operating process, they can be divided into three categories: partition type, hybrid type, and heat storage type (or heat recovery type); according to the compactness of their surface, they can be divided into compact type and non-compact type.

[0003] The existing cabinet air circulation heat exchanger has a single duct structure and cannot change the air duct in the duct according to the wind speed, so that the wind cannot contact the heat exchange component as evenly as possible. For this reason, we propose a cabinet air circulation heat exchanger. Summary of the invention

[0004] The object of the present invention is to provide a heat exchanger for cabinet air circulation to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a heat exchanger for cabinet air circulation, comprising a fixed plate, a heat exchange component is installed between the two fixed plates, and a conduit is installed inside the fixed plates, a fixed column is installed on the inner wall of the conduit and close to the heat exchange component, and an L-shaped guide plate is movably connected to one side of the fixed column, the L-shaped guide plate is composed of a transverse connecting part and a longitudinal connecting part, and the length of the transverse connecting part is less than the length of the longitudinal connecting part, a connecting ring is installed on the side wall of the L-shaped guide plate corresponding to the fixed column, the connecting ring is sleeved on the outside of the fixed column, and the longitudinal connecting part of the L-shaped guide plate is perpendicular to the axis of the conduit, and torsion springs are installed at both ends of the L-shaped guide plate.

[0006] Preferably, the torsion spring is sleeved on the outside of the fixing column.

[0007] Preferably, one end of the torsion spring is fixedly connected to the L-shaped guide plate, and the other end of the torsion spring is fixedly connected to the inner wall of the conduit.

[0008] Preferably, the L-shaped guide plate and the fixing column are both installed horizontally.

[0009] Preferably, the number of the L-shaped guide plates and the number of the fixing columns are two respectively.

[0010] Preferably, a screw is installed on the outer wall of the fixing plate and located outside the conduit.

[0011] Preferably, the fixing plates are fixedly connected to each other via connecting columns and connecting pieces.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] An L-shaped guide plate is designed and installed inside the duct. Because the length of the transverse connection part is smaller than the length of the longitudinal connection part, when the wind speed in the duct reaches a certain level, the longitudinal connection part of the L-shaped guide plate can be rotated toward one side of the duct axis with the fixed column as the center. At this time, the transverse connection part and the longitudinal connection part can further turbulently diffuse the wind for uniform treatment, and when the wind speed decreases, the L-shaped guide plate will be reset under the action of the torsion spring.

[0023] See also Figure 1-Figure 4 The present invention provides a technical solution: a heat exchanger for cabinet air circulation, comprising a fixed plate 1, a heat exchange component 4 is installed between two fixed plates 1, and a conduit 3 is installed inside the fixed plates 1, a fixed column 8 is installed on the inner wall of the conduit 3 and close to the heat exchange component 4, and an L-shaped guide plate 7 is movably connected to one side of the fixed column 8. The L-shaped guide plate 7 is composed of a transverse connecting part and a longitudinal connecting part, and the length of the transverse connecting part is less than the length of the longitudinal connecting part. A connecting ring 10 is installed on the side wall corresponding to the L-shaped guide plate 7 and the fixed column 8, and the connecting ring 10 is sleeved on the outer side of the fixed column 8, and the longitudinal connecting part of the L-shaped guide plate 7 is perpendicular to the axis of the conduit 3, and torsion springs 9 are installed at both ends of the L-shaped guide plate 7.

[0024] In this embodiment, preferably, the torsion spring 9 is sleeved on the outer side of the fixing column 8 .

[0025] In this embodiment, preferably, one end of the torsion spring 9 is fixedly connected to the L-shaped guide plate 7 , and the other end of the torsion spring 9 is fixedly connected to the inner wall of the conduit 3 .

[0026] In this embodiment, preferably, the L-shaped guide plate 7 and the fixing column 8 are both installed horizontally.

[0027] In this embodiment, preferably, the number of the L-shaped guide plates 7 and the number of the fixing columns 8 are two respectively.

[0028] In this embodiment, preferably, a screw rod 2 is installed on the outer wall of the fixing plate 1 and located outside the conduit 3 .

[0029] In this embodiment, preferably, the fixing plates 1 are fixedly connected to each other through connecting columns 5 and connecting members.

[0030] The working principle and use process of the present invention are as follows: when the device is used, air is taken in by the duct 3 on one side and air is exhausted by the duct 3 on the other side. When the wind passes through the heat exchange component 4, heat exchange can begin. The heat exchange component 4 can be a heat exchange fin, etc. When the wind speed in the duct 3 reaches a certain level, that is, the wind is greater than the elastic force of the torsion spring 9, the longitudinal connection part of the L-shaped guide plate 7 can be rotated toward one side of the axis of the duct 3 with the fixed column 8 as the center. At this time, the tip of the L-shaped guide plate 7 and the pipe mouth of the duct 3 opposite to the duct 3, the transverse connection part and the longitudinal connection part are in a “>” shape, which can further turbulently diffuse the wind, making the wind diffuse in a trumpet shape, so as to evenly contact the heat exchange component 4, thereby further increasing the heat exchange effect, and when the wind speed decreases, the L-shaped guide plate 7 will be reset under the action of the torsion spring 9. When the wind speed is small, that is, the amount of air flowing in the same time is small, turbulent diffusion is not required.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
