It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific protection scope of the present utility model.

[0031] It should be noted that the terms "first", "second", etc. in the description and claims of the present utility model are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence.

[0032] In the description and claims of the present utility model, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0033] An embodiment of the present utility model provides an air heat exchanger structure inside an energy storage converter cabinet, which includes an air inlet structure, a heat exchange structure and an air outlet structure. A wind guiding structure is arranged at the air inlet structure for spreading the incoming air flow, so that the incoming air flow flows into the edge position of the heat exchange structure, achieving the purpose of more sufficient heat exchange.

[0034] The following will, with reference to the accompanying drawings, provide a detailed description of the components of the air heat exchanger structure inside the energy storage converter cabinet provided by the embodiments of the present utility model, as well as the positional relationship and connection relationship between the components.

[0035] As Figures 1 to 5 shown, in the embodiment of the present utility model, the heat exchange coil 5 is arranged inside the heat exchanger housing 1. Among them, a pipe rack 4 is arranged inside the heat exchanger housing 1. The pipe rack 4 is fixedly connected to the inside of the heat exchanger housing 1 and is used to support the heat exchange coil 5. A first connecting pipe 6 is arranged at the inlet end of the heat exchange coil 5, and a second connecting pipe 7 is arranged at the outlet end of the heat exchange coil 5. Both the first connecting pipe 6 and the second connecting pipe 7 pass through one side of the heat exchanger housing 1. For example, as shown in the figure, the first connecting pipe 6 and the second connecting pipe 7 are located at the bottom position on one side of the heat exchanger housing 1.

[0036] The air inlet channel 2 and the air outlet channel 3 are respectively arranged on the heat exchanger housing 1 and are communicated with the inside of the heat exchanger housing 1. The air inlet channel 2, the internal space of the heat exchanger housing 1 and the air outlet channel 3 form a heat exchange channel. The heat exchange coil 5 is located on the air flow path of the heat exchange channel, so that when the air flow passes through the heat exchange channel, it comes into contact with the heat exchange coil 5 to achieve the purpose of heat exchange.

[0037] Specifically, the shape of the heat exchanger housing 1 is rectangular parallelepiped. The air inlet channel 2 and the air outlet channel 3 are located on a group of opposite panels of the heat exchanger housing 1; the area covered by the heat exchange coil 5 is not less than the cross-sectional area of the heat exchange channel. The air flow passing through the heat exchange channel has a certain flow rate. Generally, the air flow directly contacts the part of the heat exchange coil 5 corresponding to the air inlet channel 2, such as the middle part of the heat exchange coil 5. In the technical solution disclosed in this practical embodiment, the air flow direction can be further changed to flow through the area outside the middle part of the heat exchange coil 5, so as to achieve the purpose of more sufficient heat exchange.

[0038] Continue to refer to Figures 1 to 5As shown, in the embodiment of the present utility model, the air guiding structure 8 includes air guiding strips 801. The air guiding strip 801 includes two inclined air guiding surfaces 8011. One ends of the two inclined air guiding surfaces 8011 intersect. The intersecting end of the inclined air guiding surfaces 8011 is the windward end of the air guiding strip 801. The air guiding strip 801 is arranged in the air inlet passage 2. The airflow flowing in the air inlet passage 2 changes its flow direction after passing through the air guiding strip 801.

[0039] That is to say, after the incoming air flow passes through the air guiding strip 801, the air flow is guided to the position corresponding to the end of the inclined air guiding surface 8011, achieving the purpose of changing the air flow direction. In the embodiment of the present utility model, the air guiding structure 8 includes two air guiding strips 801. The two air guiding strips 801 are parallel to each other, and the windward ends of the two air guiding strips 801 are inclined towards the axis direction of the air inlet passage 2. For example, the two air guiding strips 801 are symmetrically arranged with the axis of the air inlet passage 2 as the center. The air flow passing through the two air guiding strips 801 further diffuses towards the edge position, thereby facilitating the air flow to flow to the edge position of the heat exchange coil 5, and thus facilitating the full heat exchange between the air flow and the heat exchange coil 5.

[0040] For example, the air guiding strip 801 is arranged at the end position of the air inlet passage 2. After the air flow changes its direction through the air guiding strip 801, it directly contacts the heat exchange coil 5.

[0041] In the embodiment of the present utility model, the number and arrangement manner of the air guiding strips 801 are not limited thereto. For example, more air guiding strips 801 can be provided, or, for example, multiple air guiding strips 801 can be arranged circumferentially along the inner wall of the air inlet passage 2.

[0042] For example, both ends of the air guiding strip 801 respectively include connecting rods 802; the air guiding strip 801 is fixedly arranged at the inner end of the air inlet of the air inlet passage 2 through the connecting rods 802, such as being connected with the inner wall of the air inlet passage 2 by interference fit or welding through the connecting rods 802. Or, for example, the air guiding strip 801 is a triangular prism, and two faces of the triangular prism are inclined air guiding surfaces 8011. The cross-sectional shape of the air guiding strip 801 can be an equilateral triangle or an isosceles triangle, and its angle and length of the inclined air guiding surface 8011 can also be adjusted according to the specific angle of changing the air flow.

[0043] In the embodiment of the present utility model, air guiding vanes 803 are respectively arranged at the ends of the two inclined air guiding surfaces 8011 far from the windward end; the air guiding vanes 803 extend along the surface where the inclined air guiding surfaces 8011 are located. By arranging the air guiding vanes 803, the air guiding range of the inclined air guiding surfaces 8011 can be extended, and the advantage of strengthening the air diffusion effect can be achieved.

[0044] For example, the air deflector 803 and the air deflector strip 801 are elastically connected by a connecting elastic piece 804. The connecting elastic piece 804 has an arc-shaped structure, and the arched end of the connecting elastic piece 804 protrudes from the surface where the inclined air deflector surface 8011 is located. During the air guiding process, due to the presence of the connecting elastic piece 804, the air deflector 803 blown by the wind will vibrate slightly, which can further disperse the wind. For example, the material of the connecting elastic piece 804 is rubber.

[0045] The embodiment of the present invention further provides an energy storage converter cabinet, including the air heat exchanger structure in the above energy storage converter cabinet. In this energy storage converter cabinet, the air heat exchanger structure includes an air deflector strip 801, which has the advantage of diffusing the wind entering from the air inlet channel 2 at the upper and lower parts of the air outlet, and part of the entering wind blows to the upper and lower parts of the heat exchange coil 5 for sufficient heat exchange; by setting the air deflector 803, it has the advantage of strengthening the air diffusion effect by extending the air guiding range; by setting the connecting elastic piece 804, it has the advantage that under the action of the arc-shaped connecting elastic piece 804, the air deflector 803 blown by the wind will vibrate slightly to further disperse the wind.

[0046] The basic principles, main features and advantages of the present invention have been described above. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
