Description

Technical Field

[0001] The utility model relates to the technical field of battery energy storage, in particular to a heat dissipation cooling air duct with adjustable flow rate and a control system. Background Art

[0002] With the development of the energy storage industry, the number of battery clusters arranged side by side in energy storage containers is increasing. Since the battery clusters will generate a certain amount of heat during operation, the heat density in the energy storage container is also increasing. Therefore, it has always been a difficult problem to be solved to ensure that the energy storage container is always maintained in a reasonable temperature range during actual operation and to ensure that the temperature of all battery clusters remains consistent.

[0003] Most existing energy storage containers use air conditioners as refrigeration devices, that is, the cold air blown out by the air conditioner flows to the corresponding battery cluster through the air outlets opened on the air duct, thereby dissipating the heat from the surface of the battery cluster.

[0004] Taking into account the Bernoulli phenomenon in the air duct (that is, when the wind speed is too fast, the pressure is too small, the amount of cold air entering is reduced, and when the wind speed is slow, the pressure is larger, which increases the amount of cold air entering), the battery cluster close to the air inlet of the duct has a higher temperature than the battery cluster far away from the air inlet of the duct, affecting the temperature uniformity inside the energy storage container.

[0005] At the same time, because the air output of each air source is different, the fixed control device cannot adapt to the air output of each air source. Utility Model Content

[0006] In view of the Bernoulli phenomenon existing in the above-mentioned or existing air ducts, which causes the battery clusters close to the air inlet of the air duct to have a higher temperature than the battery clusters far from the air inlet of the air duct, and the problem of poor temperature uniformity inside the energy storage container, the present utility model is proposed.

[0007] Therefore, the purpose of the present invention is to provide a heat dissipation cooling air duct with adjustable flow rate.

[0008] In order to solve the above technical problems, the utility model proposes the following technical solutions: a heat dissipation cooling air duct with adjustable flow, comprising a main body component consisting of an air duct, an air supply port and an air outlet, and an adjustment component consisting of a built-in adjustment component and an air outlet control component, the air supply port and the air outlet are arranged on the air duct, the built-in adjustment component is arranged in the air duct, and the air outlet control component is arranged on the air outlet.

[0009] As a preferred solution of the utility model of the heat dissipation cooling air duct with adjustable flow, wherein: the built-in adjustment part includes an air guide plate, the width of the air guide plate corresponds to the inner diameter of the air duct, the air guide plate is obliquely arranged in the air duct and ensures that the cavity formed with the air duct is larger at one end close to the air supply port.

[0010] As a preferred solution of the heat dissipation cooling air duct with adjustable flow rate of the utility model, one end of the air guide plate is movably connected to the air duct, and the other end is connected to a hydraulic rod arranged in the air duct.

[0011] As a preferred solution of the heat dissipation cooling air duct with adjustable flow rate of the utility model, wherein: the air guide plate is also provided with an elastic member and a resistance end, the elastic member is arranged in a groove opened in the air guide plate, one end of the resistance end is fixedly connected to the elastic member, and the other end resists against the inner wall of the air duct.

[0012] As a preferred solution of the heat dissipation cooling air duct with adjustable flow rate of the utility model, wherein: the end of the abutting end abutting against the air duct is configured as a semi-cylindrical shape.

[0013] As a preferred solution of the heat dissipation cooling air duct with adjustable flow rate of the utility model, the air outlet control component includes an air outlet pipe and a mesh plate, the air outlet pipe is fixedly connected to the air outlet, and the mesh plate is fixedly connected to the air outlet pipe.

[0014] As a preferred solution of the utility model of the heat dissipation cooling air duct with adjustable flow, the air outlet pipes are evenly distributed on one side of the air duct close to the battery cluster, and the opening rate of the mesh plate gradually decreases from one end of the air outlet of the air duct to the other end.

[0015] The beneficial effects of the utility model are as follows: the scheme cooperates with the main component and the adjustment component, utilizes the air outlet control component to control the air outlet from each part with different wind speed and pressure, adjusts the air volume and thus ensures the uniform temperature of the battery rack, and utilizes the built-in adjustment component to adjust the air volume of each air outlet, thereby adjusting the air volume of the air outlet and ensuring the uniform temperature of the battery rack.

[0016] In view of the problem that the air output of each wind source in the above-mentioned or existing air duct is different, and the fixed control device cannot adapt to the air output of each wind source, the present utility model is proposed.

[0017] In order to solve the above technical problems, the utility model also provides the following technical solutions: a control system, including a monitoring and control unit composed of a temperature sensor, a hydraulic controller and a control terminal, wherein the temperature sensor is arranged on the battery rack, the hydraulic controller is arranged in the air duct and cooperates with the built-in adjustment part.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1 to Figure 3 , which is the first embodiment of the utility model, and this embodiment provides a heat dissipation cooling air duct with adjustable flow rate. The heat dissipation cooling air duct with adjustable flow rate includes a main body component 100 consisting of an air duct 101, an air supply port 102 and an air outlet 103, and an adjustment component 200 consisting of a built-in adjustment component 201 and an air outlet control component 202.

[0034] Specifically, the air supply port 102 and the air outlet 103 are arranged on the air duct 101. Cold air is delivered into the air duct 101 from the air supply port 102 by the fan, and enters the battery rack through the air outlet 103 to cool down the battery cluster. The built-in adjustment component 201 is arranged in the air duct 101, and the air outlet control component 202 is arranged on the air outlet 103.

[0035] Specifically, the built-in adjustment part 201 includes an air guide plate 201a, the width of which is slightly smaller than the inner diameter of the air duct 101, so as to ensure that the air guide plate 201a can move in the air duct 101, but still has a certain degree of sealing. The air guide plate 201a is tilted in the air duct 101 and ensures that the cavity formed with the air duct 101 is larger at the end close to the air supply port 102, so that the capacity of the air duct 101 close to the air supply port 102 is greater than the capacity of the air duct 101 far away from the air supply port 102, which can effectively avoid the Bernoulli phenomenon, that is, the wind speed near the air supply port 102 is faster, resulting in a small wind speed pressure at the air outlet 103 near the air supply port 102, resulting in a small air volume entering the air outlet 103, which causes the battery cluster near the air supply port 102 to have a higher temperature than the battery cluster far away from the air supply port 102.

[0036] Furthermore, one end of the air guide plate 201a is movably connected to the air duct 101, and the other end is connected to a hydraulic rod 201b disposed in the air duct 101. By adjusting the hydraulic rod 201b, the state of the air guide plate 201a in the air duct 101 is adjusted, and the size of the wind cavity of the air duct 101 away from the end of the air supply port 102 is adjusted, so that the device can meet the temperature uniformity requirements for the battery cluster under different wind speeds and wind sources.

[0037] Preferably, an elastic member 201a-1 and a resistance end 201a-2 are also provided on the air guide plate 201a. The elastic member 201a-1 is arranged in a groove 201a-3 opened in the air guide plate 201a. One end of the resistance end 201a-2 is fixedly connected to the elastic member 201a-1, and the other end is in resistance against the inner wall of the air duct 101. When the resistance end 201a-2 is located at the bottom of the air duct 101, the elastic member 201a-1 is in an uncompressed state. When the hydraulic rod 201b contracts to drive the air guide plate 201a to rise, the elastic member 201a-1 contracts so that the resistance end 201a-2 partially contracts into the groove 201a-3, thereby satisfying the flexibility requirement that the air guide plate 201a needs to gradually become shorter when the air guide plate 201a moves in a circular motion.

[0038] Furthermore, the end of the resistance end 201a-2 that resists against the air duct 101 is set to a semi-cylindrical shape. During the rising process of the air guide plate 201a, by cooperating with the reaction force of the elastic member 201a-1, the resistance end 201a-2 can always be in close contact with the inner wall of the air duct 101 and the movement of the air guide plate 201a can be smoother, thereby increasing the airtightness between the built-in adjustment member 201 and the air duct 101 to a certain extent.

[0039] In summary, the present solution can effectively avoid the Bernoulli phenomenon through the built-in adjustment component 201, that is, the wind speed near the air supply port 102 is faster, resulting in a small wind speed pressure at the air outlet 103 near the air supply port 102, resulting in a small amount of air entering the air outlet 103, resulting in the battery cluster near the air supply port 102 having a higher temperature than the battery cluster far away from the air supply port 102.

[0040] Example 2

[0041] Reference Figure 1 to Figure 4 , which is the second embodiment of the utility model, this embodiment provides a heat dissipation cooling air duct with adjustable flow rate. Different from the previous embodiment, this embodiment provides a heat dissipation cooling air duct with adjustable flow rate and also includes an air outlet control component 202 composed of an air outlet pipe 202a and a mesh plate 202b.

[0042] Specifically, the air outlet pipe 202a is fixedly connected to the air outlet 103, and the mesh plate 202b is fixedly connected to the air outlet pipe 202a. The mesh plate is used to control the flow rate of cold air entering the battery rack from the air supply port 103.

[0043] Furthermore, the air outlet pipes 202a are evenly distributed on the side of the air duct 101 close to the battery cluster, such as Figure 4As shown, the aperture ratio of the mesh 202b gradually decreases from one end of the air supply port 103 of the air duct 101 to the other end. Due to the Bernoulli phenomenon, the cold air flow rate at the air supply port 103 close to the air supply port 102 is faster and the pressure is smaller, and the amount of air entering the battery rack from the air supply port 103 is less. Therefore, by setting the aperture ratio of the mesh 202b away from the air supply port 102 to be larger, the air volume passing through the mesh 202b here is greater than that passing through the mesh 202b away from the air supply port 102, thereby ensuring the uniform temperature of the battery rack.

[0044] In summary, this solution can effectively ensure the uniform temperature of the battery rack by providing the air outlet duct 202a and the mesh plate 202b and adjusting the opening rate of the mesh plate 202b.

[0045] Example 3

[0046] Reference Figure 5 to Figure 7 , which is the third embodiment of the utility model, the embodiment provides a control system, the control system includes the heat dissipation cooling air duct with adjustable flow in embodiments 1 and 2, and also includes a monitoring control unit 300 composed of a temperature sensor 301, a hydraulic controller 302 and a control terminal 303.

[0047] Specifically, the temperature sensor 301 is arranged on the battery rack, and the number of the temperature sensors 301 corresponds to the number of the air outlet control components 202, which are used to monitor the real-time temperature of each battery pack. The hydraulic controller 302 is arranged in the air duct 101, which is used to control the hydraulic rod 201b. The control terminal 303 interacts with the temperature sensor 301 and the hydraulic controller 302 through electrical signals.

[0048] Specifically, the temperature sensor 301 monitors the real-time temperature of each battery pack. In particular, after the air source is replaced, when the fixed air outlet control component 202 cannot fully meet the temperature uniformity requirement in the battery rack, the temperature sensor 301 transmits the real-time temperature to the control terminal 303 through an electrical signal. The control terminal 303 compares the temperatures of each temperature sensor 301. If the temperature difference is large and gradually decreases along the air supply port 102 to the other end, the control terminal 303 outputs an electrical signal to the hydraulic controller 302 to control the hydraulic rod 201b to extend, thereby reducing the capacity of one end of the air duct 101 away from the air supply port 102 and reducing the air intake, thereby regulating to meet the temperature uniformity of the battery pack. Otherwise, the hydraulic rod 201b is controlled to extend to increase the air intake, thereby reducing the temperature at the far end.

[0049] In summary, this solution monitors the temperature of each battery pack, especially after changing different wind sources, through the monitoring control unit 300, and compares the temperature of each temperature sensor 301 through the control terminal 303, and controls the hydraulic rod 201b through the hydraulic controller 302 when the temperature difference is large, so as to meet the temperature uniformity of the battery pack.

[0050] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.

[0051] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
