Description

Technical Field

[0001] The utility model belongs to the technical field of battery management, and in particular relates to a battery compartment. Background Art

[0002] The battery compartment is a structure or space used to store and protect batteries. It is widely used in various devices and vehicles. To ensure that the batteries operate at a suitable ambient temperature, most existing battery compartments are equipped with air conditioning and cooling systems. Currently, air conditioning systems for battery compartment cooling are mainly divided into three modes:

[0003] Mode 1: External industrial air conditioner direct blowing mode;

[0004] Mode 2: Based on external industrial air conditioning and top duct direct downward blowing mode;

[0005] Mode 3: Direct airflow to the battery pack using external industrial air conditioning and branch air ducts;

[0006] The first two modes can only cool down a large area and cannot effectively control the temperature difference between each battery pack. Although the last mode has a separate air outlet for each battery pack, the air volume at the air outlet is small due to the low air speed of the air conditioner, and can only cover the battery pack close to the air outlet.

[0007] Based on the above analysis, this application designs a battery compartment with a new structure. Utility Model Content

[0008] The purpose of the present utility model is to provide a battery cabin, in which a plurality of battery racks in a box structure are added to the interior of the battery cabin, and a plurality of air outlets are opened on the battery racks in the box structure, which significantly increases the air volume and wind speed, so that the cold air flow can better cover the battery packs at various positions in the cabin, effectively improve the heat dissipation efficiency, and solve the shortcomings existing in the above-mentioned background technology.

[0009] In order to solve the above problems, the present application provides a battery cabin, including a cabin body, in which a plurality of groups of battery rack plates are arranged side by side along the length direction of the cabin body, and two adjacent battery rack plates constitute a battery rack for supporting a battery pack, and each of the battery rack plates, either located at an even position or at an odd position, has a hollow box structure, and the hollow cavity of the battery rack plate of the box structure is connected to the industrial air-conditioning system located outside the cabin body. At the same time, an air outlet is opened on the battery rack plate of the box structure, and the air outlet is connected to the hollow cavity.

[0010] As a preferred solution of the present application, it includes a return air duct, which is installed near the top of the cabin. The return air duct is connected to the negative pressure system located outside the cabin, and multiple groups of air vents are provided on the return air duct. The return air duct and the battery rack plate of the box structure constitute an air flow channel.

[0011] As a preferred solution of the present application, the return air duct includes multiple groups arranged in parallel, and the multiple groups of return air ducts are independent of each other.

[0012] As a preferred solution of the present application, when the battery rack plate located at an even position or an odd position is a hollow box structure, the battery rack plate at other positions includes a column and a support plate, the column is vertically fixed in the cabin, and the support plate is arranged on at least one side of the column for supporting the battery pack.

[0013] As a preferred solution of the present application, when the battery rack plate is a box structure, the battery rack plate includes a sealing plate, a support plate and at least two groups of columns. The two groups of columns are opposite to each other and are vertically fixed in the cabin with a certain gap. The support plate includes multiple groups, which are equidistantly arranged on the contact sides of the two groups of columns and the battery pack. The sealing plate is used to seal the gap between the two groups of columns and the opening between the columns and the support plate to form a closed box structure.

[0014] As a preferred solution of the present application, the top of the battery rack of the box structure is provided with an air inlet for receiving the cold air flow from the industrial air-conditioning system.

[0024] The present invention will be further described in detail below in conjunction with specific implementation methods and with reference to the accompanying drawings. It should be emphasized that the following description is merely illustrative and is not intended to limit the scope of the present invention and its applications.

[0025] like Figure 1As shown, it is a schematic diagram of the overall structure of a battery cabin provided in this embodiment, the battery cabin includes a cabin body 1, and a plurality of battery rack plates 2 are arranged side by side along the length direction of the cabin body 1, and two adjacent battery rack plates 2 constitute a battery rack for supporting the battery pack 10; each battery rack plate 2 or the battery rack plates 2 located at an even position or an odd position has a hollow box structure, and the hollow cavity of the battery rack plate 2 of the box structure is connected to the industrial air-conditioning system located outside the cabin body 1, and at the same time, an air outlet 7 is provided on the battery rack plate 2 of the box structure, and the air outlet 7 is connected to the hollow cavity. In this embodiment, the battery rack plate 2 of the box structure is connected to the industrial air-conditioning system through a hose or a docking port. In this embodiment, an air inlet 6 for receiving a cold air flow from the industrial air-conditioning system is preferably provided on the top of the battery rack plate 2 of the box structure. It can be understood that the air inlet 6 should correspond to the air outlet 7 of the industrial air-conditioning system, so as to maximize the utilization of the cold air flow.

[0026] During use, the cold air flow provided by the industrial air-conditioning system enters the hollow cavity of the corresponding battery rack plate 2 through the air inlet 6 to realize the convergence of the cold air flow, and the converged cold air flow is then blown out through the air outlet 7 at a certain pressure and flow rate to achieve the purpose of cooling the battery packs 10 at various positions; it can be seen that this solution realizes the regulation of the air volume and wind speed of the cold air flow from the industrial air-conditioning system by adding multiple battery rack plates 2 with a box structure inside the battery cabin, and opening air outlets 7 on the battery rack plates 2 with a box structure, thereby significantly increasing the air volume and wind speed of the cold air flow, so that the cold air flow can better cover the battery packs 10 at various positions in the cabin 1, effectively improving the heat dissipation efficiency, and solving the shortcomings of the above-mentioned background technology.

[0027] The number of battery racks 2 in the cabin 1 designed as box structures can be designed according to actual cooling requirements. In order to reduce design costs and meet the required cooling requirements, in this embodiment, it is preferred that only the battery racks 2 located at even or odd positions are hollow box structures. The battery racks 2 at even or odd positions and the battery racks at adjacent positions form a battery rack for supporting the battery pack 10, and the battery racks 2 with non-box structures will be located between the two battery racks 2 with box structures, such as Figure 1 or Figure 4 As shown ( Figure 4 The middle arrow indicates the flow direction of the cold air through the air outlet 7).

[0028] The air outlet 7 is arranged on the contact side of the battery rack plate 2 and the battery pack 10 of the box structure, and the setting position of the air outlet 7 on the battery rack plate 2 corresponds to the contact position of the battery pack 10 and the battery rack plate 2, that is, an air outlet 7 is respectively provided at each position where the battery plate rack contacts the battery pack 10, thereby improving the uniformity of the cold air flow flowing through each battery pack 10 at each position and further improving the cooling efficiency.

[0029] The battery panel rack of the box structure includes a sealing plate 5, a support plate 4 and at least two groups of columns 3, such as Figure 2 As shown, each group of columns 3 includes multiple columns arranged longitudinally, and the two groups of columns 3 are opposite to each other and vertically fixed in the cabin 1 with a certain gap. It can be understood that the size of the gap should meet the cooling requirements. In this embodiment, it is preferably between 4-8 cm; the support plates 4 include multiple groups, which are equidistantly arranged on the contact side of the two groups of columns 3 and the battery pack 10, that is, the outside. The support plates 4 are preferably L-shaped angle steels, which are welded to the outside of the columns 3; the sealing plates 5 are used to seal the gaps between the two groups of columns 3 and the openings between the columns 3 and the support plates 4 to form a closed box structure. In this embodiment, the sealing plates 5 are preferably steel plates.

[0030] The battery rack 2 at other locations outside the box structure includes a column 3 and a support plate 4. The column 3 is vertically fixed in the cabin 1, and the support plate 4 is arranged on at least one side of the column 3 for supporting the battery pack 10. Figure 2 As shown, the battery rack plate 2 of this structure is simple and lightweight, and has a hollow structure, which facilitates the passage of cold air.

[0031] As a preferred embodiment of the present application, the cabin 1 further comprises a return air duct 8, such as Figure 3 As shown, the return air duct 8 is installed near the top of the cabin 1 through a bracket 9, specifically above each battery rack plate 2 in the cabin 1, and the return air duct 8 is connected to the negative pressure system located outside the cabin 1, and a plurality of groups of air vents 11 are provided on the return air duct 8. The return air duct 8 and the battery rack plate 2 of the box structure constitute an air flow channel; it can be understood that in this embodiment, the air vents 11 should be micro holes, and the specific aperture can be set according to actual needs, which is not limited in detail in this embodiment.

[0032] The return air ducts 8 include multiple groups arranged in parallel, and the multiple groups of return air ducts 8 are independent of each other.

[0033] like Figure 3-4 As shown, the direction of air flow in the cabin 1 after the return air duct 8 is installed provided in this embodiment (the flow direction is indicated by an arrow). In the figure, the battery rack plate 2 of the box structure receives the cold air flow from the industrial air conditioner through the air inlet, and then enters the cabin 1 through the air outlet 7 thereon and cools the battery packs 10 at various positions. The air flow after completing the heat exchange rises to the top of the cabin 1. At this time, the negative pressure system is started to draw the hot air flow out of the cabin 1 through the vents 11 on the return air duct 8. It can be seen that the air flow flow channel formed by the return air duct 8 and the battery rack plate 2 of the box structure in this embodiment accelerates the speed of the air flow in the cabin 1, further improves the heat exchange efficiency, and achieves effective and rapid cooling.

[0034] The above is only an embodiment of the present invention. The commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several improvements can be made without departing from the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of the claims. The specific implementation methods and other records in the specification can be used to interpret the content of the claims.
