Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and more specifically to an evaporator structure for an energy storage device. Background Technology

[0002] In some existing energy storage devices, such as power batteries, to avoid the problem of reduced lifespan due to heat generation during power supply, these devices are equipped with cooling systems.

[0003] In existing cooling systems, air cooling is generally used, which has limited cooling capacity. Therefore, some equipment incorporates a refrigeration system consisting of components such as evaporators, condensers, compressors, and expansion valves for heat exchange and cooling. However, existing evaporators generally use a single heat exchanger, which has low heat exchange efficiency and is not ideal. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide an evaporator structure for energy storage devices. It uses two evaporators and four heat exchange components for heat exchange, which greatly improves the heat exchange effect.

[0005] The solution of this utility model to the aforementioned technical problem is:

[0006] An evaporator structure for an energy storage device includes a frame, a through groove formed in the middle of the top plate of the frame, two water receiving trays inserted into the left and right parts of the through groove, the water receiving trays being fixed to the top plate of the frame, and an evaporator extending forward and backward being fixed on the top surface of the top plate of the frame above each water receiving tray.

[0007] The evaporator includes two heat exchange main components extending front and rear. The bottom of the two heat exchange main components is fixed to the top surface of the left and right sides of the same bottom bending plate. The front and rear ends of the bottom bending plate are fixed to the front and rear of the top surface of the top plate of the frame. The bottom bending plate is located directly above the corresponding water receiving tray.

[0008] The two heat exchange components of each evaporator are V-shaped with their upper parts far apart and their lower parts close together. A transverse connecting beam is fixed between the top connecting beam plates of the corresponding two heat exchange components.

[0009] The top of the vertical support columns on the four side walls of the frame extends upward beyond the top surface of the frame and fixes the top cover plate. The top cover plate has multiple through holes formed directly above each evaporator, and a cooling fan is fixed to the top surface of the top cover plate at the through holes.

[0010] The heat exchange main component consists of multiple S-shaped coiled heat exchange tubes and multiple heat dissipation fins clamped on the heat exchange tubes. Each evaporator has an end baffle fixed at the front and rear ends of the space between the two heat exchange main components. The end baffle covers the front or rear end of the space between the two heat exchange main components.

[0011] The lower center of the rear wall panel of the water receiving tray is formed with a drainage hole, which is connected to a drain head on the rear wall surface of the rear wall panel of the water receiving tray.

[0012] The bottom plate of the water receiving tray extends obliquely downward from front to back, and the left and right side walls of the water receiving tray are oblique wall panels with their upper ends far apart and their lower ends close together.

[0013] The outstanding effect of this utility model is:

[0014] Compared with existing technologies, it uses two evaporators and four heat exchange components for heat exchange, which greatly improves the heat exchange effect.

[0015] Furthermore, the two heat exchange bodies of each evaporator are V-shaped, which increases the contact area with air, thereby increasing the heat exchange effect and efficiency. Attached Figure Description

[0022] For example, see below. Figures 1 to 6 As shown, an evaporator structure for an energy storage device includes a frame 10. A through groove 11 is formed in the middle of the top plate of the frame 10. Two water receiving trays 20 are inserted into the left and right parts of the through groove 11. The water receiving trays 20 are fixed to the top plate of the frame 10. An evaporator 30 extending from front to back is fixed on the top surface of the top plate of the frame 10 above each water receiving tray 20.

[0023] The evaporator 30 includes two heat exchange main components 31 extending front and rear. The bottom of the two heat exchange main components 31 is fixed to the top surface of the left and right sides of the same bottom bending plate 32. The front end and rear end of the bottom bending plate 32 are fixed to the front and rear parts of the top surface of the top plate of the frame 10. The bottom bending plate 32 is located directly above the corresponding water receiving tray 20.

[0024] The two heat exchange components 31 of each evaporator 30 are V-shaped with their upper parts far apart and their lower parts close together. A transverse connecting beam 35 is fixed between the top connecting beam plates of the corresponding two heat exchange components 31.

[0025] The top of the vertical support columns on the four side walls of the frame 10 extends upward beyond the top surface of the frame 10 and fixes the top cover plate 12. The top cover plate 12 is formed with multiple through holes directly above each evaporator 30, and a cooling fan 13 is fixed on the top surface of the top cover plate 12 at the through holes.

[0026] In this embodiment, two evaporators 30 are used. Each evaporator 30 includes two heat exchange components 31, which are V-shaped, thereby increasing the contact area with air and improving the heat exchange effect and efficiency.

[0027] Furthermore, the two evaporators 30 have four heat exchange components 31, which greatly increases their heat exchange area and significantly improves the cooling effect around the installation location in this embodiment. In addition, the cross-sections of the two evaporators 30 are V-shaped, which reduces the space occupied in the horizontal direction.

[0028] Furthermore, the heat exchange main component 31 is composed of multiple S-shaped coiled heat exchange tubes and multiple heat dissipation fins clamped on the heat exchange tubes. Each evaporator 30 has an end baffle 33 fixed at the front end and rear end of the space between the two heat exchange main components 31. The end baffle 33 covers the front end or rear end of the space between the two heat exchange main components 31.

[0029] The top cover plate 12 is composed of two front-to-back extending sub-cover plates 121. The top surfaces of the adjacent sides of the two sub-cover plates 121 are fixed with the same front-to-back extending connecting beam 122. Each sub-cover plate 121 has multiple through holes formed on it. A cooling fan 13 is fixed on the top surface of the sub-cover plate at the through holes.

[0030] Mesh panels 1 are fixed between the top cover plate 12, the top plate of the frame 10, and the vertical support column between them. All mesh panels 1 cover the four sides between the top cover plate 12 and the top plate of the frame 10.

[0031] Furthermore, the lower middle part of the rear wall plate of the water receiving tray 20 is formed with a drainage through hole, which communicates with a drainage head connected to the rear wall surface of the rear wall plate of the water receiving tray 20.

[0032] The bottom plate of the water receiving tray 20 extends obliquely downward from front to back, and the left and right side walls of the water receiving tray 20 are oblique wall panels with their upper ends far apart and their lower ends close together.

[0033] This structure allows the condensate in the evaporator 20 to drip onto the drip tray 20, where it flows backward along the bottom plate and collects at the rear, facilitating drainage from the drain head, reducing accumulation, and improving drainage performance.

[0034] Furthermore, multiple horizontal connecting plates 21 are fixed at the top between the two water receiving trays 20. This improves the connection effect between the two water receiving trays 20.

[0035] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model, and the patent protection scope of the present utility model should be defined by the claims.
