[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Example

[0028] like Figure 1 , 2 As shown, this embodiment provides an adjustable detachable flat plate phase change energy storage device, including a shell 1 with an opening, a cover 6 and an energy storage plate 7, wherein the energy storage plate 7 is provided in plurality, and the plurality of energy storage plates 7 are laid layer by layer in the shell 1, and an extension frame is fixed around the outer periphery of the opening of the shell 1, and the cover 6 is detachably connected to the extension frame to close the opening, and the extension frame is flush with the opening edge of the shell 1. The plurality of energy storage plates 7 are parallel to each other and are arranged parallel to the bottom of the shell 1.

[0029] A limiter 9 is provided in the shell 1 to separate the energy storage plate 7. The limiter 9 includes a mounting component mounted on the shell 1 and a limiter component for supporting the energy storage plate. The limiter component is rotatably connected to the mounting component via a pin shaft. The limiter component can rotate around the pin shaft. When the limiter component is placed in the same straight line as the mounting component, it is used to support the energy storage plate 7 thereon. When the limiter component is placed perpendicular to the mounting component, there is space between the limiter component and the energy storage plate 7 on the lower layer, so that the energy storage plate 7 is taken out of the shell, which is convenient for taking the energy storage plate 7 on the lower layer. Example

[0030] like Figure 1-7As shown, this embodiment provides a technical solution based on the embodiment 1, which is different from the embodiment 1 in that a groove 5 for placing a sealing ring is provided near the inner ring of the extension frame, a plurality of housing threaded holes 4 are distributed near the outer ring of the extension frame, and the cover 6 is provided with cover threaded holes corresponding to the housing threaded holes 4 one by one, and the cover 6 is detachably connected to the extension frame through screws, the housing threaded holes 4 and the cover threaded holes. The housing threaded holes 4 are evenly distributed on the extension frame, and a sealing ring is placed in the groove 5 to achieve the effect of sealing the housing 1 with the cover 6.

[0031] The inner wall of the housing 1 is provided with a plurality of brackets 8 for mounting the stopper 9. The bracket 8 comprises two long strips with grooves, which are welded to the inner wall of the housing 1 at intervals, and the intervals are equal to the width of the mounting component on the stopper 9. The stopper 9 is fixed in the groove of the long strip through the threaded holes and screws on the mounting component, and the limiting component of the stopper 9 is in the shape of a flat cam and can be rotated on the mounting component, so as to facilitate the support and taking of the energy storage plate.

[0032] The bracket 8 is fixed on the inner wall perpendicular to the bottom of the shell 1. The bracket 8 is evenly provided with multiple limiters 9 from top to bottom. The limiter 9 at each height limits an energy storage plate. The upper and lower energy storage plates 7 are separated by the limiters 9 and do not contact each other.

[0033] The bracket 8 is arranged on two opposite inner wall surfaces of the shell 1, three groups of the brackets 8 are arranged on one inner wall surface, and six limiters 9 are arranged on one group of brackets. The limiters 9 arranged at the same height of the brackets 8 form a partition for placing the energy storage plate 7, dividing the internal space of the shell 1 into six partitions, each partition includes six limiters 9, and every three limiters 9 are arranged on one inner wall surface to ensure the stable use of the energy storage plate 7.

[0034] The cover 6 is provided with a handle on its outward side to facilitate carrying the entire energy storage device.

[0035] The cover is provided with a 1mm wide boss on one side facing the inside of the housing 1, and the boss is used to position the cover 6 on the housing 1. After the cover 6 is placed at the opening of the housing 1, the boss is attached to the inner wall of the housing 1, and the cover threaded holes on the cover correspond to the housing threaded holes 4 one by one, which is convenient for installing screws and avoids the phenomenon that the remaining threads are difficult to fix after some threads are positioned. The boss, the housing 1, and the sealing ring are distributed from the inside to the outside to ensure the sealing of the inside of the housing 1.

[0036] like Figure 6 , 7As shown, the energy storage plate 7 is evenly provided with short ribs at an angle of 45° to its edge line on both sides, and the short ribs are in a convex state. The angle of the short ribs on both sides of the energy storage plate 7 is 90°, and the short ribs between each surface are parallel and evenly distributed. The arrangement of the short ribs can destroy the original laminar flow state of the fluid between the plates, so that a vortex turbulence is formed between the short ribs, and the heat exchange effect of the fluid is enhanced. The arrangement of the short ribs can increase the contact area between the energy storage plate and the heat exchange fluid, and improve the heat exchange effect between the plate and the fluid.

[0037] A water inlet 2 and a water outlet 3 are respectively provided on two opposite outer side walls of the shell 1 , and the heat exchange fluid enters from the water inlet 2 and is discharged from the water outlet 3 .

[0038] The filling material in the energy storage plate 7 is sodium acetate trihydrate, paraffin or a composite working fluid thereof for heat storage, or caprylic acid, lauric acid or a composite working fluid thereof for cold storage.

[0039] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
