Description

Technical Field

[0001] This utility model relates to the field of cold storage equipment technology, specifically to an inlet distributor suitable for phase change cold storage plates. Background Technology

[0002] With the government's implementation of electricity policies encouraging peak-shaving and valley-filling to fully utilize electricity resources, air conditioning with thermal storage has become increasingly popular. Currently, water-based thermal storage and ice-based thermal storage systems have been developed on the market. Both utilize the peak-valley electricity price difference to store cooling / heat during off-peak hours and use the stored cooling / heat to provide cooling / heating for air conditioning during peak daytime hours. When air conditioning usage time coincides with non-air conditioning usage time and the grid's peak and off-peak hours, the electricity consumption for air conditioning during peak hours can be shifted to off-peak hours.

[0004] Reference 1 describes a phase change energy storage water tank, the structure of which includes a water tank body, a phase change cold storage layer disposed within the water tank body, and equalization water pipes for water inlet and outlet respectively disposed on opposite sides of the water tank body along its length. The equalization water pipes include a main pipe and branch pipes, with the branch pipes disposed inside the water tank body. Each branch pipe includes at least one diversion pipe, and a plurality of equalization holes are evenly formed on the side wall of the diversion pipe facing the inner side wall. A flow-dispersing perforated plate is disposed between the equalization water pipes and the phase change cold storage layer, and the flow-dispersing perforated plate is machined with evenly distributed through holes. A plurality of flow-dispersing baffles are disposed on the periphery of the water tank body along its length and between the water tank body and the phase change cold storage layer, spaced apart along the length of the water tank body. This phase change energy storage water tank not only allows water or refrigerant to enter the water tank evenly, but also further allows the water or refrigerant to fully contact, mix, and exchange heat with the phase change material within the water tank, thereby improving the cold storage or cooling effect of the phase change cold storage water tank.

[0005] Reference 2: Chinese patent document with publication number CN 115752056 A

[0006] Reference 2 describes a high-efficiency and stable phase change cold storage device using thin-plate encapsulation. The device includes a tank and multiple phase change cold storage plates disposed inside the tank. The tank contains a support frame and support beams. The phase change cold storage plates are supported by the support beams and placed on the support frame. The multiple phase change cold storage plates are placed horizontally, with adjacent plates not in contact. Each phase change cold storage plate has slots. The phase change cold storage plates are staggered within the tank, and the slots form an "S"-shaped flow channel. During cold storage, cold water is introduced from the bottom of the tank to exchange heat with the phase change cold storage plates. This phase change cold storage device targets hydrated salt phase change cold storage systems. By encapsulating the hydrated salt phase change material with thin plates, it effectively suppresses the phase separation characteristics of the hydrated salt phase change material, ensuring efficient heat exchange and circulation stability of the phase change cold storage device, thereby promoting the development of phase change cold storage air conditioning.

[0007] However, existing phase change cold storage devices suffer from uneven cold storage / release at different locations on the cold storage plates. Plates closer to the refrigerant inlet are fully charged in a shorter time, while those farther away require a longer time to fully charge, ultimately leading to a longer overall charging time for the cold storage device. Based on this, the applicant designed and developed a new cold storage device. However, how to ensure a more uniform flow of fluid through the cold storage plate modules to achieve higher utilization and phase change efficiency remains a problem to be solved.

[0038] To better understand this utility model, the following embodiments further illustrate the content of this utility model, but the content of this utility model is not limited to the following embodiments.

[0039] like Figure 1-4 As shown: An inlet distributor suitable for phase change cold storage plates includes a plate body 1 and a support member 2, with water passage holes 3 evenly opened on the plate body 1.

[0040] The support member 2 can take the following two forms:

[0041] Form 1: The support member 2 consists of multiple support bars 21 vertically arranged on one side of the plate 1. The multiple support bars 21 are parallel to each other, and the support bars 21 are provided with guide holes 22.

[0042] Specifically, the position of the support bar 21 on the plate 1 does not interfere with the water passage hole 3, meaning that the position of the support bar 21 does not block any water passage hole 3. Multiple guide holes 22 are evenly arranged along the length of the support bar 21. The guide holes 22 are triangular holes, and the apex of the triangular holes faces away from the plate 1.

[0043] Form 2: The support member 2 includes multiple support columns 23 vertically arranged on one side of the plate 1, and the tops of the multiple support columns 23 located in the same column or row are connected together by limiting rods 24.

[0044] The plate 1 and the support component 2 can be made of metal, such as stainless steel, nickel alloy, or aluminum alloy. Alternatively, they can be made of non-metallic materials, such as fluoroplastics, boron carbide ceramics, or borosilicate glass.

[0045] like Figure 5As shown, a phase change cold storage device includes a housing 4. The interior of the housing 4 is divided into upper and lower layers by a horizontal partition. Each layer is divided into three flow channels by a vertical partition 5. The housing 4 has an inlet and an outlet at both ends corresponding to each flow channel. The inlets and outlets of two adjacent flow channels are arranged in opposite directions. The three flow channels on the same layer are connected in series through the inlets and outlets. The total outlet of the lower layer is connected to the total inlet of the upper layer.

[0046] The box 4 has a main water inlet at the head end of the lower cavity flow channel and a main water outlet at the tail end of the upper cavity flow channel. The flow channels of the two cavities are connected in series to form a refrigerant flow channel, and a cold storage module 6 is installed in the flow channel.

[0047] The cold storage module 6 includes multiple sets of cold storage components arranged along the flow direction of the refrigerant. Each set of cold storage components includes multiple cold storage plates arranged side by side, with gaps between adjacent cold storage plates for the refrigerant to flow through.

[0048] Each flow channel is equipped with an inlet distributor at its inlet end. The inlet distributor makes the distribution and flow of the refrigerant more uniform. The inlet distributor makes the fluid evenly distributed on the heat exchange surface, increases the contact area between the fluid and the heat exchange surface, allows for more complete energy transfer, reduces local dead zones, and improves the overall heat transfer coefficient, thereby improving the heat transfer efficiency.

[0049] The specific embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this utility model.
