Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water distributors, and specifically relates to a water distributor for an air-conditioning cold storage system. Background Technique
[0002] The water-cooled air-conditioning technology refers to that during the low-power consumption period at night when the power load is very low, a refrigeration machine is used for refrigeration, and the sensible heat characteristic of water is utilized to store the cold quantity in a certain way; during the high-power consumption peak period, the stored cold quantity is released to meet the needs of building air-conditioning or production processes. With the strong promotion of peak-valley electricity prices by the state, the water-cooled air-conditioning technology has been paid more and more attention. The water storage tanks currently used in water-cooled air-conditioning systems are mainly divided into temperature-stratified types, mixed-tank types and maze types. Among these, the temperature-stratified water storage tank is the most widely used. The temperature-stratified water storage tank realizes stratification through the density difference based on the different densities of cold water and warm water, preventing the mixing of cold and warm water and reducing heat loss. According to the characteristic that the density of water decreases with the increase of temperature, cold water is stored at the lower part of the water storage tank, and warm water is stored at the upper part. Forming a stable thermocline between cold and warm water is the key to reducing heat loss.
[0003] In order to form a thermocline in the water storage tank and prevent the mixing of cold and warm water caused by the impact of cold and warm water entering and leaving the water storage tank on the water in the tank, water distributors need to be arranged at the upper and lower parts of the water storage tank; the water distributor is an important component in the air-conditioning cold storage system, mainly responsible for evenly distributing cold water into the cold storage tank or evenly releasing the cold water in the cold storage tank, and should make the cold and warm water enter and leave the water storage tank as smoothly, slowly, evenly and without disturbance as possible. <(
[0004] To solve the above problems, we propose a water distributor for an air-conditioning cold storage system to solve the above problems. Content of the Utility Model
[0005] To solve the problems in the background technique, the utility model provides a water distributor for an air-conditioning cold storage system.
[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0007] A water distributor for an air-conditioning cold storage system includes a throttling plate, and a fluid guiding component is arranged on the upper end surface of the throttling plate. The fluid guiding component is used for evenly dividing the upper end area of the throttling plate, and an internal thread short pipe is connected to the center of the upper end of the fluid guiding component;
[0008] The top view structure of the fluid guiding component is in the shape of a "rice" character, and the fluid guiding component includes a first dividing plate, a second dividing plate and a third dividing plate.
[0009] Preferably, the first partition plate is vertically installed on the upper surface of the cutoff plate, and the two ends of the first partition plate are respectively installed at diagonal positions on the cutoff plate.
[0010] Preferably, there are two sets of the second partition plate, located at the middle of both ends of the first partition plate, and vertically installed on the upper surface of the interceptor plate.
[0011] Preferably, there are four sets of the third partition plate, which are installed in a cross shape on the upper surface of the interceptor plate.
[0012] Preferably, the flow cut-off plate, the fluid guiding assembly, and the inner threaded short tube are all connected and fixed by intermittent welding.
[0013] Preferably, the first partition plate, the second partition plate, and the third partition plate are all configured as trapezoidal structures.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This utility model water distributor has a simple structure, low manufacturing cost, easy assembly and disassembly, and high structural strength. It separates and guides the cold storage water through the internal thread short tube and fluid guiding component, so that the cold storage water can flow evenly into the cold storage water tank and will not form a large fluid vortex around the water distributor. This ensures the relative stability of the original cold storage water layer in the cold storage water tank, thereby effectively avoiding cross-convection between the newly added cold storage water and the original cold storage water.

[0022] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:
[0023] Example: Refer to Figure 1 - Figure 5 As shown in Figure 5 , a water distributor of an air-conditioning cold storage system in this embodiment includes a throttle plate 1. A fluid guiding component 2 is provided on the upper surface of the throttle plate 1. The fluid guiding component 2 is used to evenly divide the upper area of the throttle plate 1. The inner wire short pipe 3 is connected to the center of the upper end of the fluid guiding component 2; the top view structure of the fluid guiding component 2 is in the shape of a "rice" character, so as to evenly divide the diversion area of the throttle plate 1, resulting in 8 diversion directions.
[0024] In some examples, the fluid guiding component 2 includes a first partition plate 21, a second partition plate 22 and a third partition plate 23.
[0025] In some examples, the first partition plate 21 is vertically installed on the upper surface of the throttle plate 1, and both ends of the first partition plate 21 are installed at the diagonal positions of the throttle plate 1.
[0026] In some examples, there are two groups of the second partition plates 22, which are respectively located in the middle of both ends of the first partition plate 21 and are vertically installed on the upper surface of the throttle plate 1.
[0027] In some examples, there are four groups of the third partition plates 23, which are installed on the upper surface of the throttle plate 1 in a "cross" shape.
[0028] In some examples, the throttle plate 1, the fluid guiding component 2 and the inner wire short pipe 3 are all connected and fixed by intermittent welding.
[0029] In some examples, the outer shapes of the first partition plate 21, the second partition plate 22 and the third partition plate 23 are all set as trapezoidal structures.
[0030] In some examples, the material of this water distributor is made of stainless steel, which prolongs the service life.
[0031] The working principle of this utility model is:
[0032] During use, the chilled water for storage flows out from the end branch pipe through the inner wire short pipe 3. At this time, the fluid guiding component 2 can divide the chilled water for storage, so that the chilled water for storage flows in eight directions along the fluid guiding component 2, so that the chilled water for storage can flow evenly into the chilled water storage tank (container), and no large fluid vortices will be formed around the water distributor, ensuring the relative stability of the original chilled water in the chilled water storage tank (container), and avoiding the convection of the newly added chilled water for storage and the original chilled water for storage.
[0033] This utility model adjusts the longitudinal position of the water distributor by using the inner threaded short tube 3, making it very suitable for use in cold water storage tanks (containers) with low inner surface flatness, ensuring that the baffle plate 1 and the inner surface are in close contact; in addition, this utility model is made of stainless steel, which extends its service life and is easy to process and manufacture, and the various parts can be spot welded together, avoiding stress deformation. It is more suitable for use in cold storage systems with small volume and has a relatively low cost.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
