Description

Technical Field

[0001] This utility model relates to the field of heat exchanger energy storage technology, specifically to a heat exchanger energy storage device. Background Technology

[0002] A heat exchanger energy storage device is a system that combines a heat exchanger (usually used for heat transfer) with an energy storage device (used for storing thermal energy). Hot water storage tanks and heating water tanks are also known as hot water storage tanks. They belong to the category of heat exchange equipment and mainly include two functional units: heating water tanks and hot water storage tanks.

[0003] The original energy storage device adopted a split design: the heating water tank and the hot water storage tank are independent units connected by external pipes. In small factory scenarios, the dual-unit layout occupies too much space, exacerbating the space shortage problem. When the energy storage device is used, the insulation layer of the original device has limited effectiveness, resulting in significant heat loss during the heat storage process. This leads to the need for frequent reheating to maintain the water temperature, resulting in low energy efficiency.

[0004] The purpose of this invention is to provide an energy storage device for heat exchange units to solve the problems mentioned in the background art. Utility Model Content

When using the energy storage device, the insulation layer of the original device has limited effectiveness, resulting in significant heat loss during the heat storage process, leading to the need for frequent reheating to maintain the water temperature and low energy efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figure 1-4 The heat exchanger unit energy storage device includes;

[0028] A bracket 1 is provided, with an energy storage box 2 fixedly installed on the upper end of the bracket 1. An insulation shell 3 is fixedly installed on the outer side of the energy storage box 2. An inner layer 4 is fixedly installed on the inner wall of the energy storage box 2, and a sandwich layer 5 is fixedly installed inside the inner layer 4. A heating cavity 6 is fixedly opened at the lower end of the energy storage box 2, and a water inlet pipe 7 is fixedly installed at the rear end of the heating cavity 6. A drain pipe 8 is fixedly installed at the front end of the heating cavity 6. A heating coil 9 is fixedly installed on the inner wall of the energy storage box 2.

[0029] Heating coil 2 10 is fixedly installed inside the heating cavity 6. A conveying end 11 is fixedly installed behind the upper end of heating coil 1 9. An output end 12 is fixedly installed in front of the upper end of heating coil 1 9. A drain pipe 13 is fixedly installed above the output end 12. A connecting pipe 14 is fixedly installed on the upper end of the conveying end 11, and a valve 15 is fixedly installed on the upper end of the connecting pipe 14.

[0030] The energy storage box 2 is divided into a heating chamber 6 and a heat storage chamber 17 by a partition 16. The water inlet pipe 7 and the drain pipe 8 are symmetrically installed on the front and back sides of the heating chamber 6 with the lower end of the heating chamber 6 as the center reference. The top pipe of the water inlet pipe 7 is fixedly connected to the heat storage chamber 17.

[0031] Heating coil 9 and heating coil 10 have the same structure and are connected by a pipe.

[0032] The conveying end 11, the inlet pipe 7 and the connecting pipe 14 are fixedly installed on the same straight line. The output end 12, the sewage pipe 8 and the drain pipe 13 are fixedly installed on the same straight line. The drain pipe 13 and the connecting pipe 14 are symmetrically installed on the front and back sides of the heating cavity 6 with the upper end of the heating cavity 6 as the center reference.

[0033] In this embodiment, the energy storage box 2 is installed and fixed by the bracket 1. An insulating shell 3 is added to the outside of the energy storage box 2. The insulating shell 3 is made of mineral wool and rock wool. Its main function is to reduce the heat loss of the hot water inside the energy storage box 2 to the external environment. An inner layer 4 is set inside the insulating shell 3. The main body of the inner layer 4 is a polyurethane insulation layer, and there is a sandwich layer 5 inside it. The sandwich layer 5 is filled with silica aerogel. The inner layer 4 and the sandwich layer 5 work together to form a highly efficient heat insulation barrier, which significantly enhances the overall heat insulation performance of the energy storage box 2. The heating cavity 6 is installed at the lower end inside the energy storage box 2. A double heating coil is installed inside the heating cavity 6. Heating coil 19 directly acts on the inner wall of the heating cavity 6 to continuously heat it, while heating coil 20 is immersed in the water in the heating cavity 6 to directly heat the water. This design of simultaneous heating inside and outside (heating coil 19 heats the cavity wall, and heating coil 20 directly heats the water) significantly improves the heat transfer efficiency, thereby accelerating the water heating process.

[0034] Example 2:

[0035] Please see Figure 5 This embodiment provides a technical solution based on Embodiment 1:

[0036] A partition 16 is fixedly installed on the upper end of the heating chamber 6. A heat storage chamber 17 is fixedly opened on the upper end of the energy storage box 2. A cold water pipe 18 is fixedly installed behind the upper end of the heat storage chamber 17. A drain pipe 19 is fixedly installed in front of the upper end of the heat storage chamber 17. A heat absorption plate 20 is fixedly installed on the inner wall of the heat storage chamber 17. A first sensor 21 is fixed above the heat absorption plate 20, and a second sensor 22 is fixed below the heat absorption plate 20.

[0037] The cold water pipe 18 and the drain pipe 19 are symmetrically installed on the front and rear sides of the heat storage cavity 17 with the heat storage cavity 17 as the center reference. The first sensor 21 and the second sensor 22 have the same structure.

[0038] In this embodiment, the energy storage tank 2 is divided into two independent chambers by a partition 16: a heating chamber 6 located below and a heat storage chamber 17 located above. The two chambers are connected by a connecting pipe 14. The water in the heating chamber 6 is efficiently heated by a double-layer heating coil (heating coil 9 acts on the chamber wall, and heating coil 10 directly heats the water) installed inside. After heating, the hot water is transported to the upper heat storage chamber 17 through the connecting pipe 14 for heat preservation and storage. A heat absorption plate 20 is installed on the inner wall of the heat storage chamber 17. The main function of the heat absorption plate 20 is to absorb some heat during the initial injection of hot water or when the temperature fluctuates, and to slowly release it when the water temperature drops, which helps to... To stabilize the water temperature inside the thermal storage chamber 17, reduce temperature fluctuations, and improve insulation performance, two high-temperature and high-pressure liquid level sensors are installed inside the thermal storage chamber 17 to accurately monitor its operating status. The first sensor 21 is installed at the upper end inside the thermal storage chamber 17 to monitor the high liquid level, and the second sensor 22 is installed at the lower end inside the thermal storage chamber 17 to monitor the low liquid level. The sensor model is FS-IR2016D-H. These sensors monitor the water level and bottom status inside the thermal storage chamber 17 in real time. The monitoring data is used to control the opening and closing of the water supply pipes. For example, when the liquid level is low, the cold water pipe 18 is opened to replenish water, and when the liquid level is high, the cold water pipe 18 and the connecting pipe 14 are closed.

[0039] The working principle of this utility model is as follows: The energy storage box 2 is fixedly installed by the bracket 1. The insulation structure adopts a double-layer design. The outer layer is an insulation shell 3 composed of mineral wool and rock wool to reduce environmental heat loss. The inner layer is a polyurethane inner layer 4 integrated with a silica aerogel interlayer 5 to form a high-efficiency composite heat insulation barrier. When the solenoid valve is activated, cold water is injected into the heating chamber 6 through the water inlet pipe 7. The heating chamber 6 is equipped with a double-layer heating ring. Heating ring 1 9: circumferentially wraps the inner wall of the chamber, directly heating the metal wall surface. Heating ring 2 10: is immersed in water, directly heating the water. The heat source is provided by an external heat exchange unit through the conveying end 11 to realize energy input. After heating, the heat... As the water density decreases, it rises and accumulates at the top of the heating chamber 6. The valve 15 of the connecting pipe 14 is opened, and hot water is transported to the heat storage chamber 17 through the connecting pipe 14. The two chambers are physically separated by the partition 16 to ensure that the hot and cold water are separated. When the hot water enters the heat storage chamber 17, the high temperature and high pressure liquid level sensor at the bottom of the second sensor 22 monitors the water level in real time and triggers the water mixing program. Cold water is injected into the cold water pipe 18 according to the preset temperature ratio, and the mixture generates warm water output. When the water level reaches the top of the first sensor 21, the water inlet is automatically closed. When the hot water in the heating chamber 6 is pumped out, the water inlet pipe 7 simultaneously replenishes cold water to maintain the dynamic cycle of heating-transporting-replenishing water.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
