Description

Technical Field

[0001] This utility model relates to a phase change heat storage plate heat exchanger insulation backpack, which can be used for temperature regulation and insulation, especially when there are fluctuations in the external temperature and the internal temperature of the equipment. It belongs to the technical field of plate heat exchangers. Background Technology

[0002] Exposed heat exchange equipment on ship decks in winter marine or polar navigation areas needs to operate in environments as low as -30°C. During operation, there will be significant fluctuations in both the external and internal temperatures of the equipment. Maintaining relative stability through temperature regulation while simultaneously insulating the equipment can extend its service life.

[0003] While existing marine phase change thermal storage devices (such as CN118463686A) possess efficient thermal storage capabilities, they suffer from drawbacks such as large size, immobility, and complex maintenance. Traditional insulated backpacks, on the other hand, often employ electric heating or chemical heat packs, which have limitations including short range and low thermal efficiency.

[0004] To address the issue of heat source temperature fluctuations that easily occur when using traditional insulation cotton to cover exposed heat exchange equipment on ship decks in winter at sea or in polar regions, there is an urgent need for a heat storage plate heat exchanger insulation backpack that can achieve miniaturized energy storage while also being easy to disassemble, replace, and maintain. The heat storage insulation backpack is filled with phase change heat storage material, which can stabilize the temperature near the phase change temperature point in addition to providing insulation. Summary of the Invention

[0005] This invention provides an insulation backpack suitable for phase change heat storage plate heat exchangers, designed to ensure more stable insulation temperature for plate heat exchangers used in open-air applications on ship decks. It also addresses the needs for miniaturization, high efficiency, and integrated operation, while facilitating easy disassembly, replacement, and maintenance.

[0006] To achieve the above objectives, the technical solution of this utility model is: a thermal insulation backpack suitable for phase change heat storage plate heat exchangers, comprising a thermal insulation backpack shell, a vacuum insulation layer, a heat storage material outlet, a heat storage backpack inner liner, a heat storage material inlet, and a phase change heat storage material. The vacuum insulation layer and the heat storage backpack inner liner are sequentially arranged inside the thermal insulation backpack shell. The thermal insulation backpack shell has a heat storage material outlet and a heat storage material inlet at both ends. In use, the phase change heat storage material is added to the heat storage backpack inner liner through the heat storage material inlet.

[0007] Furthermore, the heat storage material outlet on the shell of the thermal backpack is used to discharge the phase change heat storage material during replacement or in emergency situations.

[0008] Furthermore, the phase change heat storage plate heat exchanger insulation backpack is filled with phase change heat storage materials of different properties according to the environment in which it is used, forming a phase change heat storage plate heat exchanger insulation backpack unit.

[0009] Furthermore, the phase change heat storage material is a paraffin-based composite phase change material with a phase change temperature of 45-60℃ and a latent heat value of ≥180kJ / kg. It is filled inside the heat storage and insulation backpack and is in direct contact with the plate heat exchanger unit.

[0010] Furthermore, the outer shell of the thermal backpack is a high-strength structure, the vacuum insulation layer is an ambient temperature insulation layer, and the inner liner of the thermal storage backpack is a heat exchange contact layer; when in use, the outer shell of the thermal backpack is in contact with the environment, and the inner liner of the thermal storage backpack is in contact with the surface of the plate heat exchanger unit.

[0011] Furthermore, the outer shell of the insulated backpack uses a lightweight carbon fiber frame and is covered with fire-resistant and waterproof fabric.

[0012] Furthermore, multiple phase change heat storage plate heat exchanger insulation backpack units are wrapped around the plate heat exchanger unit.

[0013] The beneficial effects of this utility model are:

[0014] 1. Because the insulation backpack of the phase change heat storage plate heat exchanger is assembled in the form of insulation backpack units, the size of the whole device can be very compact, realizing miniaturization.

[0015] 2. Since the phase change heat storage material injected into the insulation backpack of the phase change heat storage plate heat exchanger can be selected according to the environment and working conditions, the application scenarios can be varied. Attached Figure Description

[0020] like Figure 1As shown in Figure 2, this utility model provides a thermal insulation backpack suitable for phase change heat storage plate heat exchangers, including a thermal insulation backpack shell 1, a vacuum insulation layer 2, a heat storage material outlet 3, a heat storage and insulation backpack inner liner 4, a heat storage material inlet 5, and a phase change heat storage material 6.

[0021] The thermal backpack consists of an outer shell, a vacuum insulation layer, a heat storage material outlet, a heat storage and insulation backpack inner liner, and a heat storage material inlet. Together, they form a whole phase change heat storage plate heat exchanger thermal backpack.

[0023] The inner liner 4 of the thermal backpack shell 1 is filled with suitable phase change thermal storage material 6 through the thermal storage material inlet 5. In case of replacement or emergency, the material is discharged through the thermal storage material outlet 3. Figure 2 .

[0024] Preferably, the phase change heat storage material 6 is a paraffin-based composite phase change material with a phase change temperature of 45-60℃ and a latent heat value of ≥180kJ / kg. It is filled inside the inner liner 4 of the heat storage and insulation backpack and is in direct contact with the plate heat exchanger unit.

[0025] Preferably, the outer shell 1 of the insulated backpack is a structural strength, the vacuum insulation layer 2 is an ambient temperature insulation layer, and the inner liner 4 of the heat storage insulated backpack is a heat exchange contact layer. During use, the outer shell 1 of the insulated backpack contacts the environment, and the inner liner 4 of the heat storage insulated backpack contacts the surface of the plate heat exchanger unit.

[0026] Preferably, the outer shell 1 of the thermal backpack is made of a lightweight carbon fiber frame and covered with fireproof and waterproof fabric.

[0027] Preferably, the insulation backpack is suitable for phase change heat storage plate heat exchangers. Different phase change heat storage materials with different properties are added according to the environment in which they are used to form a phase change heat storage plate heat exchanger insulation backpack unit.

[0028] Preferably, the plate heat exchanger unit is composed of multiple parallel corrugated plates stacked together, with fluid channels formed between the plates.

[0029] Insulation backpacks suitable for phase change heat storage plate heat exchangers can be made into multiple units to completely cover the plate heat exchanger, such as... Figure 3 As shown.

[0030] Multiple phase change heat storage plate heat exchanger insulation backpack units can effectively wrap the plate heat exchanger, effectively insulate the equipment and maintain a relatively stable temperature.

[0031] The insulation backpack for phase change heat storage plate heat exchangers differs from similar products in that it uses internally injected phase change material to regulate and stabilize the temperature while insulating the equipment; the backpack is miniaturized and modular for easy on-site deployment; and the phase change material inside is replaceable for use in different scenarios.

[0032] The main features of this utility model of an insulated backpack suitable for phase change heat storage plate heat exchangers are:

[0033] 1. Because the insulation backpack of the phase change heat storage plate heat exchanger is assembled in the form of insulation backpack units, the size of the whole device can be very compact, realizing miniaturization.

[0034] 2. Since the phase change heat storage material injected into the insulation backpack of the phase change heat storage plate heat exchanger can be selected according to the environment and working conditions, the application scenarios can be varied.
