Technical Field

[0001] The invention belongs to the technical field of heat exchange energy storage, and in particular relates to a solid-state multi-channel heat exchange energy storage device. Background Art

[0002] A heat exchange device is a device that transfers heat from one fluid to another fluid. The multi-way heat exchange energy storage device is suitable for chiller water tank exchangers, air conditioning heat exchangers, air conditioning evaporator exchangers, chemical exchangers, food processing heat exchangers, power industry heat exchangers and other equipment.

[0003] The current heat exchange energy storage devices use liquid heat conduction technology. Liquid heat conduction devices are limited by the high-temperature boiling and vaporization of liquids and the freezing point of temperature. Liquid boiling will cause liquid molecules to evaporate into the atmosphere, causing air pollution. Liquid freezing will cause pipeline expansion and rupture. Liquid leakage is likely to occur during use and transportation, and heat will also be lost. The heat exchange energy storage device uses liquid heat conduction technology, which requires the additional installation of a pipeline liquid replenishing device, which also makes the structure more complicated. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and solve the problem that the existing heat exchange energy storage device is easily affected by temperature changes and interferes with the heat exchange effect.

[0006] A heat-conducting block is arranged between the first heat-conducting pipe body and the second heat-conducting pipe body, a central cavity is opened in the middle of the heat-conducting block, and the heat-conducting sleeve and the first heat-conducting pipe body are placed inside the central cavity.

[0007] In a preferred technical solution of the present invention, the first heat-conducting pipe body, the second heat-conducting pipe body and the heat-conducting block are made of solid metals such as copper, iron, aluminum, lead and tin.

[0008] In a preferred technical solution of the present invention, rectangular grooves are provided around the upper and lower ends of the heat conducting block, and an elastic sealing frame tightly attached to the surface of the second heat conducting pipe body is embedded in the groove.

[0009] In a preferred technical solution of the present invention, the first heat-conducting pipe body and the second heat-conducting pipe body respectively extend outward from either end of the shell at both ends, and a through groove is provided in the middle of the upper end of the shell and is placed directly above the heat-conducting sleeve, and the through groove is placed between the first heat-conducting pipe body and the second heat-conducting pipe body.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The heat conducting block fills the gap between the first heat conducting pipe body and the second heat conducting pipe body, and the heat conducting block enhances the stability and heat conductivity of the mutual assembly between the first heat conducting pipe body and the second heat conducting pipe body inside the shell;

[0012] This heat exchange energy storage device uses solid metal heat exchange technology to replace the existing liquid heat exchange technology. Compared with the original technology, this technology makes up for the defect that the original technology has changes in liquid form leading to changes in heat exchange effect;

[0013] Solid metal has better and faster thermal conductivity, simple structure, not easy to volatilize and cause secondary pollution, and there is no need to worry about liquid leakage during handling and transportation; the exchange temperature can far exceed the boiling temperature of the liquid, and the lower limit of the low temperature of heat exchange is lower. There is no liquid and there is no need to worry about the destructive power of freezing; the exchange efficiency is higher and the temperature range is wider. It can produce energy storage and release functions like liquid, reduce the volume share brought by the exchange, and have higher efficiency. It solves the high and low temperature limitations of heat transfer, has a simple structure, is not easy to volatilize and cause secondary pollution, does not need to worry about evaporation and lacks cumbersome protective devices and accessories, saves the cost of accessories to the greatest extent, and reduces the cost of later care and maintenance.

The heat-conducting sleeve 3 makes the spiral part of the first heat-conducting pipe body 4 close to the inner wall of the central cavity 9.

The first heat conducting pipe body 4 and the second heat conducting pipe body 5 form a multi-path heat exchange path inside the shell. The first heat conducting pipe body 4 and the second heat conducting pipe body 5 can transfer heat in reverse to each other. Solid metal adopts copper with better thermal conductivity as the heat conducting medium (copper surface electroplating protective layer). Solid metal is used instead of liquid metal as the heat conducting medium. The shape of solid metal is less affected by temperature changes.

It is also convenient to set up multiple heat exchange paths to solve the high and low temperature limitations of heat transfer. It has a simple structure and is not easy to volatilize and cause secondary pollution. The solid metal form is not affected by temperature changes, reducing the volume share caused by exchange, and is more efficient. There is no need to consider evaporation and the lack of cumbersome protective devices and accessories. The cost of accessories is saved to the greatest extent and the cost of subsequent care and maintenance is reduced.
