Description

Technical field

[0002] The utility model relates to the technical field of drinking water equipment, in particular to the technical field of a heat exchanger device which utilizes phase change materials to perform heat storage and heat exchange. [Background Technology]

[0004] As living standards improve, the demand for energy increases. However, the limited energy and resources are a problem that needs to be faced worldwide. In addition to developing new energy sources, more consideration needs to be given to energy conservation. The use of phase change materials for heat storage and heat release has also been a technical field that has received considerable attention in recent years. Among them, heat storage technology mainly uses phase change energy storage technology, and phase change materials are widely used in many fields, especially in the fields of thermal management and energy storage. The so-called phase change material is a type of material with thermal conductivity that can absorb or release large amounts of heat from the surrounding environment by changing its own phase state, thereby achieving thermal management function.

[0005] Phase change materials include solid-liquid phase change materials and solid-solid phase change materials. Solid-liquid phase change materials refer to materials that undergo solid-liquid phase changes during the process of absorbing and releasing heat. When using solid-liquid phase change materials, the system control is more complicated due to the fluidity of the phase change materials when melted. Solid-solid phase change materials do not need to consider the issue of fluidity. However, since solid-solid phase change materials have no fluidity, there are concerns about low heat conduction and utilization. Once the structure is too thick or the design is unreasonable, dead zones with low material utilization will appear, reducing the overall utilization of the system. [Summary of the invention]

[0007] In response to the shortcomings and problems of existing solid-solid phase change material heat exchanger devices, the utility model proposes a phase change material heat exchanger device with an improved design structure, which can improve the heat storage utilization rate of the phase change material, and simplify the manufacturing process of the device as a whole to reduce manufacturing costs.

[0008] The phase change material heat exchanger device involved in the present utility model is characterized in that the device includes a flow channel shell, a phase change material and an outer shell.

[0009] The flow channel housing is made of a material with high thermal conductivity and is die-casted with a spiral groove. Two pieces of corresponding materials are attached and pressed together to form a flow channel housing with liquid flowing inside.

[0010] The housing: a sealed housing is assembled outside the flow channel housing;

[0011] The phase change material is poured between the flow channel shell and the outer shell to fill the gap between the two;

[0012] The flow channel housing is formed by pressing ceramic and metal materials.

[0013] The flow channel housing is divided into a first sheet and a second sheet, and a groove is provided between the first sheet and the second sheet to form a space suitable for liquid circulation.

[0014] The first sheet has a groove structure, and the second sheet is flat, forming a flow space composed of half of the groove.

[0015] The first sheet material has a groove structure, and the second sheet material has a groove structure of the same size and corresponding distribution position, forming a flow space formed by the two grooves.

[0016] The two sheet materials constituting the flow channel housing are rectangular, and evenly distributed and coiled grooves are pressed thereon.

[0017] The phase change material fills the gap outside the groove of the flow channel housing and / or the surface outside the groove.

[0018] The phase change material heat exchanger involved in the utility model separates water and phase change material, and at the same time disperses and evenly distributes the phase change material in the groove and surface of the middle pipe, evenly covering the flow channel shell inside. When the liquid passes through the flow channel, there is no heat exchange dead corner. The flow channels are evenly distributed and tightly realize water flow through the entire heat exchanger, with high space utilization and good heat exchange effect.
