Embodiment 1

[0038] This embodiment provides a heat exchanger, such as Figure 1 to Figure 6 As shown, the heat exchanger includes two heat exchange plate assemblies filled with heat storage material that are arranged butted against each other, namely a first heat exchange plate assembly 11 and a second heat exchange plate assembly 12 . A first through pipe 2 and a second through pipe 3 are pierced through the two heat exchange plate assemblies, and the first through pipe 2 is arranged higher than the second through pipe 3 . The two first through pipes 2 on the two heat exchange plate assemblies are arranged oppositely, and the two second through pipes 3 are arranged correspondingly.

[0039] Wherein, the heat storage material is a phase change heat storage material, preferably, the phase change heat storage material is a graphite paraffin wax material. Graphite paraffin is a kind of composite material. Graphite is made into a composite graphite paraffin material by absorbing paraffin in ...

Embodiment 2

[0050] This embodiment provides a heat exchanger whose structure is basically the same as that of Embodiment 1, such as Figure 9 As shown, it includes two heat exchange plate assemblies that are arranged butted against each other and filled with heat storage material inside, namely a first heat exchange plate assembly 11 and a second heat exchange plate assembly 12 . A first through pipe 2 and a second through pipe 3 pass through the first heat exchange plate assembly 11 .

[0051] The difference is that only the first through pipe 2 is provided on the second heat exchange plate assembly 12 , which corresponds to the first through pipe 2 on the first heat exchange plate assembly 11 . The first through pipe 2 on the second heat exchange plate assembly 12 is set as the refrigerant inlet, while the refrigerant outlet is set on the end cover 6, which is specifically arranged on the second through pipe 3 of the first heat exchange plate assembly 11. at the location. The working ...

Embodiment 3

[0054] This embodiment provides a heat exchanger, such as Figure 10 and Figure 11 As shown, its structure is basically the same as that of Embodiment 1, including two heat exchange plate assemblies that are filled with heat storage materials, respectively, the first heat exchange plate assembly 11 and the second heat exchange plate assembly 12 . A first through pipe 2 and a second through pipe 3 are pierced through the two heat exchange plate assemblies, and the first through pipe 2 is arranged higher than the second through pipe 3 . The two first through pipes 2 on the two heat exchange plate assemblies are arranged oppositely, and the two second through pipes 3 are arranged correspondingly. The first heat exchange plate assembly 11 and the second heat exchange plate assembly 12 have the same structure, and both include a heat exchange plate body 4 and a cover plate 5, and the heat exchange plate body 4 is provided with an accommodating groove 41 for accommodating heat sto...

Abstract

The invention discloses a heat exchanger, and relates to the technical field of heat exchanging devices. The heat exchanger comprises at least two heat exchanging plate components which are internally filled with thermal storage materials and are in butt joint with each other, wherein an end cover covers the outside of the heat exchanging plate component on the end part on one side, a closed heat exchanging runner is arranged between every two adjacent heat exchanging plate components, and a closed heat exchanging runner is arranged between the end cover and the adjacent heat exchanging plate component; the heat exchanger is internally provided with at least two through passages which are different in height and penetrate through all the heat exchanging runners; a coolant inlet and a coolant outlet are formed in the end cover and / or the heat exchanging plate component on the end part of the other side, and the coolant inlet is arranged to be higher than the coolant outlet. According to the heat exchanger provided by the invention, the thermal storage materials are arranged in the heat exchanging plate components, the heat exchanging runners are arranged between the heat exchanging plate components as well as between the heat exchanging plate component and the end cover, a coolant enters the heat exchanging runners and forms heat exchange together with the thermal storage materials in the heat exchanging plate components though the wall faces of the heat exchanging plate components, and the heat exchanging efficiency of the heat exchanger is ensured while the sealing requirement is realized.

Description

technical field [0001] The invention relates to the technical field of heat exchange devices, in particular to a heat exchanger. Background technique [0002] A heat exchanger is a functional device used to transfer heat between two substances without mixing the components of the two substances, and is often used for heat exchange between fluids. Heat exchangers come in a variety of styles, such as finned copper tube heat exchangers, plate heat exchangers, casing heat exchangers, and shell and tube heat exchangers. Different heat exchangers have different usage occasions and purposes. [0003] In order to achieve the maximum heat exchange effect in the current heat exchanger, the heat exchange form in which the fluid on both sides is in a flow (convection) state is required. The structure and style of the current heat exchanger cannot achieve a good heat exchange effect if one side is a solid material or a fluid in a static state. Contents of the invention [0004] An o...
