Embodiment 1

[0043] figure 1 is the front view of this embodiment, figure 2 is a top view of this embodiment. In this embodiment, a phase change cooling device includes a housing 1, an energy storage material 5, a water inlet pipe 3 and a water outlet pipe 4, the energy storage material 5 is arranged inside the housing 1, and the water inlet pipe 3 is arranged in the housing 1 on the water inlet end plate 101, and the water outlet pipe 4 is arranged on the water outlet end plate 102 of the housing 1; wherein: one end of the water inlet pipe 3 and the water outlet pipe 4 in the housing 1 communicates with a shunt assembly 2 respectively The splitter assembly 2 is arranged at the middle position of the height and width of the inner space of the housing 1, the standpipe 201 is evenly distributed along the width direction of the housing 1, and the horizontal tube 202 is evenly distributed along the height direction of the housing 1; the two splitter assemblies 2 and Splitter plates 6 are ar...

Embodiment 2

[0051] The cooling system is mainly divided into cold storage process and cooling process.

[0052] Cold storage process such as Figure 4 As shown, the cold water from the chiller 8 passes through the one-way valve, the first hose, the water pump, the second hose, the valve, etc., and then enters the phase-change cold storage device described in Embodiment 1, and transfers heat energy to the energy storage material 5 After that, the temperature of the cold water rises and returns to the unit, so the cycle is repeated. During the circulation process, judge whether the energy storage material 5 has realized excessive cold storage according to the temperature collected by the temperature sensor 7, and also judge whether there is temperature stratification in the energy storage material 5, and adjust the speed of the water pump or the opening of the valve according to the temperature stratification , and then adjust the distribution of water flowing through the phase change anim...

Abstract

The invention discloses a phase-change cold storage device and a cold supply system with same. The phase-change cold storage device comprises a casing, an energy storage material, a water inlet pipe and a water outlet pipe, wherein the energy storage material is arranged in the casing; the water inlet pipe is arranged on a water inlet end plate of the casing, and the water outlet pipe is arranged on a water outlet end plate of the casing; flow distribution assemblies are respectively arranged at one side, near the water inlet end plate, and one side, near the water outlet end plate, in the casing; the flow distribution assembly at one side near the water inlet end plate is communicated with the water inlet pipe, and the flow distribution assembly at one side near the water outlet end plate is communicated with the water outlet pipe; a flow distribution plate is arranged between each flow distribution assembly and the energy storage material; water distribution holes are formed in one side, away from the flow distribution plate, of each flow distribution assembly. The phase-change cold storage device has the advantage that by adopting the scheme, the water distribution holes are formed in one side away from the flow distribution plate, and the water flow is returned back and sent into the flow distribution plate, so that the water flow of the energy storage material is uniformly distributed, the problem of temperature stratification produced by the energy storage material is effectively inhibited, the cold storage efficiency and effect are improved, and the service life of the energy storage material is prolonged.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a phase-change cooling device and a cooling system using the same. Background technique [0002] The working principle of the phase change animal cooling device is to arrange energy storage materials in a closed cavity, and then pass cold water into the cavity. After the cold water transfers cold energy to the energy storage materials, the temperature rises and then leaves the cavity. After the energy storage material absorbs the cold energy, the temperature drops, and the cold energy is transferred from the cold water to the energy storage material. Transfer the phase-change animal cooling device with cold energy to the user, and pass normal temperature water into the cavity. When the normal temperature water passes through the low-temperature energy storage material, it absorbs the cold energy of the energy storage material, and the temperature drops, and the te...
