Specifically, the temperature equalizing plate 220 is a metal temperature equalizing plate 220, and may be, for example, a copper plate or an aluminum plate, which has a good thermal conductivity. The vapor plate 220 can separate more than two breast milk bags 100 within the chamber 211 from each other. Contacts the breast milk bag 100 while separating adjacent breast milk bags 100 from each other within the thermally conductive housing 210. When the inner side walls of the temperature equalizing plate 220 and the heat conducting shell 210 are in contact with the breast milk bag 100, cold can be quickly transferred to breast milk in the breast milk bag 100. In addition, after the temperature equalizing plate 220 in the heat-conducting shell 210 is removed, the breast milk bag 100 with larger capacity can be loaded into the heat-conducting shell 210 for cooling and storage and transportation, that is, the breast milk bag 100 with larger capacity can be cooled and stored and transported.
Further, the bottom of the vapor chamber 220 is connected to the bottom wall of the heat conductive housing 210. Part of cold energy of the heat conduction shell 210 is conducted to the temperature equalizing plate 220 through the bottom wall of the heat conduction shell, and then the cold energy is conducted to the breast milk bag 100 which is in contact with the temperature equalizing plate 220 through the temperature equalizing plate 220, so that a good cooling effect on the breast milk bag 100 is achieved, and the temperature equalizing property is good.
In addition, the temperature-equalizing plate 220 may be, for example, a straight-line-shaped temperature-equalizing plate 220, and when 4 breast milk bags 100 filled with breast milk are placed in the cavity 211 of the heat-conducting casing 210, the temperature-equalizing plate 220 is placed in the middle of the cavity 211, 2 breast milk bags 100 filled with breast milk are placed between one side surface of the temperature-equalizing plate 220 and the first convex hull 212, and the remaining 2 breast milk bags 100 filled with breast milk are placed between the other side surface of the temperature-equalizing plate 220 and the second convex hull 213.

In addition, the temperature-uniforming plate 220 can also be, for example, a cross-shaped temperature-uniforming plate 220, when, for example, 4 breast milk bags 100 filled with breast milk are placed in the cavity 211 of the heat-conducting shell 210, the temperature-uniforming plate 220 is installed in the cavity 211, the bottom of the temperature-uniforming plate 220 is in contact with the bottom wall of the heat-conducting shell 210, the temperature-uniforming plate 220 can realize mutual isolation of the 4 breast milk bags 100, one part of the side wall of the breast milk bag 100 is in surface-to-surface contact with the inner side wall of the heat-conducting shell 210, and the other part of the side wall of the breast milk bag 100 is in surface-to-surface contact with the temperature-uniforming plate 220, so that.
In one embodimentIn the above embodiment, the heat conductive housing 210 is formed by stretching aluminum material. Specifically, the stretching width D is first determined1Ratio to the drawing depth H
For example, 2.5 to 2.6, the soft aluminum plate is stretched to form the main body of the heat conductive housing 210, and then the two opposite inner sidewalls of the main body are stretched to form the first convex hull 212 and the second convex hull 213. Thus, the heat conducting shell 210 has good heat conductivity, and can reduce the cold conduction loss on the inner container 200 as much as possible.
As an alternative, the heat-conducting casing 210 is formed by welding a plurality of heat-conducting metal blocks. Specific examples of the heat conductive metal block include a copper block and an aluminum block.

In addition, the semiconductor cooler 400, the cold guide block 500 and the heat dissipation assembly are combined to the housing 300, so that the whole volume is small, the weight is light, and the carrying is convenient.
Further, the shape of the end surface of the cold guide block 500 contacting the cold end surface is adapted to the cold end surface. That is, the area of the end surface of the cold block 500 contacting the cold end surface is the same as the area of the cold end surface. The other end surface of the cold guide block 500 contacts with the bottom of the inner container 200. Thus, a thermal short between the cold block 500 and the heat sink can be avoided.

In one embodiment, one end surface of the cold guide block 500 is in close contact with the cold end surface, and the other end surface of the cold guide block 500 is in close contact with the outer sidewall of the inner container 200. The end surface area S1 of the cold guide block 500 contacting with the cold end surface is smaller than the end surface area S2 of the cold guide block 500 contacting with the outer side wall of the inner container 200.
Further, a wing 540 is formed by extending the side of the cold guide block 500 facing one end of the inner container 200. Specifically, both side surfaces of one end of the inner container 200 are outwardly extended to form wing portions 540, and both wing portions 540 are connected to the inner container 200 by the connection member 230. The wing 540 increases the end surface area of the end of the cold guide block 500 facing the inner container 200 to a certain extent, so that the contact area of the cold guide block 500 and the outer side wall of the bottom of the inner container 200 can be increased, and the cold conduction thermal resistance is reduced, thereby being beneficial to the cold guide block 500 to conduct cold to the inner container 200. In addition, the cold energy is favorably and uniformly transmitted to the bottom of the inner container 200, and the refrigerating performance of the inner container 200 is enhanced. In addition, the wing 540 can facilitate the connecting member 230 to connect and assemble the cold block 500 and the inner container 200 together.

The connecting member 230 is, for example, a steel wire rope or a plastic rope, and may also be directly tied to the first mounting portion 240 and the second mounting portion 250. Furthermore, a groove 541 is disposed on a side wall of the wing 540 facing away from the inner container 200, and the connecting member 230 is disposed in the groove 541, so that the wing 540 can be stably installed and fixed on the inner container 200.
In one embodiment, referring to fig. 9-13, the breast milk cooler further includes a thermal insulation layer 710.

Further, the insulation layer 710 is a foamed insulation layer 710. Thus, the pressure generated in the foaming process of the foaming insulation layer 710 is applied to the wing part 540 of the cold guide block 500, so that the cold guide block 500 is more tightly jointed with the bottom of the liner 200, and the cold conduction thermal resistance is reduced; in addition, the foaming insulation layer 710 enables the cold guide block 500 and the inner container 200 to be combined into a whole, and the structure is firmer and more reliable. Specifically, the housing 300 includes a removable partition 310, and the mounting opening 311 is disposed on the partition 310.
In one embodiment, the heat dissipation assembly includes a heat sink 610 and a heat dissipation fan 620. The heat sink 610 is in contact with the hot end face for carrying away heat on the hot end face. The heat dissipation fan 620 is used for dissipating heat from the heat sink 610. That is, the heat dissipation fan 620 blows air through the heat sink 610 to take away heat from the heat sink 610, thereby dissipating heat. The air outlet surface of the heat dissipation fan 620 may directly face the heat sink 610, may be diagonally opposite to the heat sink 610, or may use the air guiding plate 630 to guide the air outlet of the heat dissipation fan 620 to flow through the heat sink 610.
Further, referring to fig. 9, the heat sink 610 includes a heat dissipation plate 611 and a plurality of fin plates 612 disposed on the heat dissipation plate 611 at intervals.
