and the heat transfer working medium is filled in the storage cavity 220 formed by the heat source combination plate 200 and the substrate 100.
Specifically, in this embodiment, the substrate 100 includes the first surface and the second surface that are oppositely disposed, and the substrate 100 is provided with a plurality of substrate grooves 110 that penetrate through the substrate 100 and are separated by the substrate wall 130. In this embodiment, the vertical spacing distance between the adjacent substrate grooves 110 is greater than the horizontal spacing distance between the adjacent substrate grooves 110, but the present invention is not limited to this, and the vertical spacing distance may be set according to actual requirements, for example, the vertical spacing distance is equal to or less than the horizontal spacing distance. The step structure 120 is disposed in the substrate groove 110, and the heat source bonding board 200 is fixed in the substrate groove 110 by combining the step structure 120. In order to be able to dissipate heat separately from a plurality of heat sources, the number of the substrate recesses 110 should be not less than 2.
The surface of the heat source combination plate 200 facing the first surface is in contact with a heat source to form a heat source contact surface, the capillary structure 211 is laid on the other surface of the heat source combination plate 200 opposite to the heat source contact surface, and the capillary structure 211 provides capillary force to disperse heat transfer working media to the whole surface of the heat source combination plate 200.

The condensing fin groups 300 are fixed on the second surface of the base plate 100, the condensing fin groups 300 are arranged corresponding to the base plate grooves 110, each condensing fin group 300 spans all the base plate grooves 110 in the same vertical direction and is fixed on the second surface, and each condensing fin group comprises a plurality of condensing fins 310 separated by the transverse walls 320; the condensation fin 310 is provided with a condensation channel 312 and an opening, the condensation channel 312 and the transverse gap at the top of the condensation fin 310 are gas flow channels 311, the condensation channel 312 and the transverse gap at the bottom of the condensation fin 310 are liquid flow channels 313, the opening faces the substrate groove 110 and is fixed on the two sides of the substrate groove 110, and the condensation fin 310 is correspondingly arranged to be combined with the substrate groove 110 and the heat source combining plate 200 to form a heat dissipation partition. The combination of the plurality of condensing fins 310 may be formed by welding all the condensing fin groups 300 into a whole by connecting plates, or may be formed in other manners, which is selected according to the actual situation, and is not particularly limited herein.
The heat transfer working medium is filled in the storage cavity 220 formed by the heat source combination plate 200 and the substrate 100, and the heat source is radiated by utilizing the property that the heat transfer working medium absorbs heat through phase change and the temperature of the heat transfer working medium is kept unchanged.
In detail, after the welding and assembling of the modular partitioned phase change heat radiator are completed, the modular partitioned phase change heat radiator is subjected to vacuum pumping treatment and then is fused and sealed to avoid air entering. Taking one of the heat dissipation partitions as an example, the working principle of the modular partitioned phase change heat sink is analyzed. When the heat source combination plate 200 is heated, the heat transfer working medium on the surface of the heat source combination plate 200 absorbs latent heat to evaporate, the gaseous heat transfer working medium enters the condensation fins 310 from the opening, is condensed and liquefied in the condensation fins 310 to release heat, and exchanges heat with the cooling air flowing through the outer surface of the condensation fins 310 to dissipate the heat to the surrounding environment; under the action of gravity, the condensed and liquefied liquid heat transfer working medium is collected at the bottom of the condensing fins 310 along the condensing channel 312 and flows back to the storage cavity 220 along the liquid flow channel 313 at the bottom, and the heat transfer working medium in the storage cavity 220 flows back and spreads to the surface of the whole heat source combination plate 200 under the action of the capillary structure 211 and absorbs heat for evaporation again, so that the circulation of evaporation heat absorption and condensation heat release is continuously carried out, and dynamic balance is achieved.

When the traditional radiator provides heat dissipation for different vertical heat sources, the temperature of a heat transfer working medium can be continuously increased when the heat transfer working medium flows to an upper heat source from a lower heat source under the action of capillary action, so that the heat dissipation efficiency of the upper heat source is poor, and the phenomenon of uneven vertical heat dissipation is caused. In the embodiment, the vertical upper heat source and the vertical lower heat source are correspondingly provided with independent heat dissipation subareas, so that the phenomenon of uneven vertical heat dissipation is avoided, and the overall heat dissipation efficiency of the modular type subarea phase change heat radiator is improved.

In addition, the heat source combination plates 200 are arranged upwards in the same horizontal direction, so that the pressure of gaseous heat transfer working medium in the heat dissipation cavity on the heat source combination plates 200 can be dispersed, and the safety and reliability of the modular partitioned phase change heat radiator are improved.
The modular partitioned phase-change radiator integrates a plurality of radiating partitions into the same radiator, so that the modular partitioned phase-change radiator is small in size, low in cost and convenient to apply on a large scale.
