Specific embodiment

Relevant detailed description of the present utility model and technology contents, coordinate brief description of the drawings as follows, but appended accompanying drawing is only carried Used with explanation for reference, not for being any limitation as to the utility model.

Refer to shown in Fig. 1 and Fig. 3, the utility model provides a kind of equalizing plate structure, it mainly includes metal-back on 10th, once metal-back 20, a dividing plate 30 and a working fluid 40.

Upper metal-back 10 can be made by the good materials of thermal conductivity such as copper, aluminium or its alloy, the upper metal of the present embodiment Shell 10 has a rectangular-shaped top plate 11, but is not limited with this kind of kenel.Metal net, fibre can be laid with the lower surface of top board 11 Capillary structure (not shown) made by the dimension material such as beam or metal powder sintered thing.The another inner surface in top board 11 is connected with The support column 12 of plural number.

Lower metal-back 20 also can be made by the good materials of thermal conductivity such as copper, aluminium or its alloy, the lower gold of the present embodiment Category shell 20 has a rectangular base plate 21 and the riser 22 for being folded upward at extending from base plate 21, and lower metal-back 20 is corresponded to Metal-back 10 does contiguity sealing, so as to be formed with a cavity volume A between upper metal-back 10 and lower metal-back 20.In base plate 21 and vertical The inner surface of plate 22 is laid with the capillary knot made by the materials such as metal net, fibre bundle or metal powder sintered thing respectively Structure 23, is laid in the capillary structure 23 of the inner surface of riser 22 for a metal powder sintered thing in the present embodiment, be laid in base plate 21 The capillary structure 23 of inner surface is a metal net.

Dividing plate 30 also can be made by the good materials of thermal conductivity such as copper, aluminium or its alloy, and the dividing plate 30 of the present embodiment has There is a rectangular panel body 31, but be not limited with this kind of kenel.Offered towards metal-back 10 on foregoing in the centre position of plate body 31 One gas passage 311 in direction, the gas passage 311 of the present embodiment is a circular port, but is not limited with this kind of kenel.Separately in plate The lower surface of body 31 is laid with the capillary structure 32 made by the materials such as metal powder sintered thing.

This dividing plate 30 is laid on inside cavity volume A, i.e. the base plate 21 that the plate body 31 of dividing plate 30 is parallel to lower metal-back 20 is matched somebody with somebody Put, and the capillary structure 32 of dividing plate 30 is mutually to attach to contact with the capillary structure 23 of lower metal-back 20, and at plate body 31 and bottom A flow channel for liquids C is formed between plate 21, foregoing capillary structure 23 and capillary structure 32 is configured with this flow channel for liquids C.This Outward, the capillary structure 32 of dividing plate 30 and the capillary structure 23 of lower metal-back 20 can also not attach the kenel (figure for contacting mutually It is not shown), an interval trough B, this interval trough B and foregoing liquid are separately formed between the periphery of plate body 31 and the inner surface of riser 22 Body runner C is interconnected.Additionally, foregoing each support column 12 is connected to the upper surface of plate body 31 respectively.
