Embodiment 1
[0041] Such as Figure 1 to Figure 3 As shown, a layered gradient porous material sweat cooling structure includes N layers of porous material layers 10, a cooling cavity 4 arranged on one side of the porous material layer 10, and a coolant supply unit 5 is arranged in the cooling cavity 4, so The coolant supply unit 5 is used to supply the coolant to the cooling cavity 4, and the porosity of the porous material layer 10 decreases layer by layer along the direction close to the cooling cavity 4, wherein N is an integer, and N≥2.
[0042] The present invention draws lessons from the high-friction characteristics of the lamination cooling structure control channel and the low-friction characteristics of the diffuse flow channel. The N-layer porous material layer 10 adopts porous material, and the porosity of the porous material layer 10 is sequentially pressed along the direction close to the cooling chamber 4. The layers are reduced, the porosity of the layer of porous material...
Embodiment 2
[0050] Such as Figure 1 to Figure 3 As shown, as a further optimization of Embodiment 1, this embodiment includes all the technical features of Embodiment 1. In addition, this embodiment also includes the following technical features:
[0051] As a preferred technical solution, the coolant supplied by the coolant supply unit 5 is a gaseous or liquid substance.
[0052] The gaseous or liquid coolant has good flow performance, which is conducive to the adequacy of heat exchange, further enhances the uniformity of heat exchange and temperature stability, and is convenient for storage.
[0053] As a preferred technical solution, the material of the N-layer porous material layer 10 is ceramic or stainless steel.
[0054] Ceramic or stainless steel has a high melting point, and it is easy to choose to make a porous material structure, which is convenient for procurement and maintenance.
[0055] As a preferred technical solution, the porosity of the N-layer porous material layer ...
Embodiment 3
[0061] Such as Figure 1 to Figure 3 As shown, this embodiment provides an aircraft, including the above-mentioned layered gradient porous material sweating cooling structure.
[0062] The layered gradient porous material sweating cooling structure of the aircraft draws lessons from the high frictional resistance characteristics of the laminated sweating cooling structure control channel and the low frictional resistance characteristic of the diffuse flow channel. The N-layer porous material layer 10 adopts porous material, and the porosity of the porous material layer 10 is along The direction close to the cooling chamber 4 decreases successively according to the layers. The layer of the porous material layer 10 close to the cooling chamber 4 has a small porosity and a large proportion of flow resistance, which is similar to the control channel of the laminate sweating cooling structure; the porous material layer 10 is far away from the cooling chamber. The layer porosity of ...
