A fuselage heat exchanger having channels for dissipating waste heat generated by fuel cells that power unmanned aerial vehicles (UAVs) or drones. A heat exchanger built into the fuselage can dissipate such waste heat. Coolant flowing through channels embedded within an aircraft fuselage panel dissipates heat to airflow around the outer surface of the fuselage.

A cooling unit includes a unit main body including a bottom portion, a peripheral wall portion rising from the peripheral edge of the bottom portion, and a sealing body for sealing an opening of the unit main body. The unit main body is joined to the sealing body through a plasticized region, and a void is formed at a position close to the unit main body with respect to a center of the plasticized region.

A thermal insulation structure includes an insulation layer having a first surface proximate a cooling device and a second surface opposing the first surface. A heater is disposed proximate the second surface, and a protective layer is disposed proximate the heater layer such that the heater layer is disposed between the insulation layer and the protective layer. The heater layer is configured to reduce frost or ice buildup on an exterior surface of the insulation layer.

graphite composite laminated heat-dissipating structure and a manufacturing method thereof are disclosed. The structure includes a metal substrate and a graphite heat-dissipating layer. The metal substrate has a first surface having a roughness ranging between 0.01 and 10 μm. The graphite heat-dissipating layer is composed of pure graphite and is directly formed on the first surface by means of physical vapor deposition using a carbon sputtering target. The graphite heat-dissipating layer has a thickness ranging between 0.05 and 2 μm. The manufacturing method includes S1: directly forming a graphite heat-dissipating layer on a first surface of a metal substrate by means of physical vapor deposition using a carbon sputtering target after the metal substrate has received plasma treatment or infrared heating; and S2: stopping the physical vapor deposition when the graphite heat-dissipating layer has a thickness ranging between 0.05 and 2 μm.

A composite thermal dissipator and a method for fabricating the same is disclosed. The composite thermal dissipator includes a molded polydimethylsiloxane (PDMS) composite material composed of a powdered metal mixed with PDMS. The method for fabricating a composite thermal dissipator includes mixing a powdered copper into liquid PDMS to form a liquid mixture, and pouring the liquid mixture into a sacrificial wax mold. The sacrificial wax mold includes wax shaped to be complementary to the composite thermal dissipator. The method also includes curing the liquid mixture within the sacrificial wax mold, and removing the composite thermal dissipator from the sacrificial wax mold by melting away the wax.

A porous heat exchanger including a single piece core extending axially is provided. The core defines a first air inlet and a first air outlet for a first fluid, a second air inlet and a second air outlet for a second fluid. The first/second fluid flows into the core from the first/second air inlet through a first/second fluid channel and flows out of the core through the first/second air outlet. The core includes solid material sheets and porous material sheets disposed alternately with the solid material sheets so each porous material sheet has an adjacent solid material sheet on each side defining one of the first fluid channel for a flow of the first fluid or the second fluid channel for a flow of the second fluid. Heat transfer occurs between the first fluid in the first fluid channel and the second fluid in the second fluid channel.
