Embodiment

[0030] The mosquito-repellent coil 1, drainage pipe 2, baffle plate 3 and shell 4 of the radiator are all made of stainless steel and formed by 3D printing technology. The coil inlet 5 is the outermost ring pipe of the mosquito coil 1 extending perpendicular to the plane direction of the mosquito coil 1 through a 90-degree corner, and the coil outlet 5 is the innermost ring pipe of the mosquito coil 1 perpendicular to the mosquito coil through a 90-degree corner Coil 1 extends in the plane direction, with a wall thickness of 0.3mm and a diameter of 4mm. Mosquito coil 1 is set around 5 circles, and the outer diameter of the circle can be set to 50mm; drainage tube 2 is inserted into the outer wall of the coil along the tangential direction of the coil, and penetrates In the channel of the mosquito coil 1, and extend perpendicular to the plane of the mosquito coil 1 through a 90-degree corner, set up one per week, in a straight line with the inlet and outlet of the mosquito coil ...

Abstract

The invention relates to a micro heat dissipator with a gas-liquid separating function and fuel battery system. The system comprises a hollow closed container with a cooling medium inlet and a cooling medium outlet. A circular tube which is opened at two ends is formed in the hollow closed container, the circular tube coils circularly from inside to outside in a same plane according to a center of a circle or the circular tube coils spirally from bottom to top along axis; more than two liquid outlets are formed in the side wall winding the circular tube along the tangential direction far from the center of the circle or the axis, and the flowing direction of a liquid flowing out of each liquid outlet and the flowing direction of a material in the circular tube winding the liquid outlet form an acute angle; the two opened ends of the circular tube pass through the wall of the hollow closed container and extend out of the hollow closed container. By adopting the heat dissipator to perform gas-liquid separation, liquid water is separated by combining the action of a centrifugal force and a drainage action of a tangent line, so that the gas-liquid separating efficiency is increased; meanwhile, according to the micro heat dissipator provided by the invention, cooling gas stands for a longer time to be in full contact with an outer wall of the spiral tube in the chamber, so that the pressure head of the air pump is reduced.

Description

technical field [0001] The invention belongs to the innovative technology of fuel cell components. To be precise, it belongs to the innovative technology of gas-liquid separator and radiator of proton exchange membrane fuel cell. Background technique [0002] At present, the proton exchange membrane fuel cell has become a new energy research hotspot due to its high energy conversion efficiency, no pollution, low noise and many other advantages. Among them, low-power proton exchange membrane fuel cells have a considerable market prospect because of their portable power sources that can charge mobile appliances such as notebooks and mobile phones. [0003] Reducing the size is always the goal of portable fuel cell system optimization. In addition to effective use of space, the miniaturization of the internal components of the system is the fundamental solution to the "slimming" of portable fuel cells. At present, the fuel cell radiator generally adopts the form of metal tube...
