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

A micro radiator and fuel cell system with a gas-liquid separation function, including a hollow airtight container with a cooling medium inlet and a cooling medium outlet, and a round tube with two ends opened in the hollow airtight container, and the round tube is pressed The center of a circle is coiled from the inside to the outside in the same plane, or the round tube is coiled in a spiral shape from the bottom to the top along an axis; on the side wall of the coiled tube away from the center or the axis, there are more than 2 along the tangential direction The liquid outlet of the liquid outlet, the flow direction of the liquid flowing out of the liquid outlet and the flow direction of the material in the coiled tube of the liquid outlet form an acute angle; the two open ends of the tube pass through the wall of the hollow airtight container and protrude to the outside of the hollow airtight container. Using the radiator of the present invention for gas-liquid separation combines the centrifugal force and tangential drainage to separate liquid water and improve the efficiency of gas-liquid separation; at the same time, the present invention is beneficial for the cooling gas to stay for a longer period of time, and it can be separated from the spiral in the chamber. The outer wall of the tube is fully contacted to reduce the pressure head of the air pump.

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...
