Embodiment
Embodiment shown in the drawings is the vehicle fuel battery heap of 15kW, and is two by nonconducting end plate 1, metal
Can produce the heat of about 15KW during this operation of fuel cells, because the metal double polar plates capacity of heat transmission is very strong, these heats are transmitted to rapidly on the fin of fuel cell pack outer package during work, the wind speed that produces in the vehicle ' is dispersed into these heats in the air rapidly, realizes the heat radiation of battery.
This fuel cell natural cooling effect estimation:
Following table is the coefficient of heat conduction of several different metal materials.
As can be seen from the table, silver and copper are best Heat Conduction Materials, secondly are gold and aluminium, but gold, silver are too expensive, and copper is very heavy again, processed complex.Therefore aluminum alloy materials is optimal selection.What present embodiment adopted is 1070 type aluminium alloys, and its conductive coefficient is 226.The average thickness of fin is 12.5mm, the upper and lower sides area in the battery outside is 1.68 square metres, and generally speaking, the battery surface temperature is 80 degrees centigrade during the fuel cell maximum power operation, automobile in running at high speed during steady heat transfer the fin surface temperature be 70 degrees centigrade, by the heat conduction formula:
Q＝K*A*T/L
Can obtain the heat that is transmitted to fin surface each second is 30KW.In actual the use, battery does not reach so high heat, and the natural heat dissipation mode of the fuel cell of this embodiment has given out the heat that most fuel cell produces.
