Description

condenser structure

technical field

The present invention relates to a condenser, in particular to a condenser applied to a fuel cell, which is provided with a plurality of condensing elements to provide gaseous water condensation of cathode products.

Background technique

The condenser used in the fuel cell device uses the principle of heat transfer, so that the high-temperature gaseous water generated by the fuel cell device at the cathode passes through the multiple channels between the multiple fins of the condenser, and the low-temperature fins are contacted. Condenses into water, allowing the water to be recycled and reused. Therefore, the structural design of the multiple fins of the condenser has a great influence on the water recovery rate.

U.S. Patent Early Publication US20050208352 "Fuel Cell System (Fuel Cell System)" has disclosed a cathode-side radiator (Cathode-side radiator), which is used to provide heat dissipation for high-temperature gaseous water, so that gaseous water can condense and become liquid water. US20050208352 has disclosed at which temperature the temperature of the cathode heat sink itself should be set so as to meet the condensation requirement. However, US20050208352 does not propose a specific method for the specific structure of the cathode heat sink.
