Disclosed herein is an integrated multiple heat exchange device and a fuel cell system using the same. The integrated multiple heat exchange device includes a plurality of heat exchangers for consecutively collecting heat contained in a plurality of gases that are present in the fuel cell system and that have different temperatures, wherein the plurality of heat exchangers are separated from each other, a porous separator is placed between the plurality of heat exchangers such that condensate is collected at a lowermost heat exchanger, and a coolant line penetrates a separator to pass through all the plurality of heat exchangers.

Heat exchange device and fuel cell system using the same

Disclosed are a fuel supply module that may maintain an entrainment ratio in a constant range even under a load change, and a fuel reforming apparatus for a fuel cell using the same. The fuel supply module includes: a water vapor storage for storing water vapor therein; a fuel storage for storing fuel therein; a mixer having a first inlet, a second inlet, and an outlet; a first inlet pipe for connecting the water vapor storage and the first inlet of the mixer with each other; a second inlet pipe for connecting the fuel storage and the second inlet of the mixer with each other; an outlet pipe connected to the outlet of the mixer; and a bypass pipe having one end connected to the first inlet pipe and the other end connected to the outlet pipe.

Fuel supply module, and fuel reforming apparatus for fuel cell using the same

A water circulation system associated with a refrigerant cycle that includes an intermediate heat exchanger having a triple-pipe shape in which three independent flow passages are formed by three pipes having a concentric axis and different diameters. Accordingly, three fluids flowing through the three independent flow passages can exchange heat with each other at the same time through the intermediate heat exchanger and heat exchange capacity of the intermediate heat exchanger can selectively be varied.

Water circulation system associated with refrigerant cycle

A water cooling type air conditioner is provided. The water cooling type air conditioner includes first and second heat exchangers, a refrigerant pipe, and a direction controlling unit. The first heat exchanger performs heat exchange between air and refrigerant. The second heat exchanger performs heat exchange between the refrigerant and cooling water. The refrigerant pipe is connected between the first heat exchanger and the second heat exchanger to guide a flow of the refrigerant. The direction controlling unit is disposed on one side of the second heat exchanger and controls the refrigerant and the cooling water flowing inside the second heat exchanger to flow in respectively opposite directions.
