Multi-tube heat exchanger and air conditioner having the same
First Claim
1. A heat exchanger system comprising:
- a housing, said housing defining a plurality of inlet or outlet streams for air flow;
a multi-tube heat exchanger disposed in said housing, said multi-tube heat exchanger having an entrance side at the inlet of said housing and an exit side at the outlet of said housing, said entrance side and said exit side in a passage direction of air subjected to heat exchange, said multi-tube heat exchanger comprising;
a pair of tanks spaced from each other; and
a plurality of heat transfer tubes fluidly interconnected between said pair of tanks, said plurality of heat transfer tubes being arranged so that a first tube-arrangement surface is formed on the entrance side of said multi-tube heat exchanger and a second tube-arrangement surface is formed on the exit side of said multi-tube heat exchanger, at least one of said first and second tube-arrangement surfaces being formed as two or more surfaces different from each other, and wherein the air flow subjected to heat exchanger is separated or joined in said multi-tube heat exchanger.

Abstract
A multi-tube heat exchanger includes a pair of tanks and a plurality of heat transfer tubes fluidly interconnected between the tanks. The heat transfer tubes are arranged so that at least one of tube-arrangement surfaces formed on entrance and exit sides of the heat exchanger in a passage direction of air subjected to heat exchange is formed as two or more surfaces different from each other, and air flow is separated or joined in the multi-tube heat exchanger. An air conditioner according to the present invention has such a multi-tube heat exchanger in an air path. The multi-tube heat exchanger can be made smaller while a desired heat exchange property can be maintained. An air conditioner having such a heat exchanger also can be made smaller.
