Vehicle air conditioner with flow area adjustment of fluid in heating heat exchanger
First Claim
1. An air conditioner for a vehicle having a passenger compartment, comprising:
- an air conditioning case for defining an air passage through which air flows into the passenger compartment;
a heating heat exchanger, disposed in the air conditioning case, for heating air using a fluid flowing therein as a heating source; and
a flow control member disposed within the heating heat exchanger to divide the heating heat exchanger into a first area where the fluid flows and a second area where the fluid does not flow, wherein;
the flow control member changes a ratio between the first area and the second area.

Abstract
In a vehicle air conditioner, a flow control member is disposed in an inlet tank of a heating heat exchanger for heating air to be blown into a passenger compartment using a fluid as a heating source. In the heating heat exchanger, a ratio between a first area where the fluid flows, and a second area where the fluid does not flow is changed by controlling an operation position of the flow control member. Thus, a flow ratio between hot air from the first area of the heating heat exchanger and cool air from the second area thereof can be adjusted, so that the temperature of air blown into the passenger compartment can be adjusted.

24. An air conditioner for a vehicle having a passenger compartment, comprising:
-
an air conditioning case for defining an air passage through which air flows into the passenger compartment;
a heating heat exchanger, for heating air using a fluid flowing therein as a heating source, disposed in the air conditioning case, the heating heat exchanger including a core portion having a plurality of tubes through which the fluid flows to heat air, and a tank member for distributing the fluid into and for collecting the fluid from the tubes; and
a flow control member disposed in the tank member to be movable in the tank member so that an inner space of the tank member is partitioned into plural spaces in a tube arrangement direction where the tubes are arranged, wherein;
the flow control member is moved linearly in the tube arrangement direction to change a ratio between a first number of the tubes in which the fluid flows, and a second number of the tubes in which the fluid does not flow. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 42)

35. An air conditioner for a vehicle having a passenger compartment, comprising:
-
an air conditioning case for defining an air passage through which air flows into the passenger compartment;
a heating heat exchanger, for heating air using a fluid flowing therein as a heating source, disposed in the air conditioning case, the heating heat exchanger including a core portion having a plurality of tubes through which the fluid flows to heat air, and a tank member for distributing the fluid into and for collecting the fluid from the tubes; and
a flow control member disposed in the tank member to be rotatable around a rotation axis that is parallel to a tube arrangement direction where the tubes are arranged, wherein;
the flow control member has a dimension in an axial direction, corresponding to a length of the tubes in the tube arrangement direction; and
the flow control member is rotated in the tank member to change a ratio between a first number of the tubes in which the fluid flows, and a second number of the tubes in which the fluid does not flow. - View Dependent Claims (36, 37, 38, 39, 40, 41)
