Problems solved by technology

[0010] However, in the conventional invention, the cooling air passing through the core of the condenser does not sufficiently flow through the louvers of the core of the radiator but passes as it is, so there is a problem that the heat exchange efficiency is poor.
[0011] In addition, although the protruding part of the conventional invention contributes to the enlargement of the radiating cross-sectional area, it does not have the function and effect of the louver that reliably guides the cooling air to the core of the radiator.
[0012] In addition, this problem also occurs when the radiator and the condenser have corrugated fins separately.

Abstract

Heat exchangers (1, 2) for a vehicle in which corrugated fins (3) stacked alternately with the tubes (1d, 2d) of core parts (1a, 2a) are provided with louvers (3a, 3b). The corrugated fins (3) are provided to be projected from the core parts (1a, 2a) to the upstream side of cooling air. The projected portion of the fins is provided with projections (3c, 3d) for converging the cooling air to the downstream side.

Description

technical field [0001] The present invention relates to a vehicle heat exchanger, and more particularly to a vehicle heat exchanger having a louver on a corrugated fin at a core of the heat exchanger. Background technique [0002] Conventionally, there are known technologies for vehicle heat exchangers in which louvers are provided on corrugated fins laminated alternately with the respective tubes of the core (see Patent Documents 1 to 5). [0003] In addition, in the corrugated fins shared by the radiator (radiator) and the condenser as a heat exchanger, a circular protrusion is sometimes provided between the core of the radiator and the core of the condenser to expand heat dissipation. area, thereby improving cooling performance (see Patent Document 6).
