Embodiment Construction

[0033] Best Mode for Carrying Out the Invention

[0034] Next, embodiments of the heat exchanger of the present invention will be described with reference to the drawings.

[0035] Figure 1 to Figure 6 One embodiment of the heat exchanger of the present invention is shown. The illustrated heat exchanger has a core 10 and side tanks 11 disposed at the ends of the core 10 . On the core part 10, a plurality of tubes 12 and a plurality of fin units, that is, external fins 13 are alternately laminated in the first horizontal direction A1 to form a laminated part, and a side plate 14 is disposed on the outermost layer of the laminated part. . Each tube 11 forms a heat exchange passage for performing heat exchange with the heat exchange medium in the vertical direction, which is the second direction A2 perpendicular to the first direction A1.

[0036] The side compartment 11 is formed by joining two forming panels 15 and 16 and is fixed on the side panel 14 . Inside the side co...

Abstract

A heat exchanger comprises: a core part (10) for heat exchange of a heat exchange medium and having a plurality of pipes (12) for forming passages for heat exchange; a side tank (11) disposed on an end part of the core part (10), while the side tank has lead passages (17, 18) communicating with the pipes; and a flange (19) joined with the side tank and having end holes (22, 23) communicating with the lead passages in an intercross direction. A commutation part (24, 28) is provided in a part of the lead passages close to the end holes for commutating the heat exchange medium.

Description

technical field [0001] The present invention relates to a heat exchanger capable of reducing noise, and more particularly to a heat exchanger provided with side tanks at the end of a core having a plurality of tubes forming heat exchange passages. Background technique [0002] Such heat exchangers are known in the form shown in FIGS. 7 to 10 . The illustrated heat exchanger has a core 60 and side chambers 70 disposed at the ends of the core 60 . The core 60 is provided with a side plate 80 on the outermost layer of the lamination part formed by alternately laminating the plurality of tubes 71 and the plurality of fin units, ie, the external fins 72 , in the first horizontal direction B1 . Each tube 71 extends in a second direction B2 perpendicular to the first direction B1, that is, an up-down direction. [0003] The side tank 70 is formed by joining two profiled panels 73 and 74 and is fixed on the side panel 80 . Inside the side compartment 70, there are an introduction...
