Embodiment Construction

[0026] Hereinafter, this embodiment will be described with reference to the drawings. In order to facilitate understanding and description, the same components are given the same symbols as much as possible in the respective drawings, and repeated descriptions are omitted.

[0027] The heat exchanger 10 of the present embodiment is configured as an evaporator that constitutes a part of a refrigeration cycle (not shown) configured as an air conditioning system of a vehicle. Refrigerant as a heat medium is sent to the heat exchanger 10 by a compressor (not shown) arranged in a part of the refrigeration cycle. The heat exchanger 10 cools the air by evaporating the supplied refrigerant inside and exchanging heat between the refrigerant and the air.

[0028] In addition, the heat exchanger 10 may be configured as a heat exchanger other than the above-mentioned evaporator. For example, the heat exchanger 10 may be configured as a radiator for exchanging heat between cooling water ...

Abstract

A heat exchanger (10), which performs heat exchange between a heat medium and air, is provided with: a tubular tube (100), the heat medium flows inside the tube; and fins (200), the fins pass through A part formed by bending a sheet metal and welded to the surface of the pipe. Louvers (210) are formed on the fins. Induction grooves (131, 132, 133) are formed on the surface (101) of the tube for inducing solder melted during soldering from a junction between the tube and the fin to other parts.

Description

[0001] Cross-reference of related applications [0002] This application claims priority based on Japanese Patent Application No. 2018-007093 filed on January 19, 2018 and Japanese Patent Application No. 2018-160828 filed on August 29, 2018, and the entire content of the patent application is referred to incorporated into this manual. technical field [0003] The invention relates to a heat exchanger for exchanging heat between a heat medium and air. Background technique [0004] As the heat exchanger for exchanging heat between the heat medium and the air, for example, a radiator for lowering the temperature of cooling water heated by an internal combustion engine, a radiator for evaporating a refrigerant in a refrigeration cycle, etc. evaporator etc. For example, as described in Patent Document 1 below, such a heat exchanger has a structure in which tubular tubes through which a heat medium such as cooling water flows and fins formed by bending metal plates are alternate...
