Embodiment Construction

[0029] Hereinafter, the present invention will be described in detail based on specific examples. figure 1 describes a specific example of a heat exchanger in which a first heat medium or a second heat medium flows through a plurality of narrow tubes and exchanges heat with a heat medium provided around the thin tubes. figure 1 (a) is a figure which looked at the example of the heat exchanger 1 from above. figure 1 (b) is a figure which looked at the example of the heat exchanger 1 from a lateral direction. Either the first heat medium 3 or the second heat medium 4 flows into the thin tube 2 provided in the heat exchanger 1 . In the following description, a specific example in which the first heat medium 3 flows into the thin tube will be described. The refrigerant as a heat transfer medium corresponds to the first heat medium 3 , and the refrigerant (brine) as a heat transfer medium corresponds to the second heat medium 4 .

Abstract

Provided are a heat exchanger, which is equipped with a plurality of thin tubes and base pipes on the two ends of the thin tubes thereby to make the heat exchange on the surfaces of the thin tubes, and a method for manufacturing the heat exchanger. In a heat exchanger (1), thin tubes (2) for flowing a second heat medium (4) are held in close contact with the insides of tubular base pipes (5), andthe thin tubes (2) are disposed in a first heat medium (3), so that the second heat medium (4) and the first heat medium (3) exchange their heats. The heat exchanger (1) is characterized in that the internal diameter of the base pipes (5) are enlarged on the sides, to which the thin tubes (2) are attached.

Description

technical field [0001] The present invention relates to a heat exchanger for exchanging heat between a high-temperature heat medium and a low-temperature heat medium. In addition, it relates to a heat exchanger and a method for manufacturing the heat exchanger, which perform heat exchange through partition walls by flowing a high-temperature heat medium or a low-temperature heat medium into a plurality of thin tubes. Background technique [0002] At present, when heat is exchanged between a heat exchanger or a heat medium of a heat exchanger and a regenerator, from the viewpoint of the heat transfer efficiency between the heat medium, it is known that a plurality of tubes are arranged inside the heat storage material. structure. One of these cases is described in Japanese Patent Application Laid-Open No. 2005-233597. In the thermal storage heat exchanger described in this Japanese Patent Application Laid-Open No. 2005-233597, a plurality of tubes through which a heat mediu...
