Problems solved by technology

[0007] However, in the core structure of the conventional heat exchanger, when the refrigerant flows from the engine into the radiator, as described below, the temperature changes rapidly from low to high, and the tube 102 and the seat plate 101 undergo a large thermal expansion, which can make the connection Section 106 compresses tube 102, causing the root of tube 102 to fracture and / or destroy

Embodiment Construction

[0033] Embodiments of the heat exchanger core structure of the present invention will be described below.

[0034] Incidentally, in these embodiments, application of the heat exchanger to an automatic radiator having flat tubes will be described.

[0035] as figure 1 As shown, the heat exchanger core structure of the first embodiment of the present invention includes a main body portion of a radiator 1 and a pair of seat plates 2 disposed at the top and bottom opposite to each other.

[0036] Reinforcing members 5 are arranged on the two side ends 2a of the seat plate 2 respectively and connect the seat plate 2 at the top and the bottom. Between the seat plate 2 and the stiffener 5, in the width direction of the radiator 1, the tubes and the corrugated vanes 4 are arranged alternately at predetermined intervals therebetween.

[0037] In the tubes 3 a coolant flows, which coolant acts as a heat exchange medium according to the invention.

[0038] as Figure 2-4 As shown, o...

Abstract

In a core structure of a heat exchanger, tubes (3) and corrugated fins are alternately arranged between seat plates (2) arranged opposite to each other with a predetermined space interposed therebetween. End portions (3c) of the tubes (3) are inserted into tube holes (2b) formed respectively in each of the top and bottom seat plates (2) to be fixed. On the seat plates (2), there are provided connection portions (2c) having wall portions (2f) slanting from main body portions (2h) thereof toward the tubes (3). When a thickness of the tubes (3) is 0.13 mm to 0.23 mm, a slant angle ¸ of the wall portions (2f) of the connection portions (2c) is set to satisfy: slant angle ¸ (°) ‰¥ 25 × (thickness (mm) of sheet plate) + (-125 × (thickness (mm) of tube) + 25).

Description

technical field [0001] The present invention relates to a core structure of a heat exchanger having tubes through which a heat exchanging medium flows, the tubes being fixed to a seat plate, corrugated vanes radiating heat of the heat exchanging medium passing through the tubes. The invention relates in particular to a core structure for use as a heat exchanger, eg on a car or the like. Background technique [0002] The core structure of a conventional heat exchanger is disclosed in Japanese Patent Laid-Open No. Tokkaihei 11-14285 and Japanese Patent Laid-Open No. Tokkaihei 9-318292 as examples. The core structure of these conventional heat exchangers has a structure in which both side end portions of the seat plates arranged to face each other are connected with reinforcing members. [0003] Figure 10 An example of such a conventional heat exchanger core structure is shown, in which tubes 102 and corrugated vanes 103 are alternately arranged between seat plates 101 facing...
