る。(Example) In FIGS. 1 and 2 showing an example, the same reference numerals as those in FIG. 5 indicate corresponding parts. In Fig. 1, the deflector plate 2
1, the side projecting portion 21a toward the cooled fluid inlet 18 and outlet 19 side (upper side in FIG. 1) is made of a shape memory alloy, and the temperature of the cooled fluid flowing in from the inlet 18 is a predetermined value. When it becomes below, it bends from the state shown by the chain line to the state shown by the solid line, thereby forming a short-circuit passage 22 from the inlet 18 to the outlet 19. As shown in FIG. 2, the main body of the deflecting plate 21 can be formed of a side projecting portion 21a and another conventional steel plate, and the deflecting plate 21 made of iron plate has a half-moon shaped side made of a shape memory alloy plate. The side projecting portion 21a is fixed by screwing, riveting, spot welding, or the like. In this way, the amount of shape memory alloy used can be minimized.

が防止されるのである。If the temperature of the fluid to be cooled is high, the fluid to be cooled enters the inlet 18.
It passes through a meandering cooled fluid passage 17 and is discharged from an outlet 19, during which time it is cooled by a cooling pipe 9. When the temperature of the fluid to be cooled is below a predetermined value, the side projecting portion 21a of the baffle plate 21 is bent as shown by the solid line in FIG. It reaches the outlet 1.9 directly via the short-circuit passage 22 and is hardly affected by the cooling effect of the cooling pipe 19. That is, the shape of the baffle plate 21 is such that when the temperature of the fluid to be cooled falls below a predetermined temperature, the forced meandering passage (passage 17) for the fluid to be cooled is cut, and a short circuit passage 22 from the inlet 18 to the outlet 19 is formed. changes, which causes the supercooling of the fluid to be cooled II
is prevented.

確実なため、長期間安定に作動する利点がある。(Effects of the Invention) As explained above, according to the present invention, at least the side projecting portion 21a of the baffle plate 21 is made of a shape memory alloy, so that when the temperature of the fluid to be cooled is high, the fluid can flow inside the heat exchanger element. If the temperature of the fluid to be cooled is lower than a predetermined value, the fluid flows through the element through the inlet 18.
Flows from the source toward the outlet 19 in a short circuit. Thereby, it is possible to prevent overcooling of the fluid to be cooled without providing a thermostat or a bypass passage, and by keeping most of the shape of the conventional heat exchanger as it is. Therefore, the cost of the entire system is reduced, and since the baffle plate made of shape memory alloy operates reliably, it has the advantage of stable operation over a long period of time.

In order to make the lengths 2 and 2 as short as possible, it is preferable that they be on the same plane as shown in FIG. Further, in the present invention, the same effect can be obtained even when the baffle plate 21 is somewhat inclined (approximately perpendicular) to the cooling pipe 9. That is, "orthogonal" in the present invention is used to include the case of substantially orthogonal.
