  The blade fins used in the above-described cooling device generally require the use of precise machine tools because they form fins on a thick substrate by cutting or the like, compared to pressing or the like. It's not easy. For this reason, the number of assembling steps of the cooling device is increased. The corrugated fins are relatively easy because they can be formed by bending a thin plate by press processing, but they are easily deformed because they are formed of a thin plate, and attachment to a heat dissipation substrate becomes difficult.

  The fin member and the temperature control device of the present invention have a main object to provide a fin member which is not easily deformed with a relatively simple configuration and a temperature control device including such a fin member. Moreover, the method of manufacturing the fin member and the method of manufacturing the temperature control device according to the present invention mainly aims to relatively easily manufacture the fin member which is not easily deformed with a relatively simple configuration and the temperature control device including such fin member.

For brazing, the contact surface between the heat dissipation substrate 28 and the fin member 30, the contact surface between the bottom of the case 22 and the fin member 30, and the engaging portions 33 of the plurality of plate members 31 constituting the fin member 30, The contact portion between 36 and the engaged portions 37 and 34 is performed.

  Next, how the heat generated by the inverters 14a and 14b is dissipated by the heat sink 20 of the embodiment will be described. The heat of the inverters 14 a and 14 b is transmitted to the heat dissipation substrate 28 through the circuit board 12 and further to the fin member 30 joined to the heat dissipation substrate 28. The cooled heat exchange medium is supplied to the inlet 23 formed in the case 22 of the heat sink 20, and the heat exchange medium is supplied from the inlet 23 to the fin member 30 via the inlet manifold 24. In the fin member 30, a central rectangular flow passage formed when the engaging portions 33 and 36 and the engaged portions 37 and 34 are engaged in an annular shape, and the adjacent plate-like members 31 communicating therewith are communicated. Since the heat exchange medium flows through these flow paths formed in the fin member 30, it is mainly heated by the heat from the fin main body 38, and the outflow side manifold 25 and out the outlet 26. Thus, the heat generated by the inverters 14a and 14b is continuously released to the heat exchange medium through the fin member 30.

The engagement between the projections 33b, 36a, 36b and the projections 37b, 37a, 34b, 34a can suppress the displacement, and the fin member 30 can be made more difficult to deform.

  Further, since the engaging portions 33 and 36 and the engaged portions 37 and 34 are annularly engaged, the central rectangular hole formed at that time can be used as the flow path of the heat exchange medium. Furthermore, by forming the fin main body 38 of the plate-like member 31 so as to bend a plurality of times at regular intervals, a flow path of a heat exchange medium which bends a plurality of times can be obtained. As a result, the flow path length of the heat exchange medium becomes long, and the heat radiation effect can be increased.
