an inner housing through which the first liquid circulates, and
a pair of first plate-like members attached to the inner housing so as to be opposed to each other,
each of the pair of outer members is provided with
an outer housing through which the second liquid circulates, and
a second plate-like member attached to the outer housing, and
the pair of outer members are disposed at positions across the inner member from each other so that one of the pair of first plate-like members is opposed to one of the second plate-like members of the pair of outer members, and the other of the pair of first plate-like members is opposed to the other of the second plate-like members.

2 . The heat exchange device according to claim 1 , wherein
each of the pair of first plate-like members is provided with a heat receiving member disposed in the inner housing, and adapted to receive heat from the first liquid, each of the second plate-like members is provided with a heat release member disposed in the outer housing, and adapted to release conducted heat to the second liquid, the one of the pair of first plate-like members and the one of the second plate-like members are connected to each other so as to be able to conduct the heat, and the other of the pair of first plate-like members and the other of the second plate-like members are connected to each other so as to be able to conduct the heat.

3 . The heat exchange device according to claim 1 , wherein
the inner housing has a division wall adapted to divide an inner space of the inner housing into a first space as a space of one of the pair of first plate-like members, and a second space as a space of the other of the pair of first plate-like members, and the first liquid having circulated in the first space is made to flow into the second space.

4 . The heat exchange device according to claim 3 , wherein
the division wall has a communication opening adapted to communicate the first space and the second space with each other.

5 . The heat exchange device according to claim 4 , wherein
the division wall is formed along a vertical direction, and the communication opening is located in a vicinity of an end portion on an upper side in the vertical direction in the division wall.

6 . The heat exchange device according to claim 5 , wherein
among the pair of first plate-like members,
the first plate-like member located on the first space side is connected to the second plate-like member of the outer member located on a downstream side in a flow channel of the second liquid out of the two outer members so as to be able to conduct the heat, and
the first plate-like member located on the second space side is connected to the second plate-like member of the outer member located on an upstream side in the flow channel of the second liquid out of the two outer members so as to be able to conduct the heat.

7 . The heat exchange device according to claim 1 , wherein
the inner housing is provided with
an inner-housing-side inlet through which the first liquid flows into the inner housing, and
an inner-housing-side outlet through which the first liquid located inside the inner housing flows to an outside, and
the inner-housing-side inlet and the inner-housing-side outlet are located in a surface on the same side of the inner housing.

8 . The heat exchange device according to claim 7 , wherein
the inner-housing-side inlet is located on a lower side in a vertical direction, and the inner-housing-side outlet is located on an upper side in the vertical direction.

9 . The heat exchange device according to claim 1 , wherein
each of the outer housings is provided with
an outer-housing-side inlet through which the second liquid flows into the outer housing, and
an outer-housing-side outlet through which the second liquid located inside the outer housing flows to an outside, and
the outer-housing-side outlet provided to the one of the two outer members and the outer-housing-side inlet provided to the other of the two outer members are connected to each other so that the second liquid can circulate.

10 . The heat exchange device according to claim 9 , wherein
the outer-housing-side outlet provided to the one of the outer members and the outer-housing-side inlet provided to the other of the outer members are located in surfaces facing to the same side, the outer-housing-side inlet provided to the one of the outer members and the outer-housing-side outlet provided to the other of the outer members are located in surfaces facing to the same side, the outer-housing-side inlet provided to each of the two outer members is located on a lower side in a vertical direction, and the outer-housing-side outlet provided to each of the two outer members is located on an upper side in the vertical direction.

11 . The heat exchange device according to claim 1 , further comprising:
a thermoelectric conversion element disposed in at least one of a position between the one of the first plate-like members and the one of the second plate-like members and a position between the other of the first plate-like members and the other of the second plate-like members, wherein a heat absorbing side of the thermoelectric conversion element faces to the first plate-like member, and a heat release side of the thermoelectric conversion element faces to the second plate-like member.

12 . A cooling device comprising:
the heat exchange device according to claim 1 ; a heat absorbing device adapted to absorb heat generated in a cooling object to conduct the heat to the first liquid; and a heat radiation device adapted to radiate heat of the second liquid to which the heat is conducted from the first liquid in the heat exchange device.
