<p>[Problem] To simplify the configuration of heat exchange plates, facilitate production, and enhance versatility in a battery heat exchanger comprising a plurality of heat exchange plates. [Solution] A battery heat exchanger (3) having at least two heat exchange plates (4) arranged so as to sandwich a battery cell (2), wherein the heat exchanger is characterized in that: each of the heat exchange plates includes a first metal plate (16) in which a first through-hole (31) and a second through-hole (32) are formed, and a second metal plate (17) in which a third through-hole (33) and a fourth through-hole (34) are formed; a peripheral part of the first metal plate and the second metal plate is sealed; a first tube (41), second tube (42), third tube (43), and fourth tube (44) made of resin are formed by molding at a hole edge of the first, second, third, and fourth through-holes; the first and third tubes are formed to a size enabling the same to fit with each other so as to be displaceable in the axial direction; and the second and fourth tubes are formed to a size enabling same to fit with each other so as to be displaceable in the axial direction.</p> |
