The first cooler unit comprises a first core part(4), a first upper tank(12) and a first lower tank(15). The first core part comprises a plurality of tubes and a heat radiation fin. The first upper tank is connected to the top of the first core part and has an inlet(23) on one of the longitudinal ends. The first lower tank is connected to the bottom of the first core part. The second cooler unit comprises a second core unit(5), a second upper tank(13), an outlet, and a second lower tank(16). The second core unit is parallel to the first core part and comprises a plurality of tubes and a heat radiation fin. The second upper tank is connected to the top of the second core unit and partly connected to the first upper tank through a first guide channel(24). The second lower tank is partly connected to the first lower tank through a second guide channel(26).
