A heat exchanger module includes a condenser unit and an evaporator unit. The evaporator unit includes N pieces of parallel-flow heat exchangers arranged adjacently, and the coolant temperatures reduce gradually from the first to Nth parallel-flow heat exchangers along an air flow direction in the evaporator unit. A counter-current mounting method is adopted in the parallel-flow heat exchangers of the evaporator unit in the heat exchanger module provided by the present invention. The coolant temperature of each parallel-flow heat exchanger is lower than that of the previous one, the temperature difference between air and coolant is relatively uniform by using the counter-current method so as to reach a better heat exchange effect.

In one aspect, a cooling system is provided for use in computing devices, such as laptops, cell phones, and tablet computers. The cooling system includes a heat spreader coupled to a radiator via a heat pipe having a midline. The heat pipe includes a first end portion longitudinally extending along the midline, a second end portion longitudinally extending along the midline, and a mid-portion longitudinally extending along the midline. The mid-portion is located between the first end portion and the second end portion and it has a thickness that is greater than the thicknesses of both the first portion and the second portion thereby reducing the overall thermal resistance of the heat pipe.
