我就想不明白了，CPU空间小装不了大散热器用循环水情有可原，这半导体制冷片又没空间限制，
水冷散热器所需的用具非常庞大，占用了一定的空间。 - wikipedia 来源
The advantages of using water cooling over air cooling include water's higher specific heat capacity, density, and thermal conductivity. This allows water to transmit heat over greater distances with much less volumetric flow and reduced temperature difference. - wikipedia 来源
wikipedia中明确指出 water's higher specific heat capacity, density, and thermal conductivity.
另外，通过水来传递热能，符合wikipedia上的水冷定义：
Water cooling is a method of heat removal from components. As opposed to air cooling, water is used as the heat transmitter.
明显不是“只有风冷”
无非就是加大了点散热面积而已。
上述材料已经明确指出了使用水冷的好处
根据你的理论 我实在想不通为何坦克的CPU要使用半导体制冷+循环水冷
第二次根据你的理论，核电站最终也是将热量排放到空气中，不知道算什么冷？
