Reasons why the heat sink of the aluminum shell is not hot

The commonly used heat sink materials are copper and aluminum alloys, both of which have their own advantages and disadvantages. Copper has good thermal conductivity, but the price is more expensive, the processing of the radiator is more difficult, the weight is too large, the thermal constant is small, and it is easy to oxidize. Pure aluminum is too soft to be used directly. All aluminum alloys are used to provide sufficient hardness. The advantages of aluminum alloys are lower price and light weight, but the thermal conductivity is a bit worse than copper. Some radiators have their own advantages, and a copper plate is embedded on the base of the aluminum alloy radiator. So what is causing the heat sink of the aluminum shell not to be hot? The following editor, Zhong Yilong, will introduce it to you.

　　The heat sink of the aluminum shell is not hot, which may be due to the following reasons:

　　 (1) The resistance is large. In a parallel system, this problem may occur when the radiator is changed privately. The resistance is large, the hot water flow is small, and the heat dissipation is reduced;

(2) The heat medium water temperature is low, the heat dissipation is small. The standard heat dissipation commonly used by our radiators is measured at an inlet water temperature of 95°C, an outlet water temperature of 70°C, and a room temperature of 18°C. If the inlet water temperature is 70°C, the outlet water temperature At 55 ℃, the heat dissipation is about 40% lower at room temperature 18 ℃;

 　　 (3) The water pressure is low. At the far end or high place of the parallel system, the water pressure is low, the hot water is insufficient, and the heat dissipation is low;

　　 (4) The way of taking in and out water is different, and it also reduces the heat dissipation.It is best to go up and down, and enter and exit under different measurements.The radiator is about 20% lower;

　　 (5) The air is blocked, the air valve can be opened to exhaust the air in the radiator and then closed;

　　 (6) Partial blockage in the radiator;

　　 (7) There are fewer radiator fins designed or installed, and the total heat dissipation is not enough;

　　 (8) There is a heating hood, which often reduces the heat dissipation by about 20%;

　　 (9) The doors and windows are ventilated.

　　The above is the introduction of the reason why the heat sink of the aluminum shell is not hot. The aluminum shell is easy to process and has high flexibility. It is a variety of shells made of aluminum alloy. The commonly used heat sinks of aluminum shells are copper and aluminum alloys. At present, radiators mainly include heating radiators and computer radiators. Among them, radiators can be divided into several types according to materials and working modes. Computer radiators can be based on uses and installation methods. Divided into several types.
