CPU heatsink hose type heatsink, what is a heatsink?

It's not like there's nothing in the brass pipe. Half of it is pure water, and the rest is vacuumed. There is generally a large amount of copper powder on the inner wall of the copper tube.

What the book says:

Heat pipes are made up of a closed system, a tube shell, a wick, and a working fluid. Heat pipes use the physical process of phase change in working fluid to transfer heat. When the heat is transferred from the evaporation section, the working fluid in the absorbent core is heated and evaporated, and the vapor contacts the surface of the cold heat-absorbing core in the condensing section and releases heat.

The working fluid evaporates in the evaporation section, which makes the gas-liquid interface concave, forming many meniscus-shaped liquid surfaces, generating capillary indenters, sending the condensate back to the evaporation section, and completing the closed cycle. In this way, the evaporation and condensation of the working fluid continuously transfer heat from the hot end to the cold end.

From a technical point of view, the core role of heat pipes is to improve the efficiency of heat transfer and quickly remove heat from the heat source, rather than "heat dissipation" in the general sense, which includes the process of heat exchange with the outside environment. Heat pipes operate over a wide range of temperatures. From minus 200 degrees to 1000 degrees Celsius, heat pipes can be used to conduct heat.

Heat pipe heat sink The copper tube is hollow, there is no liquid in the heat pipe heat sink, the role of the heat pipe is heat conduction, the current CPU heat sink effect is generally heat pipe + fan heat sink about 100-500, or even higher, generally 100-300 is very good

The structure is described as follows:

1. The core of the segmental radiator is composed of many thin cooling pipes and heat sinks, and most of the cooling pipes adopt flat circular sections to reduce air resistance and increase the heat transfer area.

2. The tubular belt radiator is made of the auspicious pattern heat dissipation belt and the cooling pipe arranged in phases and welded by the closed pulse.

The radiator core should have enough flow area for coolant to pass through, and there should also be enough air flow area to allow enough air to pass through to take away the heat transfer from coolant to the radiator. At the same time, there must be sufficient heat dissipation area to complete the heat exchange between the coolant, air and heat sink.

This simple, tubular radiator is tubular in shape, but there are many different kinds of materials. Nowadays, most of them are made of steel and die-cast aluminum, steel-aluminum composite materials. Well done in this regard.

Steel tubular radiators are products that have been developed in recent decades. The advantages of tubular radiators are high withstand voltage and low pressure. The disadvantage is that the wall will be smoked in use, and it is afraid of oxygen corrosion, so the service life and system management have a large tube type.

This kind of radiator is not conducive to mechanized production, and the performance is not outstanding, so it is rarely used abroad. However, in China, the service life requirements are not high, so this kind of radiator is used a lot.

Steel plate radiator is currently used in foreign countries, and its advantages are high pressure resistance and low quality, which is conducive to mechanized production. The steel-aluminum composite radiators produced by Ambitburg are safe, durable, energy-saving, convenient and trustworthy.

There are many different interpretations of radiators, such as the following:

1. Radiator: air-cooled radiator.

The radiator is an important and basic component of a hot water (or steam) heating system. The hot water is cooled in the radiator (or the steam condenses in the radiator) to heat the room to achieve the purpose of heating. The metal consumption and cost of radiator occupy a considerable proportion in the heating system, therefore, the correct selection of radiator involves the economic indicators and operation effect of the system.

2. Radiator: computer radiator.

A device or instrument that transfers the heat generated by machinery or other appliances in the process of work in time to avoid affecting its normal operation. Common heat sinks can be divided into air cooling, heat pipe heat sinks, liquid cooling, semiconductor refrigeration, compressor refrigeration and other types according to the heat dissipation method.

3. Radiator: heating radiator.

The heating radiator is the terminal equipment of home heating, and the heat source is generally urban central heating, self-built boiler room in the community, household wall-hung boiler, etc., which dissipates heat through heat conduction, radiation and convection, so that the temperature of the living room can be improved. Steel radiators, aluminum radiators, copper radiators, stainless steel radiators, copper-aluminum composite radiators, steel-aluminum composite radiators, etc., as well as the original cast iron radiators.

4. Radiator: Automobile radiator.

The radiator belongs to the automobile cooling system, and the radiator in the engine water cooling system is composed of three parts: the water inlet chamber, the water outlet chamber, the main piece and the radiator core. The coolant flows inside the radiator core and air passes through the outside of the radiator core. The hot coolant cools down due to the heat dissipated to the air, and the cold air heats up by absorbing the heat emitted by the coolant, so the radiator is a heat exchanger.
