Maintenance Items For Various Types Of Custom Heat Sinks

At present, there are many types of custom heat sinks. For example, they are different from different profiles to different functions. Therefore, the maintenance strategies for different custom heat sinks may be slightly different when they are used. Let me introduce you today. The main points are the maintenance precautions of various types of custom heat sinks.

1. Custom heat sink made of steel: The custom heat sink made of steel requires that the PH value of the system water quality is greater than 7 and less than 12, and it must be matched with the heating system of the community. Consumers who use open heating systems for heating should be cautious in choosing steel Custom heat sink, because steel custom heat sink is prone to oxidation and corrosion in the presence of oxygen, it has strict requirements on the oxygen content of open boilers and water, all of which must be maintained in the main system after the heating season, otherwise the custom heat sink will be corroded. Water leakage problem.

2. Copper-aluminum composite heat sink: The custom heat sink of copper-aluminum material does not limit the PH value of the system water quality and the district heating system, because its internal copper structure has good oxidation resistance, and its exterior is aluminum fins. The fins dissipate heat, so the heat dissipation effect is better.

3. Copper-aluminum composite finned tube radiator: Do not open and close the valve of the radiator at will, do not open the valve to take the water in the radiator, so as not to affect the heating effect of the radiator. When the steel-aluminum composite radiator is not used, try to perform full water maintenance to increase the service life of the radiator.

4. Extruded aluminum heatsink: wrap the aluminum heatsink extrusion with a cover. After the aluminum profile radiator is wrapped, it will form a sanitary dead corner in its cover, breeding bacteria and pests and easy to accumulate dust. When heating again, dust and Bacteria will fly all over the house due to air convection. The environment inside the house is not good. Bacteria will be inhaled into the body and pose a hazard to human health. It will also cause problems such as deformation of the heating radiator cover and inconvenient maintenance.

5. LED custom heat sink: Ordinary LED lamps should be used in a humid environment. The humid environment will affect the electronic components of the LED lamp driving power supply. If the relevant electronic components on the led heat sink get damp, the lamp life will be greatly shortened. .

6. Electric vehicle liquid cold heat sink: Electric vehicle heat sink is an important component in the automotive water-cooled engine cooling system. At present, it is developing in a light and economical direction. Automobile heat sinks are also constantly adapting to new developments. The structure of electric vehicle liquid cold plate heat sink can be divided into two types: DC type and cross flow type.

The core structure of the heat sink of an electric vehicle has two types: tube-slice type and tube-band type. The core of the tube-fin heat sink consists of many thin cooling tubes and fins. The cooling tube adopts an oblate cross-section to reduce air resistance and increase heat transfer area.

The core of the custom heat sink should have a certain flow area for the coolant to pass through, and it should also have a sufficient area for the air to flow through, so as to take away the heat from the coolant to the radiator. It must also have a certain heat dissipation area, so that the heat exchange between the coolant, air and the heat sink can be completed.
