Advantages and disadvantages of metal body and plastic of TV

At present, the shells used in TV boxes on the market can basically be divided into two categories: metal and non-metal.

Generally speaking, the non-metallic shell is made of ABS PC plastic, which has the characteristics of low ignition point and high temperature resistance, and the shell is not easy to melt or burn when the inside of the set-top box is high for a long time, which is very helpful for daily use.

When two products are in the same volume, the metal contains free electrons.

It can flow freely in the metal, and when heated, the flow of free electrons will quickly transfer the energy to the whole metal, which is manifested by fast heat transfer, while the plastic has fewer free electrons, and the flow of energy in the object is slower. So free electrons are the key to heat transfer.

Therefore, although metal set-top boxes are hotter to the touch than plastic ones (this is because they conduct heat from the inside to the outside, that is, to the outer shell of the set-top box, so metal is hotter to the touch); Plastic, on the other hand, keeps the heat on the inside, and it's hot on the inside, but it feels normal on the outside. But this is only the most rough judgment, because although some boxes are plastic shells, there may be a structure of the shell or internal heat dissipation considerations, so it is not possible to generalize.

If the efficiency is higher in the conversion process, the less power loss, the less heat, when the internal overheating, the temperature continues to be too high will accelerate the aging of the components, and eventually lead to the short life of the set-top box, the system components are overloaded and crash.

The external factor that affects the temperature of the set-top box body is its shell, due to the difference in thermal conductivity of metal and non-metal materials, the impact on the heat dissipation of the fuselage is also relatively large.

The appearance competitiveness of the set-top box is achieved by the shell, so this is also the reason why many manufacturers are willing to set up a special design team for the shell, and the material of the shell also directly determines the feel and heat dissipation performance, which can enhance the overall competitiveness of the product.

Too high a body temperature will accelerate the internal electronics.

Aging, optimizing the internal structure of the set-top box can improve heat dissipation, and the shell material also has a great impact on heat dissipation, which are the two aspects that an excellent set-top box needs to have. When everyone is using the TV box, they are heating up on the fuselage.

There is no need to panic, and the set-top box should not be placed in a high-temperature environment for a long time.

Or in an environment that is not conducive to heat dissipation, fully do a good job of heat dissipation measures, you can fundamentally avoid the box crash, system crash, and prolong the life of the set-top box.

Of course, the set-top box crash and system crash may also be caused by the instability of the system itself or the existence of too much junk software in the system, and the system running space is insufficient to operate normally

1. Brush the machine to solve the problem once and for all!

Search on the ZNDSSsmart TV network to find the firmware suitable for your box model,Brush it into a stable system according to the flashing method,Then install dangbei market,Watch live TV live through the best TV software in dangbei market。

However, flashing is risky and requires operation.

The cost of metal is very high, the weight is heavier, the cost of transportation and packaging is rising, and in addition, the metal body will have rust due to changes in temperature and humidity in use, etc., but the plastic body is lower in terms of material cost, and the cost of transportation and packaging is also low, and it is related to heat resistance and heat dissipation, etc., but the time of the plastic factory will also have faded and aging changes due to the relationship between temperature and humidity. This is a matter of personal preference.

The LCD flat screen itself already has a metal backplate. As for the TV backplane, it's just a shell, and what backplane is used has no effect on the TV picture. It's just that the appearance feels different, in fact, the TV is placed at home, and no one cares about the back panel of the TV.

Pick TV,There is no need to choose a backplane,Focus on picture quality、Technical indicators such as functions。

First of all, let me explain,LCD TV backplate and shell are two different things! It's not one, and that's important. Because it directly depends on the use of your TV after you buy it.

First, if the LCD but the back panel is metal, then it means that you can use a wall mount to hang the TV on the wall, if it is plastic, then you have to ask.
