00:00:00,400 --> 00:00:04,366

Hello everyone, today we are going to learn about the cooling system of the laptop

2

00:00:05,100 --> 00:00:09,700

This is the radiator, it is composed of fans, copper pipe

3

00:00:12,866 --> 00:00:17,966

The CPU and GPU of a laptop almost determines its performance and positioning

4

00:00:21,533 --> 00:00:26,300

They're just tiny chips, but they generate a lot of heat when they're running

5

00:00:29,366 --> 00:00:34,866

And in the pursuit of the thin trend, laptop internal space is compressed more and more small,

6

00:00:35,366 --> 00:00:38,166

heat dissipation becomes particularly important

7

00:00:41,166 --> 00:00:44,800

If you don't have a cooling system, you'll burn out the mainboard

8

00:00:46,666 --> 00:00:50,866

Both CPU and GPU have an overheat protection mechanism

9

00:00:52,466 --> 00:00:55,600

If the temperature is too high, they will stop working,

10

00:00:55,666 --> 00:01:00,066

resulting in blue screen or death, crash, and restart,

11

00:01:00,933 --> 00:01:03,233

which affects the system performance

12

00:01:05,600 --> 00:01:07,733

In order to avoid this situation,

13

00:01:08,233 --> 00:01:13,266

the laptop manufacturer will set the corresponding "temperature wall" or "power wall"

14

00:01:13,266 --> 00:01:16,400

according to the heat dissipation ability of the computer

15

00:01:17,000 --> 00:01:23,300

In other words, the CPU or GPU performance will be limited to varying degrees to avoid overheating

16

00:01:25,266 --> 00:01:27,233

This is how it dissipates heat

17

00:01:28,433 --> 00:01:31,433

There is a temperature control circuit on the mainboard

18

00:01:31,866 --> 00:01:36,366

The temperature control circuit detects the temperature of the CPU, GPU,

19

00:01:38,400 --> 00:01:42,400

and other areas on the mainboard through the temperature control element,

20

00:01:44,433 --> 00:01:47,366

and reports the temperature to the EC in real time

21

00:01:51,600 --> 00:01:56,166

The EC adjusts the speed of the fan in real time according to the temperature

22

00:01:57,333 --> 00:02:01,900

The fan doesn't turn all the time, it doesn't turn until it gets hot

23

00:02:03,100 --> 00:02:08,033

The EC controls the fan speed to be constant or mad based on the temperature

24

00:02:08,933 --> 00:02:10,933

When the temperature reaches the limit,

25

00:02:11,633 --> 00:02:15,666

the temperature control chip will turn off the power supply to the system,

26

00:02:15,866 --> 00:02:19,100

so that the whole machine is powered off automatically

27

00:02:20,333 --> 00:02:22,666

Composition of laptop cooling system

28

00:02:23,333 --> 00:02:32,466

It is mainly composed of fan, copper pipe, heat dissipation grease, silicone pad and fan air outlet, air inlet hole

29

00:02:34,433 --> 00:02:38,866

There is a separate graphics card or CPU on the bottom of the radiator

30

00:02:41,333 --> 00:02:46,400

The contact surface between the CPU and the radiator has heat dissipation grease

31

00:02:46,966 --> 00:02:49,566

The main function of the silicone grease is to

32

00:02:49,566 --> 00:02:54,300

make the heat sink and the core of the CPU or graphics card can closely fit,

33

00:02:54,633 --> 00:02:58,500

leaving no gap, improve the heat dissipation effect

34

00:03:03,133 --> 00:03:04,366

At the same time,

35

00:03:04,833 --> 00:03:09,033

attach a thermal conductive silicone pad to the graphics card memory,

36

00:03:09,400 --> 00:03:11,733

memory or solid state disk

37

00:03:16,133 --> 00:03:22,133

The uniform heat plate of the radiator will be in contact with this conductive silicone pad,

38

00:03:22,433 --> 00:03:24,600

providing them with heat dissipation

39

00:03:30,300 --> 00:03:32,666

The fan blows at the end of the copper tube,

40

00:03:32,833 --> 00:03:35,966

and the inside of the tube is filled with condensate

41

00:03:42,133 --> 00:03:47,900

The basic working principle of condensate is to form a circular flow of condensed steam

42

00:03:53,666 --> 00:03:57,300

Quickly transfer the core temperature to the end of the copper tube

43

00:03:59,066 --> 00:04:04,333

As the fan rotates, it dissipates the heat from the ends of this copper tube

44

00:04:07,500 --> 00:04:14,166

So at the edge of the machine there will be a row of cooling holes, which are the outlet holes for the fans,

45

00:04:15,733 --> 00:04:19,866

and at the bottom of the machine there will be some inlet holes

46

00:04:21,166 --> 00:04:27,300

When we use the computer, try to ensure that the air outlet and air inlet unobstructed,

47

00:04:27,766 --> 00:04:32,600

do not be blocked, so as not to affect the heat dissipation effect

48

00:04:33,833 --> 00:04:36,700

Okay, so that's the cooling system of the laptop
