Q:How many kilos are there in one of the 6 copper tubes?
The wall thickness of 0.5mm copper tube, the theoretical weight per meter is 0.077kg;The wall thickness of 0.75mm copper tube, the theoretical weight per meter is 0.110kg;
Q:How do you handle the ice on the back of the freezer?
The freezer behind the tube temperature is very low, less than 0 degrees.
Q:In the process of using outdoor air conditioning machine after the copper frost is going on,
Like Freon enough or valve not completely open, this season there is a little frost outside may also be normal, the environment is relatively cold
Q:In the orchestra, which is a stringed musical instrument? What are the woodwinds? What are the brass?
The main stringed instruments in the symphony include the violin, Viola, cello, bass and bass,A woodwind, flute, piccolo, clarinet, Oboe, bassoon,Brass, horn, trumpet, trombone, tuba
Q:Heat dissipation principle of main copper tube 50
The heat in the liquid will be transferred, and the exposed copper tube will give off the heat of the liquid, and the liquid will also act so as to release the heat.
Q:Excuse me, brass, stainless steel, aluminum, how many were the thermal conductivity of carbon steel tubes urgently?!
Stainless steel heat conduction coefficient from big to small in the order of 1Cr17, 00Cr12, 25N, Cr 2 Cr 0 18Ni11Ti, 0 Cr 18 Ni 9, 0 Cr 17 Ni / 12M 2, Cr 225Ni20.500 C heat conduction coefficient from big to small order of 1 Cr 13, 1 Cr 17, 2 Cr 25N, 0 Cr, 2 17Ni12M / 0 Cr 18Ni9Ti and 2 Cr 25Ni20. austenitic stainless steel thermal conductivity is slightly lower than other stainless steel, and compared to ordinary carbon steel, at 100 degrees, austenitic stainless steel thermal conductivity of about 1/4C. aluminium tube
Q:Is there anything in the copper tube of the CPU radiator?
The heat pipe contains heat conduction liquid, so that the heat can be transmitted to the radiator rapidly, and some radiators are a principle!
Q:The length of the copper pipe between the indoor air conditioner and the outdoor host is suitable.
Generally speaking, 3M standard configuration, the longest not more than 10M, but the effect is worse, in the middle of cold consumption, in fact, you can add more cold media can also. It just depends.
Q:Air conditioning copper tube can hold several meters longest
Different types and different sizes of air conditioners can connect different lengths of copper tubes.
Q:The 3P air tube is generally what specifications please enlighten!
This is not necessarily, there are 6 and 16,10 and 16, frequency conversion, there are 6 and 12.
