What is the quality of Han's heat exchanger?

Personally, I feel that many products in our country are better than those abroad in terms of heat exchanger price and energy efficiency. Why do you have a crush on a foreigner? Is there a service guarantee after buying it?

The heat exchanger is very simple. Maybe I can tell you that you can do it yourself. Insert a tube into the ice and let the water in the tube flow. No matter how the ice melts, how about you keep the ice in the tube? Is it ice water presented to you? Of course, if the pipe is inserted into hot water, it must be hot water, right?

It's that simple. I don't support you to buy foreign products, and save money for us in China!

I can only remind you that when making a heat exchanger, there are calculations of temperature replacement volume and heat exchange area. In case you spend money and the effect is not good! It's also very simple!
