As preferably, each ring light sliding surface being equipped with several staggered projections. Each projection can add strong disturbance effect further.
As preferably, copper pipe inwall being provided with several SMD temperature sensors of axially spaced distribution. Temperature sensor is for detecting the temperature of copper pipe, such that it is able to the interpolation of the change control condensing agent according to copper pipe temperature.
As preferably, the cross section of each groove is all trapezoidal.
Therefore, this utility model has the advantages that the resistance effectively reducing condensing agent circulation, improves the exchange rate between different parts condensing agent in copper pipe.
