Example 2, tube cavity diameter are 6mm, and total length 2.5m, fluid is non-methane total hydrocarbons (NMHC), is passed using first The temperature of the fluid of sensor measurement is 100 DEG C, optionally, in 2 filled layer of phase-change heat-storage material, the molecule of paraffin main component Formula is C₃₀H₆₂, mass fraction 23.7%, metal alloy use Bi (56%)-Sn (40%)-Zn (4%) compound, account for 68.3%, graphite additive amount accounts for 8%.

The mode of being rapidly heated when with 130 DEG C of set temperature is illustrated, and control circuit driving heating component carries out first Heating, when fluid reaches transformation temperature (130 DEG C) temperature of phase-change heat-storage material, phase transformation to the first temperature sensor measurement into pipeline Heat accumulating starts to absorb the heat that heating component distributes, and the heat for receiving fluid greatly reduces；It is passed according to second temperature The temperature of sensor acquisition and the temperature of the first temperature sensor acquisition, FUZZY ALGORITHMS FOR CONTROL is triggered later, according to PID controller Initial value (actual temperature/set temperature: 120 DEG C/130 DEG C) obtain corresponding regulated value (for example, heating power be 73W), so It is added afterwards and obtains final pid control parameter (for example, exporting heating power 74W, and with the decrease of speed of 0.25W/s), thus Keep the temperature that can control fluid in tube cavity near element heating power parameter fast approaching target thermal equilibrium value constant 130 DEG C ± 0.05 DEG C, improve temperature controlled precision.

Wherein, it should be noted that for heating, cooling of other fluids under accurate temperature controlling mode, and quickly control Heating, cooling under warm mode can refer to the relevant portion of above-described embodiment, and details are not described herein by the application.

The foregoing is merely preferred embodiment of the present application, are not intended to limit this application, for the skill of this field For art personnel, various changes and changes are possible in this application.Within the spirit and principles of this application, made any to repair Change, equivalent replacement, improvement etc., should be included within the scope of protection of this application.
