A heat insulating material 13 is provided on the outer diameter surface of the heat vibrator 12 corresponding to the compression section C to prevent heat from entering or exiting the heat pipe 12 in the compression section C. Therefore, the heat pipe 12 absorbs the heat generated in the metering section M and radiates the heat to the supply section F, which is at a low temperature, and contributes to preheating the material resin of the supply section F. Reference numeral 14 denotes an opening provided in the rear end portion 15 of the screw, which has a diameter larger than the outer diameter of the heat pipe 12, and forms a gap whose rear end surface is closed with a lid 16. The same opening 14
The end of the heat pipe 12 protrudes into the opening 14 without contacting it, and fluid such as air whose temperature has been adjusted by the temperature regulator 17 flows through the joint 18 as shown by arrows a and b. It is supposed to be done. Grooves 19 and 20 are provided in the inner diameter surface of the joint 18Fi in the circumferential direction, and holes 21 and 22 are provided for guiding fluid from the outer diameter surface, respectively. Furthermore, passages 23 and 24 communicating with the aperture 14 are provided on the outer diameter surface of the screw end 15 facing the grooves 19 and 20.

熱抵抗回路は第３図のようになる。To explain the effect of the fins 25 in detail with reference to Fig. 2, the heat that enters from point (measuring section) goes to point F, where it is split, one from point D (supply section) and the other from point D (supply section). Heat is radiated from point E (fin part). Heat input Q at point A,
Heat radiation at point D and point E is QD%q (Qn>>q)
Then, QA""Qn + Q (1) and A-
The thermal resistance between F, F-D, and F-E is R1, , R
,D, R1,, the temperature at each point is /JTA,
Assuming TDTE and T, the following formulas (2), (3) and (
4) holds, TA TF = RAF QA = RAF (QD + q) (2) Tr

TE = REFq (4) The thermal resistance circuit is as shown in Figure 3.

ＲＦＤ＋ＲＤＤ’）ＱＤ＝一定 （５）となる。Here, if we consider that the material resin at the temperature TDI is always supplied around point D (supply section), its thermal resistance RDD/
can be considered constant. Also, thermal resistance RAF t RFDRE
F is a constant physical property value except for the gas flow in the heat pipe, and if there is little variation in temperature, the gas flow resistance can be considered to be constant. Therefore, the resistance (Rrn + RDD') is constant, and if QD is constant, TF-TD'= (
RFD+RDD')QD=constant (5).

Therefore, in equation (4), the change in heat flux q is the E point source temperature T
B changes. Similarly, in equation (2), the change in A point source intensity T is a change in RA,q because F point source intensity T is constant and RFDIQD is constant, and since RAr is constant, it is a change in q. Accordingly, the temperature at point A changes TA.
