During the use of the condenser, depending on the stability of the external environment, in hot summer, the infusion pump 7 is started, and the infusion pump 7 injects coolant into the interior of the condenser shell 2 for filling, which can keep the temperature of the condenser stable, so that the condenser as a whole does not depend on the ambient temperature and the ambient temperature can be manually changed.

[0027] Example 2

[0028] like Figure 1-4 As shown, a condenser for pharmaceutical intermediate production according to an embodiment of the present invention includes a mounting back plate 1 and a condenser shell 2.

[0029] Example 3

[0030] like Figure 1-4As shown, a condenser for producing pharmaceutical intermediates according to an embodiment of the present invention includes a mounting back plate 1 and a condenser housing 2. The rear side of the condenser housing 2 is fixedly connected to the mounting back plate 1. An inlet pipe 3 is provided on the upper left side of the condenser housing 2, and an outlet pipe 4 is provided on the lower left side. A front cover plate 5 is connected to the front side of the condenser housing 2. A ventilation housing 6 is movably embedded in the front side of the front cover plate 5. First threaded posts 15 movably pass through the four corners of the front side of the front cover plate 5. The rear ends of the first threaded posts 15 are fixedly connected to the four corners of the front side of the condenser housing 2. The first threaded post 15 has a matching threaded connection to the outer wall of the first nut 16. The ventilation housing 6 includes a connecting frame 17 and a mounting box 18. The rear side of the outer wall of the mounting box 18 is fixedly connected to the interior of the connecting frame 17. An exhaust fan 19 is provided at equal intervals on the front side of the mounting box 18. The rear side of the mounting box 18 is movably embedded in the mounting groove 10 and covers the outside of the second heat dissipation fins 11. The four corners on the front side of the connecting frame 17 are respectively fixedly connected to the second threaded post 20. The second threaded post 20 is connected to the four corners on the rear side of the inner wall of the mounting groove 10.

The first heat dissipation fin 9 and the second heat dissipation fin 11 are both engaged with the outer wall of the serpentine infusion tube 8 through the semi-circular groove 14. The second heat dissipation fin 11 passes through the opening 13 on the front side of the sealing baffle 12, so that the first heat dissipation fin 9 and the second heat dissipation fin 11 are assembled in a modular form, and the sealing baffle 12 seals the cooling medium injected into the interior of the condenser shell 2. The front cover plate 5 is sleeved on the first threaded post 1. 5. On the outside, then tighten the first nut 16 to install and fix the front cover plate 5 to the front side of the condenser housing 2. The connecting frame 17 is sleeved on the second threaded post 20 on the rear side of the inner wall of the mounting groove 10 on the front side of the front cover plate 5. Then, rotate the second nut 21 to embed and fix the mounting box 18 in the mounting groove 10 on the front side of the front cover plate 5. This allows for quick disassembly of the condenser housing 2 and the ventilation housing 6 from the front cover plate 5, thereby allowing the first heat dissipation fin 9 and the second heat dissipation fin 11 to be separated front and back. This exposes most of the serpentine infusion tube 8 to the environment, effectively preventing particulate matter or high-viscosity gas from clogging the narrow fin gaps, and enabling fine cleaning.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
