Fig. 1 is a kind of schematic diagram that is used for the condenser system of freeze dryer of the utility model;
Fig. 2 is the vertical view (removing plate shell top board) of the triple heat exchanger plates of condensation body of a kind of condenser system that is used for freeze dryer of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model implementation column is elaborated.
See also Fig. 1, Fig. 2, the utility model, it is a kind of condenser system that is used for freeze dryer, comprise condensation body 1, pass through freeze drying box 3, main valve 6, electric heater 7, first circulating pump 8, second circulating pump 9, vavuum pump 10, refrigeration compressor 11, first circulation valve 12, second circulation valve 13 and refrigeration by-pass valve control 14 that vacuum pipe 5 is connected with this condensation body 1, wherein, freeze drying box 3 inside are provided with some flaggies 4; In the vacuum pipe 5 of main valve 6 between freeze drying box 3 and condensation body 1.
Condensation body 1 comprises the shell (not shown) and is the some piece triple heat exchanger plates 2 of fan-shaped array in this enclosure, each triple heat exchanger plate 2 comprises the plate shell 21 of tetragonal body, copper pipe 22 and some ribs 23, the length of rib 23 is less than the length of plate shell 21 inner chambers, on these several ribs 23, the lower surface is fixedly connected on respectively on the end face and bottom surface of plate shell 21, these several ribs 23 are consistent at interval with front and back at plate shell 21 inner chambers, and the staggered respectively mode that leans on the left and right side of plate shell 21 in a side is arranged, and makes these plate shell 21 inner chambers form a maze-type structure; Insert front portion outside copper pipe 22 slave plate shells 21 1 sides, and complications coiling round in the neutral of the interval of adjacent rib 23 neutral gear and rib 23 sides and plate shell 21 left and right sides successively, and the rear portion, a side of slave plate shell 21 passes, and the spacing distance of adjacent rib 23 is greater than the diameter of copper pipe 22; The cold-producing medium (freon) that provides by refrigeration compressor 11 is provided in the copper pipe 22, is filled with conduction oil (silicone oil) in the gap of copper pipe 22 and plate shell 21.
