Abstract
The utility model discloses a heat exchanger for improving installation sealing performance of heat pipes. The heat exchanger comprises a cylinder, an upper end socket, an upper pipe plate, a lower end socket and a lower pipe plate. A material inlet is formed in the lower end socket, and a material outlet is formed in the upper end socket. The multiple heat pipes are arranged in the middle of the cylinder. The upper ends of the heat pipes penetrate through the upper pipe plate to be communicated with the material outlet and are in seal fit with the upper pipe plate. The lower ends of the heat pipes penetrate through the lower pipe plate to be communicated with the material inlet and are in seal fit with the lower pipe plate. A steam inlet is formed in the upper end of the cylinder, and a condensate outlet is formed in the lower end of the cylinder. The sealing performance between the heat pipes and the upper pipe plate is improved, a high-temperature medium is prevented from leaking into the upper end socket, and distilling accuracy of materials is ensured.

Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
Wherein, 1, cylindrical shell, 2, upper perforated plate, 3, lower perforated plate, 4, heat pipe, 41, protruding gear, 5, packing ring, 6, interior ring sealing ring, 7, outer shroud sealing ring, 8, regulate pad.
The specific embodiment
As shown in Figure 1, a kind of heat exchanger that improves heat pipe installation sealing, comprise cylindrical shell 1, upper cover, upper perforated plate 2, low head and lower perforated plate 3, material inlet is set on low head, material outlet is set on upper cover, the middle part of cylindrical shell 1 arranges some heat pipes 4, the upper end of heat pipe 4 through upper perforated plate 2 be communicated with material outlets and and upper perforated plate 2 between form and be sealed and matched, the lower end of heat pipe 4 is communicated with material inlet through lower perforated plate 3 and forms and be sealed and matched with lower perforated plate 3, cylindrical shell 1 upper end arranges steam inlet, and the lower end of cylindrical shell 1 arranges condensate outlet.
As shown in Figure 2, the sealing installation structure between heat pipe 4 and upper perforated plate 2 is, heat pipe 4 upper ends form protruding gear 41, and the heat pipe 4 of protruding gear 41 tops is through upper perforated plate 2 connecting bolts, and between protruding gear 41 and upper perforated plate 2, cambered surface is sealed and matched.Between bolt and upper perforated plate 2, be provided with packing ring 5, be positioned on the upper perforated plate 2 of packing ring 5 belows and be provided with sealed groove, be positioned at the adjusting pad 8 of sealing groove, regulate between pad 8 and heat pipe 4, to form spiral and coordinate interior ring sealing ring 6 and outer shroud sealing ring 7 below adjusting pad 8.Rotate and regulate pad 8 by interior ring sealing ring 6 and outer shroud sealing ring 7 bottom land that is fitted in sealed groove tightly, to avoid the phenomenon that occurs that high-temperature steam is revealed.
Sealing installation structure between heat pipe 4 and lower perforated plate 3 is that the lower end of heat pipe 4 coordinates through lower perforated plate 3 and with lower perforated plate 3 formation spirals, between heat pipe 4 and lower perforated plate 3, is provided with fluid sealant.Between heat pipe 4 lower ends and lower perforated plate 3, can form free adjustment like this, thereby can make the degree of tightness between heat pipe 4 upper end free adjustment and upper perforated plate 2, be i.e. the cambered surface of the heat pipe 4 protruding gears 41 in upper end and the distance between upper perforated plate 2.
