Embodiment

[0032] Such as figure 1 As shown, the present invention mainly includes a solution outlet 1, a generator housing 2, a steam outlet 3, a cascade disk generating tube 4, a hot water outlet 5, a solution inlet 6, and a hot water inlet 7. The cascade disc generating tube 4 is installed vertically in the generator casing 2 . The number of tube rows of the cascade disc tubes 4 and the number of tubes in each row can be changed according to the amount of actual required generation.

[0033] The core component of the present invention is the cascade disc tube 4, and its structure is as follows: figure 2 with image 3 shown. Evenly punch four circular holes with diameter slightly larger than the outer diameter of the heat pipe at the suitable circumferential position of the stainless steel pipe 10, and then extend the hot end of the folded heat pipe 9 into the stainless steel pipe 10 inside, and the cold end then stays outside the stainless steel pipe 10. Weld and fix the hot end ...

Abstract

The invention discloses a heat pipe falling film generator for low grade heat drive absorption refrigeration. The heat pipe falling film generator for low grade heat drive absorption refrigeration comprises a generator shell. A solution outlet, a solution inlet, a hot water inlet, a hot water outlet and a steam outlet are formed in the shell; step disk generation pipes are arranged in the shell, and comprise steam generation disks, heat pipes and water pipes; the water pipes communicate with the hot water inlet and the hot water outlet; the heat pipes are arranged on the water pipes in a penetrating way; the steam generation disks are fixedly connected with the heat pipes; a gap in which fallings films can be produced is remained between each steam generation disk and each water pipe. According to the heat pipe falling film generator for low grade heat drive absorption refrigeration provided by the invention, the performance of low grade heat applied in the solution generation process can be improved, the high efficient utilization of a low temperature heat source is realized, and the thermal performance of the absorption refrigeration cycle is further improved.

Description
