Example 1

Referring to fig. 1 to 3, the jacketed condenser of the present embodiment includes a first casing 1, a second casing 2 disposed outside the first casing 1, a jacket 3 formed between the first casing 1 and the second casing 2, a plurality of air inlets 11 disposed at the bottom of the first casing 1, and a plurality of vertical condensation pipes 12 disposed in the first casing 1. Through set up the cover 3 that presss from both sides between first casing 1 and second casing 2, make steam at first get into and press from both sides cover 3, because the outer wall of first casing 1 is more end under the effect of condenser pipe 11 in first casing 1, steam is through pressing from both sides the cover, get into first casing 1 inside once more, through the condenser pipe, the time that the steam flowed through the condenser pipe has been prolonged, just so make steam molecule can the cooling reflux, prevent to inhale the diffusion pump in a large number, influence diffusion pump work efficiency, thereby improve the vacuum of evaporimeter. Meanwhile, compared with the original coil type condenser pipe, the hollow structure in the middle of the coil pipe causes part of vapor molecules to be rapidly drawn away from the hollow part and not to be fully cooled. In the embodiment, a plurality of air inlet holes 11 and the condensing pipe 12 are used to form a honeycomb structure, so that the cooling efficiency is improved.

More specifically, a condensation structure 4 is arranged in the first casing 1, the condensation structure 4 comprises an air inlet 11 and a condensation pipe 12, and a certain gap structure is formed between the condensation structure 4 and the first casing 1. The gap structure helps the vapor to diffuse into the air inlet holes.

In the present embodiment, the air inlets 11 and the condenser pipes 12 are arranged in a staggered manner, as shown in fig. 1, the vapor enters the plurality of condenser pipes 12 arranged in the first housing through the plurality of air inlets 11, the vapor flow is dispersed due to the density of the plurality of air inlets 11, the vapor channel 13 formed by the gaps between the plurality of condenser pipes can exchange heat with the condenser pipes 12 sufficiently, and part of vapor molecules are cooled and then flow back.

According to another embodiment, the condenser tube 12 is provided as a jacketed condenser tube, the hollow passage enclosed by the inner wall of the condenser tube forming the vapor passage 13.
