The outer tube is typically provided with an upper and a lower opening on both sides, which is followed by a plastic tube carrying a cooling substance, typically water. In use, the lower opening of the outer tube is typically docked to a faucet, allowing water to flow from below to above for maximum cooling. However, the existing condensation reflux device has the defects that water is required to be continuously and not recycled, and a test person is required to take duty in the test process to prevent the condition of unexpected interruption of cooling water or accidents such as leakage and water pipe falling caused by unstable water pressure. In addition, the strict test process needs to ensure that the steam loss is reduced as much as possible under the condition that the contained liquid does not overflow. The condensing reflux device is an open device, and it is difficult to ensure that no steam is lost.
The patent publication No. CN203605746U provides a condenser tube for solving the problem of poor condensing effect of the existing condenser tube. The condensing tube comprises a tube body and a sleeve sleeved outside the tube body, wherein an upper connector and a lower connector are arranged at two ends of the tube body, a water inlet and a water outlet are arranged on the sleeve, a regular triangular prism-shaped water pipe channel is arranged inside the tube body, and two ends of the regular triangular prism-shaped water pipe channel are sealed. The structure of the pipe body is improved, so that the contact area between the object to be collected in the steam state and cooling water in the pipe body is increased, and the cooling efficiency and the working efficiency are improved.
The Chinese patent grant publication No. CN104307585B provides a condensing reflux device which consists of a condensing outer pipe and a condensing inner pipe; the condensing inner tube is arranged in the condensing outer tube, and a cooling water cavity for storing cooling water is formed between the condensing inner tube and the condensing inner tube, so that steam and the cooling water exchange heat and then are condensed and reflowed. The condensing inner tube is a straight tube or a convergent tube or a spiral tube. The inner and outer closing connecting pieces are lacing wires which are connected with the inner and outer condensation pipes, and the number of the lacing wires is more than or equal to 2; or the circular plate is connected with the inner and outer condensing pipes, and is provided with a hole for discharging the cooling water after the steam flows out and the test is finished. The above patents require uninterrupted and non-circulating water or water supply without continuous flow, but none address the problem of steam loss.
