Every sheet wiper is equidistantly provided with mixed flow mouth, mixed flow mouth on adjacent wiper shifts to install, mixed flow mouth can upset the former helical flow state of cooling water, the cooling water in heating surface bank is made to be in better turbulence state, cooling water in heating surface bank can carry out heat convection, good effect of heat exchange with refrigerant well.
The two side of the lateral border of described wiper is provided with reinforcement, and reinforcement can strengthen intensity and the scuff resistance of the lateral border revolving scraping blade further.
The thickness of described wiper is 4mm-8mm, is preferably 5mm.
The radius of described clean spiral bar is 8/9ths or 7/9ths of heat exchanger tube radius, therefore clean spiral bar can not occupy the too many volume of heat exchanger tube, too large resistance can not be formed to cooling water flow, heat exchanger tube can be flowed out fast after cooling water and refrigerant heat exchange, can not be trapped in heat exchanger tube and affect heat exchange, thus improve heat exchange efficiency of the present utility model.
Described plastics are polyether-ether-ketones.
The beneficial effects of the utility model are:
(1) the clean spiral bar structural design advantages of simple of this kind of shell and tube condenser, the length ratio of clean spiral bar and heat exchanger tube is suitable, the pitch of wiper is long, therefore, the screw thread quantity that wiper is formed is few, just little to the resistance of cooling water, heat exchanger tube can be flowed out fast after cooling water and refrigerant heat exchange, can not be trapped in heat exchanger tube and affect heat exchange, thus improve heat exchange efficiency of the present utility model, make heat transfer effect of the present utility model better.And the pitch of wiper is long, the area of the heat exchanger tube inwall that wiper strikes off is comparatively large, and cleaning efficiency is higher.And the intensity of clean spiral bar is high, wear-resistant, effectively extends the service life of shell and tube condenser.More have plenty of, the utility model is by being designed to spherical or arc-shaped by the lateral border of wiper, even make the lateral border intensity of wiper higher, more wear-resistant by the thickness of the lateral border increasing wiper, thus the service life of shell and tube condenser is extended.
(2) also have, the two side of the lateral border of the utility model wiper is provided with reinforcement, and reinforcement further enhancing intensity and the scuff resistance of the lateral border of wiper.
