Abstract
The utility model relates to a highly-efficient tube-shape heat exchanger, belonging to machinery field, including a drum, a heat exchanging tube, a seal head, a tube plate and a connection tube and etc; wherein, the heat exchanging tube is a long and circular tube. The utility model gets rid of the shortcomings in traditional heat exchanger, thereby making the heat exchanger transmit more heat in unit time and unit heat transmission area. The heat exchangers with long and circular tubes are excellent in heat transmission, which enhances the heat transmission efficiency. The resistance for a shell side decreases; thereby the energy and consumption are reduced. Also, the manufacturing of the device is convenient.
Description
Technical field
The utility model relates to a kind of high-efficiency heat exchanger equipment, belongs to the plant equipment field.
Background technology
Tradition heat exchanger tube major part all is a pipe, and these traditional heat exchangers manufacturings are simple, and expense is few, but its heat-transfer effect is all not good, and the heat exchanger pressure drop is big, and kinetic equation loss is big.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that existing heat exchanger exists, and a kind of high-performance heat exchanger is provided, and makes heat exchanger in the unit interval, and the heat that the unit heat transfer area transmits is more.
The purpose of this utility model is achieved by following technical proposals.
The utility model is a kind of oval heat exchange of heat pipe, mainly constitute by cylindrical shell, heat exchanger tube, end socket, tube sheet, adapter, heat exchanger tube is connected with tube sheet by seal washer, import and export adapter, end socket are connected with cylindrical shell, end socket and tube sheet seal by seal washer, seal with seal washer between pressing plate and the end socket.Wherein heat exchanger tube is oval pipe, and its length of straight flange is 1.2-5 with the scope of the ratio L/D of arc diameter.
The beneficial effects of the utility model:
(1) tube side and shell side heat transfer property all increase, and heat transfer improves 8%～20% and 21%～34% respectively with the flow resistance combination property:
(2) the shell side resistance is little, and shell-side pressure drop has reduced by 26%～42%, reduces the energy-saving and cost-reducing effect of playing;
(3) manufacturing is easy to process.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Oval heat exchange of heat pipe, mainly be made of cylindrical shell, heat exchanger tube, end socket, tube sheet, adapter, heat exchanger tube is connected with tube sheet by seal washer, and import and export adapter, end socket are connected with cylindrical shell, end socket and tube sheet seal by seal washer, seal with seal washer between pressing plate and the end socket.Wherein heat exchanger tube is oval pipe, and its length of straight flange is 1.2-5 with the scope of the ratio L/D of arc diameter.
Tube side: enter heat exchanger import end socket 14 by the hot fluid after the heater heating through tube side entrance sleeve 1, enter oval pipe tube bank 10 then and emit heat, flow out through outlet end socket 5 and tube side discharge connection 6 at last.On import and export are taken over, flowmeter, temperature measuring set and differential manometer etc. can be installed.
Shell side: cold air is sent into cold fluid in the cylindrical shell through shell side entrance sleeve 3 by air blast, obtains the flow passage of cold fluid between cylindrical shell 9 and oval pipe tube bank 10 of heat, directly flows out through shell side discharge connection 11 at last.
Be surrounded by insulation material on the heat exchanger shell, have heat-insulating property preferably.Each junction all possesses better seal and reliability.
Claims (2)
