Abstract
A heat exchanger with unequal cross-sectional areas for fixed tubular channel assemblies with large flow difference of heat exchange media on two sides solves the problem that the heat exchange efficiency is increased by enabling the media in an inner tube to pass through at high flow speed while enabling the inner tube to have enough exchange area. It includes outer pipe and inner pipe, and is characterized by that in the inner pipe an "object" is mounted along the longitudinal central position so as to reduce volume of inner pipe and raise medium flow rate. The heat exchanger can be widely applied to occasions with large flow difference of heat exchange media at two sides.
Description
The utility model relates to the long-pending heat exchanger of unequal section of the fixed pipe channels assembly that is used for the both sides heat exchange, the different contacts side surfaces of various media and conduit wall.
Mostly existing tubing heat exchanger is to be made up of internal and external double-layer, passes through identical or different medium in the inner and outer pipes respectively.Under the certain situation of diameter of inner pipe, if wherein a kind of flow of medium is less, velocity of medium reduces, and causes its heat exchanger effectiveness to descend.
The purpose of this utility model is that a kind of interior pipe medium and interior medium of outer tube of should making of design has enough big contact area, holds the volume reducing of medium in making again in the pipe, makes medium have higher flow velocity, so that improve the heat exchanger of heat exchange efficiency.
Design philosophy of the present utility model is on the basis of existing thimble tube heat exchanger, in the centre of interior pipe " object " is installed, and with pipe volume in reducing, correspondingly improves the flow velocity of its medium.The original surface area of pipe in keeping simultaneously, i.e. heat exchange area is to improve heat exchange efficiency.
Narrate its structure with reference to the accompanying drawings.
A kind of unequal section of fixed pipe channels assembly amasss heat exchanger, and it comprises outer tube 1 and interior pipe 2, it is characterized in that along the axial centre position of interior pipe 2 " object " 3 being installed.
For the heat exchanger that many interior pipes are arranged, also " object " can be installed in interior pipe, to improve heat exchange efficiency.Be a kind of long-pending heat exchanger of unequal section of fixed pipe channels assembly, it comprises pipe 2 in outer tube 1 and the Duo Gen, it is characterized in that along the axial centre of interior pipe 2 " object " 3 being installed.
" object of installing in the interior pipe 2 of above-mentioned two kinds of heat exchangers " 3 can be the solid material of different shape or light pipe, improve heat exchanger effectiveness, increase the tubing of heat exchange area through the bellows of processing etc., in these materials are installed in one heart in the pipe 2 or pass from interior pipe 2.
If solid material is as long as be installed in it in interior pipe 2 by supporting, the volume of pipe 2 in can reducing improves velocity of medium.If tubing can be installed in the interior pipe 2 by support after one end or the closed at both ends, or its one or both ends are fixed on the one or both ends of interior pipe 2.Pipe 2 had so not only reduced the volume of interior pipe 2, and has increased the heat exchange area of interior pipe 2 medium and external agency in tubing can also run through, and improved heat exchange efficiency more.
Use this heat exchanger can keep the original surface area (heat exchange area) of interior pipe, the pipe volume increases velocity of medium in can reducing again, the raising heat exchange efficiency.This heat exchanger is applicable to that heat exchange amount is big, rate-of flow differs bigger occasion.
Description of drawings:
Fig. 1 is the complete section schematic diagram of embodiment 1, and Fig. 2 is the complete section schematic diagram of embodiment 2.Fig. 3 is the complete section schematic diagram of embodiment 3, and Fig. 4 is the A-A cutaway view.
Embodiment:
Example 1.
A kind of tubular type unequal section amasss heat exchanger, and it can comprise outer tube 1 and interior pipe 2, and " object " 3 is tubing, in the pipe 2, manages 2 two ends in the two ends of " object " 3 are welded in being installed in one heart.Make " object " 3 one-tenth closed states.The volume reducing of pipe 2 causes wherein velocity of medium increase in making behind installation " object " 3, improves heat exchange efficiency.
Example 2:
A kind of tubular type unequal section amasss heat exchanger, with example 1 difference be that " object " 3 passes from interior pipe 2, the contact position, two ends of it and interior pipe 2 also will be welded.Because " object " the 3rd, siphunculus will be so the medium in the outer tube 1 also will therefrom flow through.Increased heat exchange area like this, again.
Example 3:
A kind of tubular type unequal section amasss heat exchanger, manages 2 in many of the parallel installations in outer tube 1, and " object " 3 all is installed in the pipe 2 in every with one heart." object " 3 is solid cylinder, and it is installed in the interior pipe 2 by supporting 8.Outer tube 1 and interior pipe 2 are by flange 4 assemblings.After medium in the interior pipe 2 is confluxed by flange 4, flow out by the outlet of end cap 5.Medium in the outer tube 1 is passed through by gateway 6,7.
