Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment of the present utility model is as follows: a kind of helically twisted heat exchange of heat pipe of Novel interphase is mainly made up of tube side and shell side, and the fluid of tube side flow is referred to as tube side fluid, and the fluid of shell fluid flow is referred to as shell-side fluid.
The flow process of tube side fluid is as follows: tube side fluid is entered the import bobbin carriage [2] of tube side inlet part by tube side import [1], and due to import channel flange [3], the sealing function of import bobbin carriage flange gasket [15], tube side fluid will not seepage；Then, through the shunting of import tube sheet [4], tube side fluid enters each heat exchange pipeline of the alternate helically twisted heat-exchanging tube bundle [5] of tube side heat exchanging part, carries out heat exchange with the shell-side fluid of shell side；Subsequently, through heat exchange tube side fluid through outlet tube sheet [12] collect effect, tube side fluid enters the outlet bobbin carriage [10] of tube side exit portion, alternate helically twisted heat exchange of heat pipe is flowed out by tube side outlet [9], due to outlet channel flange [8], the sealing function of outlet bobbin carriage flange gasket [11], tube side fluid will not seepage.
The flow process of shell-side fluid is as follows: shell-side fluid is entered the interior tube side fluid with tube side of cylinder [13] by shell side import [14] and carries out heat exchange, barrier effect due to deflection plate [6], shell-side fluid has the glide path of a "the" shape at shell side, which increases the flow process of shell-side fluid；Subsequently, the shell-side fluid through heat exchange is flowed out the helically twisted heat exchange of heat pipe of this Novel interphase by shell-side outlet [7].
In the helically twisted heat exchange of heat pipe of Novel interphase that this utility model relates to, alternate helically twisted heat-exchanging tube bundle [5] is made up of Novel interphase spiral torsional curved tube, and this Novel interphase spiral torsional curved tube is made up of import [21], inducer [22], straight length 1 [23], clock wise spirals distortion section [28], straight length 2 [24], counter-clockwise helical distortion section [27], outlet section [25] and outlet [26]；Fluid creates periodic spin flowing along with the cyclically-varying of tube wall shape, define the Secondary Flow being tangential on tube wall, this phenomenon adds the turbulence effect of fluid, convection cell wall boundary region and schmutzband and produces the strongest destruction, makes the coefficient of heat transfer improve；There is good versatility between parts and the common tube shell heat exchanger of the helically twisted heat exchange of heat pipe of this Novel interphase, have preferable development prospect and actual application value widely.
