4 pressure are higher than outlet chamber 2 pressure, and out-of-balance force reaches will make guiding valve 3 overcome the tensile force of spring guard 8 simultaneously anti-during certain value
To motion, now guiding valve leading portion 17 leaves the inwall of outlet nozzle 1 and is continuously increased flow area, and inlet chamber 4 and outlet chamber 2 are even
Logical, QI invigorating operation can be carried out.
Control air compensation device of the present invention includes controlling high-voltage power supply air compensation device or power air compensation device.Described power air compensation device,
Referring to Fig. 3, main inclusion power outlet nozzle 20, driven fan 21 and QI invigorating adapter 22, driven fan 21 is placed in outlet nozzle 20
Portion, outlet nozzle 20 is connected with power QI invigorating source 23 by QI invigorating adapter 22.The operating of driven fan 21 and stall control power
The power QI invigorating process to air channel for the QI invigorating source 23, is additionally provided with exsiccator 19 in outlet nozzle 20.Exsiccator 19 is to filling into air channel
Gas is dried process.Exsiccator 19 is arranged between driven fan 21 and air channel, and the operating of driven fan 21 controls power
The power QI invigorating process to air channel for the QI invigorating source 23.
High pressure QI invigorating source QI invigorating is controlled to be using the pressure differential between high pressure QI invigorating source and low-pressure area air channel, high by controlling
The break-make of the QI invigorating adapter between pressure QI invigorating source and low-pressure area air channel, realizes the QI invigorating process to air channel for the high pressure QI invigorating source.Referring to
Fig. 4, controls high pressure QI invigorating source air compensation device to include outlet nozzle 30 and high pressure QI invigorating source 33, outlet nozzle 30 and high pressure QI invigorating source 33 are passed through
QI invigorating adapter 32 is connected, and QI invigorating adapter 32 is provided with control valve 31, is additionally provided with exsiccator 34 in outlet nozzle 30.Exsiccator 34 is pacified
Dress is pressed close at the wall of air channel, the break-make of the control valve 31 and valve folding extent control high pressure QI invigorating source 33 QI invigorating process to air channel,
Exsiccator 34 can be dried process to the gas filling into air channel.Using the pressure between high pressure QI invigorating source 33 and low pressure air channel area
Difference, realizes the QI invigorating process to air channel for the high pressure QI invigorating source 33.
The operation principle of the enclosed air channel structure for enhanced heat exchange of the present invention is:
By adding air compensation device, QI invigorating is carried out to enclosed air channel, it is possible to increase in air channel, flow through the exchanging air of heat exchanger heat-exchanging tube
The pressure of body medium, improves its density, increases heat exchanger heat-exchanging tube outer wall surface convective heat-transfer coefficient, efficient hardening enclosed air channel
Interior heat transfer effect.Hereinafter operation principle is further described:
Heat exchanger is arranged on the heat of the release of collecting device unit heat dissipation element in air channel, and by heat exchanger working medium by heat
Amount is taken away.In air channel, the heat transfer model of recuperated gas medium and heat exchanger outer wall is fluid cross-flow tube bank external forced to spreading
Heat arranges arrangement mode, r it is assumed that heat exchanger heat-exchanging tube is forkeNumber scope is 103～2 × 105, bank of tubes correction factor is εn, reference
The horizontal staggered tubes bundle average surface heat transfer coefficient of plunderring of " thermal conduction study " fourth edition table 6-8 fluid that Yang Shiming, inscription on pottery select are write calculates pass
It is formula, the nusselt number nu and surface coefficient of heat transfer h of convection heat transfer' heat-transfer by convection are respectively as follows:
Wherein,s1、s2For restraining spatial arrangement size, d is in air channel
Footpath.It is assumed that keeping constant to flow fluid temperature (F.T.), and ignore the temperature change of the heat exchange pipe outer wall wall causing due to QI invigorating.
Can be obtained by formula (1) (2):
ε in the right-hand member items of formula (3)n、d、s1、s2Keep constant, ignore to flow in the air channel because QI invigorating causes (1)
The temperature change of the heat exchange pipe outer wall of gas and heat exchanger (3), then cp、λf、λwApproximate constant, the viscosity, mu of gas of the same race
Negligible with varying less of pressure, then the change of heat transfer coefficient h only with flow through air channel (1) section at heat exchanger (3) heat exchanger tube
Gas density relevant with the product ρ v of flow velocity.If the heat exchanger before and after QI invigorating (3) heat exchange pipe external surface heat transfer coefficient is respectively
h、h*, then have:
It is assumed that rotation speed of fan is constant after air channel carries out QI invigorating, then the volume flow at fans entrance is constant, i.e. entrance section
Induction air flow ratio constant, and the gas density at entrance section changes.It is assumed that gas pressure intensity linearly becomes along air channel in air channel
Change, air channel inner blower porch gas temperature constant for 340k, air compensation device is carried out after QI invigorating to air channel, and at fans entrance, gas is close
Degree increases, and in the case that rotation speed of fan is constant, fan pressure, by increase by a small margin, ignores the change of blast herein, by blower fan wind
Pressure constant for 0.02mpa, subsequent analysis heat exchange will be made it should be noted that ignore the simplification that blast increases by a small margin and process herein
Device heat exchange pipe external surface convective surface heat transfer coefficient increase amplitude relatively conservative.If the fans entrance under original state
The pressure of section and outlet is respectively as follows: p1=0.09mpa, p2=0.11mpa, the gas flow supplementing is original air channel gas
The 25% of amount, can be calculated QI invigorating rear fan entrance section and the gas pressure of outlet is respectively p1*=0.115mpa, p2*
=0.135mpa, at fans entrance section before and after QI invigorating, gas density is respectively ρ1=1.178kg/m3, ρ1*=1.383kg/m3,
And flow velocity is constant at fans entrance section, can obtain:
In air channel (1), each section mass flow is equal everywhere again, and that is, each section gas density and the product of flow velocity keep not
Become, therefore flow through air channel (1) section at heat exchanger (3) place in gas, have:
Flow through the gas flow rate size approximately equal in heat exchanger (3) place air channel (1) section before and after QI invigorating, then have:
Bring formula (4) into by formula (7) can obtain:
Referring to Fig. 5, analyze in conjunction with above, air channel adds air compensation device and carries out QI invigorating to air channel, before QI invigorating, press at fans entrance
Power is p1=0.09mpa, gas density is ρ1=1.178kg/m3, after QI invigorating, at fans entrance, pressure increases to 0.115mpa,
Density increases to ρ1*=1.383kg/m3, flowing through the recuperated gas Media density at heat exchanger heat-exchanging tube increases by 17.4%, heat exchange
Device heat exchange pipe external surface convective surface heat transfer coefficient increases 10.1% it is known that adding air compensation device to air channel in air channel low-pressure area
Carry out QI invigorating, it is possible to increase flow through the pressure of the recuperated gas medium of heat exchanger heat-exchanging tube in air channel, improve its density, and then more
Significantly increase the convective surface heat transfer coefficient outside heat exchanger heat-exchanging tube, thus heat exchange effect in efficient hardening enclosed air channel
Really, ensure the Effec-tive Function of heat dissipation equipment unit and lift its service life and security reliability.
