In traditional winding mode of constant warm tube 2, when constant temperature liquid flows in constant warm tube 2, hot friendship is carried out with constant warm tube 2
Change, and the air outside constant warm tube 2 and thermostat 1, constant warm tube 2 carries out heat exchange so that the temperature of constant temperature liquid different piece and
There is deviation in temperature T, this deviation is denoted as temperature difference T；The temperature difference T differences of constant temperature liquid each section lead to 2 each section of constant warm tube
Non-uniform temperature so that the non-uniform temperature of 1 each section of thermostat, influences black matrix performance.
Constant warm tube winding schemes provided by the invention cause adjacent constant warm tube to be in the arrangement side of " cold and hot uniform alternating "
Formula, any one section of constant warm tube carry out heat exchange with adjacent constant warm tube, so as to fulfill temperature-compensating, largely overcome biography
The defects of non-uniform temperature of thermostat each section caused by winding schemes of uniting.The constant warm tube winding schemes provided by the invention
So that adjacent constant warm tube is in the arrangement mode of " cold and hot uniform alternating ", it is discussed below：
Starting point is in the position for going out thermostatic pump 5 using constant temperature liquid stream, and the position for flowing back to thermostatic pump 5 is terminal, it is clear that constant temperature liquid exists
Temperature difference T is 0 during 5 inside of thermostatic pump, portion smaller, more remote apart from starting point the constant temperature liquid part temperature difference T nearer apart from starting point
Divide temperature difference T bigger；Constant temperature liquid constantly carries out heat exchange in flow process with the external world, and temperature difference T is with constant temperature liquid in constant warm tube 2
In the distance S (hereinafter referred to as distance S) that flows through it is proportional, i.e.,
Δ T=KTS formula 1
Wherein, KTReferred to as heat exchange coefficient, for the solution of the present invention, to some temperature T, K that should determine thatTIt, can for constant
Calculated during under black matrix actual operating conditions, measuring method is as follows, true in temperature T if the total length of constant warm tube 2 is Z
In the case of fixed, the constant temperature liquid temperature T ' in final position is measured, then is understood
For the arbitrary segment X of constant warm tube 20, with X0The segment of adjacent constant warm tube is denoted as X respectively-1And X1, it is described " small
Section " refers to short enough one section of constant warm tube 2, computationally with differential meaning mathematically, the adjacent constant warm tube it is small
Section, refer on 2 winding direction of constant warm tube with X0Segment on an adjacent upper circle and next circle.Constant warm tube 2 is defined along A-B-O roads
The part of diameter is effuser, along the part in O-D-C paths to flow back to pipe, if winding schemes according to the present invention are it is found that X0For
Effuser, then X-1And X1It is to flow back to pipe, if X0To flow back to pipe, then X-1And X1It is effuser, it can thus be appreciated that the present invention carries
The constant warm tube winding schemes of confession cause adjacent constant warm tube to be in the arrangement mode of " hot and cold alternation ".It is " cold and hot to continue with discussion
Connotation uniformly "：
If the total length of constant warm tube 2 is Z, 1 cross sectional radius of thermostat is R, between adjacent constant warm tube kernel of section away from
From for L, X0、X-1、X1Distance of the internal constant temperature liquid apart from starting point is is followed successively by S0、S-1、S1, winding schemes according to the present invention can
To obtain following estimation formula：
Work as X0During for effuser,
Work as X0During to flow back to pipe,
Wherein, Δ Z is the departure of distance S, and magnitude estimation is as follows：
Work as X0During in barrel position,
Work as X0During in basal surface position, Δ Z=2 π R+3 π L-2n π L
Wherein, n is in the coiling of bottom surface, along bottom surface radial direction, by the serial number of the number of turn of outer and interior coiling, works as X0Residing position
When resting against the bottom center O of nearly thermostat 1, n is approximately equal to R close to maximum value, at this time nL because for actual use black matrix and
Speech, R are much larger than L, it is possible to make further approximate：
Work as X0During in barrel position, Δ Z=2 π R
Work as X0During in basal surface position, Δ Z=2 π R-2n π L
It can be seen that the magnitude range of Δ Z is only 2 π R, that is, around one circle of barrel, and constant warm tube 2 is needed in barrel and bottom
Face all winds multiturn, so constant warm tube total length Z is much larger than Δ Z.Ignore the factor of Δ Z, we may safely draw the conclusion：Constant warm tube
Arbitrary segment X0Distance apart from constant temperature pump discharge is approximately equal to sum of the distance of the adjacent constant warm tube apart from constant temperature pump discharge
Constant warm tube total length Z；In conjunction with formula 1, it may be said that the arbitrary segment X of constant warm tube0Temperature difference T and adjacent constant warm tube the temperature difference
The sum of Δ T is always equal, is KTZ carries out heat exchange between adjacent constant warm tube, so as to fulfill temperature-compensating, to a greater extent
Ensure that the temperature of thermostat each section is uniform, improve the performance of black matrix.
