The circulation area of section 10, i.e. adds the flowing pressure in runner, reduces the flow direction of gravity convection body 70
Impact, when two of the section of being in charge of 10 outlets are vertically arranged, make the flows flowing to two outlets basic
Identical, even if the shunting of three-way pipe is uniform, thus ensure that the heat exchange at each position of heat exchanger is uniform, carry
The high quality of product, and then add the competitiveness of product in market.
In one embodiment of the invention, as it is shown on figure 3, throttling element 50 is restrictor ring, restrictor ring card
It is connected in main leg 20.
In this embodiment, throttling element 50 is restrictor ring, in the situation of the restriction effect ensureing throttling element 50
Under, it is possible to make the more uniform of pressure distribution in passage, make to flow to the flow bases of two outlets further
This is identical, even if the shunting of three-way pipe is uniform, thus ensure that the heat exchange at each position of heat exchanger is uniform,
Improve the quality of product, and then add the competitiveness of product in market, it addition, the connected mode of clamping,
Easy installation and removal, it is simple to change after restrictor ring damages.
In one embodiment of the invention, as shown in Figure 4 and Figure 5, the tube wall of the section of being in charge of 10 is to supervisor
Section 20 sunken inside forms restriction 60, and restriction 60 extends in main leg 20, in restriction 60 just
Face to import is throttleng surface 30.
In this embodiment, restriction 60 is formed by the tube wall depression of the section of being in charge of 10, on the one hand, add
Bonding strength between restriction 60 and the section of being in charge of 10, thus reduce restriction 60 and the section of being in charge of 10
Between there is the probability of fracture, and then add the competitiveness of product in market, on the other hand, restriction 60
It is made into integration with the section of being in charge of 10, thus adds the production efficiency of product, and then reduce the production of product
Manufacturing cost, it addition, just face to import is throttleng surface 30 in restriction 60, adds the stream in runner
Dynamic pressure, reduces the impact of the flow direction of gravity convection body 70, when two of the section of being in charge of 10 outlets vertically
When arranging, make the flow flowing to two outlets essentially identical, even if the shunting of three-way pipe is uniform.
In one embodiment of the invention, as shown in Figure 4, the cross sectional shape of restriction 60 is V-arrangement,
Two inclined-planes of the restriction 60 of V-arrangement are throttleng surface 30.
In this embodiment, the restriction 60 of V-arrangement is in the case of satisfied throttling requires, restriction 60 is also
The effect of water conservancy diversion and shunting can be played, make the flow flowing to two outlets essentially identical further, even if three
The shunting of siphunculus is uniform, thus ensure that the heat exchange at each position of heat exchanger is uniform, improves the product of product
Matter, and then add the competitiveness of product in market.
In one embodiment of the invention, as it is shown in figure 5, restriction 60 includes two inclined-planes and difference
Angle between the end face being connected with two inclined-planes, and two inclined-planes along one end of main leg 20 to the other end
Being gradually reduced, two inclined-planes are throttleng surface 30 with end face.
In this embodiment, the throttling action that end face and inclined-plane play, reduce fluid 70 from main leg 20
Flow to the circulation area of the section of being in charge of 10, i.e. add the flowing pressure in runner, reduce gravity convection body
The impact of the flow direction of 70, when two outlets of the section of being in charge of 10 are vertically arranged, makes to flow to two outlets
Flow is essentially identical, even if the shunting of three-way pipe is uniform, thus ensure that the heat exchange at each position of heat exchanger
Uniformly, improve the quality of product, and then add the competitiveness of product in market, it addition, inclined-plane can also
Play the effect of water conservancy diversion and shunting, make the flow flowing to two outlets essentially identical further, though three-way pipe
Shunting uniform, thus ensure that the heat exchange at each position of heat exchanger is uniform, improve the quality of product,
And then add the competitiveness of product in market.
In one embodiment of the invention, the section of being in charge of 10 and main leg 20 are integral type structure.
In this embodiment, the section of being in charge of 10 and main leg 20 are integral type structure, on the one hand, add point
