Circulation, the circulation path of refrigerant are to enter supercooling bypass pipe 3 from first node, and shunt two-way in first node, are flowed all the way
To supercooling tube group 2, another way flow direction supercooling bypass pipe 3, the refrigerant of flow direction supercooling bypass pipe 3 flows to third node, in point three
Node shunts two-way again, flows to the first pipeline section all the way, in second node, flows through the refrigerant all the way of supercooling tube group 2 and flows through
The refrigerant all the way of first pipeline section converges, and flow direction shunts bypass pipe 5, flows to the second pipeline section at least in the another way of third node
Portions flow through the refrigerant all the way for shunting bypass pipe 5 and at least partly pipeline section for flowing through the second pipeline section in fourth node
Refrigerant converges all the way, flows to other pipeline sections of the second pipeline section, forms three roads and shunts, when the refrigerant of gas-liquid mixture phase is from the
When one node enters, if not being equipped with the supercooling bypass pipe 3 of supercooling check valve 4 and equipped with the shunting bypass pipe for shunting check valve 6
5, refrigerant resistance is larger, can reduce heat exchange efficiency, influence heating effect.

At least partly pipeline section of second pipeline section is to fourth node.That is, first path is first flow path to third flow path；Second path is the
Two flow paths to the 4th flow path are to third flow path；Third path is second flow path to the 5th flow path.Heat exchanger leads in heating operation
Multipath shunting is crossed, larger resistance when refrigerant enters first node is alleviated, flow path resistance loss is reduced, improves system
The thermal efficiency.
In this way, being achieved that heat exchanger in heating operation, realizes that heat exchanging device is shunted by check valve, can subtract
Mini system complexity reduces the voltage loss generated in heating by supercooling tube group 2, to improve system heat exchange effect
Rate.
Optionally, the quantity of the heat exchanger tube of the first pipeline section of supercooling bypass pipe 3 set of heat exchange tubes 1 in parallel, is less than or waits
In the quantity of the heat exchanger tube of its supercooling tube group 2 in parallel.
Optionally, for heat exchanger in heating operation, the flow path of refrigerant is three paths, and a paths are from first node
Second node is arrived by supercooling tube group 2, arrives fourth node by shunting bypass pipe 5；One paths are first node by supercooling
Bypass pipe 3 arrives third node, by the first pipeline section to second node, arrives fourth node by shunting bypass pipe 5；Another path is
First node arrives third node by supercooling bypass pipe 3, by at least partly pipeline section of the second pipeline section to fourth node.That is, the
One path is first flow path to third flow path；Second path is second flow path to the 4th flow path to third flow path；Third path is

When the quantity of 2 heat exchanger tube, heat exchanger in heating operation, just can more preferably realize multipath shunt, alleviate refrigerant into
Enter larger resistance when first node, reduces flow path resistance loss, improve heating efficiency.
In this way, being achieved that heat exchanger in heating operation, realizes that heat exchanging device is shunted by check valve, can subtract
Mini system complexity reduces the voltage loss generated in heating by supercooling tube group 2, to improve system heat exchange effect
Rate.
Optionally, the quantity of the heat exchanger tube of the first pipeline section of supercooling bypass pipe 3 set of heat exchange tubes 1 in parallel, is less than or waits
In the quantity of the heat exchanger tube for at least partly pipeline section for shunting second pipeline section in parallel of bypass pipe 5.
Optionally, for heat exchanger in heating operation, the flow path of refrigerant is three paths, and a paths are from first node
Second node is arrived by supercooling tube group 2, arrives fourth node by shunting bypass pipe 5；One paths are first node by supercooling
Bypass pipe 3 arrives third node, by the first pipeline section to second node, arrives fourth node by shunting bypass pipe 5；Another path is

In third node, the refrigerant flow to circulate to the 5th path can be greater than the refrigerant flow to circulate to the 4th path for agent, at this point,
The effect for shunting bypass pipe 5 can be weakened severely, and the setting for shunting bypass pipe 5 does not just have predictive role, can not allow refrigerant
Circulation realize multipath shunt, cannot alleviate well flow path resistance loss.So when first pipeline section of set of heat exchange tubes 1
When the quantity of heat exchanger tube is less than or equal to the quantity of the heat exchanger tube of at least partly pipeline section of the second pipeline section, heat exchanger is in heating operation
When, it just can more preferably realize that multipath shunts, alleviate larger resistance when refrigerant enters first node, reduce flow path resistance
Power loss, improves heating efficiency.

One path is first flow path to third flow path；Second path is second flow path to the 4th flow path to third flow path；Third path is
Second flow path is to the 5th flow path.If the number of heat exchange tubes of at least partly pipeline section of the second pipeline section is greater than the heat exchanger tube of supercooling tube group 2
Quantity, at least partly pipeline section both ends flow pressure difference of the second pipeline section can be greater than 2 both ends flow pressure difference of supercooling tube group, then make
For cryogen in first node, the refrigerant flow to circulate to first path can be greater than the refrigerant flow to circulate to third path, this
When, the effect of supercooling bypass pipe 3 can be weakened severely, and the setting of supercooling bypass pipe 3 does not just have predictive role, can not allow refrigeration
Agent circulation realizes that multipath shunts, and cannot alleviate flow path resistance loss well.So the number of the heat exchanger tube when supercooling tube group 2
When amount is greater than or equal to the quantity of the heat exchanger tube of at least partly pipeline section of the second pipeline section, heat exchanger, just can be in heating operation
It is more preferable to realize that multipath shunts, larger resistance when refrigerant enters first node is alleviated, flow path resistance loss is reduced, mentions
