Embodiment one
As shown in Figure 1 and Figure 4, gas-liquid separate component includes the refrigerant pipe 105 for refrigerant circulation.Refrigerant pipe 105 is fixed on
On part demarcation plate 103 and running through demarcation plate 103, the profile of refrigerant pipe 105 is in zigzag or class zigzag, and the one of refrigerant pipe 105
Hold (left end in Fig. 4) that there is the first nozzle 105a, the other end (right end in Fig. 4) of refrigerant pipe 105 has the second nozzle 105b.The
One nozzle 105a and the second nozzle 105b is respectively placed in two adjacent cavitys, and the height where the first nozzle 105a is greater than the
Height where two nozzle 105b.In the present embodiment, the first nozzle 105a is as gaseous coolant nozzle, the second nozzle 105b conduct
Liquid refrigerants nozzle.
The aperture of first nozzle 105a can be 3mm-10mm, and the aperture of the second nozzle 105b can be 1mm-5mm.Preferably,
The aperture of first nozzle 105a is greater than or equal to the aperture of the second nozzle 105b.
Heat exchanger as condenser in use, its process as shown in Fig. 2, high pressure gaseous refrigerant from air inlet pipe 106 into
Entering heat exchanger, then flows through the heat dissipation of heat exchanger tube 104, part refrigerant can be condensed into liquid, since heat exchanger is in flat position,
Liquid refrigerants can be collected at the downside of the first header 101 and the second header 102；There is pressure since refrigerant flows in heat exchanger tube 104
Power loss, thus refrigerant pressure in each front process of heat exchanger can the refrigerant pressure in process later greatly, before process it is empty
Liquid refrigerants in chamber can successively pass through the second nozzle 105b and the first nozzle 105a, subsequently into process cavity below；By
It can be collected at the upside of the first header 101 and the second header 102 in gaseous coolant, therefore gaseous coolant then continues the process by setting
It radiates by heat exchanger tube 104, enters in process cavity below without going past refrigerant pipe 105, finally complete condensed refrigerant
Heat exchanger is discharged by outlet tube 107.Due to the liquid state refrigerant separation in heat transfer process, liquid refrigerants is in time from refrigerant pipe
Drain in 105, gaseous coolant then continues through the heat exchange of heat exchanger tube 104, to effectively improve the condensing heat-exchange performance of heat exchanger.
Heat exchanger is as evaporator in use, its process is as shown in figure 3, gas-liquid two-phase low temperature cold after restricting element
Matchmaker enters heat exchanger from outlet tube 107, then flows through 104 evaporation endothermic of heat exchanger tube, and part refrigerant can be evaporated into gaseous state, due to
Heat exchanger is in flat position, and gaseous coolant can be collected at the upside of the first header 101 and the second header 102；Since refrigerant exists
Flowing has the pressure loss in heat exchanger tube 104, so the refrigerant pressure in each front process of heat exchanger can be greatly later in process
Refrigerant pressure, before gaseous coolant in process cavity can successively pass through the first nozzle 105a and the second nozzle 105b, then into
Enter below in process cavity；Since liquid refrigerants can be collected at the downside of the first header 101 and the second header 102, therefore liquid is cold
Matchmaker then continues to absorb heat by the process of setting by heat exchanger tube 104, enters in process cavity below without going past refrigerant pipe 105,
Heat exchanger is discharged by air inlet pipe 106 in refrigerant after finally completing evaporation.Since the liquid state refrigerant in heat transfer process separates,
Gaseous coolant is drained from refrigerant pipe 105 in time, and liquid refrigerants then continues through the heat absorption evaporation of heat exchanger tube 104, to effectively mention
The evaporation and heat-exchange performance of high heat exchanger.
The heat exchanger of the present embodiment effectively realizes refrigerant in heat transfer process by increasing refrigerant pipe 105 on demarcation plate 103
In gas-liquid separation, improve the performance of heat exchanger.

Second conduit 109 is each attached on part demarcation plate 103 and through demarcation plate 103, in the first conduit 108 and the second conduit 109
In be provided with check valve 110, the 110 direction phase of check valve in the check valve 110 and the second conduit 109 in the first conduit 108
Instead.In the present embodiment, the first conduit 108 is used as gaseous coolant separating pipe, and the second conduit 109 is used as liquid refrigerants separating pipe.The
Height where one conduit 108 is greater than the height where the second conduit 109.The difference between this embodiment and the first embodiment lies in refrigerant
Pipe 105 is substituted using the first conduit 108 and the second conduit 109, realizes the function being the same as example 1, heat exchanger is as cold
Refrigerant flow path when condenser and evaporator is the same as example 1, and details are not described herein again.
The heat exchanger of the present embodiment effectively realizes gas-liquid separation of the refrigerant in heat transfer process, improves the property of heat exchanger
Energy.Gravity is formed by between the first nozzle 105a of refrigerant pipe 105 in embodiment one and the second nozzle 105b also without overcoming
Difference avoids can not achieve the liquid state separation of refrigerant because front and back process pressure difference is inadequate.
Embodiment three
