Case study on implementation
When heat exchange, band is that refrigerant input port 7 enters after U-tube 15 from defeated from refrigerant to the refrigerant traffic direction of compression
Outlet 5 exports, and the absorption higher refrigerant of thermal temperature to circulate out in refrigeration equipment enters U-shaped from the refrigerant input port 7 of lower end
The next column channel of curved many groups of U-tubes 15, the bending circular arc flowed through to bottom enter 15 previous column channel of U-tube, and
It is exported by the refrigerant delivery outlet 5 of upper end, for refrigerant during this flowing, the cooling water with hydraulic pressure is from water inlet pipe 19 from heat exchange
The right end of cylinder 14 enters in inner cavity the inner cavity for flowing and filling heat exchanger cylinder 14 and continues in the presence of hydraulic pressure to heat exchanger tube
14 inner cavity of body left end flowing and 14 inner cavity of heat exchanger cylinder package U-tube 15, while with the higher refrigerant of temperature in U-tube 15
Heat transmitting heat exchange is carried out, the heat that cooling waterside absorbs refrigerant is flowed to left-hand simultaneously, and is constantly entering heat exchanger cylinder
The outlet pipe 18 connect from 14 left end of heat exchanger cylinder under the pressure of the cooling water of 14 inner cavities is sent out, at this point, cold in outlet pipe 18
But water carries out heat exchange temperature raising, the refrigerant temperature in U-tube 15 in 14 inner cavity of heat exchanger cylinder with the refrigerant in U-tube 15
Lower cooling, the raised cooling water of temperature cools down after outside carries out heat release, persistent loop application；Refrigerant is in this process
The cooled water of middle heat, which absorbs, carries out heat exchange, and temperature reduces cooling, send to the node of refrigeration equipment and gives the components such as compressor drop
Temperature.
The refrigerant for needing heat exchange to cool down is inputted from the refrigerant input port 7 of 14 left side lower end of heat exchanger cylinder, after flowing through U-tube 15
From the refrigerant delivery outlet 5 of upper end export because temperature it is high refrigerant density it is low relative to temperature refrigerant it is small, be easier to upstream
It is dynamic, it also more can be carried out heat exchange, during refrigerant is flowed in U-tube 15 with synchronous heat exchange, the refrigerant meeting that gradually cools down
The phenomenon that sinking also carries out heat exchange cooling with the high refrigerant of temperature simultaneously with U-tube 15, further generates heat exchange function
Effect.
Cooling water enters inner cavity from the water inlet pipe 19 of the right end of heat exchanger cylinder 14, fills up the interior of heat exchanger cylinder 14 from top to bottom
Chamber, the refrigerant heat exchange cooling that can enter from below to up to 15 lower end pipeline of U-tube, as cooling water continues into, heat exchange
The raised cooling water of temperature is smaller than the rear cooling water density low into temperature afterwards, and the raised cooling water of heat exchange temperature is to overflow
It rises and is discharged from the outlet pipe 18 of 14 left end of heat exchanger cylinder, carried out in complete entire flow of cooling water with the refrigerant in U-tube 15
The process of heat exchange.
Above structure, heat exchange mode are direct, it is well known that the heat exchange of the conduction of liquid and the convection current because of temperature difference generation
Mode is prepreerence heat exchange mode, good effect of heat exchange.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
Should all it cover within the scope of the present invention.
