The effect of preventing impact and equalizing gas is achieved.

[0029] With reference to Figure 1 , the protection assembly includes shell 3, the upper surface of shell 3 is fixedly connected to the lower surface of upper cover plate 2, and the lower surface of shell 3 is fixedly connected with lower cover plate 5.

[0030] Specifically, lower cover plate 5 is invertedly buckled below shell 3, and the edge of the lower side overhanging part thereof protrudes from shell 3, so that the two not only can be sealed by welding but also the whole heat exchanger is supported by the lower side overhanging part of lower cover plate 5.

[0031] With reference toFigure 2 and Figure 3 The inside of the shell 3 is provided with the outer coil pipe 4, the inside of the shell 3 is provided with the inner coil pipe 6, the inside of the upper cover plate 2 is provided with the inner sleeve 8, and the outer wall of the inner sleeve 8 is fixedly connected to the inside of the lower cover plate 5.

[0032] Specifically, the inner coil pipe 6 is installed in the inside of the shell 3, supported by the inlet and outlet pipes of the coil pipe and the corresponding holes in the shell 3, and is located at a certain distance from the bottom of the heat exchanger below the uniform gas plate 7. The inlet pipe 1 is installed in the opening on the right side of the upper cover plate 2, and the lower end is flush with the lower surface of the upper cover plate 2. The inner sleeve 8 is installed through the middle hole of the upper cover plate 2 and the lower cover plate 5, and the upper end extends out of the upper surface of the upper cover plate 2 by a distance, and the lower end extends out of the corresponding hole of the lower cover plate 5 and is correspondingly flanged.

[0033] Referring to Figure 5 and Figure 6 The bottom of the inner sleeve 8 is provided with a first liquid suction hole 13, and the inside of the inner sleeve 8 is provided with a liquid outlet pipe 9. The bottom of the liquid outlet pipe 9 is provided with a second liquid suction hole 14.

[0034] Specifically, the inner sleeve 8 and the bottom of the liquid outlet pipe 9 are provided with the first liquid suction hole 13 and the second liquid suction hole 14. The liquid suction holes enter the annular area of the inner sleeve 8 and the liquid outlet pipe 9, and finally discharge the heat exchanger.

[0035] Working principle: when the condenser needs to be used, the high-temperature gaseous refrigerant vertically enters the inlet pipe 1 of the heat exchanger, and after entering the internal space of the shell 3, it first contacts the uniform gas plate 7, wherein the plate surface 12 of the uniform gas plate 7 is opposite to the front of the inlet pipe 1 on the right side of the upper cover plate 2, and the airflow direction is turned by ninety degrees after entering the coil pipe space through the recess formed by the gap slot 10 and the corresponding protrusion 11 on the uniform gas plate 7. Through the action of the inner coil pipe 6 and the outer coil pipe 4, the high-temperature gaseous refrigerant is cooled on the surface of the coil pipe and condensed into high-temperature liquid refrigerant and drops to the bottom of the heat exchanger. The liquid-phase refrigerant at this position enters the annular area of the inner sleeve 8 and the liquid outlet pipe 9 from the first liquid suction hole 13 and the second liquid suction hole 14 at the bottom of the inner sleeve 8 under the pressure difference between the inside and outside of the heat exchanger, and finally discharges the heat exchanger through the liquid outlet pipe 9. In the above process, the uniform gas plate 7 first prevents the direct impact of the airflow on the coil pipe, and also plays a uniform gas effect. Secondly, the uniform gas plate 7 changes the airflow entering direction from straight blowing to flat blowing, greatly reducing the impact on the coil pipe, and also reducing the impact of the airflow on the bottom condensate, preventing the phenomenon of gaseous refrigerant being discharged from the liquid outlet pipe 9 before completing heat exchange, so that it is fully heat exchanged.

[0036] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
