[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0019] like Figure 1-3 As shown, the refrigerant separation device of the refrigeration equipment includes a sealed shell 1. A partition 14 is provided horizontally inside the shell 1. The partition 14 is fixedly connected to the inner wall of the shell 1 in a sealed manner. The partition 14 divides the interior space of the shell 1 into two parts: an upper cavity 11 and a lower cavity 13. The upper cavity 11 is conical, and a columnar structure 12 is formed at the top of the upper cavity 11. The top of the columnar structure 12 has an opening, and a liquid pipe 2 is provided at the opening. The gaseous and liquid refrigerants are introduced through the liquid pipe 2 and enter the upper cavity 11 through the top opening of the columnar structure 12. In addition, a frustum 3 is provided in the upper cavity 11, the bottom wall of the frustum 3 is fixedly connected to the partition 14, and the side wall is parallel to the inner wall of the upper cavity 11. A plurality of triangular guide blocks 6 are evenly arranged between the side wall of the frustum 3 and the inner wall of the upper cavity 11. The triangular guide blocks 6 are oriented in the same direction and all point to the top of the frustum 3. A liquid flow channel is formed by the side wall of the frustum 3, the inner wall of the upper cavity 11 and the plurality of triangular guide blocks 6. The gas and liquid refrigerants are connected by the liquid pipe 2, enter the upper cavity 11 along the top opening of the columnar structure 12, and flow along the liquid flow channel to the partition 14. The mixed refrigerant contacts the triangular guide blocks 6 during the flow process, and is fully mixed after multiple separations of the triangular guide blocks 6.

[0020] The outer edge of the partition 14 is provided with a plurality of leakage holes 15 in a ring shape, which connect the upper cavity 11 and the lower cavity 13. The leakage holes 15 are provided on the partition 14 in the area between the side wall of the cone 3 and the inner wall of the upper cavity 11. The fully mixed refrigerant flows along the leakage holes 15 on the partition 14 to the lower cavity 13.

[0021] The lower cavity 13 is cylindrical, and a circular plate 4 is horizontally arranged in the lower cavity 13. A plurality of liquid outlet holes are evenly arranged on the circular plate 4. In this embodiment, four liquid outlet holes are arranged, and each liquid outlet hole is respectively connected and communicated with a diversion pipe 5, and the other end of the diversion pipe 5 extends out of the side wall of the lower cavity 13.

[0022] It should also be noted that the upper end of the cone 3 extends into the liquid pipe 2 toward the opening, and the lower end of the liquid pipe 2 is tapered, forming an inverted cone. A certain gap is provided between the inner wall of the lower end of the liquid pipe 2 and the outer wall extending from the top of the cone 3 to allow the mixed refrigerant to flow in. The top opening of the columnar structure 12 is the same shape as the tapered end of the lower end of the liquid pipe 2, and the two are sealed together. Specifically, the liquid pipe 2 and the columnar structure 12 are connected by a rotary seal. The inner ring of the end of the liquid pipe 2 away from the columnar structure 12 is provided with an internal thread, and the liquid pipe 2 is mounted on the refrigerant supply device via the internal thread. The portion of the liquid pipe 2 extending into the columnar structure 12 forms a tapered end, which can increase the flow rate of the gaseous and liquid refrigerants entering.

[0023] After the gas and liquid refrigerants enter along the liquid pipe 2, their flow velocity is increased by the constriction, so that they quickly enter the columnar structure 12 and contact the upper end of the frustum 3. The conical structure at the end of the frustum 3 disperses the gas and liquid refrigerants and flows along its surface and enters the liquid flow channel. In this way, the first uniform distribution at the end of the frustum 3 and the second uniform distribution in the liquid flow channel enable the gas and liquid refrigerants to be fully mixed and flow to the leakage hole 15, and finally flow out evenly along the diversion pipe 5, thereby achieving uniform distribution of the refrigerant.

[0024] The above-described embodiments merely represent preferred embodiments of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications, improvements, and substitutions without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
