As shown in fig. 1, the present application provides a refrigerating apparatus including a cabinet 100, an evaporator 200, and an air return pipe 300. It should be noted that, the refrigeration equipment in the present application may be a refrigerator, a fresh-keeping cabinet, etc., and the evaporation pipe in the refrigeration equipment is connected with the muffler 300, and a method of welding the evaporator 200 and the muffler 300 on line is adopted, and then the welded evaporator 200 and the muffler 300 are installed in the accommodating space behind the vertical beam 101 of the box 100. When the evaporator 200 body or the welding position of the evaporator 200 and the muffler 300 is leaked, the evaporator 200 needs to be replaced for repair, at this time, a serviceman needs to detach the vertical beam 101, and then extend into the accommodating space by using a tool to repair the welding position of the evaporator 200 and the muffler 300.

Specifically, as shown in fig. 1, 2 and 6, the case 100 has a plurality of refrigerating compartments 103 therein, and the case 100 includes a vertical beam 101 and a side wall 102, the vertical beam 101 being disposed opposite to the side wall 102, for example, the vertical beam 101 and the side wall 102 may be disposed in parallel. The evaporator 200 is arranged between the side wall 102 and the vertical beam 101, and the cold of the evaporator 200 can flow to the plurality of refrigeration compartments 103, so that the energy consumption caused by independent refrigeration is avoided, and the overall refrigeration efficiency of the refrigeration equipment is improved.

The part of the structure of the air return pipe 300 connected and communicated with the evaporator 200 is parallel to the plane where the evaporator 200 is positioned, the vertical distance from the side wall 102 to the vertical beam 101 is H1, the vertical distance from the connecting point of the air return pipe 300 and the evaporator 200 to the side wall 102 is H2, and the ratio of H2 to H1 is more than or equal to 35%. It should be noted that, the vertical beam 101 is closer to the user, that is, the connection point of the muffler 300 and the evaporator 200 is closer to the user, so that when a leak occurs at the connection point of the evaporator 200 and the muffler 300, the user or a maintenance person can be closer to the connection point of the muffler 300 and the evaporator 200, thereby facilitating maintenance.

According to the refrigeration equipment of the embodiment of the application, the muffler 300 is connected and communicated with the evaporator 200, and the position of the connection point of the muffler 300 and the evaporator 200 is defined, so that the ratio of the vertical distance H1 from the side wall 102 to the vertical beam 101 to the vertical distance H2 from the connection point of the muffler 300 and the evaporator 200 to the side wall 102 is greater than or equal to 35%. Like this, if leak appears in the junction of evaporimeter 200 and muffler 300, when returning the maintenance of factory with evaporimeter 200, because shortened the perpendicular distance of the junction of evaporimeter 200 and muffler 300 and vertical beam 101, make things convenient for the maintenance personal to maintain the tie point of muffler 300 and evaporimeter 200, promoted the convenience of maintenance.

As shown in fig. 3 and 4, in some embodiments of the present application, the evaporator 200 is integrally provided with the muffler 300. In this way, the time for transferring the refrigerant between the evaporator 200 and the muffler 300 can be reduced, the refrigerant can be utilized more rapidly and efficiently, and the cooling efficiency of the refrigeration apparatus can be improved. The integrated design also reduces additional interfaces, avoids leakage of refrigerant at the interfaces or blockage of the muffler 300, and increases the stability of the system. In addition, by integrating the evaporator 200 and the muffler 300, the installation process and time of the evaporator 200 and the muffler 300 can be simplified, the complexity of installation can be reduced, the need for manual installation and maintenance can be reduced, and the production and maintenance costs can be greatly reduced. The integrated design reduces the complexity and footprint of the system, making the overall refrigeration system more compact.

In some embodiments of the application, as shown in fig. 3, the evaporator 200 is welded to the muffler 300. The welding may provide higher connection strength and good sealing performance for the evaporator 200 and the muffler 300, preventing leakage of the refrigerant. The welded connection also has durability, so that the evaporator 200 and the muffler 300 can be used for a long time, the loosening condition of the muffler 300 or the evaporator 200 is reduced, the muffler 300 is blocked, and the muffler 300 or the evaporator 200 is frequently replaced or repaired, thereby improving the efficiency and the safety performance of the refrigerating system.

In some examples, the evaporator 200 and the muffler 300 may be welded off-line of the production line, the welded evaporator 200 and the muffler 300 may form an integral module, and then transported to the production line, and the welded evaporator 200 and the muffler 300 integral module may be integrally assembled. It should be noted that, under the line of the production line, the evaporator 200 and the muffler 300 are welded together, which belongs to a static welding process; the evaporator 200 and the muffler 300 are welded together on the line of the production line, belonging to the dynamic welding process; compared with dynamic welding, the static welding process is easier to realize, the welding seam structure strength is stronger, and the welding yield is higher.

As shown in fig. 3 and fig. 4, in some embodiments of the present application, the muffler 300 includes a first section 301 and a second section 302, where a plane of the first section 301 is parallel to a plane of the evaporator 200, and since the first section 301 is parallel to the plane of the evaporator 200, a flow path of a refrigerant in the evaporator 200 when the refrigerant enters the muffler 300 is regular, which is beneficial to flow of the refrigerant and improves refrigeration efficiency. And one end of the first section 301 is connected and communicated with the outlet of the evaporator 200, the other end of the first section 301 is connected and communicated with one end of the second section 302, and the other end of the second section 302 is connected and communicated with the air return port of the compressor.

As shown in fig. 3 and 4, in some embodiments of the application, the second section 302 meanders, for example, the second section 302 may meander in a U-shape, or in other embodiments, the second section 302 may meander in an S-shape. Or in other embodiments the first segment 301 may extend along a straight line. The second section 302 may be disposed adjacent to the capillary heat exchange tube, and by providing the second section 302 in a serpentine shape, the capillary heat exchange tube may be substantially heat exchanged with the second section 302.

The serpentine extending second segment 302 of the muffler 300 expands the flow area of the refrigerant, so that the refrigerant can be better dispersed when flowing through the entire system, and the evaporation and condensation efficiency is improved. The serpentine shape also has an effect of suppressing the coolant flow velocity from being too fast, and avoids insufficient condensation caused by too fast coolant flow. Meanwhile, the design that the first section 301 extends along a straight line can reduce the distance between the refrigerant from the evaporator 200 and the muffler 300, so that the pressure loss caused by the overlong distance during the flow of the refrigerant can be reduced, and the working efficiency of the refrigeration system can be further improved.

As shown in fig. 3, in some embodiments of the present application, the plane of the second section 302 is parallel to the side wall 102, and the second section 302 is attached to the side wall 102, so that the space of the refrigeration device can be utilized to the maximum extent, and the muffler 300 can be better hidden in the structure of the case 100, so that the space occupation inside the case 100 is reduced, and a larger storage space is realized for the case 100. Meanwhile, the design is also beneficial to improving the efficiency of the internal circulation of the refrigerant in the refrigeration equipment and improving the cooling effect of the refrigeration equipment.

In some embodiments of the present application, the sidewall 102 is provided with a receiving groove (not shown), the shape of the receiving groove is adapted to the shape of the second section 302, and the second section 302 is disposed in the receiving groove. Therefore, the space inside the refrigeration equipment can be further saved, more storage space is increased, and the appearance of the refrigeration equipment is tidier and more attractive. At the same time, the adaptive design of the shape of the receiving groove and the shape of the second section 302 makes the muffler 300 more stable, reducing potential damage caused by vibration or movement of the refrigeration equipment. In addition, the second section 302 is contained in the containing groove, so that dust and dirt can be prevented, and cleaning and maintenance of the refrigeration equipment are facilitated. By the design, the practicability of the refrigeration equipment is improved, and the durability and the stability of the refrigeration equipment are also enhanced.

The heat exchange coil 201 meanders, and the heat exchange coil 201 is connected and communicates with the return air duct 300. In this way, the serpentine design allows the heat exchange coil 201 to provide a larger heat exchange area in a limited space for more efficient heat exchange. The serpentine coil lengthens the refrigerant flow path, thereby increasing the residence time of the refrigerant in the coil and facilitating the improvement of heat exchange efficiency. The serpentine design allows for a more uniform distribution of heat throughout the heat exchange coil 201, thereby improving the overall system heat dissipation efficiency.

The heat radiation fins 202 are provided on the outer peripheral wall of the heat exchange coil 201. In this way, the heat exchange coil 201 and the heat dissipation fins 202 are integrally designed to be closely matched, so that cold air is quickly transferred to each heat dissipation fin 202, the heat dissipation area is further increased, and the heat dissipation efficiency is improved. The heat radiating fins 202 are directly arranged on the outer side of the heat exchanging coil 201, so that space can be saved, heat conduction efficiency of the heat exchanging coil 201 and the heat radiating fins 202 can be guaranteed, and a more compact and efficient design of the evaporator 200 is realized. The heat radiating fins 202 and the heat exchanging coil 201 are directly combined, so that the stability of the whole structure of the evaporator 200 can be enhanced, and equipment damage caused by vibration or impact in the operation process is avoided.
