[0002] Currently, the evaporator structure in the refrigeration equipment with patent number ZL202410554314.X typically has the following shortcomings: Welding process defects: Some evaporators use a split refrigerant piping design, which requires manual welding to connect the components. This poses a risk of leakage at the welds, affecting refrigeration efficiency and increasing maintenance costs.

[0003] Limitations in heat exchange efficiency: Refrigerant pipes are mostly spiral wound structures, resulting in slow fluid flow rates and insufficient vaporization of condensed liquid, leading to low heat transfer efficiency.

[0004] Material and structural limitations: The evaporator shell is not made of high thermal conductivity aluminum and lacks a paintable surface treatment process, making it difficult to meet diverse appearance requirements; at the same time, the structure does not include motor bearings and stirring components, making it impossible to actively stir the raw materials in the refrigerant zone, resulting in insufficient cooling uniformity.

[0005] Cost and assembly issues: The split design and complex aerodynamic structures (such as aerodynamic spirals and protruding parts) increase the number of parts and assembly difficulty, resulting in higher production costs. Utility Model Content

Multiple U-shaped channels are arranged inside the vacuum covers, and every two refrigerant pipes correspond to the U-shaped channels. Multiple refrigerant pipes and multiple U-shaped channels form a serpentine channel that surrounds the inner shell of the refrigerant housing for cooling. The U-shaped pipes are connected to the gas guide pipes. The inlet end of the refrigerant pipeline is connected to the condenser via a condenser inlet pipeline, and the outlet end of the refrigerant pipeline is connected to the compressor via a gas duct.

[0007] Preferably, the vacuum cover is provided with multiple protrusions, and the refrigerant shell has grooves corresponding to the protrusions for connection.

[0014] Preferably, the gas duct and condensate input pipe are made of copper, the refrigerant shell and vacuum cover are made of copper or aluminum, and the motor bearing is made of plastic with silicone.

[0015] Preferably, the outer shell of the evaporator is provided with multiple connection holes, which are used to connect the outer shell of the evaporator to the equipment.

[0016] The beneficial effects of this utility model are: Integrated design enhances reliability: The refrigerant pipes and refrigerant housing are manufactured using an integrated molding process, eliminating the need for manual welding, completely avoiding the risk of welding leaks, and improving equipment sealing and service life.

[0017] The serpentine channel optimizes flow rate and cooling: the serpentine structure formed by the refrigerant pipe and the U-shaped channel results in a faster fluid flow rate compared to spiral winding. The condensed liquid can vaporize and absorb heat more efficiently, and the heat transfer efficiency is significantly improved.

[0018] Aluminum Material and Paintability: The outer shell of the evaporator is made of aluminum, which not only has excellent thermal conductivity, but can also be directly painted to meet the diverse appearance requirements of the equipment, while enhancing corrosion resistance.

[0019] Motor bearing driven stirring function: The motor bearing passes through the outer shell of the evaporator tank and connects to the vacuum cover. It can be used to install a motor and stirring rod to actively stir the raw materials in the refrigerant zone, ensuring that the raw materials and refrigerant are in full contact, achieving uniform cooling and avoiding local temperature differences.

[0020] Spiral winding structure for buffered cooling: The tail end of the condensate input pipe is spirally wound around the tail end of the air guide pipe.

[0027] like Figures 1-5As shown, this utility model embodiment provides an integrated inner cavity surround type evaporative refrigeration device, including a refrigerant shell 1, a plurality of refrigerant pipes 2 are provided on the upper part of the refrigerant shell 1, a vacuum cover 3 is provided at the head and bottom of the refrigerant shell 1, and a plurality of U-shaped channels 4 are provided inside the vacuum cover 3, with each pair of refrigerant pipes corresponding to the U-shaped channel 4. Multiple refrigerant pipes 2 and multiple U-shaped channels 4 form a serpentine channel that surrounds the inner shell of the refrigerant shell 1 to cool it; The inlet of the refrigerant pipeline is connected to the condenser via the condenser inlet pipeline 5, and the outlet of the refrigerant pipeline is connected to the compressor via the gas duct 6.

[0028] In this embodiment, the vacuum cover 3 is provided with a plurality of protrusions 7, and the refrigerant shell 1 has grooves 8 corresponding to the protrusions 7 for connection.

[0029] In this embodiment, the refrigerant shell 1 and the refrigerant pipe 2 are designed as a single unit.

[0030] In this embodiment, the opening and outlet of the refrigerant pipe 2 are polygonal or geometrically shaped.

[0031] In this embodiment, the interior of the refrigerant housing 1 is provided with an input port 9 and an output port 10 that are connected to the refrigerant pipe 2 in a one-to-one correspondence.

[0032] In this embodiment, the tail end of the condensate input pipe 5 is spirally wound around the tail end of the air guide pipe 6.

[0033] In this embodiment, the refrigerant housing 1 is externally connected to an evaporator shell 11, which is made of aluminum.

[0034] In this embodiment, a motor bearing 12 is connected to the bottom of the evaporator shell 11, and the motor bearing 12 passes through the evaporator shell 11 and is connected to an external stirring rod.

[0035] In this embodiment, the gas duct 6 and the condensate input pipe 5 are made of copper, the refrigerant shell 1 and the vacuum cover 3 are made of copper or aluminum, and the motor bearing 12 is made of plastic with silicone.

[0036] In this embodiment, the outer shell 11 of the evaporator is provided with a plurality of connection holes 13, and the outer shell 11 of the evaporator is used to connect to the equipment through the connection holes 13.

[0037] Working principle: Refrigerant circulation start-up: The condenser delivers low-temperature condensed liquid to the inlet 9 of the refrigerant shell 1 through the condenser inlet pipe 5. The liquid flows around in a serpentine channel (composed of refrigerant pipe 2 and U-shaped channel 4) and exchanges heat with the inner wall of the refrigerant shell 1.

[0038] Serpentine channel cooling: The serpentine structure allows the condensed liquid to pass through the refrigerant shell 1 at a faster flow rate. After vaporization and heat absorption, it forms gas, which is then output to the compressor through the gas guide pipe 6 to complete the refrigeration cycle. At the same time, the tail of the condensate input pipe 5 is wrapped around the tail of the gas guide pipe 6, which reduces the gas flow rate through heat exchange and promotes the full vaporization of the condensed liquid.

[0039] Synergistic mixing and heat dissipation: The motor bearing 12 drives the stirring rod to rotate, uniformly stirring the raw materials in the refrigerant zone, ensuring full contact between the raw materials and the refrigerant shell 1, and improving cooling uniformity; the aluminum evaporator shell 11 quickly conducts heat, and the surface paint layer can assist in heat dissipation, further optimizing refrigeration efficiency.

[0040] Continuous operation in a cycle: The compressor compresses the gas output from the gas pipe 6 and sends it back to the condenser, repeating the above condensation-vaporization process to achieve continuous cooling. At the same time, the motor bearing 12 drives the stirring rod to keep the raw materials cooled evenly.

[0041] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
