Abstract
Description
Technical Field
[0001] This utility model relates to a structure that accelerates the cooling rate of the internal environment of a cavity and enhances temperature uniformity. Background Technology
[0002] Existing systems have low requirements for temperature uniformity within the container or cavity, and most do not require it. However, with technological advancements, demands for both temperature control and uniformity are increasing. Therefore, structures are needed that can achieve temperature uniformity throughout the entire cavity while also accelerating the cooling rate.
[0003] The existing technology CN103851852B, a refrigerator air supply system, refrigerator and air supply method patent, is insufficient in that the structure can only meet the temperature uniformity within its own space, and the placement of materials will affect the airflow circulation, causing a decrease in temperature uniformity.
[0004] Therefore, a structure is proposed to address the above problems by accelerating the cooling rate of the cavity environment and enhancing temperature uniformity. Utility Model Content
[0005] The purpose of this invention is to overcome the existing defects and provide a structure that accelerates the cooling rate of the cavity environment and enhances the temperature uniformity, thereby accelerating the temperature drop rate within the cavity and enhancing the temperature uniformity within the cavity.
[0006] The technical solution to achieve the above objective is: a structure that accelerates the cooling rate of the internal environment and enhances temperature uniformity, comprising a box body, blades connected to the inner side wall of the box body, a shelf connected to the inner side wall of the box body, an evaporation plate connected to the bottom surface of the box body, the blades located above the shelf, a guide plate connected to the lower end surface of the shelf, and a door connected to the front end of the box body.
[0007] Preferably, there can be multiple blades.
[0008] Preferably, the blade is connected to a variable frequency motor.
[0009] Preferably, the outer wall of the box is provided with a heat insulation layer.
[0010] Preferably, a blade cover is provided on the outer side of the blade.
[0011] Preferably, the evaporator plate is connected to a refrigerant delivery pipe.
[0012] Preferably, the number of guide plates is multiple, and they are connected at equal intervals to the lower end surface of the shelf.
[0013] The beneficial effects of this invention are as follows: This structure, which accelerates the cooling rate of the internal environment and enhances temperature uniformity, is achieved by connecting blades to the inner wall of the chamber, a shelf to the inner wall of the chamber, and an evaporator plate to the bottom of the chamber. The blades are positioned above the shelf, and a guide plate is provided on the front side wall of the blades. When the blades rotate, they draw in air from above the shelf, send the drawn-in air below the blade cover, and then move it along the guide plate through the evaporator plate after cooling towards the chamber door. It is then further moved to the shelf, forming a complete cycle. With numerous cycles, the cooling rate during the cooling phase is accelerated, and the temperature uniformity throughout the chamber is improved during the constant temperature phase. This simple method accelerates the temperature drop rate within the chamber and enhances temperature uniformity within the chamber. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0019] The present invention will be further described below with reference to the accompanying drawings.
[0020] like Figure 1-3As shown, a structure for accelerating the cooling rate and enhancing temperature uniformity within a cavity includes a housing 5. Multiple blades 3 are connected to the inner wall of the housing 5. Each blade 3 is connected to a variable frequency motor. A blade cover 6 is provided on the outer side of each blade 3. A shelf 7 is connected to the inner wall of the housing 5, and an evaporator plate 9 is connected to the bottom surface of the housing 5. A refrigerant delivery pipe 4 is connected to the evaporator plate 9. The blades 3 are positioned above the shelf 7, and multiple guide plates 8 are connected to the lower surface of the shelf 7 at equal intervals. A door 2 is connected to the front end of the housing 5. An insulation layer 1 is provided on the outer wall of the housing 5.
[0021] Specifically, the evaporator plate 9 is used to cool the cavity; the blades 3 are used to agitate the airflow within the cavity; the evaporator plate 9 can be cooled using refrigerants such as Freon or liquid nitrogen. The blades 3 are connected to a motor, and the agitation capability of the blades is controlled by adjusting the motor frequency. The housing 5, the door 2, the shelf 7, and the guide plate 8 form a circulating flow channel.
[0022] Specifically, in the evaporator plate 9, refrigerant Freon or liquid nitrogen is introduced through the refrigerant delivery pipe 4, activating the variable frequency motor that drives the blades 3 to rotate, placing the materials to be frozen on the shelf 7. During operation, as the blades 3 rotate, they draw in air from above the shelf 7, sending the drawn-in air below the blade cover 6. The air then travels along the guide plate 8, passes through the evaporator plate 9, is cooled, and moves towards the door 2, before being further moved to above the shelf 7, forming a complete cycle. With numerous cycles, the cooling rate accelerates during the cooling phase, and the temperature uniformity throughout the chamber improves during the constant temperature phase.
[0023] This structure, which accelerates the cooling rate and enhances temperature uniformity within the chamber, utilizes a configuration where blades 3 are connected to the inner wall of the chamber 5, a shelf 7 is connected to the inner wall of the chamber 5, and an evaporator plate 9 is connected to the bottom surface of the chamber 5. The blades 3 are positioned above the shelf 7, and a guide plate 8 is located on the front wall of the blades 3. When the blades 3 rotate, they draw in air from above the shelf 7, directing the air below the blade cover 6. The air then travels along the guide plate 8, is cooled by the evaporator plate 9, and moves towards the chamber door 2. Finally, it is moved back above the shelf 7, forming a complete cycle. Through numerous cycles, the cooling rate during the cooling phase accelerates, and the temperature uniformity throughout the chamber improves during the constant-temperature phase. This simple method accelerates the rate of temperature decrease within the chamber and simultaneously enhances temperature uniformity within the chamber.
