Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of smart home technology, and in particular to an evaporator and a refrigeration device. Background Art
[0002] The evaporator can achieve a refrigeration effect by utilizing the heat absorption of the medium fluid during the process of converting from liquid to gas. When the evaporator is used in refrigeration equipment, it can bring the surrounding cold air into each room to achieve refrigeration.
[0003] However, due to the low surface temperature of the evaporator, the circulation of hot air will continuously form a frost layer on the evaporator surface. Once the frost layer accumulates and forms a frost blockage, air circulation cannot be performed, which seriously affects the cooling effect of the refrigeration equipment. Utility Model Content

[0026] The evaporator can achieve the cooling effect by utilizing the heat absorption of the medium fluid during the conversion from liquid to gas. When the evaporator is used in refrigeration equipment, it can bring the surrounding cold air into each room to achieve cooling. However, due to the low surface temperature of the evaporator, the circulation of hot air will continuously form a frost layer on the evaporator surface. When the frost layer accumulates and forms frost blockage, air circulation cannot be performed, which seriously affects the cooling effect of the refrigeration equipment.
[0027] The present disclosure provides an evaporator. Figure 1 is a schematic diagram of the structure of an evaporator in an exemplary embodiment of the present disclosure, such as Figure 1 As shown, the evaporator 1 includes a functional body 11 and a magnetic field generating device 12, the functional body 11 includes at least one medium pipeline 111, and the magnetic field generating device 12 is arranged outside the medium pipeline 111. When the magnetic field generating device 12 is working, the magnetic field formed by the magnetic field generating device 12 magnetizes at least a part of the water in the air outside the medium pipeline 111.
[0028] Since the evaporator 1 includes a magnetic field generating device 12 disposed outside the medium pipeline 111, when the magnetic field generating device 12 is working, the magnetic field formed by the magnetic field generating device 12 magnetizes at least a portion of the water in the air outside the medium pipeline 111. After the water in the air outside the medium pipeline 111 is magnetized, the ice crystal size is reduced, and the magnetic field force also causes the Gibbs free energy to decrease, so that the ice nucleus radius decreases with the phase change driving force and the ice nucleus increase rate decreases. That is, under the same frosting time, the surface of the medium pipeline 111 of the evaporator 1 is less frosted under the action of the magnetic field, which has the effect of actively inhibiting frost formation, thereby helping to improve the service life and refrigeration effect of the evaporator 1.
[0029] Based on the special molecular structure of water, the water in the air outside the medium pipeline 111 is easily magnetized in the magnetic field. The physical properties of magnetized water such as heat capacity, self-diffusion coefficient, viscosity, and surface tension are affected by the intensity of the magnetic field. The magnetic field affects the aggregation and size change of water droplets, making the ice crystal size smaller under the action of the magnetic field. Under the same frosting time, the water droplet size is smaller under the action of the magnetic field. At the same time, the greater the magnetic field intensity, the smaller the water droplets, and the more uniform the morphology of the water droplets. In addition, the magnetic field force causes the Gibbs free energy to decrease, reducing the driving force of the phase change, making the ice nucleus radius smaller and the ice nucleus increase rate smaller. Under the same frosting time, the surface of the evaporator 1 is less frosted under the action of the magnetic field, and the frost blockage time increases significantly with the increase of the magnetic field intensity.
[0030] It should be noted that the outer wall of the medium pipe 111 may be provided with fins 112 to improve the heat exchange efficiency and the refrigeration effect. Alternatively, the medium pipe 111 may be arranged inside the fins 112 to further increase the heat exchange efficiency. The present disclosure can solve the problem of frost on the surface of the medium pipe 111 and the fins 112 through the above solution.
[0031] In some embodiments, the magnetic field generating device 12 is disposed at the periphery of the functional body 11 to reduce structural interference with the medium pipeline 111 or other components of the functional body 11. The magnetic field generated by the magnetic field generating device 12 located at the periphery of the functional body 11 is convenient for covering the entire area of the functional body 11, thereby increasing the magnetization ratio of water in the air at the periphery of the medium flow channel.
[0032] For example, the evaporator 1 may further include a shell 21 disposed on the periphery of the functional body 11, and the magnetic field generating device 12 is assembled in the shell 21. The magnetic field generating device 12 is disposed on the outer shell of the functional body 11 to ensure structural stability and facilitate adjustment of the magnetic field coverage, which helps to improve the magnetization ratio of water in the air outside the medium flow channel and the controllability of other magnetization parameters.
[0033] In other embodiments, the magnetic field generating device 12 may be disposed inside the functional body 11 to magnetize water in the air outside the medium pipe 111 by using the magnetic field formed by the magnetic field generating device 12. For example, the medium pipe 111 is bent and coiled inside the functional body 11, and the magnetic field generating device 12 may be disposed in the interval formed by the coiling of the medium pipe 111 to reduce the space occupied at other positions of the functional body 11.
[0034] In some embodiments, the shell 21 may include an inner surface facing the functional body 11 and an outer surface opposite to the inner surface, and the magnetic field generating device 12 is arranged on the outer surface to enhance the setting flexibility of the magnetic field generating device 12 and facilitate the formation of the required magnetic field.
[0035] Among them, Figure 2 As shown, the shell 21 can be the device shell 13 of the evaporator 1 itself, or can be the inner shell of the refrigeration device located outside the functional body 11 of the evaporator 1. When the shell 21 is the inner shell of the refrigeration device, the magnetic field generating device 12 can be arranged on the outer surface of the inner shell facing the refrigeration chamber of the refrigeration device to facilitate disassembly, assembly, adjustment and control. The magnetic field generating device 12 can also be arranged on the inner surface of the inner shell facing the evaporator 1 to reduce the impact on the appearance of the refrigeration chamber of the refrigeration device.
[0036] In some embodiments, the housing 21 includes a first side wall 211 and a second side wall 212 that are arranged opposite to each other, and the first side wall 211 and the second side wall 212 are respectively assembled with a magnetic field generating device 12. By arranging the magnetic field generating device 12 on the opposite side walls of the housing 21, the magnetic pole relationship formed by the magnetic field generating device 12 at the relative position can be utilized to make the magnetic field cover the area between the first side wall 211 and the second side wall 212, thereby improving the magnetic field coverage area and the controllability of the magnetic field parameters.
[0037] For example, the magnetic pole of the magnetic field generating device 12 located on the first side wall 211 facing the second side wall 212 can be set to the N pole, and the magnetic pole of the magnetic field generating device 12 located on the second side wall 212 facing the first side wall 211 can be set to the S pole, and a magnetic field pointing from the S pole to the N pole is formed between the N pole and the S pole, and the magnetic field covers the space between the first side wall 211 and the second side wall 212, so that the water in the air outside the medium pipeline 111 between the first side wall 211 and the second side wall 212 is magnetized, and the magnetic field strength is controllable.
[0038] In the above embodiment, the projection of the magnetic field generating device 12 in the direction from the first side wall 211 to the second side wall 212 covers the medium pipe 111, so that the magnetic field formed by the magnetic field generating device 12 can cover the air outside the medium pipe 111 to the greatest extent, thereby improving the magnetization ratio and effect of water in the air.
[0039] In some embodiments, the evaporator 1 further includes a heating device 14, which is disposed on one side of the functional body 11, and a preset interval is provided between the heating device 14 and the functional body 11 to avoid structural and functional interference and damage caused by direct contact with the functional body 11. The frost on the surface of the medium pipe 111 of the evaporator 1 can be melted by the heating device 14, and the water vapor around the magnetized medium pipe 111 can be used to extend the frost formation time by defrosting, thereby reducing the difficulty of defrosting the evaporator 1, and improving the defrosting effect and the service life of the evaporator 1.
[0040] In the above embodiment, Figure 1 The dashed arrow in the middle may indicate the direction of gravity. In the direction of gravity, the heating device 14 is located at the bottom of the functional body 11 to heat the medium pipeline 111 by floating the heat from the bottom, thereby improving the heating and defrosting efficiency.
[0041] It should be noted that the magnetic field generating device 12 includes a magnet or an electromagnet. When the magnetic field generating device 12 is a magnet, the cost can be reduced and the assembly is convenient. When the magnetic field generating device 12 is an electromagnet, the working parameters of the electromagnet can be controlled and adjusted, thereby adjusting the magnetization parameters of the water in the air outside the medium pipeline 111, thereby improving the intelligence of use.
[0042] In addition, the fluid medium in the medium pipeline 111 may be water, a solution, or a refrigerant, which is not limited in the present disclosure.
[0043] The present disclosure further provides a refrigeration device, which includes the evaporator 1 mentioned above.
[0044] Since the evaporator 1 of the refrigeration equipment includes a magnetic field generating device 12 disposed outside the medium pipeline 111, when the magnetic field generating device 12 is working, the magnetic field formed by the magnetic field generating device 12 magnetizes at least a portion of the water in the air outside the medium pipeline 111. After the water in the air outside the medium pipeline 111 is magnetized, the ice crystal size is reduced, and the magnetic field force also causes the Gibbs free energy to decrease, so that the radius of the ice nucleus decreases with the phase change driving force and the ice nucleus increase rate decreases. That is, under the same frosting time, the surface of the medium pipeline 111 of the evaporator 1 is less frosted under the action of the magnetic field, which has the effect of actively inhibiting frost formation, thereby helping to improve the service life and refrigeration effect of the evaporator 1.
[0045] It should be noted that the above-mentioned refrigeration equipment can be a refrigerator, a freezer, a refrigerator, an evaporative cooling tower, etc., and the present disclosure is not limited to the type of refrigeration equipment.
[0046] The above is only a preferred embodiment of the present disclosure and does not limit the present disclosure in any form. Although the present disclosure has been disclosed as a preferred embodiment as above, it is not used to limit the present disclosure. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present disclosure. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present disclosure without departing from the content of the technical solution of the present disclosure are still within the scope of the technical solution of the present disclosure.
