Technical Field
[0001] This utility model relates to the field of finned evaporators, specifically an antifreeze finned evaporator. Background Technology
[0002] Finned evaporators, also known as finned evaporators or finned tube heat exchangers, are widely used heat exchange equipment. Under low temperature or high humidity conditions, the surface of the finned heat exchange tubes is prone to frost formation, and electric defrosting devices are usually required to clean the frost layer on the surface of the finned heat exchange tubes.
[0003] However, existing heating tubes are usually fixed inside the finned evaporator, which means that the finned heat exchange tubes may not be heated evenly, resulting in uneven melting of the frost layer on the finned heat exchange tubes. This may affect the defrosting effect and may even cause the frost layer to be too thick in some areas, affecting the heat exchange efficiency. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, heating tubes are usually fixed inside finned evaporators. This can lead to uneven heating of the finned heat exchange tubes, resulting in uneven melting of frost on the finned heat exchange tubes. This may affect the defrosting effect and may even cause excessive frost in some areas, affecting heat exchange efficiency. This utility model proposes an antifreeze finned evaporator.
[0005] The technical solution adopted by this utility model to solve its technical problem is: an antifreeze finned evaporator, including a shell, a finned heat exchange tube installed in the inner cavity of the shell, and a defrosting mechanism installed on the front and back sides of the inner cavity of the shell.
[0006] The defrosting mechanism includes a motor and a guide groove. The bottom of the motor is fixedly connected to the top of the housing. The guide groove is opened at the bottom of the inner cavity of the housing. A gear is fixedly connected to the output end of the motor. Gear plates are meshed on the front and back sides of the gear surface. A defrosting plate is fixedly connected to the bottom of the gear plate. A heating tube is fixedly connected to the inner cavity of the defrosting plate. There are multiple heating tubes arranged in multiple rows.
[0007] Preferably, a support rod is movably connected to the inner cavity of the toothed plate, and the surface of the support rod is fixedly connected to the inner cavity of the housing.
[0008] Preferably, the inner cavity of the guide groove is movably connected to a guide plate, and the top of the guide plate is fixedly connected to the bottom of the defrost plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0023] This application discloses an antifreeze finned evaporator. (Refer to...) Figure 1 , Figure 2 and Figure 3 An antifreeze finned evaporator includes a shell 1, a finned heat exchange tube 3 installed in the inner cavity of the shell 1, and a defrosting mechanism 2 installed on the front and back sides of the inner cavity of the shell 1.
[0024] The defrosting mechanism 2 includes a motor 201 and a guide groove 208. The bottom of the motor 201 is fixedly connected to the top of the housing 1. The guide groove 208 is opened at the bottom of the inner cavity of the housing 1. A gear 206 is fixedly connected to the output end of the motor 201. A toothed plate 205 is meshed with the front and back sides of the surface of the gear 206. A defrosting plate 202 is fixedly connected to the bottom of the toothed plate 205. A heating tube 204 is fixedly connected to the inner cavity of the defrosting plate 202. There are multiple heating tubes 204 arranged in multiple rows.
[0025] Reference Figure 3 A support rod 207 is movably connected to the inner cavity of the toothed plate 205. The surface of the support rod 207 is fixedly connected to the inner cavity of the housing 1. The support rod 207 provides support for the toothed plate 205, improves the stability of the toothed plate 205 during movement, and prevents the toothed plate 205 from disengaging from the surface of the gear 206 during movement.
[0026] Reference Figure 3The inner cavity of the guide groove 208 is movably connected to the guide plate 203. The top of the guide plate 203 is fixedly connected to the bottom of the defrost plate 202. Through the setting of the guide groove 208, the guide plate 203 can slide in the inner cavity of the housing 1. Thus, the setting of the guide plate 203 guides the movement of the defrost plate 202 and prevents the top and bottom of the defrost plate 202 from being out of sync during the movement.
[0027] Reference Figure 2 and Figure 3 A collection mechanism 4 is installed at the bottom of the inner cavity of the shell 1. The collection mechanism 4 includes a connecting groove 403. A connecting plate 401 is movably connected to the inner cavity of the connecting groove 403. A collection box 402 is fixedly connected to the top of the connecting plate 401. The collection box 402 is located at the bottom of the finned heat exchange tube 3. By setting the collection box 402, water droplets generated after defrosting the surface of the finned heat exchange tube 3 are collected to prevent water droplets from accumulating inside the shell 1 and causing pollution to the internal environment of the shell 1.
[0028] Reference Figure 3 and Figure 4 The connecting groove 403 has mounting grooves 404 on both the front and back sides of its inner cavity. An elastic clip 406 is fixedly connected to the inner cavity of the mounting groove 404. The connecting plate 401 has fixing slots 408 on both the front and back sides of its inner cavity. The surface of the elastic clip 406 engages with the inner cavity of the fixing slot 408. By setting the elastic clip 406, when its surface engages with the inside of the fixing slot 408, the position of the connecting plate 401 can be fixed, so that it can stably support the collection box 402.
[0029] Reference Figure 4 The bottom of the inner cavity of the connecting plate 401 is provided with a groove 407, and a handle 405 is fixedly connected to the inner cavity of the groove 407. The handle 405 increases the contact area between the operator and the connecting plate 401, thereby making it easier to move the position of the connecting plate 401 by using the handle 405.
[0030] Reference Figure 4 An anti-slip sleeve 409 is fixedly connected to the surface of the grip 405. The anti-slip sleeve 409 is made of silicone. The anti-slip sleeve 409 increases the friction between the hand and the grip 405 during contact, thereby preventing the hand from slipping during the movement of the grip 405.
[0031] Working principle: After the frost layer on the surface of the finned heat exchanger tube 3 accumulates to a certain extent, the motor 201 is started by an external power supply. The motor 201 drives the gear 206 to rotate, which in turn drives the toothed plate 205 to move. The movement of the toothed plate 205 drives the defrosting plate 202 to move, which in turn drives the heating tube 204 to reciprocate inside the shell 1. This allows the heating tube 204 to clean the frost layer on the surface of the finned heat exchanger tube 3, preventing the frost layer from becoming too thick and affecting the heat exchange efficiency of the finned heat exchanger tube 3. The frost water generated after the frost layer melts will drip down. After the frost layer on the surface of the finned heat exchange tube 3 is cleaned, the frost water collected inside the collection box 402 is removed by holding the anti-slip sleeve 409 and pulling it down. The movement of the anti-slip sleeve 409 moves the handle 405, which in turn moves the connecting plate 401. During the process of the connecting plate 401 being subjected to force, the elastic clip 406 will disengage from the inside of the fixing slot 408, so that the connecting plate 401 can be taken out from the inside of the connecting slot 403. The movement of the connecting plate 401 moves the collection box 402, so that the collection box 402 can be taken out from the inside of the shell 1 and the frost water collected inside the collection box 402 can be cleaned.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
