Description

Technical Field

[0001] This utility model relates to the technical field of dryer-related equipment, and more specifically to a high-efficiency drying heat exchange component for a dryer. Background Technology

[0002] Existing dryer modules generally include a compressor, evaporator, condenser, expansion valve or capillary tube, etc. The evaporator and condenser are installed close to each other. Moist air passes through the evaporator, and the moisture in the air is condensed into water droplets. Then, the air passes through the condenser, and the air is heated into hot air, which is blown into the drying drum to dry the clothes inside. Then, the gas in the drying drum flows back to the evaporator for condensation and dehumidification, realizing circulation. The condensed water droplets accumulate in the collection tank on the shell. This structure is used for drying. However, in use, its main function is drying, meaning the drying effect of the condenser is greater than that of the evaporator. Therefore, the volume of the condenser is generally increased to increase the number of heat exchange tubes inside, thereby improving the drying effect. This increases the volume of the entire heat exchange module, making the dryer larger and preventing it from being placed in some limited spaces, thus affecting its usability. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a high-efficiency drying heat exchange component for a clothes dryer. It can increase the heat exchange area and volume of the condenser without increasing the volume of the condenser and evaporator, thereby increasing the drying effect without increasing the space occupied, so that the size of the clothes dryer does not increase and the space required for its placement does not need to be increased.

[0004] The solution of this utility model to the aforementioned technical problem is: A high-drying heat exchange component for a clothes dryer includes a condenser and an evaporator. The evaporator is located to the left of the condenser. The condenser is provided with four rows of condenser heat exchange tubes arranged in parallel, and the evaporator is provided with three rows of evaporator heat exchange tubes arranged in parallel. The outlet end of the condenser heat exchange tube is connected to the inlet end of the evaporator heat exchange tube through a first U-shaped connecting pipe. The inlet end of the evaporator heat exchange tube is located at the bottom of the evaporator, and a capillary tube is provided at the middle of the rightmost part of the evaporator heat exchange tube.

[0005] The front end of the straight tube extending forward and backward at the bottom of the evaporator heat exchange tube body is the inlet end. The rear end of the straight tube body is connected to the rear end of the straight tube body at the bottom of the rightmost vertical row of S-shaped coiled heat exchange tubes on the right side of the evaporator through a corresponding U-shaped tube. The front ends of the two straight tube bodies in the middle of the right heat exchange tube section are connected by a capillary tube.

[0006] The front ends of the two straight tubes in the middle of the right heat exchange tube section are connected to a bent connecting pipe that extends forward and bends horizontally to the left or right. The ends of the two bent connecting pipes on the same side are connected by a capillary tube.

[0007] The outstanding effect of this utility model is: Compared with existing technologies, it uses the lower part of the right heat exchange tube section on the right side of the evaporator as part of the condenser pipe, thereby increasing the heat exchange area of ​​the entire condenser and improving the drying effect. It does not increase the volume of the condenser and evaporator, nor does it increase the space occupied, so the size of the dryer does not increase and the space required for its placement does not need to be increased.

[0008] Figure 1 This is a partial structural schematic diagram of the present invention; Figure 2 This is a partial structural diagram of the angle-changing part of this utility model; Figure 3 This is a partial front view of the present invention. Detailed Implementation

[0009] For example, see below. Figures 1 to 3 As shown, a high-drying heat exchange component for a clothes dryer includes a condenser 10 and an evaporator 20. The evaporator 20 is located to the left of the condenser 10. The condenser 10 is composed of an S-shaped coiled condenser heat exchange tube 11 and a plurality of heat dissipation fins fixed on the condenser heat exchange tube 11. The evaporator 20 consists of an S-shaped coiled evaporator heat exchange tube body 21 and multiple heat dissipation fins fixed on the evaporator heat exchange tube body 21.

[0010] The condenser heat exchange tubes 11 on the condenser 10 are arranged in four rows of parallel coils, and the evaporator heat exchange tubes 21 on the evaporator 20 are arranged in three rows of parallel coils. A front connecting plate 13 is fixed at the front end of the condenser heat exchange tube body 11 of the condenser 10, and a second front connecting plate 23 is fixed at the front end of the evaporator heat exchange tube body 21 of the evaporator 20. The corresponding sides of the front connecting plate 13 and the second front connecting plate 23 are pressed against each other and fixed by rivets or bolts.

[0011] Furthermore, the outlet end of the condenser heat exchange tube 11 is located at the lower left side of the condenser 10, and it is connected to the inlet end of the evaporator heat exchange tube 21 through the first U-shaped connecting pipe 1. The inlet end of the evaporator heat exchange tube 21 is located at the bottom of the evaporator 20, and a capillary tube 2 is provided at the middle of the rightmost part of the evaporator heat exchange tube 21.

[0012] The front end of the straight tube 211 extending forward and backward at the bottom of the evaporator heat exchange tube 21 extends out of the second front connecting plate 23 at the front end of the evaporator 20, which is the inlet end. The rear end of the straight tube 211 extends out of the last fin and is connected to the rear end of the straight tube 211 at the bottom of the right heat exchange tube section 22, which is a vertical row of S-shaped coils on the right side of the evaporator 20, through a corresponding U-shaped tube. The front ends of the two straight tubes 211 in the middle of the right heat exchange tube section 22 are connected by a capillary tube 2.

[0013] The front ends of the two straight tubes 211 in the middle of the right heat exchange tube section 22 are each connected to a bent connecting tube 212 that extends forward and bends horizontally to the left or right. The ends of the two bent connecting tubes 212 on the same side are connected by a capillary tube 2.

[0014] Furthermore, a temperature sensor mounting tube 3 is welded and fixed to the outer wall of a bent connecting pipe 212, which can fix the temperature sensor in the temperature sensor mounting tube 3.

[0015] In this embodiment, the pipes from the middle to the bottom of the right heat exchange tube section 22 of the evaporator 20 are all used as part of the condenser 10, thereby increasing the entire condensation and drying process. That is, the surface area of ​​the condensation and drying pipes in contact with the gas is increased, improving the condensation and drying effect. The principle is that the refrigerant flowing in the pipes from the middle to the bottom of the right heat exchange tube section 22 and in the condenser heat exchange tube body 11 of the condenser 10 is a high-temperature and high-pressure gas. It exchanges heat with the external flowing gas to dry the gas. At the same time, the refrigerant flowing in the condenser heat exchange tube body 11 becomes a medium-temperature and high-pressure liquid.

[0016] This embodiment changes the ratio of the heat exchange area of ​​condensation and evaporation while keeping the volume of condenser 10 and evaporator 20 unchanged, thereby improving the drying effect. This eliminates the need to increase the volume of condenser 10 and avoids increasing space occupation, thus ensuring that the size of the dryer installed does not increase and that the space required for its placement does not need to be increased.

[0017] 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, and the patent protection scope of the present utility model should be defined by the claims.
