Description

Technical Field

[0001] The utility model mainly relates to the technical field of air-conditioning refrigeration, in particular to an evaporator of an indoor unit of an air-conditioner. Background Art

[0002] Air conditioner evaporator refers to a type of evaporator. Its function is to use the liquid low-temperature refrigerant to evaporate easily under low pressure, turn into steam and absorb the heat of the cooled medium to achieve the purpose of refrigeration. It relies on the fan to force the air in the warehouse to flow through the cooling pipes in the box for heat exchange, so that the air is cooled, thereby achieving the purpose of lowering the warehouse temperature. Among them, the refrigerant or coolant flows in the pipe and cools the air outside the pipe through the pipe wall, which is called a dry air cooler. The one that directly exchanges heat with the air with the sprayed coolant liquid is called a wet air cooler. In addition to the cooling pipe, the hybrid air cooler also has a coolant spray device.

[0003] In this regard, our general household air conditioners basically use dry air coolers, but the air conditioning evaporator in this type of dry air cooler itself cools down slowly. The fundamental reason for its slow cooling is that the indoor air cannot be guided accurately through the drainage to contact the pipes in the evaporator for heat exchange.

[0004] Therefore, an air conditioner indoor evaporator is needed to solve the above problems. Utility Model Content

[0011] Preferably, one end of the second guide plate away from the first guide plate is connected and fixed to one end of the arc-shaped guide plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: by driving the fan driven by a driving motor, indoor air can be quickly brought into the straight tube and the heat sink position, and a channel is formed by the support plate, the first guide plate, the second guide plate and the third guide plate, so that under the drive of the fan, the indoor air enters the channel and contacts the heat sink and the straight tube for cooling, thereby being able to quickly and efficiently guide the indoor air to achieve a rapid cooling effect.

[0013] The first guide plate, the second guide plate and the third guide plate all have cavities, in which water-cooling liquid is arranged. The water-cooling liquid can isolate the straight pipes and heat sinks in the channel, thereby avoiding the loss of cold air and ensuring that the refrigeration effect in the channel will not decrease.

[0022] See also Figure 1-3 An air conditioner indoor evaporator includes a heat exchange tube 1, which includes a plurality of straight tubes 12. Both ends of the plurality of straight tubes 12 are connected through a connecting tube 11. The straight tubes 12 are connected to the connecting tube 11 through the connecting tube 1, and the straight tubes 11 are distributed close to each other, so that the refrigerant can be better exerted. The two straight tubes 12 located at the edge are respectively connected to the liquid inlet pipe 2 and the air outlet pipe 3. The straight tubes 12 and the connecting tubes 11 are connected and fixed with a support plate 4. The straight tubes 12 and the connecting tubes 11 are shaped through the support plate 4, so as to avoid the straight tubes 12 and the connecting tubes 11 from being separated at the connection.

[0023] A plurality of heat sinks 13 are equidistantly arranged on the outer circle of the straight tube 12. The heat sink 13 is circular and can better conduct the refrigerant. The original indoor air can only contact with the straight tube 12 for heat dissipation and cooling. The use of the heat sink 13 further increases the cooling area, so that the indoor air can be cooled faster.

[0024] The support plates 4 are rotatably connected to both ends of the fan 5, and one end of the fan 5 passes through the support plate 4 and is fixedly connected to the output end of the drive motor 6. The blades of the fan 5 are arc-shaped, so that the air can better enter the heat sink 13 and the straight pipe 11. The fan 5 is driven by the drive motor 6 to quickly bring the indoor air into the straight pipe 12 and the heat sink 13.

[0025] The top of the support plate 4 is connected and fixed with the first guide plate 71 and the second guide plate 72, and the bottom of the support plate 4 is connected and fixed with the third guide plate 74. Through the support plate 4, the first guide plate 71, the second guide plate 72 and the third guide plate 74, a channel is formed so that the indoor air enters the channel under the drive of the fan 5 and contacts with the heat sink 13 and the straight tube 11 for cooling, thereby avoiding the indoor air to be well guided and achieving the effect of rapid cooling. The first guide plate 71, the second guide plate 72 and the third guide plate 74 are all provided with cavities, and water-cooling liquid is arranged in the cavity. The water-cooling liquid can isolate the straight tube 11 and the heat sink 13 in the channel, thereby avoiding the loss of cold air and ensuring that the cooling effect in the channel will not decrease. One end of the second guide plate 72 away from the first guide plate 71 is connected and fixed with one end of the arc-shaped guide plate 73. The arc-shaped guide plate 73 can guide the indoor air after the cooling is completed out of the air conditioner again, thereby performing alternating cold and hot in the room.
