[0013] Figure 2 It is a structural schematic diagram of another embodiment of the evaporator inlet pipe assembly of the utility model;
[0014] Figure 3 The utility model is a schematic diagram of the structure of the distributor in the evaporator input pipe assembly. DETAILED DESCRIPTION
[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0016] Reference Figure 1 to Figure 3 : The evaporator input pipe 1 assembly includes an input pipe 1, one end of which is provided with a pipe joint 11, which is convenient for direct connection with the condenser. The other end of the input pipe 1 is connected with a distributor 2, and the distributor 2 is provided with a distribution hole 21, which corresponds to the capillary tube 3. The distributor 2 is connected with one end of a plurality of capillary tubes 3 through the distribution hole 21, and the other end of the plurality of capillary tubes 3 is connected with a connecting pipe 5.
[0017] During installation, it can adapt to the needs of different numbers of evaporator branches, making the internal pipeline layout more flexible and maintainable. By providing a connecting pipe, it can be set accordingly according to the position of the evaporator connection port; at the same time, the entire input pipe structure is simple and easy to install with other components. In the cooling state, the refrigerant in the air conditioner flows out of the condenser, is input along the input pipe 1, and is divided into multiple capillaries 3 through the distribution hole 21 on the distributor 2. The refrigerant enters the corresponding evaporator after passing through the capillary tube 3 and the connecting pipe 5. In this way, the evaporator and the condenser can be connected through the input pipe 1 pipeline, thereby completing the refrigeration cycle inside the pipeline.
[0018] Specifically, one end of the distributor 2 is connected to the input pipe 1, and the other end is in a trumpet shape with a gradually increasing inner diameter of the pipe, and a plurality of distribution holes 21 are arranged inside the distributor 2, so that when the refrigerant passes through the distributor 2, it is connected to the capillary tube 3 along the distribution holes 21 in the trumpet shape. During installation, the corresponding distributor 2 is selected according to the actual needs of the pipeline. For example, a structure with eleven corresponding distribution holes 21 is selected. Figure 3 Eleven distribution holes 21 are arranged in an annular manner and evenly distributed along the axial direction of the distributor 2, and correspondingly, the number of capillaries 3 connected to the distribution holes 21 is the same. In this way, the specification and length of each capillary 3 can be selected according to the actual flow requirements.
[0019] The input pipe 1 includes a straight pipe portion 14, which is directly connected to the distributor 2. The refrigerant can flow directly into the distributor 2 along the straight pipe portion 14. However, a bent portion 13 can also be provided to connect the straight pipe portion 14 and one end of the bent portion 13, so that the bent portion 13 is provided between the distributor 2 and the straight pipe portion 14. The shape and angle of the bend of the bent portion can be determined according to actual needs. For example, a three-stage bend can be provided, so that the space occupied by the input pipe 1 component can be adjusted during actual installation.
[0020] The outer side of the straight pipe portion 14 is sleeved with an insulation sleeve 12. The insulation sleeve 12 can be set to a double-layer structure, that is, a double-layer structure of an insulation inner layer and a protective outer layer. In fact, an inner layer of insulation cotton material and an outer layer of rubber material can be used. The inner layer is bonded to the outer layer and then sleeved and fixed on the outer surface of the straight pipe portion 14. The inner layer can prevent heat loss during the refrigerant transmission process, and the outer layer can ensure the tightness of the inner layer, so that the entire insulation sleeve 12 is not easily damaged. In this way, the refrigeration efficiency is improved by the coordinated arrangement of the straight pipe portion 14 and the insulation sleeve 12. Furthermore, sound-absorbing cotton can also be used to wrap the outer side of the insulation layer to form a noise reduction layer, that is, the noise reduction layer is arranged between the insulation layer and the protective layer. The material of the sound-absorbing cotton can absorb and reduce the noise generated when the refrigerant passes through the pipeline.
[0021] The utility model also includes a water receiving tray 4. Specifically, the straight pipe portion 14 and the bent portion 13 are connected through the water receiving tray 4. The water receiving tray 4 can collect the condensate formed in the internal pipeline to prevent the condensate from flowing into the evaporator. At the same time, in order to adjust the direction of the pipeline joint, the connecting pipe 5 can be provided with a bent tube 51 and an arc tube 52. One end of the bent tube 51 and the arc tube 52 are both connected to the capillary tube 3, and the other end of the bent tube 51 is bent in a direction away from the capillary tube 3, and the other end of the arc tube 52 is bent toward an end close to the distributor 2. In this way, the bent tube 51 or the arc tube 52 can be selected to connect to the evaporator according to different connection positions. During the installation process, there is no need to repeatedly bend the capillary tube 3, thereby avoiding the bending and compression of the pipeline to affect the refrigerant transmission or the breakage to cause refrigerant leakage.
[0022] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
