On the top surface of the bottom plate of the housing installed at the right side of the middle guide groove, a middle diversion guide groove extending left and right is formed, which is communicated with the middle guide groove at the bottom;

[0011] The condenser and the evaporator have the same structure, and both include flat tubes coiled in an S shape. Heat exchange fins are provided between two adjacent upper and lower transverse parts of the flat tubes. One end of the flat tube is connected to the first header pipe part, and the other end of the flat tube is connected to the second header pipe part;

The first connection head is welded and fixed on the outer side wall of the first header pipe part of the condenser. A second connection head is connected to the leftmost second liquid guide cavity of the second header pipe part of the condenser. The second connection head is welded and fixed on the outer side wall of the second header pipe part of the condenser. A third connection head is connected to the rightmost first liquid guide cavity of the first header pipe part of the evaporator. The third connection head is welded and fixed on the outer side wall of the first header pipe part of the evaporator.

At the same time, it forms the two first header parts on the same first main header and the two second header parts on the same second main header, enabling the evaporator and condenser to be assembled simultaneously to form a whole, reducing the processing parts, improving the processing efficiency, reducing the processing cost, and facilitating manufacturing.

[0020] Moreover, the bottom mounting housing can collect the condensed water generated in the evaporator. At the same time, through the extended blocking part, the condensed water slowly enters the middle diversion groove and the sub-diversion groove, so that it will not be quickly evaporated by the condenser, ensuring the drying effect of the air passing through the condenser.

[0029] Embodiment, as shown inFigures 1 to 7 as shown (except Figure 4 , the heat exchange fins in the remaining drawings are omitted and not shown), a drying module of a dryer, including a bottom mounting housing 70, a condenser 10 and an evaporator 20. Two protruding strips 71 extending forward and backward are formed in the middle of the bottom surface of the bottom mounting housing 70. Vertical guide strips 72 extending vertically upward along the inner wall surface of the rear wall plate of the bottom mounting housing 70 are formed at the rear of the two protruding strips 71. An intermediate guide groove 73 is formed between the two protruding strips 71 and the vertical guide strips 72;

[0030] The condenser 10 is installed in the bottom mounting housing 70 at the right side of the intermediate guide groove 73, and the evaporator 20 is installed in the bottom mounting housing 70 at the left side of the intermediate guide groove 73. The lower parts of the condenser 10 and the evaporator 20 are close to the bottom plate of the bottom mounting housing 70;

[0031] A water storage guide groove 74 is formed on the top surface of the bottom plate of the bottom mounting housing 70 at the left side of the intermediate guide groove 73. The water storage guide groove 74 communicates with the intermediate guide groove 73 at the bottom. An intermediate diversion guide groove 75 extending left and right is formed on the top surface of the bottom plate of the bottom mounting housing 70 at the right side of the intermediate guide groove 73. The intermediate diversion guide groove 75 communicates with the intermediate guide groove 73 at the bottom;

[0032] The middle top surface of the bottom plate of the bottom mounting housing 70 extends obliquely upward and forward to form an oblique bottom plate portion 76. The front end of the oblique bottom plate portion 76 forms a horizontal bottom plate portion 77 extending horizontally forward. The bottom surfaces of the condenser 10 and the evaporator 20 are close to and cooperate with the rear part of the bottom plate of the bottom mounting housing 70 and the oblique bottom plate portion 76. It can ensure that part of the condensed water dripping from the evaporator 20 can flow backward along the oblique bottom plate portion 76 into the water storage guide groove 74.

[0033] The right end of the water storage guide groove 74 communicates with a through groove in the middle of the left side wall of the intermediate guide groove 73 at the bottom. The through groove formed in the middle of the right side wall of the intermediate guide groove 73 communicates with the intermediate diversion guide groove 75. A plurality of sub-diversion grooves 751 extending forward and backward are formed at the front and rear of the intermediate diversion guide groove 75. The sub-diversion grooves 751 communicate with the intermediate diversion guide groove 75.

[0034] A bending guide portion 731 is formed on the right side wall of the intermediate guide groove 73 at the bottom. An extending blocking portion 732 extending backward is formed at the rear end of the bending guide portion 731.

The bottom surfaces of the bending guide portion 731 and the extending blocking portion 732 are formed on the bottom surface of the intermediate guide groove 73 at the bottom.

[0035] This extended blocking portion 732 can block and reduce the speed of the condensed water in the water storage guide groove 74 flowing towards the intermediate diversion guide groove 75, thereby reducing the evaporation of the condensed water during the operation of the condenser 10 and ensuring the drying effect of the air passing through the condenser.

[0036] Furthermore, the condenser 10 and the evaporator 20 have the same structure, and both include flat tubes 11 coiled in an S shape. Heat exchange fins 12 are provided between two adjacent upper and lower transverse portions 111 of the flat tubes 11. One end of the flat tube 11 is connected to and welded to the first header portion 13, and the other end of the flat tube 11 is connected to and welded to the second header portion 14.

[0037] A plurality of connecting plates are fixed on the first header portion 13, and at least two first liquid guiding cavities 131 are separated by all the connecting plates; a plurality of connecting plates are fixed on the second header portion 14, and at least two second liquid guiding cavities 141 are separated by all the connecting plates.

[0038] In this embodiment, three connecting plates are fixed on the first header portion 13, and two first liquid guiding cavities 131 are separated by the three connecting plates. The length of the left first liquid guiding cavity 131 is basically twice or more than twice that of the right first liquid guiding cavity 131. Similarly, three connecting plates are also fixed on the second header portion 14, and two second liquid guiding cavities 141 are separated by all the connecting plates. The length of the right second liquid guiding cavity 141 is twice or more than twice that of the left second liquid guiding cavity 141.

[0039] Furthermore, at least two flattened solid bars 112 are formed in the middle of the flat tube 11, and the flat tube 11 forms at least three flow channels 113 through the flattened solid bars 112.

[0040] In this embodiment, two flattened solid bars 112 are formed in the middle of the flat tube 11, and the flat tube 11 is evenly divided into three flow channels 113. The inside of the flat tube 11 at the position of the flattened solid bars 112 is a solid body, and the flow channels 113 are formed with a plurality of partition bars to divide them into a plurality of sub-flow through holes with equal cross-sectional sizes. The number and cross-sectional sizes of the sub-flow through holes in each flow channel 113 are the same.

[0041] One end of the rightmost flow channel 113 extends into the right first liquid guiding cavity 131 and is welded and fixed. One end of the rightmost flow channel 113 communicates with the right first liquid guiding cavity 131. The other end of the rightmost flow channel 113 extends into the right second liquid guiding cavity 141 and is welded and fixed and communicates with the right second liquid guiding cavity 141.

[0042] One end of the flow passage 113 in the middle of the flat tube 11 extends into the second liquid guide cavity 141 at the right end, communicates with the second liquid guide cavity 141 at the right end and is fixedly welded. The other end extends into the first liquid guide cavity 131 on the left side, communicates with the first liquid guide cavity 131 on the left side and is fixedly welded. One end of the flow passage 113 in the left part of the flat tube 11 extends into the first liquid guide cavity 131 on the left side, communicates with the first liquid guide cavity 131 on the left side and is fixedly welded. The other end of the flow passage 113 in the left part of the flat tube 11 extends into the second liquid guide cavity 141 on the left side, communicates with it and is fixedly welded.

[0043] According to design requirements, four connecting plates can also be fixed on the first manifold part 13 to divide it into three first liquid guide cavities 131, and four connecting plates can be fixed on the second manifold part 14 to divide it into three second liquid guide cavities 141. Correspondingly, four flattened solid bars 112 need to be provided on the flat tube 11 to form five flow passages 113, and all designs can be extended in this way in turn.

[0044] Furthermore, a first connector 1 is connected to the first liquid guide cavity 131 at the right end of the first manifold part 13 of the condenser 10. The first connector 1 is fixedly welded to the outer side wall of the first manifold part 13 of the condenser 10. A second connector 2 is connected to the second liquid guide cavity 141 at the left end of the second manifold part 14 of the condenser 10. The second connector 2 is fixedly welded to the outer side wall of the second manifold part 14 of the condenser 10. A third connector 3 is connected to the first liquid guide cavity 131 at the right end of the first manifold part 13 of the evaporator 20. The third connector 3 is fixedly welded to the outer side wall of the first manifold part 13 of the evaporator 20. A fourth connector 4 is connected to the second liquid guide cavity 141 at the left end of the second manifold part 14 of the evaporator 20. The fourth connector 4 is fixedly welded to the outer side wall of the second manifold part 14 of the evaporator 20.

[0045] Furthermore, a total feed pipe 40 is connected to the first connector 1. The second connector 2 is connected to one end of the throttling device through a connecting pipe. The other end of the throttling device is connected to the third connector 3 through a connecting pipe. A discharge pipe 700 is connected to the fourth connector 4.

[0046] The throttling device is composed of a dryer 50 and a capillary tube 60. The second connector 2 is connected to one end of the dryer 50 through a connecting pipe. The other end of the dryer 50 is connected to one end of the capillary tube 60. The other end of the capillary tube 60 is connected to the third connector 3 through a connecting pipe.

[0047] Both the dryer 50 and the capillary tube 60 are common components in refrigeration equipment and can adopt existing known structures, which will not be elaborated here.

[0048] When this embodiment is in use, the refrigerant coolant enters the first liquid guide cavity 131 at the right end of the first manifold part 13 of the condenser 10 from the total feed pipe 40, then passes through the flow channel 113 on the right side of the corresponding flat tube 11, and then enters the second liquid guide cavity 141 at the right end of the second manifold part 14 of the condenser 10, and then enters the flow channel 113 in the middle of the corresponding flat tube 11, and then enters the first liquid guide cavity 131 at the left end of the first manifold part 13 of the condenser 10, and then enters the flow channel 113 on the left part of the corresponding flat tube 11, and then enters the second liquid guide cavity 141 at the left end of the second liquid guide cavity 141 of the condenser 10, and then enters the dryer 50 for drying, and then enters the capillary 60. Then, it enters the first liquid guide cavity 131 at the right end of the first manifold part 13 of the evaporator 20. Then, like the flow in the condenser 10, it finally flows out from the second liquid guide cavity 141 at the left end of the second manifold part 14 of the evaporator 20 and flows out from the discharge pipe 700 to the subsequent components. In this embodiment, it flows to the compressor, which is a conventional structure and will not be elaborated here.

[0049] In this embodiment, in the condenser 10 and the evaporator 20, only a single flat tube 11, a first manifold part 13, a second manifold part 14 and a plurality of heat exchange fins 12 are required. Their assembly and welding are convenient, greatly improving the processing efficiency and having good use effects.

[0050] As Figure 5 shown, the first manifold parts 13 of the condenser 10 and the evaporator 20 are formed on the same first total manifold 100, and the second manifold parts 14 of the condenser 10 and the evaporator 20 are formed on the same second total manifold part 200.

[0051] The first manifold parts 13 of the condenser 10 and the evaporator 20 can be arranged on the same first total manifold 100, and the two second manifold parts 14 can be formed on the same second total manifold part 200. With such an arrangement, only one first total manifold 100, one second total manifold part 200 and two flat tubes 11 are required for the condenser 10 and the evaporator 20 of this embodiment. The number of processed parts is further reduced, making the assembly more convenient, the processing simpler and the processing efficiency higher.

[0052] As Figure 8 shown, the throttling device can also directly adopt a throttle valve 80. However, the structural settings of the condenser 10 and the evaporator 20 using the throttle valve 80 are exactly opposite;

[0053] The structure of the condenser 10 is such that one end of the rightmost flow passage 113 extends into the first liquid guide cavity 131 at the right end and is welded and fixed. One end of the rightmost flow passage 113 communicates with the first liquid guide cavity 131 at the right end, and the other end of the rightmost flow passage 113 extends into the second liquid guide cavity 141 at the right end and is welded and fixed and communicates with the second liquid guide cavity 141 at the right end;

[0054] One end of the flow passage 113 in the middle of the flat tube 11 extends into the second liquid guide cavity 141 at the left end and communicates with and is welded and fixed to the second liquid guide cavity 141 at the left end, and the other end extends into the first liquid guide cavity 131 at the right end and communicates with and is welded and fixed to the first liquid guide cavity 131 at the right end. One end of the flow passage 113 in the left part of the flat tube 11 extends into the first liquid guide cavity 131 on the left side and communicates with and is welded and fixed to the first liquid guide cavity 131 on the left side, and the other end of the flow passage 113 in the left part of the flat tube 11 extends into the second liquid guide cavity 141 on the left side and communicates with and is welded to it.

[0055] Meanwhile, a third connector 3 is connected to the upper part of the first liquid guide cavity 131 at the left end of the first manifold portion 13 of the evaporator 20. The third connector 3 is welded and fixed to the outer side wall of the first manifold portion 13 of the evaporator 20. A fourth connector 4 is connected to the upper part of the second liquid guide cavity 141 at the right end of the second manifold portion 14 of the evaporator 20. The fourth connector 4 is welded and fixed to the outer side wall of the second manifold portion 14 of the evaporator 20.

[0056] Meanwhile, a total feed pipe 40 is connected to the first connector 1. The second connector 2 is connected to one end of a throttle valve 80 through a connecting pipe. The other end of the throttle valve 80 is connected to the fourth connector 4 through a connecting pipe. A discharge pipe 700 is connected to the third connector 3.

[0057] This structure directly replaces the dryer 50 and the capillary tube 60 with a throttle valve. Its effect is basically the same as that of using the dryer 50 and the capillary tube 60, but its structure is simpler and manufacturing is more convenient. The throttle valve can be any of the various throttle valves used in existing known refrigeration systems, which will not be elaborated here.

[0058] The remaining structure is the same as that of the heat exchange component using the dryer 50 and the capillary tube 60 as the throttling device, which will not be elaborated here.

[0059] Finally, the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Those of ordinary skill in the relevant technical field can also make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention shall be defined by the claims.
