Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, and specifically, to a heat exchanger supporting non-stop defrosting, an air conditioning outdoor unit provided with the heat exchanger supporting non-stop defrosting, an air conditioner including the air conditioning outdoor unit, and an air conditioning system provided with the heat exchanger not supporting non-stop defrosting. Background Art

[0002] When a traditional air conditioner is heating, the outdoor heat exchanger in the outdoor unit of the air conditioner is very easy to frost, so it needs to be defrosted frequently. The commonly used method is: first control the air conditioner to stop, then control the four-way valve to change direction, and then control the air conditioner to start and switch to the cooling mode to melt the frost on the outdoor heat exchanger through the high-temperature refrigerant; when the defrosting process is completed, the air conditioner is controlled to stop again, and the four-way valve is controlled to change direction again, and then the air conditioner is controlled to start and switch to the heating mode. However, the disadvantage of this defrosting method is that the indoor side does not provide heat during defrosting, and it also absorbs part of the indoor heat, resulting in large fluctuations in indoor temperature, which makes users feel uncomfortable.

[0003] In order to solve the shortcomings of the above defrosting methods, such as Figure 1 and Figure 2 As shown, the existing solution is: an electric heating block 92 is set at one end of the outdoor heat exchanger 91 (i.e., the elbow 911 of the heat exchange tube); wherein the electric heating block 92 is provided with a avoidance groove to accommodate the elbow 911 of the heat exchange tube. When the outdoor heat exchanger 91 needs to be defrosted, the electric heating block 92 is turned on to heat the refrigerant flowing through the heat exchange tube through the elbow 911 of the heat exchange tube, thereby increasing the temperature of the refrigerant and achieving the purpose of defrosting. However, the above solution has the following shortcomings:

[0004] First, due to the limited heat exchange area between the electric heating block 92 and the heat exchange tube, and the fact that the refrigerant has a certain flow rate in the heat exchange tube, the degree of heating of the refrigerant by the electric heating block 92 is limited, and the heating effect is not increased, which leads to poor heat absorption effect of the refrigerant;

[0005] Second, the defrosting of the outdoor heat exchanger 91 is achieved by increasing the temperature of the refrigerant flowing through the fins. Although the temperature of the refrigerant is increased by the electric heating block 92, the overall temperature is still basically maintained at a low temperature, resulting in a poor defrosting effect. The fins are still at a greater risk of frosting, especially when the ambient temperature of the outdoor heat exchanger 91 is low. The defrosting effect that can be achieved by the above solution is extremely limited, resulting in a high probability of frosting on the outdoor heat exchanger 91. Summary of the invention

[0039] Implementation example of heat exchanger supporting non-stop defrosting

[0040] Reference Figure 3 The heat exchanger 100 supporting non-stop defrosting includes a body 1, a heating pipe 2 and a connecting component 3. Figure 4 and Figure 5 The main body 1 includes a plurality of fins 11 and a first heat exchange tube 12. The plurality of fins 11 are arranged in parallel. The first heat exchange tube 12 is arranged on the main body 1 in a winding manner, and the first heat exchange tube 12 passes through the fins 11, so that the refrigerant flowing through the first heat exchange tube 12 can fully exchange heat with each fin 11. Preferably, the fins 11 and the first heat exchange tube 12 are both made of copper; as another optional solution, the fins 11 and / or the first heat exchange tube 12 can also be made of copper alloy tubes; as another optional solution, the fins 11 and / or the first heat exchange tube 12 can also be made of aluminum alloy. The fins 11 and the first heat exchange tube 12 made of copper, copper alloy or aluminum alloy have good thermal conductivity to ensure the cooling and heating effects of the air conditioner equipped with the heat exchanger 100 supporting non-stop defrosting.

[0041] In addition, at least some of the fins 11 are provided with notches, which penetrate the fins 11 in the length direction L of the body 1, and a plurality of notches form a receiving groove 111. Furthermore, the body 1 is also provided with a first connecting portion 13, which can be fixedly connected to the fins 11 and / or the first heat exchange tube 12; wherein the first connecting portion 13 is provided with a connecting hole 131.

[0042] Combination Figure 6, the heating tube 2 is installed in the receiving groove 111, and the heating tube 2 is adjacent to the body 1. By setting the heating tube 2 and setting a notch on the fin 11 so that the notches on the multiple fins 11 form the receiving groove 111 for receiving the heating tube 2, the contact area between the heating tube 2 and the body 1 is greatly increased, so that when the body 1 is defrosted, the heat generated by the heating tube 2 can be directly and quickly transferred to the fin 11, thereby quickly melting the frost on the fin 11; at the same time, the heat generated by the heating tube 2 can also be transferred to the refrigerant in the first heat exchange tube 12 through the fin 11. Since the first heat exchange tube 12 is in full contact with the multiple fins 11, the heat generated by the heating tube 2 can also be fully absorbed and converted by the refrigerant, so that the heat is transferred to the indoor side for heating, thereby improving the heating effect of the indoor side.

[0043] Preferably, each fin 11 is provided with a plurality of notches, and in the present embodiment, the heating tube 2 is installed in the receiving groove 111 in a serpentine shape, so that the contact area between the heating tube 2 and the body 1 is maximized as much as possible, thereby further improving the heat exchange efficiency between the heating tube 2 and the fin 11, and improving the defrosting effect of the body 1 and the heating effect of the air conditioner or air conditioning system provided with the heat exchanger 100 supporting non-stop defrosting.

Compared with embedding the heating tube 2 in the fin 11 like the first heat exchange tube 12, this design makes the production and assembly of the heat exchanger 100 supporting non-stop defrosting more convenient, and also makes the maintenance and replacement of the heating tube 2 more convenient.

[0045] The heating tube 2 preferably includes a heat transfer sleeve 21 and an electric heating wire 12. The heat transfer sleeve 21 is installed in the accommodating groove 111, and the electric heating wire 12 is inserted into the heat transfer sleeve 21. This design can improve the safety of the heat exchanger 100 supporting non-stop defrosting while ensuring the defrosting effect on the body 1. The heat transfer sleeve 21 is preferably made of copper to ensure the defrosting effect on the body 1, and can also ensure the heating effect of the air conditioner or air conditioning system provided with the heat exchanger 100 supporting non-stop defrosting; as another optional solution, the heat transfer sleeve 21 can also be made of copper alloy; as another optional solution, the heat transfer sleeve 21 can also be made of aluminum alloy.

[0046] Combination Figure 7The connection assembly 3 includes a clip 31 and a locking bolt 32. The clip 31 is provided with a through hole, and the through hole passes through the clip 31. When the body 1, the heating tube 2 and the connection assembly 3 are assembled, the locking bolt 32 is passed through the through hole and then threadedly connected with the connection hole 131, so that the clip 31 presses and fixes the heating tube 2 on the body 1. Through the structural design of the connection assembly 3, the connection assembly 3 and the first connection part 13 on the body 1 can be quickly disassembled and assembled, and has the advantage of convenient disassembly and assembly.

[0047] As a preferred solution, the clip 31 may have an arc portion and a second connection portion, wherein the arc portion is adjacent to the heating tube 2, and the through hole is formed on the second connection portion. This design allows the clip 31 to better avoid excessive deformation of the heating tube 2 and / or the clip 31 when the body 1 is used to clamp and fix the heating tube 2, and also ensures the reliability and stability of the clamping and fixing of the heating tube 2. Preferably, a clip 31 has two second connection portions, and the arc portion is connected between the two second connection portions to further enhance the firmness of the clamping and fixing of the heating tube 2. Correspondingly, two connection holes 131 may be provided on the first connection portion 13 to correspond to the two through holes of the clip 31, and a fixing assembly may also be provided to cooperate and connect with the clip 31; wherein the fixing assembly includes two first connection portions 13, and the two first connection portions 13 correspond to the two second connection portions one by one, so that the connection hole 131 on one first connection portion 13 matches the through hole on the corresponding second connection portion.

[0048] In addition, the number of connecting components 3 and fixing components (or the first connecting part 13 with two connecting holes 131) is preferably four groups, the four groups of connecting components 3 correspond one-to-one to the four groups of fixing components, and the four groups of fixing components are roughly distributed at the four corners of the main body 1.

[0049] Furthermore, the heat exchanger 100 supporting non-stop defrosting further includes a temperature sensor, which is mounted on the body 1; wherein the temperature sensor can be arranged on the fins 11, between the fins 11, or on the first heat exchange tube 12. The temperature sensor is used to detect the temperature of the body 1 in real time, so as to facilitate the defrosting of the body 1 in time, and is also conducive to reducing energy consumption.

[0050] In summary, it can be seen that the heat exchanger 100 supporting non-stop defrosting provided by the present invention can improve the defrosting effect and the auxiliary heating effect in the heating mode.
