In related technologies, the Bondi tube condensers of drinking water equipment are mainly single-layer condensers. In equipment with limited height, the height of the condenser is greatly restricted, and the heat dissipation efficiency is low, which cannot meet the heat dissipation requirements during work.

The condenser provided according to the embodiment of the first aspect of the present application, please refer to FIG. 1 to FIG. 4 , includes at least two layers of condenser tubes 100 .

It can be understood that the working principle of the condenser is that the high-temperature refrigerant flows in the condenser pipe 100, the outside air contacts the condenser pipe 100, and uses the condenser pipe 100 to perform heat exchange, dissipating the heat of the refrigerant into the air to The refrigerant cools down.

According to the condenser provided in the embodiment of the present application, the multi-layer condenser tubes 100 are arranged side by side. In the case of a limited volume of household appliances, the design of the multi-layer condenser tube 100 can increase the length of the pipeline of the condenser, thereby improving the condensation efficiency. The heat dissipation capacity of the device can solve the heat dissipation problem at high temperature.

In some embodiments of the present application, there is a small angle between two adjacent layers of condensation pipes 100 , and after the multi-layer condensation pipes 100 are arranged side by side, the volume is small, which can save space.

In some other embodiments, two adjacent layers of condensation pipes 100 are arranged in parallel, which can reduce space occupation as much as possible.

According to the condenser provided in the embodiment of the present application, two adjacent layers of condenser tubes 100 are bonded together, and there is no invalid space between the multi-layer condenser tubes 100. The thickness of the condenser in this embodiment is the same as that of a single-layer condenser The difference is not big, but the heat exchange path is longer and the condensation effect is better, which can solve the heat dissipation problem under high temperature conditions, and can take into account the heat dissipation efficiency and the space volume.

In some embodiments of the present application, the condensing pipes 100 of each layer include multiple main condensing pipe sections 102 and connecting pipe sections 104 arranged in parallel, and the connecting pipe sections 104 are arranged between two adjacent main condensing pipe sections 102, and multiple The main condensation pipe sections 102 are connected in series.

It can be understood that, as shown in FIGS. 1 to 4 , in order to increase the length of the condensing pipe 100 and increase the time for the refrigerant to flow in the condensing pipe 100 to improve heat transfer, the condensing pipe 100 is arranged in a curved shape, and the condensing pipe 100 There are multiple main condensing pipe sections 102 arranged in parallel, and the multiple main condensing pipe sections 102 are roughly arranged in a plane or in an arc-shaped curved surface, and the multiple main condensing pipe sections 102 are connected in series through a plurality of connecting pipe sections 104 .

The connecting pipe section 104 is a semicircle or other curved shape, and the two ends of the connecting pipe section 104 are respectively connected to two adjacent main condensing pipe sections 102. Along the arrangement direction of a plurality of main condensing pipe sections 102, the first connecting pipe section 104 is connected to The right end of the first main condensing pipe section 102 and the second main condensing pipe section 102, the second connecting pipe section 104 connects the left end of the second main condensing pipe section 102 and the third main condensing pipe section 102, and so on, forming a continuous bend The folded condensing pipe 100, the condensing pipe 100 has a larger total length in a smaller space, which is conducive to improving the heat exchange.

It should be noted that two adjacent main condensation pipe sections 102 are arranged in parallel or have a certain angle, which can be arranged according to needs.

In some embodiments, the connecting pipe section 104 is arc-shaped, and the bending radius of the connecting pipe section 104 is greater than or equal to 10 mm.

It can be understood that the two ends of the connecting pipe section 104 are respectively connected with the main condensation pipe section 102, and when the angle of the arc is between 90° and 180°, two adjacent main condensation pipe sections 102 can be arranged in parallel, so that the condensation pipe 100 are arranged circuitously in the working layer.

Along the direction of refrigerant transmission, the connecting pipe section 104 can transfer the refrigerant in the upstream main condensing pipe section 102 to the downstream main condensing pipe section 102, thus reducing the flow resistance in the connecting pipe section 104 and contributing to the transmission of refrigerant and the high efficiency of the condenser Heat dissipation.

When the bending radius of the connecting pipe section 104 is small, more main condenser pipe sections 102 can be arranged per unit volume, thereby improving the heat exchange efficiency of the condenser. However, limited by the process, the connecting pipe section 104 may appear as a flat pipe when bent, and as the bending radius decreases, the flat pipe ratio of the connecting pipe section 104 gradually increases. After the flat tube appears in the connecting pipe section 104 , the inner diameter decreases, which further affects the flow of the refrigerant, resulting in a decrease in the heat dissipation efficiency of the condenser. Therefore, the minimum bending radius of the connecting pipe section 104 must be limited, and the bending radius must be greater than or equal to 10 mm, which meets the limit of the manufacturing process and avoids flat pipes to ensure smooth circulation of the refrigerant in the connecting pipe section 104 .

The condenser receives the high-temperature refrigerant delivered by the compressor 0170. When the refrigerant flows in the condenser, it dissipates heat, and the temperature of the refrigerant decreases synchronously.

In some embodiments of the present application, there is a distance between the plurality of main condensing pipe sections 102 , along the refrigerant flow direction, the temperature of the refrigerant gradually decreases, and the distance between two adjacent main condensing pipe sections 102 is changing.

It can be understood that, as shown in FIG. 1 to FIG. 4 , the space between two adjacent main condensing pipe sections 102 is a row spacing, and the row spacing can allow air to circulate. Due to the change of the temperature of the refrigerant, the demand for heat dissipation is also changing, and the distance between several rows is set to have a tendency to shrink along the arrangement direction, that is, the distance between the upstream adjacent main condensing pipe sections 102 is greater than that between the downstream adjacent main condensing pipe sections 102 For details, see the first distance D1 and the second distance D2 in FIG. 2 and FIG. 3 .

During the operation of the condenser, the refrigerant is input from the end of the condenser tube 100 with a larger upward distance, that is, the temperature of the refrigerant at the end of the condenser with a larger upward distance is high, and the heat exchange speed is faster. The end of the condenser with a lower refrigerant temperature adopts a smaller row spacing, and the arrangement of the condenser tubes 100 is denser. By increasing the temperature difference between the condenser tubes 100 and the surrounding air, it is beneficial to improve the heat exchange efficiency.

In some embodiments, the distance between the upstream adjacent main condensing pipe sections 102 is 1 to 2.5 times the distance between the downstream adjacent main condensing pipe sections 102 .

In a water dispenser, the condenser is usually arranged vertically, and the refrigerant can flow from the bottom to the top of the condenser, or from the top to the bottom of the condenser.

In some embodiments, a refrigerant inlet 106 is provided at the top of each layer of condensing pipes 100 , and a refrigerant outlet 108 is provided at the bottom, and the condensing pipes 100 meander from the refrigerant inlet 106 to the refrigerant outlet 108 .

It can be understood that the condensing pipe 100 extends in a detour from the refrigerant inlet 106 to the refrigerant outlet 108 , which can increase the length of the condensing pipe 100 and increase the time for the refrigerant to flow in the condensing pipe 100 to increase heat transfer. At the same time, since the refrigerant has relatively high resistance when it moves from bottom to top in the condensation pipe 100, in the embodiment of the present application, the refrigerant inlet 106 of each layer of condensation pipe 100 is arranged at the top, and the refrigerant outlet 108 is arranged at the bottom, so that the refrigerant condenses in each layer. The flow in the tube 100 is from top to bottom.

The refrigerant is input from the top of the condensing pipe 100 and output from the bottom. The top of the condensing pipe 100 has a larger row spacing, corresponding to a higher temperature of the refrigerant, and a faster heat transfer speed. The smaller row spacing at the bottom of the condenser pipe 100 corresponds to a lower temperature of the refrigerant. By densely arranging the main condenser pipe section 102, the temperature difference between the condenser pipe 100 and the surrounding air is increased, which is beneficial to improving heat exchange efficiency.

According to an embodiment of the present application, the condenser includes a plurality of condensation pipes 100 arranged side by side, so as to increase the length and time of refrigerant circulation in the condensation pipes 100 .

In some embodiments, the condenser includes two layers of condenser pipes 100, namely a first condenser pipe 100a and a second condenser pipe 100b. A refrigerant inlet 106 is formed at the top of the first condenser pipe 100a and a second condenser pipe 100b, and a refrigerant inlet 106 is formed at the bottom of the condenser pipe. Both are formed with a refrigerant outlet 108 . The first condensing pipe 100a and the second condensing pipe 100b are arranged side by side, and the two refrigerant outlets 108 are located at the bottom.

In the related art, the refrigerant enters along the refrigerant inlet 106 of the first condensing pipe 100a, flows out along the refrigerant outlet 108 of the first condensing pipe 100a, then enters the refrigerant outlet 108 of the second condensing pipe 100b according to the shortest distance, and finally flows along the The refrigerant flows out through the refrigerant inlet 106 of the second condenser pipe 100b. In the above scheme, the refrigerant has experienced a complete flow process from bottom to top, the flow resistance of the refrigerant is relatively large, and the heat exchange efficiency is low.

In the embodiment of the present application, the refrigerant outlet 108 of the first condensing pipe 100a is connected to the refrigerant inlet 106 of the second condensing pipe 100b through the connecting pipe 110, and the refrigerant can still move from top to bottom in the second condensing pipe 100b. The resistance to flow is small, and the heat exchange efficiency of the condenser is high.

In some embodiments, the connecting pipe 110 is a straight pipe, and the straight pipe shortens the path length of the refrigerant flowing from bottom to top as much as possible, thereby improving the heat exchange efficiency of the condenser.

It can be understood that the space between two adjacent main condensing pipe sections 102 is the row spacing, and the row spacing can allow air to circulate. The condenser has a plurality of condensing pipes 100 arranged side by side. When the condensing pipes 100 are arranged, the condensing pipes 100 of each layer have an inner and outer order. The outer condensing pipe 100 can directly transfer heat to the air, and the inner condensing pipe 100 needs to transfer heat to the outer condensing pipe 100 before dissipating heat to the outside air.

In some embodiments, the main condensing pipe sections 102 of the first condensing pipe 100a and the main condensing pipe sections 102 of the second condensing pipe 100b are arranged alternately.

It can be understood that the main condensing pipe section 102 of the second condensing pipe 100b corresponds to the gap on both sides of the main condensing pipe section 102 of the first condensing pipe 100a, and the main condensing pipe section 102 of the second condensing pipe 100b can directly communicate with the outside along the gap. Heat exchange occurs in the air, which improves the heat dissipation efficiency of the condenser.

The refrigerant flows through the first condensing pipe 100a and the second condensing pipe 100b in sequence, the first condensing pipe 100a is located upstream of the refrigerant flow, and the second condensing pipe 100b is located downstream of the refrigerant flow, so the temperature inside the first condensing pipe 100a is relatively high. The temperature inside the second condensation pipe 100b is relatively low.

In some embodiments, the first condensing pipe 100a is an outer pipe, and the second condensing pipe 100b is an inner pipe, that is, when the condenser is installed in a household appliance, the first condensing pipe 100a is located on the side close to the outside air, and the second condensing pipe 100b is located on the side close to the outside air. The second condenser pipe 100b dissipates heat in the direction where the first condenser pipe 100a is located.

It can be understood that the temperature of the first condenser pipe 100a is relatively high, and the temperature of the second condenser pipe 100b is relatively low. Setting the first condenser pipe 100a as an outer pipe can improve the cooling efficiency of the condenser.

The purpose of setting the second condenser pipe 100b is to increase the pipeline length of the condenser, increase the time for the refrigerant to flow in the condenser pipe 100, and increase the heat exchange rate, so the pipeline length of the second condenser pipe 100b should be adjusted according to actual needs .

In some embodiments, the area of the layer where the second condensation pipe 100b is located is smaller than or equal to the area of the layer where the first condensation pipe 100a is located.

It can be understood that the first condensation pipe 100a is an outer pipe, which plays a main heat dissipation function, and the second condensation pipe 100b performs auxiliary heat dissipation. When the heating power is determined, the pipeline length of the condenser can be adjusted, and the second condenser tube 100b can be provided with a half layer or a full layer, and of course other ratios are also possible.

In some embodiments, metal wires 120 are provided on both sides of the condensation pipe 100 of each layer.

It can be understood that the metal wire 120 can fix and support the condensation pipe 100. When the condensation pipe 100 includes a plurality of main condensation pipe sections 102, the metal wire 120 can fix the gap between the multiple main condensation pipe sections 102. spacing, but also play a role in heat dissipation.

Metal wire 120 usually adopts steel wire, and the steel wire is attached to the surface of condenser tube 100. The steel wire is connected to condenser tube 100 by welding, sticking or winding, and the steel wire is kept in contact with condenser tube 100 to transfer heat. The steel wire can adopt various shapes, for example, the steel wire is flat and straight and fixed on both sides of the condenser pipe 100 by welding, or the steel wire is helical and attached to the surface of the condenser pipe 100 to have a larger heat dissipation area. Steel wire is divided into bright steel wire and black steel wire. Bright steel wire is manufactured by pickling process. The advantage is that the surface is clean, there is no lubricant residue, basically no smoke during welding, no desoldering, and the salt spray test is qualified; the advantage of black steel wire is that it is easy to produce in large quantities. Production, the tolerance range is easy to control, and the production cost is low.

In some embodiments, when a plurality of metal wires 120 are arranged side by side, a grid-like structure is formed.

In other embodiments, a plurality of metal wires 120 are arranged parallel to and perpendicular to each other to form a mesh structure.

Metal wires 120 are arranged on both sides of each layer of condenser tubes 100. In order to keep the two adjacent layers of condenser tubes 100 bonded together, it is necessary to reduce the two layers of metal wires 120 between adjacent two layers of condenser tubes 100 as much as possible. Pitch.

In some embodiments, the two layers of metal wires 120 between two adjacent layers of condensing tubes 100 are connected by clamping or spot welding, and no other connecting structures need to be provided, so that the distance between adjacent two layers of condensing tubes 100 is reduced as much as possible. Spacing, which helps to reduce the thickness dimension of the condenser.

Referring to FIG. 4 , when two layers of metal wires 120 are connected by spot welding, welding spots 130 are formed between the metal wires 120 .

When the two layers of metal wires 120 are connected by buckling, the buckling can be realized through the structure of the metal wires 120 as much as possible without adding additional thickness dimensions.

In some embodiments, the condenser further includes an input transition section 140 and an output transition section 150, the input transition section 140 is connected to the refrigerant inlet 106 of the first condenser pipe 100a, and the output transition section is connected to the refrigerant outlet 108 of the second condenser pipe 100b .

It can be understood that the input transition section 140 and the output transition section 150 can connect the condenser to the compressor 0170 , which is helpful for rational layout of the condenser and the compressor 0170 .

The water circuit assembly provided according to the embodiment of the second aspect of the present application includes a compressor 0170 and a condenser provided according to the embodiment of the first aspect of the present application, and the compressor 0170 is connected to the condenser.

In the case of a limited volume of household appliances, the design of the multi-layer condensing pipe 100 can increase the pipe section of the condensing pipe 100 The length can further improve the heat dissipation capacity of the condenser 100, which can solve the heat dissipation problem at high temperature. Adjacent two layers of condenser tubes 100 are bonded together, and there is no invalid space between the condenser tubes 100. The thickness of the condenser is not much different from that of a single-layer condenser, but the heat exchange path is longer and the condensation effect is better. Well, it can solve the heat dissipation problem under high temperature conditions, and can take into account both heat dissipation efficiency and space volume.
