The inner wall of each connecting port is provided with a fixing ring 151, and an installation groove is formed between the fixing ring 151 and the inner wall of the connecting port. And a sealing element is arranged in each connecting port and comprises a first sealing part 141, a second sealing part 142 and a connecting part 143, the first sealing part 141 is embedded in the mounting groove, and one side of the first sealing part 141 facing the fixing ring 151 is in sealing fit with the fixing ring 151. The second sealing portion 142 is sleeved on the connection pipe 130, the second sealing portion 142 is located between the fixing ring 151 and the connection pipe 130, the second sealing portion 142 is connected to the first sealing portion 141 through the connection portion 143, and the first sealing portion 141, the second sealing portion 142 and the connection portion 143 are integrally formed. The second sealing portion 142 is in sealing fit with the connecting pipe 130, a gap 152 is formed between the second sealing portion 142 and the first sealing portion 141, and a guide inclined surface 144 is provided at a connection position of the second sealing portion 142 and the connecting portion 143. Connecting pipe 130 cover is equipped with clamping ring 131, clamping ring 131 and connecting pipe 130 integrated into one piece, and clamping ring 131 deviates from the sealed cooperation in one side of solid fixed ring 151 with connecting portion 143.

In one embodiment of the present invention, the second sealing portion 142 has a size suitable for being assembled with the connection pipe 130 in the axial direction of 10mm to 15mm, and the compression amount of the second sealing portion 142 in the radial direction is 20% to 25%.

Here, the compression amount of the second sealing portion 142 in the radial direction refers to the compression amount of the interference fit between the second sealing portion 142 and the connection pipe 130. The fitting size of the second sealing portion 142 in the axial direction is 10mm to 15mm, and in the case where the compression amount in the radial direction is 20% to 25%, the force required to pull out the connection pipe 130 needs to be 50N to 70N, which can satisfy the requirements that the connection pipe 130 itself is difficult to be pulled out and that it is manually detachable. If the assembling size and compression rate of the second sealing part 142 are designed to be small, the connection pipe 130 may be separated; on the contrary, if the second sealing portion 142 is designed to have a large assembling size and a large compression rate, it is difficult to manually pull out the connection pipe 130, and the sealing member is also broken.

In the embodiment of the present invention, as shown in fig. 1a and 22a, in the case that the water dispenser is not provided with the second container 300, the water dispenser outputs only cold water and warm water, at this time, the connector body 100 only needs to be provided with the first cold water inlet 110, the second cold water inlet 115, the first tap water intake 112 and the second tap water intake 116, wherein the first cold water inlet 110 is communicated with the first tap water intake 112, the second cold water inlet 115 is communicated with the second tap water intake 116, the first cold water inlet 110 and the second cold water inlet 115 are respectively communicated with two cold water outlet pipes of the first container 400, the first tap water intake 112 is communicated with the warm water tap, and the second tap water intake 116 is communicated with the cold water tap.

Of course, the other connection ports of the connector body 100 except for the first cold water inlet 110, the second cold water inlet 115, the first faucet water intake 112 and the second faucet water intake 116 may be plugged by plugs, and the connector body may also be used in a water dispenser without the second container 300.

In the embodiment of the present invention, the connector body 100 is further formed with an exhaust pipe 120, the exhaust pipe 120 is communicated with the second hot water connection port 118, the exhaust pipe 120 is located at the first side of the connector body 100, and the exhaust pipe 120 is used to exhaust gas at the upper portion of the second container 300. By communicating the exhaust pipe 120 with the second hot water connection port 118, it is no longer necessary to separately provide the exhaust pipe 120 on the second container 300, and the gas in the second container 300 can enter the exhaust pipe 120 through the second hot water connection port 118 and be exhausted through the exhaust pipe 120, so that the pressure in the second container 300 is prevented from being excessively high.

It should be noted that the height of the exhaust pipe 120 needs to be higher than the height of the hot water tap to ensure that gas can be discharged through the exhaust pipe 120 and water cannot be discharged through the exhaust pipe 120. Of course, a waterproof and gas permeable membrane may be provided in the exhaust pipe 120, and gas may be discharged while water is not discharged.

In the embodiment of the present invention, the first cold water inlet 110, the second cold water inlet 115, the first tap water intake 112, the second tap water intake 116, and the third tap water intake 119 are located at a first side of the connector body 100, and the first hot water connection port 111 and the second hot water connection port 118 are located at a second side of the connector body 100. Since the first container 400 is located at one side of the connector body 100 and the second container 300 is located at the other side of the connector body 100 when being installed, the connection of the connector body 100 with the first container 400 and the second container 300 can be facilitated by providing the cold water inlet and the hot water connection port at different sides of the connector body 100.

In an embodiment of the present invention, as shown in fig. 16, in order to further avoid heat exchange between cold water and hot water, the first diversion section 210 and the second diversion section 211 are not directly communicated, the waterway connection further includes a one-way valve 220, the one-way valve 220 is disposed between the first diversion section 210 and the second diversion section 211, and the one-way valve 220 is used for allowing water in the first diversion section 210 to flow into the second diversion section 211, so that water in the second diversion section 211 cannot flow into the first diversion section 210.

By arranging the check valve 220 between the first cold water inlet 110 and the first hot water connection port 111, temperature cross-over between hot water in the second container body 310 and cold water in the first container body 420 can be prevented, energy consumption of the water dispenser is reduced, and user experience is improved.

In the embodiment of the present invention, the check valve 220 is formed with a water inlet end and a water outlet end, the second end of the first flow passage 113 and the first tap water intake 112 are respectively communicated with the first end of the first guide section 210, the second end of the first guide section 210 is communicated with the water inlet end, the first end of the second flow passage 114 is communicated with the first end of the second guide section 211, the second end of the second flow passage 114 is communicated with the first hot water connection port 111, and the second end of the second guide section 211 is communicated with the water outlet end.

In the embodiment of the present invention, as shown in fig. 17 and 18, the check valve 220 includes a valve body 221 and a valve core 223, a valve body flow passage is formed inside the valve body 221, a water inlet end and a water outlet end are respectively formed at two ends of the valve body flow passage, that is, a water inlet end is formed at the lower end of the valve body flow passage, and a water outlet end is formed at the upper end of the valve body flow passage. The inner wall of the valve body flow passage is formed with a first sealing surface 222, and the first sealing surface 222 is horizontally arranged and positioned below the valve core 223. The valve core 223 is arranged in the valve body flow passage, the valve core 223 is made of silica gel, a second sealing surface 224 is formed at the bottom of the valve core 223, and the valve core 223 is suitable for being switched between a closed position and an open position; in the closed position, the first sealing surface 222 engages the second sealing surface 224 and blocks the valve flow path, and in the open position, the second sealing surface 224 is spaced from the first sealing surface 222 and the valve flow path is open.

As shown in fig. 20, the first container 400 is located above the connector body 100, the second container 300 is located below the connector body 100, water enters the valve body flow passage through the first container 400 and the first cold water inlet 110 in sequence under the action of gravity, at this time, the pressure of cold water is greater than that of hot water, the water flows upwards in the valve body flow passage, the water pushes the valve core 223 to move from the closed position to the open position against the self-gravity, and because no sealing surface hermetically matched with the valve core 223 is arranged above the valve core 223, the cold water continuously flows into the first hot water connecting port through the valve body flow passage and finally enters the second container 300.

As shown in fig. 19, when the hot water is heated, expanded and returned, the pressure of the cold water is lower than that of the hot water, the water flows downward in the valve body flow passage, the water presses the valve element 223 downward, so that the second sealing surface 224 at the bottom of the valve element 223 is attached to the first sealing surface 222, and the valve element 223 blocks the valve body flow passage. And the greater the pressure of water applied to the valve element 223, the closer the second sealing surface 224 is attached to the first sealing surface 222, and the better the sealing performance. Because the valve core 223 blocks the valve body flow passage, hot water can not enter the first container 400 through the valve body flow passage, thereby preventing temperature cross between cold water and hot water, reducing energy consumption and improving user experience.

Here, the material of the valve body 221 is not limited to silicone, and may be rubber or other flexible material.

In the embodiment of the present invention, the valve core 223 is a cylinder, the cross section of the valve body flow passage is circular, and a certain gap is formed between the valve core 223 and the inner wall of the valve body flow passage to ensure that the valve core 223 can move freely in the valve body flow passage.

In an embodiment of the present invention, the first sealing surface 222 is an annular flat surface, the first sealing surface 222 is horizontally disposed, the second sealing surface 224 is a circular flat surface, the second sealing surface 224 is horizontally disposed, and the outer diameter of the first sealing surface 222 is greater than the diameter of the second sealing surface 224. By making the outer diameter of the first sealing surface 222 larger than the diameter of the second sealing surface 224, even if the position of the valve element 223 is displaced by a certain amount in the closed position, no leakage occurs between the first sealing surface 222 and the second sealing surface 224, so that the machining accuracy requirements of the valve element 223 and the valve body 221 are reduced, and the production cost is reduced.

In one embodiment of the present invention, as shown in fig. 21, the second sealing surface 224 is a conical surface, and the first sealing surface 222 is an inclined annular surface, and by setting the second sealing surface 224 to be a conical surface, the closer the second sealing surface 224 is attached to the first sealing surface 222, the better the sealing performance when the spool 223 is subjected to downward pressure.

In the embodiment of the present invention, a recess 225 is disposed on a side of the valve spool 223 away from the first sealing surface 222, and the recess 225 may make the valve spool 223 hollow, reduce the weight of the valve spool 223, and increase the buoyancy of the valve spool 223. The upward moving water only needs to exert a small pushing force on the valve spool 223 to push the valve spool 223 away from the closed position.

In the embodiment of the present invention, a plurality of limiting portions 226 are disposed at intervals on the inner wall of the valve body flow passage, and the limiting portions 226 are located on a side of the valve core 223 away from the first sealing surface 222, that is, the limiting portions 226 are located above the valve core 223. In the open position, the side of the valve element 223 facing away from the first sealing surface 222 abuts the stop 226. Because a gap is formed between two adjacent limiting parts 226, water can flow through the gap, and the valve core 223 cannot block the valve body flow passage.

It should be noted that the number of the limiting portions 226 may be two, or three or more, and the distance between two adjacent limiting portions 226 may be equal or unequal.

In an embodiment of the present invention, the second container 300 includes a second container body having a second receiving cavity formed therein, and a hot water inlet pipe having a first end communicating with the second receiving cavity and a second end communicating with the first hot water connection port.

In an embodiment of the present invention, as shown in fig. 23, 24 and 25, the second container further includes an insulation casing assembly 340, the second container body 310 is internally formed with a second receiving cavity, the insulation casing assembly 340 is wrapped outside the second container body 310, and the insulation casing assembly 340 is made of a hard insulation material.

Because heat preservation casing subassembly 340 is made by the stereoplasm material, heat preservation casing subassembly 340 has fixed shape, makes things convenient for the installation of second container, and the installation can not produce harm to human body and environment for automated production can be realized in the installation of second container, improves production efficiency.

It should be noted that, the hard material here means that the heat preservation shell has a fixed shape after the heat preservation shell is made of the material.

In one embodiment of the present invention, the material of the thermal insulation casing component 340 is CBS glass fiber foam or melamine molding material.

In the embodiment of the present invention, as shown in fig. 23 and 24, both the second container body 310 and the thermal insulation casing assembly 340 are rectangular, and since the second container installation area is generally a rectangular area, if the second container body 310 and the thermal insulation casing assembly 340 are configured as a cylinder or a sphere, a lot of space in the second container installation area cannot be effectively utilized, and the space utilization rate is low. By arranging the second container body 310 and the heat-insulating housing assembly 340 as cuboids, the space in the second container installation area is effectively utilized, and the capacity of the second container body 310 is also increased.

In an embodiment of the present invention, as shown in fig. 23, the thermal insulation casing assembly 340 includes a first casing 341 and a second casing 342, the first casing 341 is located at one side of the second container body 310, the second casing 342 is located at the other side of the second container body 310, and the second casing 342 is connected to the first casing 341 by a snap or a screw, so as to facilitate the installation and the removal of the thermal insulation casing assembly 340.

Here, the connection method of the first casing 341 and the second casing 342 is not limited to this, and the first casing and the second casing may be connected by gluing or heat fusion. The heat-insulating housing assembly 340 is not limited to the combination of the first housing 341 and the second housing 342, and may be configured by a plurality of housings, and the number of housings is specifically determined by the shape and size of the heat-insulating housing assembly 340.

The first end of the water outlet pipe 320 is communicated with the top of the second accommodating cavity, and the gas in the second accommodating cavity can be discharged through the water outlet pipe 320, so that the exhaust pipe 120 is not required to be separately arranged, the structure of the second container is simplified, and the production cost is reduced.

In the embodiment of the present invention, as shown in fig. 23 and 26, the water inlet pipe 330 is installed at the upper portion of the second container body 310, a first end of the water inlet pipe 330 communicates with the second receiving chamber, and the first end of the water inlet pipe 330 extends downward to the bottom of the second receiving chamber. The first end of the water inlet pipe 330 extends downwards to the bottom of the second accommodating cavity, so that cold water entering through the water inlet pipe 330 can be located at the bottom of the second container body 310, the heating pipe 360 can directly heat the cold water, the heating efficiency of the heating pipe 360 is improved, and the energy consumption of the heating pipe 360 is reduced. Meanwhile, since the cold water is located at the bottom of the second accommodating cavity after entering the second accommodating cavity, the hot water at the upper part of the second accommodating cavity is not affected, and the hot water output through the water outlet pipe 320 is prevented from being affected by the cold water. The water inlet pipe 330 is also a hard pipe body so that the second end of the water inlet pipe 330 can be conveniently plugged with the first hot water connector. In the related art, the water inlet pipe 330 is arranged at the bottom of the side wall of the second container body 310, and the second end of the water inlet pipe 330 is inconvenient to connect with the first hot water connector, so that automatic production is difficult to realize.

In the embodiment of the present invention, as shown in fig. 23, the thermal insulation casing assembly 340 is provided with at least two through holes, sealing rings are disposed in the through holes, annular clamping grooves are disposed on the outer peripheral surfaces of the sealing rings, the edges of the through holes are clamped in the corresponding clamping grooves, and the second end of the water outlet pipe 320 and the second end of the water inlet pipe 330 respectively penetrate through the corresponding sealing rings. By arranging the sealing ring, the heat is prevented from being lost outwards through annular gaps among the through holes, the water outlet pipe 320 and the water inlet pipe 330, and the heat insulation performance of the heat insulation shell assembly 340 is improved.

In the embodiment of the present invention, as shown in fig. 25, a mounting hole is formed in a side wall of the second accommodating chamber, a sealing ring is disposed in the mounting hole, the second temperature sensor 350 is inserted into the mounting hole and penetrates through the sealing ring, and a distance between the second temperature sensor 350 and the first end of the water inlet pipe 330 is less than 30 mm. Because the second temperature sensor of the second container in the related art is coated with the heat-conducting silicone grease, and the second temperature sensor is inserted into the heat-conducting pipe, the installation mode can cause the detected temperature value to be inconsistent with the actual temperature value, the second container of the utility model directly inserts the second temperature sensor 350 into the second containing cavity to be contacted with water, and the installation position is near the water outlet of the water inlet pipe 330, so that the real data of the water temperature during water inlet can be fed back to the electric control board, and the electric control board can accurately control the temperature.

In the embodiment of the present invention, as shown in fig. 24, the second container further includes a heating tube 360, the heating tube 360 is installed at the bottom of the second accommodating chamber, and the heating tube 360 is a spiral heating tube, so that the spiral heating tube can increase the contact surface with water, improve the heating efficiency of the heating tube 360, and reduce the space occupied by the heating tube 360. In order to accurately control the temperature of the water in the second accommodating chamber, a temperature controller and a temperature limiter are disposed on the sidewall of the second container body 310, and the heating tube 360 is electrically connected to the temperature controller and the temperature limiter, respectively.

In an embodiment of the present invention, the heating tube 360 may also be disposed outside the second container body 310, i.e., between the second container body 310 and the thermal insulation case assembly 340.

In the embodiment of the present invention, as shown in fig. 27, the water dispenser further includes:

a refrigeration assembly including a condenser 510, an evaporator 520, and a compressor 530, an outlet of the compressor 530 being in communication with an inlet of the condenser 510, an outlet of the condenser 510 being in communication with an inlet of the evaporator 520, and an outlet of the evaporator 520 being in communication with an inlet of the compressor 530.

In an embodiment of the present invention, as shown in fig. 27 to 30, the condenser 510 includes a plurality of layers of condensation tubes, each layer of condensation tube includes a plurality of parallel main condensation sections and a connection section connecting adjacent main condensation sections, and a distance between adjacent upstream main condensation sections is greater than a distance between adjacent downstream main condensation sections along a refrigerant flowing direction.

It can be understood that the condenser 510 works on the principle that a high-temperature refrigerant flows in the condensation pipe 511 of the condenser 510, external air contacts the condensation pipe 511, and heat exchange is performed by the condensation pipe 511 to dissipate heat of the refrigerant into the air, so as to cool the refrigerant.

Through setting up side by side between the multilayer condenser pipe 511, under the limited condition of domestic appliance volume, adopt the design of multilayer condenser pipe 511, can increase the pipeline length of condenser 510, and then promote condenser 510's heat-sinking capability, can solve the heat dissipation problem under the high temperature.

In the embodiment of the present invention, as shown in fig. 27 to fig. 30, two adjacent layers of the condensation pipes 511 have a smaller included angle, and after the multiple layers of the condensation pipes 511 are arranged side by side, the volume is smaller, so that the space can be saved.

In an embodiment of the present invention, the two adjacent layers of the condensation pipes 511 are arranged in parallel, so that the occupied space can be reduced as much as possible.

Through laminating between with adjacent two-layer condenser pipe 511 and connecting, there is not invalid space between the multilayer condenser pipe 511, and the thickness of this embodiment condenser 510 is not big with the thickness difference of individual layer condenser 510, but the heat transfer route is longer, and the condensation effect is better, can solve the heat dissipation problem under the high temperature condition, can compromise radiating efficiency and space volume.

In the embodiment of the present invention, each layer of the condensation pipes 511 includes a plurality of main condensation pipe sections 513 and a connection pipe section 514 arranged in parallel, the connection pipe section 514 is arranged between two adjacent main condensation pipe sections 513, and a plurality of main condensation pipe sections 513 may be connected in series.

It can be understood that, as shown in fig. 27 to 30, in order to increase the length of the condensation duct 511 and increase the time for the refrigerant to flow in the condensation duct 511 to improve the heat exchange amount, the condensation duct 511 is arranged in a curved shape, the condensation duct 511 has a plurality of main condensation duct sections 513 arranged in parallel, the plurality of main condensation duct sections 513 are arranged substantially in a plane or an arc-shaped curved surface, and the plurality of main condensation duct sections 513 are connected in series by a plurality of connecting duct sections 514.

The connecting pipe section 514 is in a semicircular shape or other curved shapes, two ends of the connecting pipe section 514 are respectively connected with two adjacent main condensation pipe sections 513, along the arrangement direction of the main condensation pipe sections 513, the first connecting pipe section 514 is connected with the right ends of the first main condensation pipe section 513 and the second main condensation pipe section 513, the second connecting pipe section 514 is connected with the left ends of the second main condensation pipe section 513 and the third main condensation pipe section 513, and so on, the continuously bent condensation pipe 511 is formed, and the total length of the condensation pipe 511 is larger in a smaller space, so that the heat exchange amount is favorably improved.

It should be noted that two adjacent main condensation sections 513 are disposed in parallel or have a certain included angle therebetween, and may be disposed as required.

The condenser 510 receives a high-temperature refrigerant sent from the compressor 530, and when the refrigerant flows in the condenser 510, heat is radiated to the outside, and the temperature of the refrigerant is lowered simultaneously.

In the embodiment of the present invention, the plurality of main condensation pipe sections 513 have a spacing therebetween, and the temperature of the refrigerant gradually decreases along the refrigerant flowing direction, and the spacing between two adjacent main condensation pipe sections 513 changes.

It will be appreciated that the space between adjacent main condenser sections 513 is a line spacing, as shown in fig. 27-30, that allows air to flow through. As the temperature of the refrigerant changes, the heat dissipation requirement also changes, and the line pitches are set to have a decreasing trend along the arrangement direction, that is, the pitch between adjacent upstream main condensation pipe sections 513 is greater than the pitch between adjacent downstream main condensation pipe sections 513, specifically, the first pitch H1 and the second pitch H2 in fig. 28 and 29.

During the operation of the condenser 510, the refrigerant is input from the end of the condenser tube 511 with the larger ascending distance, that is, the temperature of the refrigerant at the end of the condenser tube 510 with the larger ascending distance is high, and the heat exchange speed is high. The lower one end of refrigerant temperature adopts less line spacing on condenser 510, and the arrangement of condenser pipe 511 is more intensive, through the difference in temperature that improves condenser pipe 511 and ambient air, is favorable to promoting heat exchange efficiency.

In one embodiment of the present invention, the spacing between adjacent upstream main condensation duct sections 513 is between 1 and 2.5 times the spacing between adjacent downstream main condensation duct sections 513.

In a water dispenser, the condenser 510 is generally vertically disposed, and the refrigerant may flow from the bottom of the condenser 510 to the top, or from the top of the condenser 510 to the bottom.

In an embodiment of the present invention, the top of each layer of the condensation pipes 511 is provided with a refrigerant inlet 515, the bottom thereof is provided with a refrigerant outlet 516, and the condensation pipes 511 extend in a winding manner in a direction from the refrigerant inlet 515 to the refrigerant outlet 516.

It can be understood that the condensation pipe 511 extends in a winding manner in a direction from the refrigerant inlet 515 to the refrigerant outlet 516, so as to increase a length of the condensation pipe 511 and increase a time for the refrigerant to flow in the condensation pipe 511, thereby increasing a heat exchange amount. Meanwhile, because the refrigerant has a large resistance when moving from bottom to top in the condensation pipes 511, in the embodiment of the present invention, the refrigerant inlets 515 of the condensation pipes 511 in each layer are disposed at the top, the refrigerant outlets 516 are disposed at the bottom, and the refrigerant flows from top to bottom in the condensation pipes 511 in each layer.

The refrigerant is input from the top of the condenser tube 511, and is output from the bottom, the top line spacing of the condenser tube 511 is larger, the corresponding refrigerant has high temperature, and the heat exchange speed is faster. The coolant temperature that the bottom line spacing of condenser pipe 511 is less corresponds is lower, through densely arranging main condenser pipe section 513, improves the difference in temperature of condenser pipe 511 and ambient air, is favorable to promoting heat exchange efficiency.

According to an embodiment of the present invention, the condenser 510 includes a plurality of condenser tubes 511 arranged side by side to increase the circulation length and time of the refrigerant in the condenser tubes 511.

In an embodiment of the present invention, the condenser 510 includes two layers of condensing tubes 511, which are a first condensing tube 512a and a second condensing tube 512b, respectively, and the first condensing tube 512a and the second condensing tube 512b are respectively formed with a refrigerant inlet 515 at the top and a refrigerant outlet 516 at the bottom. The first condensation pipe 512a and the second condensation pipe 512b are arranged side by side, and both of the refrigerant outlets 516 are located at the bottom.

In the related art, the refrigerant enters along the refrigerant inlet 515 of the first condensation pipe 512a, flows out along the refrigerant outlet 516 of the first condensation pipe 512a, enters the refrigerant outlet 516 of the second condensation pipe 512b at the closest distance, and finally flows out along the refrigerant inlet 515 of the second condensation pipe 512 b. In the scheme, the refrigerant undergoes a complete bottom-to-top flow process, the flow resistance of the refrigerant is large, and the heat exchange efficiency is low.

In the embodiment of the present invention, the refrigerant inlet of the first condensation pipe 512a is communicated with the outlet of the compressor 530 through the liquid inlet pipe 517a, the refrigerant outlet 516 of the first condensation pipe 512a is communicated with the refrigerant inlet 515 of the second condensation pipe 512b through the connection pipe 517, and the refrigerant outlet of the second condensation pipe 512b is communicated with the inlet of the evaporator 520 through the liquid outlet pipe 517 b. The refrigerant can still move from top to bottom in the second condensation pipe 512b, the resistance applied to the refrigerant during flowing is small, and the heat exchange efficiency of the condenser 510 is high.

In the embodiment of the present invention, the first condensation pipe 512a is disposed on a side of the second condensation pipe 512b opposite to the first container body, and the refrigerant sequentially flows through the first condensation pipe 512a and the second condensation pipe 512b, and the first condensation pipe 512a and the second condensation pipe 512b are attached to each other.

In an embodiment of the present invention, the connection pipe 517 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 510.

It will be appreciated that the space between adjacent main condenser tube sections 513 is a line spacing that allows air to flow through. The condenser 510 has a plurality of condensation tubes 511 arranged side by side, and when the condensation tubes 511 are arranged, the respective layers of condensation tubes 511 have an inside-outside order. The outer condensation pipe 511 can directly transfer heat to the air, and the inner condensation pipe 511 needs to transfer heat to the outer condensation pipe 511 before dissipating heat to the outside air.

In one embodiment of the present invention, each of the first and
