Therefore, industrial dehumidifiers are a very important part of production operations.

[0003] The working principle of industrial dehumidifier is that the fan draws humid air into the machine, passes through the heat exchanger, and the water molecules in the air condense into water droplets.

The heat dissipation assembly is used in a dehumidification device and is installed below the evaporator and condenser of the dehumidification device to use condensed water to cool the heat sink. The structure and working principle of the heat dissipation assembly are described in detail below in conjunction with the drawings in the specification.

[0036] Reference Figure 1 and Figure 2An embodiment of the present invention provides a heat dissipation component, including a bracket 10, a water receiving member 20 and a water collecting member 30, wherein the bracket 10 is provided with an installation area 12, and the installation area 12 is used to install a heat sink 51; the water receiving member 20 is fixedly mounted on the bracket 10 and located on the upper side of the installation area 12, and the water receiving member 20 is used to receive condensed water, and a water sprinkling hole 23 is opened on the water receiving member 20; the water collecting member 30 is fixedly mounted on the bracket 10 and located on the lower side of the installation area 12; wherein the condensed water drips from the water sprinkling hole 23, passes through the heat sink 51 and flows to the water collecting member 30.

[0037] First of all, it should be noted that the bracket 10, the water receiving part 20 and the water collecting part 30 can be integrally formed parts. If the main features of the water receiving tray are difficult to be integrally formed due to mold design or efficiency issues, the parts can be split according to the actual processing conditions of the mold, and connected by snaps or screws to form an assembly. For example, a plurality of snap positions are provided on the bracket 10, and the water receiving part 20 and the water collecting part 30 are snapped into the snap positions to complete the assembly and form a heat dissipation assembly. The specific structure is selected according to actual needs.

[0038] Reference Figure 3 and Figure 4 In this embodiment, the bracket 10 includes a support plate 11, and the support plate 11 has two side surfaces opposite to each other, namely a heat dissipation side 101 and an electrical side 102. The heat dissipation side 101 is used to fix and install the water receiving member 20 and the water collecting member 30, and the electrical side 102 is used to fix and install the electrical box. The electrical box has a frequency conversion controller 50, and the controller 50 includes a main board 52 and a heat sink 51. The heat sink 51 is arranged on the main board 52, and the heat sink 51 has a plurality of heat dissipation fins arranged at intervals. The installation area 12 is arranged on the support plate 11, and the installation area 12 is a heat dissipation port that runs from the electrical side 102 to the heat dissipation side 101. When the main board 52 is installed on the electrical side 102 of the support plate 11, the heat dissipation fins of the heat sink 51 can pass through the heat dissipation port and extend to the heat dissipation side 101. Therefore, the controller 50 is separated on the electrical side 102 by the support plate 11, and the water receiving part 20, the heat sink 51, and the water collecting part 30 are separated on the heat dissipation side 101, so that condensed water droplets on the heat dissipation side 101 can be blocked from splashing onto the controller 50, which means that it can achieve waterproof effect while also achieving efficient water cooling and heat dissipation.

[0039] Specifically, the water receiving member 20, the heat sink 51 and the water collecting member 30 are arranged in sequence from top to bottom on the bracket 10, that is, the water receiving member 20 is located in the upper layer, the heat sink 51 is located in the middle layer, and the water collecting member 30 is located in the lower layer. The heat dissipation assembly of this embodiment is arranged below the evaporator 60 and the condenser 70 of the dehumidifier, and the water receiving member 20 is located directly below the evaporator 60 and the condenser 70 to receive the condensed water falling from the evaporator 60 and the condenser 70. Since the water receiving member 20 is provided with a water sprinkling hole 23, the condensed water received by the water receiving member 20 will drip from the water sprinkling hole 23 to the heat sink 51 under the action of gravity, wherein the heat dissipation fins of the heat sink 51 are arranged at intervals, and a heat dissipation channel is formed between adjacent heat dissipation fins, and the two ends of the heat dissipation channel are respectively facing the water receiving member 20 and the water collecting member 30. When the condensed water drips from the water sprinkling hole 23 to the heat dissipation fin, it can flow along the heat dissipation channel to the water collecting member 30. The condensed water with a relatively low temperature is used to absorb heat and cool the heat sink 51, thereby achieving the effect of water cooling. Compared with the heat dissipation method of hot air, the heat dissipation efficiency and heat dissipation effect are greatly improved, thereby ensuring the normal operation of the dehumidifier.

[0040] In one embodiment, the water receiving member 20 includes a water receiving trough body 21, and the water sprinkling hole 23 is provided at the bottom and / or the wall of the water receiving trough body 21. Specifically, the water receiving trough body 21 is an elongated trough body with a certain width as a whole, and one side of the trough body is fixed to the bracket 10. The notch of the water receiving trough body 21 is directly opposite to the bottom of the evaporator 60 and the condenser 70, and the width of the trough body is equivalent to the width of the evaporator 60 and the condenser 70, so as to fully receive the condensed water falling from the evaporator 60 and the condenser 70. The shape of the water sprinkling hole 23 can be circular, rectangular, or star-shaped, and the number of the water sprinkling holes 23 can also be multiple. The shape and number of the water sprinkling holes 23 are not limited in this embodiment. The water sprinkling hole 23 can be provided on the groove wall of the water receiving trough body 21. After the water receiving trough body 21 receives a certain amount of condensed water, when the water level reaches the water sprinkling hole 23 located on the groove wall, the condensed water can flow out from the water sprinkling hole 23 and fall along the groove wall of the water receiving trough body 21. The water sprinkling hole 23 is provided on the groove wall so that a certain amount of condensed water can be stored before flowing out, which plays a role of delaying heat dissipation and adjusting the heat dissipation speed. The water sprinkling hole 23 can also be provided on the groove bottom of the water receiving trough body 21. The condensed water received by the water receiving trough body 21 directly drips from the water sprinkling hole 23 at the groove bottom. The condensed water can be directly cooled by water, which plays a role of rapid heat dissipation and has a fast heat dissipation speed.

[0041] Reference Figure 5AIn this embodiment, the water receiving trough body 21 is provided with a dripping surface 22 and a diversion slope 24. The bottom of the water receiving trough body 21 is concave to form the dripping surface 22 and the diversion slope 24 adjacent to the dripping surface 22. The diversion slope 24 is inclined to the dripping surface 22, and the dripping hole 23 is opened on the dripping surface 22. Specifically, since the water receiving trough body 21 is an oblong trough body as a whole, the bottom of the water receiving trough body 21 is also oblong. The bottom of the water receiving trough body 21 is generally low in the middle and high on both sides, specifically an inverted trapezoid. The low area in the middle is the dripping surface 22, and the high areas on both sides are the guide slopes 24. The two sides of the dripping surface 22 are respectively connected to two guide slopes 24, and the guide slopes 24 on both sides are inclined to the middle dripping surface 22. The dripping holes 23 are opened on the dripping surface 22. Therefore, the condensed water received in the water receiving trough body 21 is drained to the dripping surface 22 through the guide slopes 24, and the condensed water drips from the dripping holes 23 on the dripping surface 22, which is convenient for the dripping of the condensed water.

[0042] Continue to refer to Figure 5A In a specific implementation, the water sprinkling holes 23 are provided in a plurality, and the plurality of water sprinkling holes 23 are distributed in an array on the sprinkling surface 22. For example, the water sprinkling holes 23 are provided in three rows, each row is provided with ten water sprinkling holes 23, each row of water sprinkling holes 23 is arranged along the length direction of the water receiving tank body 21, and the three rows of water sprinkling holes 23 are distributed all over the sprinkling surface 22. Through the array layout, condensed water can drip from each water sprinkling hole 23 on the sprinkling surface 22, and the sprinkling area is large, so more heat dissipating fins can be water-cooled and the heat dissipation efficiency is improved.

[0043] Reference Figure 5B , further, the water receiving member 20 further includes a supporting rib 25, the supporting rib 25 being connected to the water receiving trough body 21 and being suspended to the notch of the water receiving trough body 21. In this embodiment, there are two supporting ribs 25, namely, a first supporting rib 25 and a second supporting rib 25. Since the water receiving trough body 21 is flat and long as a whole, one end of the first supporting rib 25 is connected to a short side edge of the notch of the water receiving trough body 21, and the other end of the first supporting rib 25 extends toward the middle of the notch, and the entire first supporting rib 25 is suspended to the notch, so that the first supporting rib 25 can support the evaporator 60 or the condenser 70 located directly above the notch. Similarly, one end of the second supporting rib 25 is connected to the other short side edge of the notch of the water receiving trough body 21, and the other end of the second supporting rib 25 extends toward the middle of the notch, and the entire second supporting rib 25 is suspended to the notch, so that the second supporting rib 25 can support the evaporator 60 or the condenser 70 located directly above the notch. By providing the supporting ribs 25 , the structural strength of the evaporator 60 and the condenser 70 can be improved.

[0044] Reference Figure 2 and Figure 3In one embodiment, the heat dissipation assembly further includes a baffle 40, which is fixed on the bracket 10 and is located between the water receiving member 20 and the mounting area 12. Specifically, the baffle 40 is fixed on the heat dissipation side 101 of the support plate 11, and the baffle 40 protrudes from the support plate 11 and is located above the heat sink 51. The length of the baffle 40 is greater than the width of the mounting area 12, that is, the baffle 40 can completely block the upper edge of the heat sink 51, and the waterproof effect is good. The width of the baffle 40 is less than the length of the heat dissipation fins to avoid blocking the condensed water from dripping onto the heat dissipation fins. For example, the width of the baffle 40 is one-fifth of the length of the heat dissipation fins. The baffle 40 is fixed on the support plate 11 to block the heat sink, in order to prevent the condensed water from flowing along the support plate 11 to the mainboard 52, play a role in splashproof and water-proofing, and ensure electrical safety.

[0045] Reference Figure 3 , further, the side of the baffle 40 facing the water receiving member 20 is an inclined surface 41. Specifically, the cross section of the baffle 40 is a right triangle, one right angle side of the triangle is attached to the support plate 11, and the other right angle side is located above the heat sink 51, and the hypotenuse is the inclined surface 41. The inclined surface 41 is inclined downward, and when the condensed water drops onto the inclined surface 41, it can slide along the inclined surface 41 onto the heat sink 51, ensuring the amount of water sprayed on the heat sink 51, making full use of all the condensed water for water cooling, and improving the utilization rate of the condensed water.

[0046] Reference Fig. 6A , Figure 6B and Figure 6C In one embodiment, the water collecting member 30 includes a water collecting tank body 31 and a drain pipe 32, and the drain pipe 32 is connected to the water collecting tank body 31. Specifically, the water collecting tank body 31 is fixed to the heat dissipation side 101 of the support plate 11, and the notch of the water collecting tank body 31 is directly opposite to the bottom of the heat sink 51. The water collecting tank body 31 is used to collect condensed water flowing down from the heat sink 51. The condensed water in the water collecting tank body 31 is discharged to the outside of the dehumidifier through the drain pipe 32. Among them, one end of the drain pipe 32 is connected to the water collecting tank body 31, and the other end extends to the outside of the water collecting tank body 31. The drain pipe 32 is connected to the water collecting tank body 31, and the drain pipe 32 is connected to the water collecting tank body 31, and the drain pipe 32 is connected to the lowest point of the water collecting tank body 31, so as to ensure that all the condensed water in the water collecting tank body 31 can be discharged smoothly, and to ensure that there is no accumulation of condensed water in the dehumidifier.

[0047] Reference Figure 6BIn this embodiment, the groove wall of the water collecting tank body 31 gradually expands from the groove bottom of the water collecting tank body 31 toward the groove opening to form a water receiving surface 33 on the groove wall. Specifically, the water receiving surface 33 is an outwardly expanding fan-shaped water receiving surface 33. The outwardly expanding fan-shaped water receiving surface 33 increases the groove opening of the water collecting tank body 31. By using the outwardly expanding fan-shaped water receiving surface 33, on the one hand, the increase in the groove opening can increase the water receiving area, and all the condensed water flowing down from the heat sink 51 can be collected to avoid the condensed water from splashing out. On the other hand, since the fan-shaped water receiving surface 33 gradually expands from the groove bottom to the groove opening, from the cross-section thereof, the water receiving surface 33 is an inclined surface 41, which is conducive to the condensed water flowing along the water receiving surface 33 to the groove bottom of the water collecting tank body 31, so that the condensed water can be discharged from the drain pipe 32 connected to the tank body.

[0048] Reference Figure 7 , further, the projection area of ​​the notch of the water collecting trough body 31 covers the water sprinkling hole 23. Specifically, after the notch of the water collecting trough body 31 is expanded outward, the projection area of ​​the notch can completely cover the water sprinkling hole 23, so that the condensed water dripping from the water sprinkling hole 23 can be collected by the water collecting trough body 31, and the condensed water is prevented from dripping to other locations. In this embodiment, the projection area of ​​the notch of the water collecting trough body 31 is larger than the area of ​​the sprinkling surface 22, and the projection area of ​​the notch of the water collecting trough body 31 completely covers the sprinkling surface 22, so that the sprinkling hole 23 on the sprinkling surface 22 is completely covered, so that the water collecting trough body 31 can completely catch the condensed water dripping from the sprinkling hole 23 and the heat sink 51.

[0049] Reference Figure 1-Figure 4 The embodiment of the present invention further provides a dehumidification device, characterized in that it includes: an evaporator 60, a condenser 70, a controller 50 and a heat dissipation component, the heat dissipation component is the heat dissipation component described in the above embodiment, and the heat dissipation component includes a bracket 10, a water receiving member 20 and a water collecting member 30. The bracket 10 is provided with an installation area 12, and the installation area 12 is used to install a heat sink 51; the water receiving member 20 is fixed on the bracket 10 and located on the upper side of the installation area 12, the water receiving member 20 is used to receive condensed water, and a water sprinkling hole 23 is opened on the water receiving member 20; the water collecting member 30 is fixed on the bracket 10 and located on the lower side of the installation area 12; wherein the condensed water drips from the water sprinkling hole 23 through the heat sink 51 and flows to the water collecting member 30. The controller 50 includes a main board 52 and a heat sink 51 disposed on the main board 52. The heat sink 51 is installed in the installation area 12. The main board 52 is installed on the side of the bracket 10 facing away from the water receiving member 20. The evaporator 60 and the condenser 70 are located on the upper side of the water receiving member 20. The water receiving member 20 is used to receive condensed water dripping from the evaporator 60 and the condenser 70. The heat dissipation assembly has been described in detail in the above embodiment and will not be described again here.

[0050] When the dehumidifier is turned on, the evaporator 60 generates low-temperature condensed water when it meets the humid air. After the condensed water drips onto the water receiving part 20 due to gravity, it is drained through the water sprinkling holes 23 opened on the water receiving part 20 and sprinkled onto the heat sink 51 of the controller 50, thereby achieving a high-efficiency water-cooling effect on the heat sink 51 of the controller 50; finally, the condensed water flowing down through the heat sink 51 is collected by the water collecting part 30 under the water receiving part 20, and is discharged to the outside of the machine through the drain pipe 32 provided on the water collecting part 30, thereby ensuring that no condensed water accumulates in the machine.

[0051] By implementing this embodiment, the heat dissipation component is arranged below the evaporator 60 and the condenser 70, and the condensed water falling from the evaporator 60 and the condenser 70 is used for water cooling and heat dissipation. The water receiving part 20, the heat sink 51 and the water collecting part 30 are arranged in layers and intervals on the bracket 10 in sequence, and the water receiving part 20 receives the falling condensed water, and the water receiving part 20 is provided with a water spraying hole 23, and the condensed water drips from the water spraying hole 23 onto the heat sink 51, and the heat sink 51 is water-cooled and cooled. After passing through the heat sink 51, the condensed water flows into the water collecting part 30, and is collected by the water collecting part 30. The condensed water in the water collecting part 30 is finally discharged through the drain pipe 32. In this way, the condensed water generated by the evaporator 60 and the condenser 70 is cleverly utilized, and the condensed water is sprayed onto the heat sink 51 to achieve a water cooling effect, effectively reducing the temperature of the variable frequency industrial dehumidifier controller 50, greatly improving the cooling efficiency, and improving safety and comfort.
