Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and particularly to a dehumidifier. Background Art

[0002] A heat pipe is an efficient heat transfer element designed based on the evaporation, condensation, and capillary phenomena of a working fluid, and has high heat transfer performance and high temperature uniformity. Heat pipes have now been widely used in high-efficiency heat transfer and mass transfer equipment in fields such as chemical engineering, power, metallurgy, light industry, glass, and ceramics, and research and applications in the field of air conditioning have also been continuously deepened.

[0003] Applying air-conditioning heat pipe technology to household dehumidifiers adds two processes, "equivalent humidity cooling of the return air at the evaporation end of the heat pipe" and "equivalent humidity heating of the supply air at the condensation section of the heat pipe", to the dehumidification model. The former effectively reduces the sensible heat ratio of the return air and increases the latent heat ratio of the main evaporator in the traditional dehumidification model, thereby improving the dehumidification capacity; the latter can increase the sensible heat ratio of the supply air, and a balance is required between "raising the supply air temperature back to a more comfortable temperature for the human body before blowing" and "raising the supply air temperature too much to cause discomfort to the human body".

[0004] The dehumidifying heat pipe mainly includes a separated heat pipe and an integral heat pipe. In the separated heat pipe, the evaporation end and the condensation end of the heat pipe are respectively located in front of and behind the main evaporator and are connected by a manifold. The evaporation end and the condensation end of the heat pipe are respectively composed of one or more serpentine pipes (or U-shaped pipes) and are combined with fins to form one or more heat exchange modules. The vapor-liquid two-phase working fluid in the heat pipe flows in the same direction. Sub-cooled liquid is likely to accumulate at the lower part of the evaporation end, and superheated gas is likely to concentrate at the upper part of the condensation end. Therefore, there are significant defects in uneven vapor-liquid distribution and refrigerant distribution.

[0005] In addition, the angle between the manifold and the horizontal direction can only vary within a certain range. To improve the condensate return effect, the separated heat pipe is generally a heat pipe with a liquid core, which has a complex structure and is cumbersome to manufacture, increasing the complexity of the heat pipe structure and production cost. Summary of the Invention

[0034] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0035] Reference will be made below to Figures 1-7 Describe the dehumidifier 100 according to an embodiment of the present invention, which includes a main evaporator 110, a plug-in assembly 120 and a heat pipe 130.

[0036] Specifically, as Figure 2 shown, the main evaporator 110 includes a first evaporator section 111 and a second evaporator section 112. The plug-in assembly 120 is connected between the first evaporator section 111 and the second evaporator section 112. That is, the first evaporator section 111 can be mechanically connected to the second evaporator section 112 through the plug-in assembly 120. In the description of the present invention, "the first feature" and "the second feature" may include one or more of such features.

[0037] As Figure 2 shown, the plug-in assembly 120 includes a first clamping plate 121 and a second clamping plate 122. The first clamping plate 121 is clamped to the end of the first evaporator section 111, and the second clamping plate 122 is clamped to the end of the second evaporator section 112. The first evaporator section 111 and the second evaporator section 112 can be connected together by clamping and connecting the first clamping plate 121 and the second clamping plate 122.

[0038] As Figure 1As shown, the heat pipe 130 can be an integral heat pipe 130. The heat pipe 130 can be multiple independent heat pipes 130. Each integral heat pipe 130 can be a thermosyphon, which independently completes a refrigeration cycle. The refrigerant only works between one cold source and one heat source, with vapor-liquid flowing in opposite directions. There is no subcooled liquid at the lower part of the evaporation section 131, and there is no problem of uneven vapor-liquid distribution. The independent circulation of multiple refrigerants constitutes the overall refrigerant circulation of the heat pipe 130, which can improve problems such as uneven liquid separation of the split heat pipe and insufficient working medium conveying force in the current dehumidifier 100, enabling the working medium to circulate as fully as possible and improving the heat exchange efficiency of the heat pipe 130 in the dehumidifier 100.

[0039] The heat pipe 130 can include an evaporation section 131, a condensation section 132, and an intermediate connection section 133 connected between the evaporation section 131 and the condensation section 132. Among them, the intermediate connection section 133 is clamped between the first clamping plate 121 and the second clamping plate 122. That is to say, the intermediate connection section 133 passes through the plugging assembly 120. It can be understood that while connecting the first evaporator section 111 and the second evaporator section 112, the plugging assembly 120 can also be used to support the intermediate connection section 133.

[0040] When the intermediate connection section 133 passes through the plugging assembly 120, one end of the intermediate connection section 133 is located on one side of the plugging assembly 120. The evaporation section 131 is connected to one end of the intermediate connection section 133. The evaporation section 131 is located on one side of the plugging assembly 120 and is opposite to the first evaporator section 111. The other end of the intermediate connection section 133 is located on the other side of the plugging assembly 120. The condensation section 132 is connected to the other end of the intermediate connection section 133. The condensation section 132 is located on the other side of the plugging assembly 120 and is opposite to the second evaporator section 112.

[0041] It should be noted that the heat pipe 130 can be arranged in the up-down direction, that is, the evaporation section 131 and the condensation section 132 are arranged in the up-down direction. In this way, the heat pipe 130 can also be a gravity-type heat pipe 130. The condensate can rely on gravity to return from the condensation section 132 to the evaporation section 131, so that a favorable directionality can be generated in the refrigeration cycle inside the heat pipe 130. Furthermore, there is no need to provide a wick inside the heat pipe 130, which simplifies the structure of the heat pipe 130, improves the manufacturing convenience of the heat pipe 130, and saves production costs. To improve the heat dissipation efficiency of the heat pipe 130, the heat pipe 130 can also be provided with multiple heat dissipation fins 134. In the description of the present invention, the meaning of "multiple" is two or more.

[0042] In addition, it should be noted that, under the connection action of the middle connection section 133 and the plug-in component 120, the evaporation section 131 is arranged on one side of the plug-in component 120, and the condensation section 132 is arranged on the other side of the plug-in component 120. At this time, the evaporation section 131 and the condensation section 132 are arranged staggeredly in the horizontal direction. Combining with the structure of the main evaporator 110, the air flow can be made to flow more smoothly. Compared with the separated heat pipe in the related art, the side areas of the evaporation section 131 and the condensation section 132 of the heat pipe 130 are only half of the side area of the main evaporator 110 respectively. This provides a reference idea for improving the problem of excessive air resistance of the dehumidifier 100 caused by adding the heat pipe 130 structure, that is, effectively solving the problem of excessive air resistance of the dehumidifier 100 caused by the heat pipe 130 structure.

[0043] For the dehumidifier 100 according to the embodiment of the present invention, by setting the integral heat pipe 130 and arranging the evaporation section 131 and the condensation section 132 staggeredly, on the one hand, it is convenient to optimize the layout of the heat pipe 130 by using the integral heat pipe 130 structure, and improve problems such as uneven refrigerant liquid separation and insufficient working medium conveying force in the heat pipe 130; on the other hand, the evaporation section 131 and the condensation section 132 are arranged staggeredly, and combined with the structure of the main evaporator 110, the air flow can be made to flow more smoothly.

[0044] It should be noted that the dehumidifier 100 may further include a main condenser 102, a fan 101, a bottom plate 103 and a top plate 104. Among them, the bottom plate 103 and the top plate 104 are arranged at intervals, the main condenser 102 and the main evaporator 110 are arranged between the bottom plate 103 and the top plate 104, the fan 101 is mounted between the bottom plate 103 and the top plate 104, and in the air flow direction, the main condenser 102 is located between the fan 101 and the main evaporator 110. The main evaporator 110 may include one or more heat exchange tubes 114, and the heat exchange tubes 114 may include a plurality of first U-shaped tubes 113. Similarly, the heat pipe 130 may also include a plurality of second U-shaped tubes 136 connected in sequence. In order to facilitate the filling of the refrigerant in the heat pipe 130, a refrigerant filling port 135 may be provided at the end of the heat pipe 130.

[0045] According to some embodiments of the present invention, as Figure 3 、 Figures 7-8 shown, the end of the first clamping plate 121 that is clamped with the first evaporator section 111 has a first clamping groove 1212, and the heat exchange tube 114 at the end of the first evaporator section 111 is clamped in the first clamping groove 1212. Thus, the cooperation between the first clamping groove 1212 and the heat exchange tube 114 can be used to stably cooperate the first evaporator and the first clamping plate 121 together. Correspondingly, as Figures 4-6As shown in the figure, the end of the second clamping plate 122 that is clamped to the second evaporator section 112 has a second clamping groove 1222, and the heat exchange tube 114 at the end of the second evaporator section 112 is clamped in the second clamping groove 1222. Thus, the cooperation between the second evaporator and the second clamping plate 122 can be stably achieved by the cooperation of the second clamping groove 1222 and the heat exchange tube 114.

[0046] In order to improve the stability of the cooperation between the first clamping plate 121 and the first evaporator section 111, in some examples, such as Figure 8 As shown in the figure, the first clamping plate 121 extends a first protective plate 1213 towards the first evaporator section 111. The first protective plate 1213 shields at least part of the outer surface of the first evaporator, and the height of the first protective plate 1213 is 3 - 5 mm. Similarly, in order to improve the stability of the cooperation between the second clamping plate 122 and the second evaporator section 112, in some examples, such as Figure 6 As shown in the figure, the second clamping plate 122 extends a second protective plate 1223 towards the second evaporator section 112. The second protective plate 1223 shields at least part of the outer surface of the second evaporator, and the height of the second protective plate 1223 is 3 - 5 mm.

[0047] Such as Figure 4 、 Figure 8 As shown in the figure, in some embodiments, during the refrigeration process of the second evaporator section 112, condensed water is likely to be generated. In order to facilitate the discharge of the condensed water, the first clamping plate 121 has a first drain hole 1214, the second clamping plate 122 has a second drain hole 1224, and the second drain hole 1224 is communicated with the first drain hole 1214 through a connecting pipe 1215. Thus, the condensed water can flow through the second drain hole 1224, the connecting pipe 1215, and the first drain hole 1214 for easy discharge. Further, the connecting pipe 1215 extends from the end face of the second clamping plate 122 towards the first clamping plate 121, and at least part of the connecting pipe 1215 is inserted into the first drain hole 1214. The connecting pipe 1215 is a tapered pipe, which facilitates the insertion of the connecting pipe 1215 into the first drain hole 1214.

[0048] According to some embodiments of the present invention, such as Figure 4 、 Figure 5 As shown in the figure, the first clamping plate 121 has a first clamping portion 1216, such as Figure 7As shown, the second card board 122 has a second engaging portion 1225. The first engaging portion 1216 engages with the second engaging portion 1225, whereby the first card board 121 and the second card board 122 can be engaged together, and further the first evaporator section 111 and the second evaporator section 112 can be installed together. For example, one of the first engaging portion 1216 and the second engaging portion 1225 is an engaging protrusion, and the other is an engaging groove. Thus, the first card board 121 and the second card board 122 can be connected together by using the structure of the engaging protrusion and the engaging groove, which can not only simplify the structures of the first card board 121 and the second card board 122, but also improve the connection stability therebetween.

[0049] Furthermore, as Figure 4 , Figure 6 shown, the second card board 122 has an extension leg 1226. The extension leg 1226 extends towards the first card board 121. The extension leg 1226 includes a first leg 1227 and a second leg 1228 which are oppositely arranged. The first card board 121 is located between the first leg 1227 and the second leg 1228. Second engaging portions 1225 are provided at the ends of both the first leg 1227 and the second leg 1228. Thus, the first card board 121 can be stably defined between the first leg 1227 and the second leg 1228.

[0050] To facilitate the cooperation between the first card board 121 and the second card board 122, in some examples, as Figure 7 shown, the end face of the first card board 121 facing the second card board 122 has a first fitting groove 1217. As Figure 5 shown, the end face of the second card board 122 facing the first card board 121 has a second fitting groove 1229. The second fitting groove 1229 and the first fitting groove 1217 are opposite to each other and define an installation space for defining the intermediate connection section 133.

[0051] As Figure 3 shown, the angle between the intermediate connection section 133 and the horizontal plane is an acute angle. It should be noted that when the heat pipe 130 is arranged in the up-down direction, the angle between the intermediate connection section 133 and the horizontal plane is an acute angle α, and α is less than 90°. Correspondingly, in order to match the installation space with the intermediate connection section 133, the extending direction of the installation space can be made to extend along with the intermediate connection section 133. At this time, the angle between the end face of the first card board 121 facing the second card board 122 and the horizontal plane is α, and the angle between the end face of the second card board 122 facing the first card board 121 and the horizontal plane is α.
