Description

Technical Field

[0001] The invention belongs to the technical field of dehumidification, and in particular relates to an external heat dissipation type condensing dehumidifier and a dehumidification method. Background Art

[0002] A dehumidifier is a device that uses thermodynamic principles and different technologies to reduce the humidity in the air. It is commonly found in homes and commercial places to remove excess moisture from the air and improve indoor air quality. Condensing dehumidifiers are one of the common types. They use a refrigerant cycle to cool the water vapor in the air, thereby condensing the moisture and discharging it.

[0003] In condensing dehumidifiers, refrigerants play a vital role. These refrigerants include Freon, ammonia, hydrofluorocarbons, etc. They can be in gaseous or liquid state at different pressures and temperatures, and reduce the moisture content in the air by absorbing and releasing heat. The entire cycle includes the phase change process of the refrigerant at high temperature and high pressure and low temperature and low pressure, and uses its thermodynamic properties to complete the dehumidification process.

[0004] Although condensing dehumidifiers perform well in dehumidification, there are some challenges with the heat dissipation efficiency of current products on the market. The heat dissipation efficiency is not high, especially when the ambient temperature is too high, the heat dissipation power is insufficient to meet the demand. This situation may cause the dehumidifier to have difficulty operating in a high temperature environment, or even overheat, affecting the performance and life of the equipment.

[0005] One of the main reasons for insufficient heat dissipation efficiency is that the heat dissipation system design is not optimized enough. In high temperature environments, dehumidifiers need a more effective heat dissipation system to maintain a stable operating temperature. Some current dehumidifiers may not fully consider the challenges of high temperature environments to the heat dissipation system in their designs, resulting in poor heat dissipation efficiency. In addition, there may be problems such as insufficient radiator area or unreasonable air duct design, which will affect the heat dissipation efficiency of the dehumidifier.

[0006] In summary, how to provide a compression dehumidifier that is conducive to improving efficiency and occupies a small area is a technical problem that urgently needs to be solved. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an external heat dissipation condensing dehumidifier and a dehumidification method. By providing a first heat dissipation part on the outer shell in cooperation with a second heat dissipation part in the condensing device, the heat dissipation efficiency can be improved, which helps to maintain a stable dehumidification performance.

[0008] The present invention provides an external heat dissipation condensing dehumidifier, comprising an air inlet and an outer shell, wherein the outer shell is provided with a first heat dissipation part; A condensation device for cooling air to form condensed water is provided in the outer shell; The condensing device comprises a second heat dissipating part and a first heat absorbing part; Condensation medium flows through the first heat dissipation part, the second heat dissipation part and the first heat absorption part; It also includes a compressor, which is arranged in the outer shell and / or on the outer shell and is respectively connected to the first heat dissipation part, the second heat dissipation part and the first heat absorption part.

[0009] Furthermore, the condensing device has a double-layer structure, including an outer layer area and an inner layer area from the outside to the inside; the second heat dissipation part is arranged in the outer layer area; and the first heat absorption part is arranged in the inner layer area.

[0010] Furthermore, it also includes a spare condensing medium bin for accommodating condensing medium, and the condensing medium bin is at least connected to the aforementioned first heat dissipation part, and is used to input condensing medium to the first heat dissipation part.

[0011] Further, the first heat dissipation part includes a first heat dissipation pipe and / or a second heat dissipation pipe; Wherein, the internal cavity area of ​​the second heat dissipation tube is larger than the internal cavity area of ​​the first heat dissipation tube.

[0012] Further, the second heat dissipation part includes a third heat dissipation tube and / or a fourth heat dissipation tube; The inner cavity area of ​​the fourth heat dissipation tube is larger than the inner cavity area of ​​the third heat dissipation tube.

[0013] Furthermore, the outer shell also includes a control unit; the control unit is used to collect internal and external environmental parameters, compare them with a preset threshold range, and start or shut down the first heat dissipation unit according to the comparison result.

[0014] Further, the first heat dissipation portion is connected to the second heat dissipation portion; Alternatively, the first heat dissipation portion and the second heat dissipation portion are not connected; Alternatively, the first heat dissipation portion and the second heat dissipation portion may be selectively connected.

[0015] Furthermore, the outer shell includes a frame, and a movable panel is detachably mounted on the side of the frame; A fixed panel is fixedly mounted on the frame; the first heat dissipation portion is mounted in the movable panel, and / or the first heat dissipation portion is mounted in the fixed panel.

[0016] The present invention also provides a dehumidification method using any one of the external heat dissipation condensing dehumidifiers described above, comprising the following steps: when the second heat dissipation part is in operation, starting the first heat dissipation part to perform auxiliary heat dissipation.

[0017] Furthermore, it also includes collecting internal and external environmental parameters, comparing them with a preset threshold range, and starting or shutting down the first heat dissipation unit according to the comparison result.

[0018] Due to the adoption of the above technical solution, the present invention has the following advantages and positive effects compared with the prior art, as an example: By additionally setting up a first heat dissipation part on the outer shell in cooperation with the second heat dissipation part included in the condensing device, heat can be dissipated more effectively, the heat dissipation efficiency can be improved, ensuring effective operation under different external environments, maintaining stable dehumidification performance, meeting the dehumidification needs in different scenarios, having a wider range of applications, and avoiding the risk of overheating and damage of equipment in high temperature environments, thereby extending the service life of the dehumidifier and reducing maintenance costs.

DETAILED DESCRIPTION

[0025] The technical solution disclosed in the present invention is described in detail below in conjunction with specific embodiments.

[0026] Techniques and methods known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques and methods should be considered part of the specification. In all examples shown and discussed herein, any specific value should be interpreted as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0027] The present invention provides an external heat dissipation condensing dehumidifier 100, including an air inlet 110 for air to enter. The structure of the air inlet 110 is prior art and will not be elaborated again.

[0028] The external heat dissipation condensing dehumidifier 100 further includes an outer shell 200 .

[0029] The outer shell 200 is provided with a condensation device 300 for cooling air to form condensed water.

[0030] The condensing device 300 includes a second heat dissipating portion 340 and a first heat absorbing portion 320 .

[0031] Condensation medium flows through both the second heat dissipation portion 340 and the first heat absorption portion 320 .

[0032] As shown in the figure, it comprises an outer shell 200 , and a first heat dissipation portion 210 is disposed on the outer shell 200 .

[0033] like Figure 1 As shown, preferably, the condensing device 300 has a double-layer structure, including an outer layer area 330 and an inner layer area 310 from the outside to the inside.

[0034] The second heat dissipation portion 340 is disposed in the outer region 330 ; the first heat absorption portion 320 is disposed in the inner region 310 .

[0035] The second heat dissipation part 340 is surrounded by the first heat absorption part 320 through the inner and outer double-layer structure.

[0036] The first heat absorbing portion 320 includes a pipe laid in the inner layer region 310 .

[0037] The second heat dissipation portion 340 includes a pipe laid in the outer region 330 .

[0038] The pipes are usually copper pipes, but aluminum pipes and stainless steel pipes can also be used.

[0039] The structure of a pipeline can include: The use of spiral pipes can increase the surface area of ​​the pipes and improve the heat absorption efficiency.

[0040] The pipeline can be designed as a multi-channel pipeline, which can increase the surface area of ​​heat exchange and improve the heat absorption effect.

[0041] The condensation medium entering the second heat dissipation part 340 is in liquid state, circulates in the second heat dissipation part 340, releases heat, and the temperature of the liquid drops, thereby completing cooling.

[0042] The condensation medium entering the first heat absorption part 320 is in liquid state. The condensation medium in the circulation process absorbs heat and is converted from liquid state to gas state.

[0043] The air entering through the air inlet 110 contacts the first heat absorbing portion 320 located in the inner layer, and under the action of the liquid condensation medium, the air is cooled and condensed into water.

[0044] The condensed medium in the first heat absorbing part 320 absorbs heat and is converted from liquid to gas. The gaseous condensed medium then enters a compressor (not shown in the figure), which compresses and liquefies the gaseous condensed medium and then introduces it into the second heat dissipating part 340, and the above process is repeated.

[0045] In particular, the outer shell 200 is provided with a first heat dissipation portion 210, which is not provided in the condensing device 300 covered by the outer shell 200, but is directly provided on the outer shell 200. Figure 2 As shown, the portion of the outer shell 200 where the first heat dissipation portion 210 is disposed may be relatively protruding from the surface of the remaining portion of the outer shell 200 where the first heat dissipation portion 210 is not disposed, or, as shown in FIG. Figure 3 As shown, the first heat dissipation portion 210 is disposed adjacent to and below the outer surface of the outer shell 200 .

[0046] Similar to the second heat dissipation portion 340 , the first heat dissipation portion 210 includes a pipe laid inside the outer shell 200 .

[0047] The first heat dissipation part 210 includes a first heat dissipation pipe and / or a second heat dissipation pipe; Wherein, the internal cavity area of ​​the second heat dissipation tube is larger than the internal cavity area of ​​the first heat dissipation tube.

[0048] When both are set, first, the first heat dissipation pipe is usually used to assist heat dissipation, and its internal cavity area is relatively small. When the dehumidifier is working, it discharges part of the heat from the refrigeration system to achieve a cooling effect. This helps to maintain a stable temperature inside the refrigeration system, prevent overheating and ensure the normal operation of the system.

[0049] Relatively speaking, the second heat dissipation pipe has a larger internal cavity area and is usually used for the main heat dissipation task. The second heat dissipation pipe assumes the main function of heat dissipation of the second heat dissipation part 340, and provides a larger heat dissipation surface area through its larger internal cavity area, so as to dissipate heat more effectively. This enables the second heat dissipation pipe to dissipate the heat generated by the dehumidifier to the surrounding environment more efficiently, reduce the operating temperature of the device, and improve the overall heat dissipation effect.

[0050] Similarly, optionally, the second heat dissipation portion 340 includes a third heat dissipation tube and / or a fourth heat dissipation tube.

[0051] The inner cavity area of ​​the fourth heat dissipation tube is larger than the inner cavity area of ​​the third heat dissipation tube.

[0052] By arranging the first heat dissipation part 210 on the outer shell 200, the outer shell 200 closer to the external environment has a heat dissipation function, which can increase the heat dissipation surface area, speed up the heat transfer speed, more effectively handle the humidity in the air, quickly reduce the relative humidity, and improve the heat dissipation efficiency and power, thereby more effectively responding to the heat dissipation needs in an environment where heat dissipation is difficult.

[0053] On the other hand, the heat dissipation components provided on the outer shell 200 can achieve more uniform heat distribution and dissipation, avoid local overheating, and help maintain a stable operating temperature of the device in a high temperature environment or in a long-term continuous operation scenario. It can effectively reduce the device temperature, reduce the risk of overheating, improve the stability and reliability of the device, and thus extend the life of the device.

[0054] The outer shell 200 further includes a control unit (not shown in the figure); the control unit is used to collect environmental parameters and compare them with a preset threshold range, and start or shut down the first heat dissipation unit 210 according to the comparison result.

[0055] Internal and external environmental parameters mainly refer to key factors that may affect the heat dissipation efficiency, including but not limited to external environmental parameters such as temperature, humidity, air quality, and air pressure, as well as internal parameters of the outer shell 200, including but not limited to operating load, operating time, etc.

[0056] The control unit corresponding to the required settings includes a temperature sensor, a humidity sensor, an air quality sensor, an air pressure sensor, an energy consumption monitor, etc.

[0057] Taking the temperature sensor as an example, after the temperature sensor collects the external ambient temperature, the controller receives the collected result and compares it with the preset temperature threshold range. According to the comparison result, the control unit can make corresponding decisions, such as starting or shutting down the first heat dissipation unit 210 to adjust the operating state of the dehumidifier. If the ambient temperature exceeds the set range, the control unit may start the first heat dissipation unit 210 to help improve the heat dissipation power; conversely, if the temperature is within the set range, the control unit may shut down the first heat dissipation unit 210 and only run the condensing device 300 to save energy.

[0058] Similarly, high humidity may cause the air to contain more moisture, increasing the difficulty of heat dissipation. Excessive humidity may affect the heat dissipation efficiency of the dehumidifier. Therefore, humidity monitoring is also important. The humidity sensor is used to monitor the humidity level in the environment. The control unit receives the data collected by the humidity sensor and compares it with the preset humidity threshold range. According to the comparison result, it is determined whether the first heat dissipation unit 210 needs to be started to increase the heat dissipation power.

[0059] The energy consumption monitor is used to monitor the working load and duration of the dehumidifier. Long-term high-load operation may cause insufficient power of the dehumidifier, and at this time, the first heat dissipation unit 210 needs to be additionally started to supplement the power.

[0060] Of course, the control unit may also include a switch for the user to manually control the opening or closing of the first heat dissipation unit 210 .

[0061] The connection between the first heat dissipation part 210, the second heat dissipation part 340 and the compressor includes one of the following ways: First, the first heat dissipation part 210 and the second heat dissipation part 340 are interconnected and connected to the compressor, that is, the condensation medium can flow among the first heat dissipation part 210, the second heat dissipation part 340 and the compressor.

[0062] In another embodiment, the first heat dissipation portion 210 and the second heat dissipation portion 340 are not connected to each other, but are respectively connected to the compressor.

[0063] In another embodiment, if Figure 4 As shown, the first heat dissipation part 210 and the second heat dissipation part 340 can be selectively connected, and the gate 112 is provided at the connection between the two for control. In a specific implementation, the gate 112 can be set to open when the controller starts the first heat dissipation part 210, allowing the condensation medium to flow between the first heat dissipation part 210 and the second heat dissipation part 340, and to close when the controller turns off the first heat dissipation part 210.

[0064] Optionally, the heat dissipation condensation dehumidifier further includes a spare condensation medium bin for accommodating condensation medium, and the condensation medium bin is at least connected to the aforementioned first heat dissipation part 210 for inputting condensation medium into the first heat dissipation part 210 .

[0065] In the case where a spare condensing medium bin is provided, the compressor may not be directly connected to the first heat dissipation portion 210, but may be connected to the first heat dissipation portion 210 through the condensing medium bin. That is, the liquid condensing medium compressed and liquefied by the compressor is introduced into the spare condensing medium bin, and then transferred from the spare condensing medium bin to the first heat dissipation portion 210.

[0066] When the condensing medium bin is connected to the first heat dissipation part 210 and the second heat dissipation part 340, similarly, the condensing medium input to the second heat dissipation part 340 may come directly from the compressor or through the condensing medium bin.

[0067] The outer shell 200 includes a frame 500 , and a movable panel 510 is detachably mounted on a side of the frame 500 .

[0068] A fixed panel 520 is fixedly mounted on the frame 500 .

[0069] The first heat dissipation portion 210 is installed in the movable panel 510 , and / or the first heat dissipation portion 210 is installed in the fixed panel 520 .

[0070] The movable panel 510 on the first heat dissipation part 210 can be installed or removed as needed. According to different usage scenarios, the user can adjust the number of the first heat dissipation parts 210 on the external heat dissipation condensing dehumidifier 100 accordingly.

[0071] In a scenario where the heat dissipation requirement is relatively high, the first movable panel 510 is installed to increase the number of the first heat dissipation parts 210 . Otherwise, the first movable panel 510 is removed to reduce the number of the first heat dissipation parts 210 .

[0072] The first heat dissipation portion 210 is installed in the movable panel 510 , and / or the first heat dissipation portion 210 is installed in the fixed panel 520 .

[0073] The present invention further provides a dehumidification method using the external heat dissipation condensing dehumidifier 100 as described above, comprising the following steps: when the second heat dissipation part 340 is in operation, starting the first heat dissipation part 210 for auxiliary heat dissipation.

[0074] The method also includes collecting internal and external environmental parameters, comparing them with a preset threshold range, and starting or shutting down the first heat dissipation unit 210 according to the comparison result.
