Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, for example, to a heat exchange component and a refrigerator. Background Art

[0002] At present, the evaporative heat exchanger in the refrigerator absorbs a lot of heat during operation. During long-term operation, frost is easily condensed on the evaporative heat exchanger, which reduces the heat exchange effect of the evaporative heat exchanger and makes the refrigerator's operating power consumption higher.

[0003] A heat exchanger assembly, comprising a heat exchange tube, heat exchange fins, and a heating tube, is disclosed in the related art. The heat exchange fins are provided in multiple, spaced intervals; the heat exchange tube passes through and is fixedly connected to the multiple heat exchange fins; and the heating tube is disposed on the same side of the multiple heat exchange fins. Heat from the heating tube radiates to the multiple heat exchange fins and the heat exchange tube, melting any frost that has accumulated on the heat exchange tube and the multiple heat exchange fins. This ensures effective heat exchange between the heat exchange tube and the multiple heat exchange fins, reducing the refrigerator's operating power consumption.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] The heat transfer on the other side of the heat exchange fins is slower than that on the other side of the heating tube, which results in a longer defrosting time and higher energy consumption.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Utility Model Content

[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.

[0008] The embodiments of the present disclosure provide a heat exchange assembly and a refrigerator, which utilize a heat-conducting shield to accelerate heat conduction, allowing heat to be quickly transferred from one side of the heat exchanger to the other side, thereby reducing defrosting time and lowering energy consumption.

[0009] In some embodiments, a heat exchange assembly includes a heat exchanger, a heat conductive shield, and a heating plate. The heat conductive shield is connected to the heat exchanger and extends from one side of the heat exchanger to the other side opposite the heat exchanger. The heating plate is disposed on one side of the heat exchanger and connected to the heat conductive shield.

[0010] Optionally, the heat-conducting shield includes a first plate portion and a second plate portion. The first plate portion is connected to the heat exchanger and extends from one side of the heat exchanger to the other side of the heat exchanger; the second plate portion is connected to the first plate portion and is located on one side of the heat exchanger.

[0011] Optionally, the heat-conducting shield further includes a third plate portion, which is disposed on the other side of the heat exchanger and is connected to a portion of the first plate portion extending to the other side of the heat exchanger.

[0012] Optionally, two heat-conducting shields are provided, one of which is connected to one end of the heat exchanger, and the other is connected to the other end opposite to the heat exchanger.

[0013] Optionally, the heating plate is detachably connected to the heat-conducting shield.

[0019] The heat exchange assembly and refrigerator provided by the embodiments of the present disclosure can achieve the following technical effects:

[0020] The heating plate heats up, transferring heat to the heat-conducting shield.

[0039] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0041] Combine Figure 1 As shown, an embodiment of the present disclosure provides a heat exchange assembly, comprising: a heat exchanger 100, a heat conductive shield 200, and a heating plate 300. The heat conductive shield 200 is connected to the heat exchanger 100 and extends from one side of the heat exchanger 100 to the other side opposite to the heat exchanger 100; the heating plate 300 is disposed on one side of the heat exchanger 100 and connected to the heat conductive shield 200.

[0042] With the heat exchange assembly provided by the embodiments of the present disclosure, heating plate 300 generates heat, which is then transferred to heat-conducting shield 200. Because heat-conducting shield 200 extends from one side of heat exchanger 100 to the opposite side, the heat transfer rate is increased. When defrosting heat exchanger 100, the temperature rises faster when heating plate 300 is positioned opposite the other side of the heat exchanger 100, reducing defrosting time and energy consumption.

[0043] Specifically, the heat-conducting shield 200 is fixedly connected to the heat exchanger 100. In this way, the risk of relative shaking between the heat-conducting shield 200 and the heat exchanger 100 is reduced, and the operating noise is reduced.

[0044] Optionally, in the vertical direction, the length of the heating plate 300 is greater than or equal to one-half the length of the heat exchanger 100, and less than or equal to the length of the heat exchanger 100. Thus, when the length of the heating plate 300 is less than one-half the length of the heat exchanger 100, the length of the heating plate 300 in the vertical direction is smaller, and the range of heat radiation from the heating plate 300 is smaller, resulting in a longer time required for defrosting and higher energy consumption during operation. When the length of the heating plate 300 is greater than the length of the heat exchanger 100, the length of the heating plate 300 in the vertical direction is greater than the length of the heat exchanger 100, and a larger space is required for installation. Thus, it can be seen that the range in which the length of the heating plate 300 is greater than or equal to one-half the length of the heat exchanger 100 and less than or equal to the length of the heat exchanger 100 is more reasonable, the range of heat radiation from the heating plate 300 is larger, the time required for defrosting is reduced, and the space required for installation is relatively small.

[0045] Optionally, in the vertical direction, the length of the heating plate 300 is equal to five-sixths of the length of the heat exchanger 100. In this way, the heat radiation range of the heating plate 300 is relatively large, the time required for defrosting is reduced, and the space required for installation is relatively small.

[0046] Combine Figure 2 As shown, the heating plate 300 optionally includes a heat transfer plate 310 and a heating wire 320. The heat transfer plate 310 is connected to the heat conductive shield 200; the heating wire 320 is disposed inside the heat transfer plate 310. Thus, through the heating wire 320, heat is conducted to the heat transfer plate 310, which then transfers the heat to the heat conductive shield 200 and radiates heat to the surrounding area of ​​the heat transfer plate 310, thus covering a wider area and conducting heat more evenly.

[0047] Combine Figure 3As shown, optionally, the heat-conducting shield 200 includes a first plate portion 210 and a second plate portion 220. The first plate portion 210 is connected to the heat exchanger 100 and extends from one side of the heat exchanger 100 to the other side of the heat exchanger 100; the second plate portion 220 is connected to the first plate portion 210 and is located on one side of the heat exchanger 100. In this way, the second plate portion 220 is connected to the heating plate 300, and the contact area with the heating plate 300 is larger, and the heat from the heating plate 300 is transferred to the second plate portion 220 more quickly. The heat from the second plate portion 220 is then transferred from the first plate portion 210 to the other side of the heat exchanger 100, which increases the temperature rise on that side, reduces the time required for defrosting, and reduces energy consumption during operation.

[0048] Specifically, the plane where the first plate portion 210 is located is perpendicular to the plane where the second plate portion 220 is located.

[0049] Specifically, the heat transfer plate 310 is connected to the second plate portion 220. In this way, the heat transfer plate 310 is connected to the second plate portion 220, the contact area is relatively large, the heat conduction speed is faster, the time required for defrosting is reduced, and the energy consumption of operation is reduced.

[0050] Combine Figure 4 As shown, optionally, the heat-conducting shield 200 further includes: a third plate portion 230. The third plate portion 230 is arranged on the other side of the heat exchanger 100, and the third plate portion 230 is connected to the portion of the first plate portion 210 extending to the other side of the heat exchanger 100. In this way, the heat of the first plate portion 210 is conducted to the third plate portion 230, and the third plate portion 230 radiates heat to the surroundings in the form of thermal radiation. In other words, heat is radiated to the other side of the heat exchanger 100 opposite to the side where the heating plate 300 is arranged, and the area of ​​the third plate portion 230 is relatively large, the range of radiated heat is larger, and the temperature on this side increases faster, which reduces the time required for defrosting and reduces the energy consumption of operation.

[0051] Specifically, the plane of the third plate portion 230 is perpendicular to the plane of the first plate portion 210, and the plane of the third plate portion 230 is parallel to the plane of the second plate portion 220. In this way, the first plate portion 210, the second plate portion 220, and the third plate portion 230 can be combined into a C-shape, surrounding the heat exchanger 100. This allows the second and third plates 220, 230 to be relatively close to the heat exchanger 100, allowing the second and third plates 220, 230 to transfer heat to the heat exchanger 100 more quickly.

[0052] Optionally, two heat-conducting shields 200 are provided, one of which is connected to one end of the heat exchanger 100, and the other is connected to the opposite end of the heat exchanger 100. In this way, heat-conducting shields 200 are provided at both ends of the heat exchanger 100. The heating plate 300 heats the heat through the two heat-conducting shields 200, and conducts the heat to the other side of the heat exchanger 100 opposite to the side where the heating plate 300 is provided. The temperature on this side rises faster, and the heat conduction is more balanced, thereby reducing the time required for defrosting and lowering the energy consumption during operation.

[0053] Specifically, the two heat-conducting shielding plates 200 are symmetrically arranged.

[0054] Optionally, the heating plate 300 is detachably connected to the heat-conducting shield 200. This facilitates the removal of the heating plate 300 from the heat-conducting shield 200, making it easier to inspect and repair the heating plate 300 and the heat exchanger 100.

[0055] Specifically, the heat transfer plate 310 is detachably connected to the second plate portion 220 .

[0056] Combine Figure 5 and Figure 6 As shown, optionally, the heating plate 300 is connected to the heat-conducting guard plate 200 by a card plate 101 and / or a bolt 102. In this way, when the heating plate 300 is connected to the heat-conducting guard plate 200 by the card plate 101, the heating plate 300 can be slid out or inserted back between the card plate 101 and the heat-conducting guard plate 200, so that the heat-conducting guard plate 200 and the heating plate 300 can be quickly separated or installed, and the operation is relatively simple. When the heating plate 300 is connected to the heat-conducting guard plate 200 by the bolt 102, the connection between the heating plate 300 and the heat-conducting guard plate 200 is more secure and the connection stability is higher. When the heating plate 300 is connected to the heat-conducting guard plate 200 by the card plate 101 and the bolt 102, the number of screws used can be reduced, the time for installing and removing the screws can be reduced, and the stability of the connection can be guaranteed.

[0057] Optionally, thermal grease is provided between the heating plate 300 and the heat-conducting shield 200. Thus, by applying thermal grease between the heating plate 300 and the heat-conducting shield 200, the gap between the heating plate 300 and the heat-conducting shield 200 is filled, thereby improving the speed of heat conduction.

[0058] Combine Figure 7 As shown, a reflective layer 400 is optionally provided on a side wall of the heating plate 300 facing away from the heat exchanger 100. Thus, by providing the reflective layer 400 on the heating plate 300 to reflect the heat generated by the heating plate 300, more heat can be radiated or conducted toward the heat exchanger 100, thereby reducing heat loss, shortening the time required for defrosting, and lowering energy consumption during operation.

[0059] Specifically, the reflective layer 400 is aluminum foil.

[0060] Optionally, a heat insulating layer 500 is provided on a side wall of the heating plate 300 facing away from the heat exchanger 100. In this way, the heat insulating layer 500 reduces the heat transfer from the heating plate 300 back to the heat exchanger 100, thereby reducing heat loss.

[0061] Specifically, the heat insulating layer 500 is connected to a side wall of the reflective layer 400 facing away from the heat exchanger 100 .

[0062] Specifically, the thermal insulation layer 500 is aerogel felt.

[0063] Combine Figure 8 As shown, in some embodiments, the refrigerator 600 includes: a heat exchange component as described in the above embodiment.

[0064] In the refrigerator 600 provided by the embodiment of the present disclosure, since it includes the heat exchange assembly of the above-described embodiment, the heating plate 300 heats the refrigerator, and the heat is transferred to the heat-conducting shield 200. Since the heat-conducting shield 200 extends from one side of the heat exchanger 100 to the opposite side of the heat exchanger 100, the heat transfer rate is improved. When defrosting the heat exchanger 100, the temperature rises faster when the heating plate 300 is positioned on the opposite side of the heat exchanger 100, reducing the time required for defrosting and lowering energy consumption.

[0065] Optionally, refrigerator 600 further includes a controller 610. Controller 610 is disposed on one side of heating plate 300 and is configured to control the heating of heating plate 300. Thus, controller 610 controls heating plate 300 to activate or deactivate heating, thereby preventing prolonged heating of heating plate 300 from affecting the heat exchange performance of heat exchanger 100.

[0066] Optionally, the refrigerator 600 further includes a temperature sensor 620. The temperature sensor 620 is provided on one side of the heat exchanger 100 and is used to obtain the ambient temperature and send the ambient temperature to the controller 610. In this way, the ambient temperature around the heat exchanger 100 can be obtained through the temperature sensor 620.

[0067] Optionally, the controller 610 controls the heating plate 300 to heat, including: the controller 610 controls the heating plate 300 to heat intermittently. In this way, the intermittent heating of the heating plate 300 can ensure the defrosting effect while reducing the operating energy consumption of the heating plate 300.

[0068] In one embodiment, the controller 610 controls the heating plate 300 to perform intermittent heating, including: controlling the heating plate 300 to shut down after the heating plate 300 has been powered on for a first preset time; and controlling the heating plate 300 to resume heating after the heating plate 300 has been powered off for a second preset time. Thus, the heating plate 300 continues heating for the first preset time, raising the temperature around the heat exchanger 100 and melting frost on the heat exchanger 100. The heating plate 300 is then shut down for the second preset time, reducing energy consumption and preventing excessive temperatures. This also provides time for the melted frost to flow downward. The heating plate 300 is then switched on again for the first preset time. This intermittent heating process defrosts the heat exchanger 100 and prevents prolonged heating by the heating plate 300, which could overheat the heat exchanger 100 and affect the temperature of items stored in the refrigerator 600.

[0069] Optionally, the first preset time is 5 seconds.

[0070] Optionally, the second preset time is 8 seconds.

[0071] In another embodiment, the controller 610 controls the heating plate 300 to heat intermittently, including: when the temperature of the heating plate 300 is less than or equal to a first preset temperature, the controller 610 controls the heating plate 300 to be powered on for heating; when the temperature of the heating plate 300 is greater than or equal to a second preset temperature, the controller 610 controls the heating plate 300 to be powered off, stop heating, and cool down; wherein the second preset temperature is greater than the first preset temperature. In this way, after the heating plate 300 is heated to a temperature greater than the first preset temperature, the controller 610 controls the heating plate 300 to be powered off and stop heating, thereby reducing the energy consumption of the heating plate 300 and preventing the temperature from being too high. After the heating plate 300 cools for a period of time, when the temperature of the heating plate 300 is less than the second preset temperature, the heating plate 300 is controlled to be powered on for heating again. After the heating temperature of the heating plate 300 is greater than the first preset temperature, the controller 610 controls the heating plate 300 to stop heating. Such intermittent heating can make the temperature control more precise, reduce the power consumption of the heating plate 300, and heat the heat exchanger 100 to defrost, so as to avoid the heating plate 300 from heating for a long time continuously causing the temperature of the heat exchanger 100 to be too high, affecting the temperature of the items stored in the refrigerator 600.

[0072] Optionally, the first preset temperature is 60°C.

[0073] Optionally, the second preset temperature is 80°C.

[0074] Optionally, after the controller 610 controls the intermittent heating of the heating plate 300, the controller 610 further includes: obtaining real-time parameters, and controlling the intermittent heating operation of the heating plate 300 based on the magnitude relationship between the real-time parameters and preset parameters. In this way, the intermittent heating of the heating plate 300 is controlled to start the defrosting operation or stop the defrosting operation based on the magnitude relationship between the real-time parameters and the preset parameters.

[0075] In one embodiment, the controller 610 obtains real-time parameters and, based on the relationship between the real-time parameters and preset parameters, controls the intermittent heating operation of the heating plate 300 according to the relationship between the ambient temperature and a third preset temperature. Thus, when the ambient temperature is less than the third preset temperature, the heating plate 300 maintains intermittent heating to perform the defrosting operation. When the ambient temperature is greater than or equal to the third preset temperature, frost condensed on the heat exchanger 100 can be effectively removed, so the controller 610 controls the heating plate 300 to stop operating and exit the defrosting operation, promptly stopping the intermittent heating of the heating plate 300 and reducing energy consumption.

[0076] Optionally, the third preset temperature is 7°C.

[0077] Optionally, when the ambient temperature is greater than or equal to a third preset temperature, the heating plate 300 is powered off and the intermittent heating is stopped. Thus, when the ambient temperature is greater than the third preset temperature, frost condensed on the heat exchanger 100 can be effectively removed. Therefore, the controller 610 controls the heating plate 300 to stop operating and exit the defrosting operation, promptly stopping the intermittent heating of the heating plate 300 and reducing energy consumption.

[0078] In another embodiment, the controller 610 obtains real-time parameters and, based on the relationship between the real-time parameters and preset parameters, controls the intermittent heating operation of the heating plate 300 according to the relationship between the heating time and a third preset time. Thus, when the heating time is greater than or equal to the third preset time, frost condensed on the heat exchanger 100 can be effectively removed. Therefore, the controller 610 controls the heating plate 300 to stop defrosting, promptly stopping the intermittent heating operation of the heating plate 300 and reducing energy consumption.

[0079] Optionally, the third preset time is 60 minutes.

[0080] Optionally, when the heating time is greater than or equal to a third preset time, the heating plate 300 is powered off to stop intermittent heating. Thus, when the heating time is greater than or equal to the third preset time, frost condensed on the heat exchanger 100 can be effectively removed. Therefore, the controller 610 controls the heating plate 300 to stop operating and exit the defrosting operation, promptly stopping the intermittent heating of the heating plate 300 and reducing energy consumption.

[0081] Optionally, before the controller 610 controls the heating plate 300 to heat, the controller 610 further includes: controlling the heating plate 300 to heat to a fourth preset temperature. In this way, before the heating plate 300 performs intermittent heating, the controller 610 controls the heating plate 300 to preheat so that the temperature of the heating plate 300 reaches a temperature range for intermittent heating of the heating plate 300, thereby facilitating better intermittent heating of the heating plate 300.

[0082] Optionally, the fourth preset temperature is 80°C.

[0083] Optionally, before the controller 610 controls the heating plate 300 to heat to the fourth preset temperature, the controller 610 further includes: determining whether the refrigerator 600 is in a refrigeration mode, and if the refrigerator 600 is in a refrigeration mode, controlling the heating plate 300 to heat to the fourth preset temperature. In this way, after the refrigerator 600 is in a refrigeration mode, the heating plate 300 is controlled to heat, thereby avoiding a conflict between the cooling operation of the heat exchanger 100 and the defrosting operation of the heating plate 300.
