Description

Technical Field

[0001] The present application relates to the field of ice storage technology, and in particular to an ice storage device and a chiller. Background Art

[0002] Ice storage air conditioning technology is an energy-saving technology that uses cheap valley electricity to make ice and store energy, and releases cold energy for air conditioning during peak electricity hours. Ice storage air conditioners can be roughly divided into two categories according to the ice making method: static ice making and dynamic ice making. Among them, there are two ice melting methods for static ice making, one is external ice melting method and the other is internal ice melting method. Small ice storage air conditioning units generally use direct fluorine refrigeration ice storage and internal ice melting method. The cold energy released by ice melting is used to increase the supercooling degree of the refrigeration cycle to achieve the purpose of energy saving, rather than actually using the cold capacity of ice melting for direct cooling.

[0003] In the related technologies, there are many technologies for realizing the ice-making function. Liquid film flow has a better heat exchange effect. Therefore, how to form a better liquid film is a technical problem that needs to be solved urgently. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide an ice storage device and a chiller that can form a better liquid film, thereby achieving a better heat exchange effect.

[0005] In a first aspect, an embodiment of the present application provides an ice storage device, comprising: a heat exchanger, comprising a plurality of plates, wherein the plurality of plates are spaced apart along a first direction; a water spreading assembly, comprising a water spreading tray, wherein the water spreading tray is disposed on the heat exchanger, and wherein the water spreading tray has a plurality of rows of water spreading groups distributed along the first direction, wherein each row of the water spreading groups is provided with a plurality of water spreading holes, and a center line of at least one of the plurality of rows of the water spreading groups is directly opposite to one of the plates.

[0006] In the above implementation process, a plurality of plates are configured, and a water-spreading tray is located on one side of the heat exchanger, wherein the water-spreading tray has a plurality of rows of water-spreading groups, and each plate corresponds to at least one center line of a water-spreading group, so that when the water-spreading group spreads water, a liquid film can be well formed on the surface of the plate, thereby achieving a better heat exchange effect.

[0007] In some embodiments, the heat exchanger further comprises a support tube, wherein the support tube is connected to the plate, and the water spreading tray is disposed on a side of the support tube facing away from the plate.

[0008] In the above implementation process, the support tube connects the plate. When the water-spreading tray is placed on the support tube, the support tube can not only support the water-spreading tray, but also, after the water-spreading tray spreads water, the water source can flow along the outer edge of the support tube to the plate to form a better liquid film on the plate, thereby achieving a better heat exchange effect.

[0009] In some embodiments, the diameter of the support tube is not less than the thickness of the plate, and at least one row of the water-spreading groups corresponds to the side of the support tube away from the plate. By setting the diameter of the support tube to be not less than the thickness of the plate, the water source spread on the support tube can flow along the outer edge of the support tube until it flows to the plate, thereby forming a better liquid film, achieving a better heat exchange effect, and higher ice-making efficiency.

[0010] In some embodiments, the diameter of the water-spreading hole is not greater than the diameter of the support tube. When the water-spreading group is spreading water, it can completely pass through the outer edge of the support tube and flow to the plate to form a liquid film, thereby achieving a better heat exchange effect and higher ice-making efficiency.

[0011] In some embodiments, the plate is provided with bulges and pressure points so that a refrigerant flow channel is formed inside the plate.

[0012] In some embodiments, the water spreading assembly further includes a water spreading pipe, which is disposed on a side of the water spreading tray away from the plate, for spreading water to the water spreading tray.

[0013] In some embodiments, the ice storage device further includes a refrigerant system, which is connected to the heat exchanger to provide refrigerant to the heat exchanger. The refrigerant is provided to the heat exchanger through the refrigerant system, and the refrigerant flows inside the plate, and a liquid film area can be formed outside the plate, and the heat of the liquid film is absorbed by the evaporation of the internal refrigerant, and finally ice cubes are formed.

[0014] In some embodiments, the ice storage device further includes a circulation component, and the circulation component is connected to the water spreading component. The circulation component continuously provides water to the water spreading component, and with the cooperation of the water spreading plate and the support pipe, it is not only conducive to the formation of a liquid film on the plate and improves the ice making efficiency, but also can recycle the water source and reduce resource waste.

[0015] In a second aspect, the present application also provides a chiller, comprising an ice storage device as described in any of the above items.

[0016] Since the chiller provided in the second aspect includes an ice storage device, the chiller has all the technical effects of the ice storage device, which will not be described in detail here.

[0031] Example

[0032] At present, energy issues are a hot topic of global concern, and various research topics on energy storage are increasing. With the continuous efforts of predecessors, ice storage, heat storage, electricity storage and other technologies have been put into practical application to a certain extent. The present application provides an ice storage device that can achieve the purpose of ice storage; among them, regarding the technology of ice storage, the heat transfer problem related to liquid film flow has a history of several decades, and its advantages of heat exchange are not elaborated here.

[0033] like Figure 1-Figure 3As shown, in the first aspect, an embodiment of the present application provides an ice storage device, comprising: a heat exchanger 100, comprising a plurality of plates 101, wherein the plurality of plates 101 are spaced apart along a first direction; a water spreading assembly 200, comprising a water spreading tray 201, wherein the water spreading tray 201 is disposed on the heat exchanger 100, and the water spreading tray 201 has a plurality of rows of water spreading groups distributed along the first direction, wherein each row of the water spreading groups is provided with a plurality of water spreading holes 2011, and a center line of at least one of the plurality of rows of the water spreading groups is directly opposite to one of the plates 101.

[0034] Exemplarily, the ice storage device is applied to a chiller, and the heat exchanger 100 includes but is not limited to a plate and tube heat exchanger. When the chiller is switched to an ice-making and cold-storage mode at night, the heat exchanger 100 can be used as an evaporator. When the chiller needs to perform de-icing, the heat exchanger 100 can be used as a condenser.

[0035] It should be noted that each of the plate pieces 101 corresponds to at least one row of the water-spreading groups, and the center line of the water-spreading groups is opposite to the plate piece 101, that is, each row of the water-spreading groups includes a plurality of the water-spreading holes 2011, and the water-spreading holes 2011 include but are not limited to a circle, and the line connecting the centers of the circles of the plurality of the water-spreading holes 2011 is the center line, and the center line is opposite to the plate piece 101, and the distribution direction of the center line is perpendicular to the first direction, and the first direction includes but is not limited to the left and right direction, and the distribution direction of the center line includes but is not limited to the front and back direction; wherein the apertures of the water-spreading holes 2011 can be set to be consistent, and the spacing between two adjacent water-spreading holes 2011, the number of water-spreading holes 2011 in each row of the water-spreading groups, and the number of rows of the water-spreading groups are not specifically limited and can be set according to actual conditions.

[0036] In the above implementation process, the plate 101 is configured with several water-spreading trays 201 located on one side of the heat exchanger 100, wherein the water-spreading tray 201 has several rows of water-spreading groups, and each plate 101 corresponds to at least one center line of a water-spreading group, so that when the water-spreading group spreads water, a liquid film can be well formed on the surface of the plate 101, thereby achieving a better heat exchange effect.

[0037] like Figure 1-Figure 3 As shown, the heat exchanger 100 also includes a support tube 102, the support tube 102 is connected to the plate 101, and the water-spraying plate 201 is arranged on the side of the support tube 102 away from the plate 101, wherein the upper and lower ends of one of the plates 101 are connected to the support tube 102, the water-spraying plate 201 is arranged on the upper end of the support tube 102 and supported by it, and the support tube 102 includes but is not limited to a hollow circular tube.

[0038] In the above-mentioned implementation process, the support tube 102 is connected to the plate 101. When the water-spreading tray 201 is placed on the support tube 102, the support tube 102 can not only support the water-spreading tray 201, but also after the water-spreading tray 201 spreads water, the water source can flow along the outer edge of the support tube 102 to the plate 101, so as to form a better liquid film on the plate 101, thereby achieving a better heat exchange effect.

[0039] like Figure 3 As shown, the diameter of the support tube 102 is not less than the thickness of the plate 101. In one embodiment of the present application, the diameter of the support tube 102 is greater than the thickness of the plate 101, and after the plate 101 is connected to the support tube 102, the plate 101 can be roughly located at the center of the support tube 102, so that both sides of the plate 101 can correspond to the semicircular support tube 102, which is conducive to forming a liquid film on the surface of the plate 101, and the side of the support tube 102 away from the plate 101 corresponds to at least one row of the water-spreading group. By setting the diameter of the support tube 102 to be not less than the thickness of the plate 101, the water source spread on the support tube 102 can flow along the outer edge of the support tube 102 until it flows to the plate 101, thereby forming a better liquid film, achieving a better heat exchange effect, and higher ice making efficiency.

[0040] Please refer to Figure 3 , the diameter of the water-spreading hole 2011 is not greater than the diameter of the support tube 102. In one embodiment of the present application, the diameter of the water-spreading hole 2011 is smaller than the diameter of the support tube 102, and the center of the water-spreading hole 2011 and the center of the support tube 102 are located on the same vertical line, so that the water source spread from the water-spreading hole 2011 can flow evenly to the outer edge of the support tube 102. When the water-spreading group is spreading water, it can completely pass through the outer edge of the support tube 102 and flow to the plate 101 to form a liquid film, thereby achieving a better heat exchange effect and higher ice-making efficiency.

[0041] In some embodiments, the plate 101 is configured with bulges and pressure points so that a refrigerant flow channel is formed inside the plate 101. The refrigerant flow channel can be used to accommodate refrigerant. The plate 101 can absorb the heat of the liquid film through the evaporation of the refrigerant in the refrigerant flow channel, and finally form ice cubes.

[0042] In some embodiments, the water-spreading assembly 200 further includes a water-spreading pipe 202, which is disposed on a side of the water-spreading tray 201 away from the plate 101, for spreading water to the water-spreading tray 201. In one embodiment, the water-spreading pipe 202 is a water pipe with a specific hole opening method and structure, and a hole diameter of the water-spreading pipe 202 is set to be larger than a water-spreading hole 2011 of the water-spreading tray 201, so that when the water-spreading pipe 202 and the water-spreading tray 201 work at the same time, a water level of a certain depth can be formed inside the water-spreading tray 201, thereby avoiding the occurrence of poor liquid film effect due to the flatness problem inside the water-spreading tray 201.

[0043] In some embodiments, the ice storage device further includes a refrigerant system, which is connected to the heat exchanger 100 to provide refrigerant to the heat exchanger 100. The refrigerant is provided to the heat exchanger 100 through the refrigerant system, and the refrigerant flows inside the plate 101, and a liquid film area can be formed outside the plate 101, and the heat of the liquid film is absorbed by the evaporation of the internal refrigerant, and finally ice cubes are formed.

[0044] In some embodiments, the ice storage device further includes a circulation component 300, the circulation component 300 includes a water pump and a water pipe, etc., and the circulation component 300 is connected to the water spreading component 200. The circulation component 300 continuously provides water to the water spreading component 200. With the cooperation of the water spreading tray 201 and the support pipe 102, it is not only conducive to the formation of a liquid film on the plate 101 and the improvement of ice making efficiency, but also the water source can be recycled to reduce resource waste.

[0045] like Figure 4 As shown, in a second aspect, the present application also provides a chiller, comprising the ice storage device as described above.

[0046] When the solenoid valve 400 (normally closed) is not energized, the chiller operates as an evaporative cooling unit, that is, a chiller that provides chilled water to users on a daily basis; when the chiller switches to the ice-making and cold-storage mode at night, the solenoid valve 400 (normally closed) is energized and the electronic expansion valve 500 is closed, the ice storage device acts as an evaporator to make ice cubes by a liquid film ice-making method, and the evaporative cooling condenser 600 still functions as a condenser; when the system determines that the ice cubes have formed to a certain extent, de-icing is required, at which time the solenoid valve 400 (normally closed) loses power and the four-way reversing valve 700 is energized, at which time the evaporative cooling condenser 600 functions as an evaporator, and the ice storage device functions as a condenser, and the high-temperature and high-pressure refrigerant flows through the heat exchanger 100 of the ice storage device, so that a fine gap is generated between the surface of the heat exchanger 100 and the ice cubes, and the ice cubes fall off through the operation of the water pump and the action of gravity.

[0047] Since the chiller provided in the second aspect includes an ice storage device, the chiller has all the technical effects of the ice storage device, which will not be described in detail here.

[0048] In all the embodiments of the present application, "big" and "small" are relative, "more" and "less" are relative, and "up" and "down" are relative. The expressions of such relative terms are not elaborated in the embodiments of the present application.

[0049] It should be understood that the "in this embodiment", "in the embodiment of the present application" or "as an optional implementation" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, "in this embodiment", "in the embodiment of the present application" or "as an optional implementation" appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner. Those skilled in the art should also be aware that the embodiments described in the specification are all optional embodiments, and the actions and modules involved are not necessarily required for the present application.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
