Description

[0001] DISPLAY MODULE

[0002] TECHNICAL FIELD

[0003] The present disclosure relates to heat transfer modules. Moreover, the present disclosure relates to electronic displays. Furthermore, the present disclosure relates to electronic billboards.

[0004] BACKGROUND

[0005] Outdoor display screens have become increasingly popular in recent years due to their ability to attract attention and engage audiences. One of the most common uses of outdoor display screens is for advertising purposes. The outdoor display screens can be used to display dynamic and eye-catching content, such as videos, animations, and images, that can quickly grab the attention of people passing thereby. As a result, businesses and organizations can use the outdoor display screens to promote their products, services, or events to a large audience in a highly effective and engaging way. Typically, the outdoor display screens are located in high-traffic areas, such as shopping malls, airports, and busy city centres. Moreover, the outdoor display screens can also be used to provide information to the public, such as weather updates, news headlines, or event schedules. They can also be used for entertainment purposes, such as displaying live sports events or concerts.

[0006] However, conventional outdoor display screens are vulnerable to weather conditions. The outdoor display screens are often exposed to harsh weather conditions such as rain, wind, snow, and extreme temperatures, which can damage or destroy the screens and other electronic components. This can result in costly repairs or replacements, and downtime. Typically, LED panels arranged in the outdoor display screen used in outdoor environments are extremely susceptible to high temperatures. Especially the display screens that are arranged in the direct sunlight. In direct sunlight, the surface temperature of an outdoor LED display screen can rise to more than 100°C, and internally, below the surface of the display screen, temperature can rise even higher. Overheating can cause failure or malfunction of the screen or components.

[0007] Current solutions involve the use of outside air (such as natural air) to cool the LED panels. The use of outside air requires filters to avoid the ingress of dust and dirt. However, the filters have the disadvantage as they require frequently replacement. Moreover, to avoid the ingress of dust and dirt and use of filters, the compressors are used to provide the clean air. However, the use of compressor increases the cost of operation of the outdoor display screens and requires regular maintenance.

[0008] Therefore, in light of the foregoing discussion, there exists a need to overcome the aforementioned drawbacks.

[0009] SUMMARY

[0010] The aim of the present disclosure is to provide a heat transfer module, an electronic display, and an electronic billboard to effectively transfer heat from electronic displays. The aim of the present disclosure is achieved by a heat transfer module, an electronic display and an electronic billboard as defined in the appended independent claims to which reference is made to.

Furthermore, the primary cooling channels being airtight in respect to the secondary cooling channels beneficially ensures that a contaminated air from an external atmosphere does not enter inside the aforementioned electronic billboard.

[0031] Throughout the present disclosure, the term "heat transfer module" refers to a hardware component that is designed to facilitate transfer of heat, i.e., transfer of thermal energy, between in a device or apparatus in which the heat transfer module is arranged to operate. Notably, the heat transfer module has a modular design that enables the heat transfer module to be easily inserted or removed from another device or apparatus.

Notably, the specific length of the first rectangular plate is equal to the first length (i.e., a specific measurement value), where two opposite edges of the first rectangular plate that are present at respective end points of the first length are the first edge and the second edge. Optionally, the first rectangular plate is made from heat-conductive materials. Optionally, the first rectangular plate is made from at least one of: aluminium, copper, silver, steel, brass.

[0033] Optionally, at least one rectangular plate is an active display element.

In an embodiment, the heat transfer module comprises only a single rectangular plate which is the first rectangular plate. In another embodiment, the heat transfer module comprises more than one rectangular plates, where the more than one rectangular plates comprises the first rectangular plate. Throughout the present disclosure, the term "active display element" refers to a component that illuminates to form desired patterns, numbers, letters, or images in order to render any sort of information on a display screen. Notably, heat is generated in the at least one rectangular plate as the at least one rectangular plate is the active display element. Advantageously, the heat generated in the at least one rectangular plate is effectively transferred to the external atmosphere using the heat exchanger element as the at least one rectangular plate is in the thermal contact with the heat exchanger element. The technical effect is that the heat transfer module is suitable to be used in various display devices such as Liquid Crystal Displays (LCDs), Light Emitting Diodes (LEDs), and the like.

[0034] Optionally, the heat transfer module further comprises a second rectangular plate having a third surface and a fourth surface opposite to the third surface and a third edge opposite to a fourth edge wherein distance between the third edge and the fourth edge is the first length. Herein, the second rectangular plate refers to another rectangular shaped plate similar to the first rectangular plate, where the second rectangular plate have the same properties and operation as the first rectangular plate. Subsequently, similar to the first rectangular plate which have the first surface and the second surface, the second rectangular plate also have the third surface and the fourth surface opposite to the third surface. Notably, the third surface and the fourth surface are respectively, present at opposite faces of the second rectangular plate. Similarly, as the first rectangular plate, the second rectangular comprises the third edge and the fourth edge which is opposite to the third edge. Moreover, the specific length of the second rectangular plate is equal to the first length, where two opposite edges of the second rectangular plate that are present at respective end points of the first length are the third edge and the fourth edge. The technical effect is that the heat transfer module is able to have two active display elements in the form of the first rectangular plate and the second rectangular plate, respectively. The other technical effect is that when the heat transfer modules are connected to each other by connecting the first rectangular plate and the second rectangular plate of the heat transfer modules to each other respectively, then no sealing or a tightening material is required to connect primary air channels (as described below) and the secondary cooling channels (as described below) of the heat transfer modules to each other respectively, at the same time keeping air flows in the primary cooling channels and secondary cooling channels separated for a more efficient cooling effect.

[0035] Moreover, the heat transfer module comprises the heat exchanger element arranged in the thermal contact with the second surface. Throughout the present disclosure, the term "heat exchanger element" refers to an element that allows an exchange of heat with the cool air. Notably, the heat exchanger element receives the heat that is absorbed by the heat transfer module from the first rectangular plate, as the heat exchanger element is in thermal connection with the second surface of the first rectangular plate. It will be appreciated that the second surface of the first rectangular plate and the heat exchanger element are made from heat-conductive materials which facilitate the thermal connection between the second surface and the heat exchanger element. Optionally, the heat exchanger element is made from at least one of: aluminium, copper, silver, steel, brass.

[0036] The heat exchanger element comprises the set of column-like bodies arranged lengthwise adjacent to each other and the length of each of the column-like body is the first length. Throughout the present disclosure, the term "column-like body" refers to a vertically elongated bodies that resemble a column, where the column-like body is hollow from inside. Optionally, a circumference of each column-like body is in shape of: a cylinder, a cuboid, and the like. Notably, the each column-like body from amongst the set of column-like bodies is of a specific length which is equal to the first length (i.e., the length of the first rectangular plate). It will be appreciated that each column-like body is arranged in the heat exchanger element in form of a row along a horizontal axis, adjacent to another column-like body from amongst the set of column-like bodies. In an embodiment, the heat exchanger element comprises multiple rows of column-like bodies that are arranged lengthwise adjacent to each other. Notably, the adjacent arrangement of the set of column of like bodies is such that the first length of a given column-like body is aligned with the first length of the another column-like body that is arranged adjacent to the given column-like body.

[0037] Optionally, the first rectangular plate, the second rectangular plate and the heat exchanger element form a stack in which the first edge is aligned with the third edge and the second edge is aligned with the fourth edge. Throughout the present disclosure, the term "stack" refers to a type of arrangement in which objects are placed next to each other in an organized manner. Notably, the first rectangular plate, the heat exchanger element, and the second rectangular plate are arranged in the stack such that the heat exchanger element is placed between the first rectangular plate and the second rectangular plate. Moreover, the first rectangular plate and the second rectangular plate are placed at the respective ends of the heat exchanger element such that the first edge is aligned with the third edge, and the second edge is aligned with the fourth edge. In other words, the first edge and the third edge are placed at a same level with respect to each other. Similarly, the second edge and the fourth edge are placed at the same level with respect to each other. Optionally, the third surface of the second rectangular plate is thermally connected to the heat exchanger element. The technical effect is that the heat exchanger element is able to absorb heat from both the first rectangular plate and the second rectangular plate. The other technical effect is that when the heat transfer modules are connected to each other by connecting the first rectangular plate and the second rectangular plate of the heat transfer modules to each other respectively, then no sealing or a tightening material is required to connect primary air channels (as described below) and secondary cooling channels (as described below) of the heat transfer modules to each other respectively, at the same time keeping air flows in the primary cooling channels and secondary cooling channels separated for a more efficient cooling effect.

[0038] Optionally, the first rectangular plate is of a first width and diameter of column-like bodies is the first width divided by number of column-like bodies in the heat exchanger element. Herein, the term "first width" refers to a specific measurement value. Notably, the specific width for the first rectangular plate is equal to the first width. In this regard, a total width of the adjacent arrangement of the column-like bodies in the heat exchanger element is equal to the first width of the first rectangular plate. Moreover, each column-like body in the adjacent arrangement of the set of column-like bodies is of an equal diameter. Subsequently, the diameter for each column-like body is determined by dividing the first width with the number of column-like bodies in the heat exchanger element. The technical effect is that the second surface of the first rectangular plate is in the thermal contact with the column-like bodies in the heat exchanger element throughout the first width of the first rectangular plate.

[0039] Optionally, the second rectangular plate is of the first width. In this regard, the specific width for the second rectangular plate is equal to the first width. The technical effect of the second rectangular plate to be of the first width is that the second rectangular plate is advantageously, designed to be symmetrical to the first rectangular plate.

[0040] Moreover, the longitudinal ends of the adjacent column-like bodies are in the offset relation to each other in the direction with respect to the first length and the column-like bodies are in the thermal connection lengthwise with the at least one neighbouring adjacent column-like body. Throughout the present disclosure, the term "longitudinal end" refers to an end of the given column-like body which is closer to the second edge of the first rectangular plate in comparison to another end of the given column-like body. Notably, each column-like body from amongst the set of column-like bodies have two longitudinal ends which are a first longitudinal end and a second longitudinal end. Throughout the present disclosure, the term "offset" refers to a deviation in alignment of the longitudinal ends of the given column-like body with the longitudinal ends of the another column-like body adjacent to the given column-like body. Optionally, the offset between the longitudinal ends of the adjacent column-like bodies is of a predefined distance DI. Optionally, the distance DI is in a range of 2 centimetres (cm) to 10 cm. It will be appreciated that the offset between the adjacent column-like bodies is in the direction which is parallel to an axis in which the first length is present. Notably, the thermal connection of the given column-like body lengthwise with the at least one neighbouring adjacent body enables transfer of heat throughout the first length of the given column-like body with the at least one neighbouring adjacent column-like body. It will be appreciated that the set of column-like bodies are made of heat-conductive material to enable thermal connection between the set of column-like bodies. Optionally, the column-like bodies are made from at least one of: aluminium, copper, silver, steel, brass.

[0041] Optionally, the offset between a first pair of column-like bodies is different from the offset between a second pair of column-like bodies. In this regard, there exists the offset between every possible pair of adjacent column-like bodies from amongst the set of column-like bodies. Herein, the term "first pair of column-like bodies" refers to a pair of adjacent column-like bodies from amongst the set of column-like bodies. Herein, the term "second pair of column-like bodies" refers to another pair of adjacent column-like bodies, where at least one column-like body from amongst the second pair of column-like bodies is different from the first pair of column-like bodies. The technical effect of having the offset between the first pair of column-like bodies different from the offset between the second pair of column-like bodies is that there is no need to have any sealing or tightening material between the first pair of columnlike bodies and separately between the second pair of column-like bodies. The other technical effect is that even in a case where there is an air leakage in the first pair of column-like bodies then air flow in the first pair of column-like bodies is not mixed with air flow in the second pair of column-like bodies.

[0042] Optionally, a first group from amongst the set of column-like bodies are part of primary cooling channels and a second group from amongst the set of column-like bodies are part of secondary cooling channels and wherein an adjacent column-like body of the each column-like body of the first group is of the second group. Throughout the present disclosure, the term "first group from amongst the set of column-like bodies" refers to a certain number of column-like bodies from amongst the set of column-like bodies selected to be part of the first group from amongst the set of column-like bodies. Throughout the present disclosure, the term "second group from amongst the set of column-like bodies" refers to those remaining column-like bodies from amongst the set of columnlike bodies which are not part of the first group. Notably, the selection of the first group and the second group is done such that the column-like body which is placed consecutively next (i.e., the adjacent column like body) to the each column-like body of the first group is a respective column-like body of the second group. Throughout the present disclosure, the term "primary cooling channels" refers to channels that provide a passage for flow of air from the external atmosphere into the primary cooling channels and from the primary cooling channels back into the external atmosphere. Throughout the present disclosure, the term "secondary cooling channel" refers to the channels that provide a passage for flow of hot air that is received from the first rectangular plate into the secondary cooling channels. It will be appreciated that column-like bodies of the first group and the second group are open at both the longitudinal ends and are hollow from the inside, which makes column-like bodies of the first group and the second group suitable to be part of the primary cooling channels and the secondary cooling channels, respectively. Notably, the use of the column-like bodies of the first group as the primary cooling channels enables cool air from the external atmosphere to flow into the column-like bodies of the first group (i.e., essentially, inside the heat exchanger element of the heat transfer module). Herein, the heat is exchanged between the hot air that flows in the column-like bodies of the first group with the cool air that flows in the column-like bodies of the second group via the thermal connection between the column-like bodies of the first group and the column-like bodies of the second group. Subsequently, the exchanged heat is then removed from column-like bodies of the first group into the external atmosphere. The technical effect is that the heat transfer module is able to effectively dissipate the heat into the external atmosphere by the column-like bodies of the first group being the part of the primary cooling channels and the column-like bodies of the second group being the part of the secondary cooling channels.

[0043] Optionally, the set of column-like bodies comprises: a first column-like body, a second column-like body, a third column-like body and a fourth column-like body. In this regard, the set of column-like bodies comprises of at four column-like bodies which are the first column-like body, the second column-like body, the third column-like body, and the fourth column-like body. Although, in some embodiments, the set of columnlike bodies comprises more than four column-like bodies in which the first column-like body, the second column-like body, the third column-like body, and the fourth column-like body are part of the set of column-like bodies. Notably, the set of the column-like bodies in the heat-exchanger element is arranged such that the second column-like body is adjacent to the first column-like body, the third column-like body is adjacent to the second column-like body, the fourth column-like body is adjacent to the third column-like body. The technical effect is that the longitudinal ends of the first column-like body are in the offset relation to the longitudinal ends of the second column-like body. Similarly, the longitudinal ends of the second column-like body are in the offset relation to the longitudinal ends of the third column-like body. Similarly, the longitudinal ends of the third column-like body are in the offset relation to the longitudinal ends of the fourth column-like body.

[0044] Optionally, a set of heat transfer modules are interconnectable, by connecting a first heat transfer module of the set of heat transfer modules with a second heat transfer module of the set of heat transfer modules, in a way that the first edge of the first heat transfer module is in contact with a second edge of the second heat transfer module, and the third edge of the first heat transfer module is in contact with the fourth edge of the second heat transfer module. In this regard, the modular design of a given heat transfer module enables to interconnect the set of heat transfer modules (i.e., more than one heat transfer modules). Notably, the interconnection of the first heat transfer module with the second heat transfer module is such that the first edge of the first heat transfer module is joined with the second edge of the second heat transfer module, and thus, the first surface of the first heat transfer module is arranged adjacent to a first surface of the second heat transfer module and the second surface of the first heat transfer module is arranged adjacent to a second surface of the second heat transfer module. Similarly, the third edge of the first heat transfer module is joined with the fourth edge of the second heat transfer module, and thus, the third surface of the first heat transfer module is arranged adjacent to a third surface of the second heat transfer module and the fourth surface of the first heat transfer module is arranged adjacent to a fourth surface of the second heat transfer module. It will be appreciated that the interconnection between any two heat transfer modules from amongst the set of heat transfer modules is identical to the interconnection of the first heat transfer module with the second heat transfer module. The technical effect of the interconnection between the set of heat transfer modules is that multiple heat transfer modules are connected to increase a scale of operation of the heat transfer module.

It will be appreciated that the interconnection between any two heat transfer modules from amongst the set of heat transfer modules is identical to the interconnection of the first heat transfer module with the second heat transfer module.

[0048] Notably, the set of the heat transfer modules arranged with the electronic display receive the heat from the electronic display. Subsequently, the heat is then transferred to the secondary cooling channels in a heat exchanger element in a given heat transfer module from a first rectangular plate of the given heat transfer module via a thermal connection between the first rectangular plate and the heat exchanger element in the given heat exchanger element. Subsequently, the heat is then transferred from the secondary cooling channels to the primary cooling channels in the given heat transfer module.

[0049] Optionally, the primary cooling channels provide air flow through the electronic display to transfer heat outside of the display and the secondary cooling channels are arranged to circulate air within the electronic display. In this regard, the air flow through the electronic display in the primary cooling channels enables to provide a passage for cool air from an external atmosphere to enter the primary channels for exchanging heat with the secondary cooling channels, and provide the passage for the exchanged heat to flow out via the primary channels and as a result, to flow out from the electronic display. Similarly, the circulation of air within the electronic display in the secondary cooling channels enables to transfer the generated heat in the electronic display to the secondary cooling channels.
