在電力傳輸的 “隱秘戰(zhàn)場” 中，電纜橋架不僅是線纜的 “守護者”，更是散熱的 “關鍵衛(wèi)士”。電纜運行時會產生熱量，若無法及時散發(fā)，就像給設備裹上了 “悶汗的棉被”，不僅影響性能，還可能埋下隱患。不同類型的電纜橋架在散熱能力上各有千秋，一場激烈的 “散熱” 爭奪戰(zhàn)正在上演，究竟誰能脫穎而出，成為熱量的克星呢？

　　In the "hidden battlefield" of power transmission, cable trays are not only the "guardians" of cables, but also the "key guardians" of heat dissipation. During cable operation, heat is generated. If it cannot be dissipated in a timely manner, it is like wrapping the equipment in a "sweaty blanket", which not only affects performance but may also pose safety hazards. Different types of cable trays have their own advantages in terms of heat dissipation. A fierce battle for the "heat dissipation champion" is unfolding. Who can stand out and become the nemesis of heat?

　　網格式橋架堪稱散熱界的 “先鋒大將”。它獨特的網狀結構就像一張開放的 “透氣網”，擁有極大的通風面積。電纜在網格式橋架中鋪設時，幾乎完全暴露在空氣中，四面都能與空氣充分接觸，這種的接觸方式，使得熱量能夠迅速通過對流和輻射的方式散發(fā)到周圍環(huán)境中。就好比給電纜穿上了一件 “鏤空透氣衫”，空氣可以自由穿梭，帶走多余熱量。而且，網格式橋架的結構不會形成封閉空間阻礙空氣流動，即使在電纜密集鋪設的情況下，也能保證良好的散熱效果，特別適合對散熱要求極高的機房、數據中心等場所，讓大量發(fā)熱的電纜始終保持 “冷靜” 狀態(tài)。

　　The grid format cable tray can be regarded as a "pioneer general" in the field of heat dissipation. Its unique mesh structure is like an open "breathable mesh" with a large ventilation area. When cables are laid in grid format cable trays, they are almost completely exposed to the air and can fully contact the air on all sides. This all-round contact method allows heat to be quickly dissipated into the surrounding environment through convection and radiation. It's like putting a "hollow breathable shirt" on the cable, where air can freely shuttle and take away excess heat. Moreover, the structure of the grid format cable tray does not form a closed space that hinders air flow. Even in densely laid cables, it can ensure good heat dissipation effect, especially suitable for places with extremely high heat dissipation requirements such as computer rooms and data centers, keeping a large number of heating cables in a "calm" state at all times.

　　梯級式橋架是散熱領域的 “實力選手”。它的形狀如同梯子，側板上設有開放式的梯級，這種設計為空氣流動提供了寬敞的通道。電纜鋪設在梯級上，底部懸空，空氣能夠從下方自由流通，形成上下貫通的散熱通道。同時，梯級式橋架的梯級間距較大，電纜之間也有足夠的空間，進一步減少了熱量積聚的可能性。當電纜運行產生熱量時，熱空氣會沿著梯級間的空隙上升，冷空氣不斷補充，形成自然的熱對流循環(huán)，如同給電纜搭建了一座 “通風走廊”，有效加快熱量散發(fā)速度。在一些工業(yè)廠房等場所，由于電纜數量多、發(fā)熱量大，梯級式橋架憑借出色的散熱性能和較強的承載能力，成為保障電纜穩(wěn)定運行的可靠選擇。

　　Cascade bridge is a "strong player" in the field of heat dissipation. Its shape is like a ladder, with open steps on the side panels, providing a spacious passage for air flow. The cable is laid on the steps, with the bottom suspended, allowing air to freely circulate from below, forming a heat dissipation channel that runs up and down. At the same time, the spacing between the steps of the stepped bridge is relatively large, and there is sufficient space between the cables, further reducing the possibility of heat accumulation. When the cable generates heat during operation, hot air rises along the gaps between the steps, while cold air continuously replenishes, forming a natural heat convection cycle, like building a "ventilation corridor" for the cable, effectively accelerating the heat dissipation rate. In some industrial plants and other places, due to the large number of cables and high heat generation, stepped cable trays have become a reliable choice for ensuring stable cable operation due to their excellent heat dissipation performance and strong load-bearing capacity.

　　托盤式橋架家族中的 “打孔派”，也在散熱戰(zhàn)場上占據一席之地。普通的托盤式橋架是一個封閉的槽形結構，散熱能力相對較弱，但經過改良的打孔托盤式橋架則大不相同。它在托盤底部和側邊均勻分布著許多小孔，這些小孔就像一個個 “散熱窗口”，打破了封閉空間的局限。電纜產生的熱量可以通過這些小孔與外界空氣進行交換，實現(xiàn)熱量的散發(fā)。雖然打孔托盤式橋架的散熱效果不如網格式和梯級式橋架那樣直接和，但相比普通托盤式橋架，其散熱能力有了顯著提升。在對散熱有一定要求，同時又需要對電纜進行較好防護的場所，如建筑物內部的電氣布線，打孔托盤式橋架就能兼顧散熱與防護，發(fā)揮重要作用。

　　The "punching faction" in the tray style bridge family also occupies a place in the battlefield of heat dissipation. The ordinary tray type bridge is a closed groove structure with relatively weak heat dissipation ability, but the improved perforated tray type bridge is quite different. It has many small holes evenly distributed at the bottom and sides of the tray, which are like "heat dissipation windows" that break the limitations of enclosed spaces. The heat generated by the cable can be exchanged with the outside air through these small holes, achieving heat dissipation. Although the heat dissipation effect of perforated tray type bridge is not as direct and efficient as that of grid format and stepped bridge, its heat dissipation capacity has been significantly improved compared to ordinary tray type bridge. In places where there are certain requirements for heat dissipation and good protection for cables, such as electrical wiring inside buildings, perforated tray type cable trays can balance heat dissipation and protection, playing an important role.

　　在電纜橋架的 “散熱” 爭奪戰(zhàn)中，網格式橋架憑借開放結構的天然優(yōu)勢、梯級式橋架依靠獨特的通風設計、打孔托盤式橋架借助改良的散熱孔，各自展現(xiàn)出強大的散熱實力。在實際應用中，根據不同場所對散熱、防護、美觀等方面的需求，選擇合適的電纜橋架類型，才能讓電纜在傳輸電力時始終保持 “清爽”，為電力系統(tǒng)的穩(wěn)定運行保駕護航。

　　In the battle for the "heat dissipation champion" of cable trays, grid trays showcase their strong heat dissipation capabilities with the natural advantage of open structure, stepped trays with unique ventilation design, and perforated tray trays with improved heat dissipation holes. In practical applications, selecting the appropriate cable tray type based on the needs of different places for heat dissipation, protection, aesthetics, etc. is necessary to ensure that the cables remain "clean" during power transmission and to safeguard the stable operation of the power system.
