機(jī)柜內(nèi)部散熱不良會(huì)導(dǎo)致機(jī)柜內(nèi)的設(shè)備或精密電子元件燒毀，影響正常工作，因此機(jī)箱和機(jī)柜的散熱問題一直是人們很頭疼的問題，下面來講講怎么有效的處理這個(gè)問題。

Poor heat dissipation inside the cabinet will lead to the burning of equipment or precision electronic components in the cabinet and affect the normal work. Therefore, the heat dissipation of the chassis and cabinet has always been a headache for people. Let's talk about how to deal with this problem effectively.

目前大部分機(jī)柜的降溫都是通過降低機(jī)房溫度來控制機(jī)柜內(nèi)各設(shè)備的溫度。隨著機(jī)柜擴(kuò)展空間的不斷擴(kuò)大，設(shè)備的密度越來越緊湊，對(duì)機(jī)柜內(nèi)的散熱產(chǎn)生不利影響。因此，有效解決高密度設(shè)備機(jī)柜的散熱問題勢(shì)在必行。

At present, the cooling of most cabinets is to control the temperature of each equipment in the cabinet by reducing the temperature of the machine room. With the continuous expansion of cabinet expansion space, the density of equipment becomes more and more compact, which has an adverse impact on the heat dissipation in the cabinet. Therefore, it is imperative to effectively solve the heat dissipation problem of high-density equipment cabinet.

隨著機(jī)箱和機(jī)柜技術(shù)的不斷提高，鈑金機(jī)箱和機(jī)柜的做工也越來越精細(xì)，其結(jié)構(gòu)設(shè)計(jì)也越來越精致。新型機(jī)箱機(jī)柜采用開槽箱邊結(jié)構(gòu)。門上貼有聚氨酯泡沫密封防水膠帶，可緊密貼在開槽箱的邊緣。活動(dòng)安裝板的內(nèi)部設(shè)計(jì)，使設(shè)備的安裝更加方便快捷。并且頂部有散熱孔，更好的增強(qiáng)散熱效果。

With the continuous improvement of chassis and cabinet technology, the workmanship of sheet metal chassis and cabinet is becoming more and more fine, and its structural design is becoming more and more exquisite. The new cabinet adopts slotted box edge structure. The door is pasted with polyurethane foam sealing waterproof tape, which can be closely pasted on the edge of the slotted box. The internal design of the movable mounting plate makes the installation of the equipment more convenient and fast. And there are heat dissipation holes on the top to better enhance the heat dissipation effect.

機(jī)箱機(jī)柜還采用新技術(shù)采用機(jī)箱機(jī)柜的熱設(shè)計(jì)原理，從而更好地提高機(jī)箱等設(shè)備內(nèi)部電子元件的傳熱能力；同時(shí)提高了底盤對(duì)外界的傳熱能力；很大限度地減少傳熱路徑，從而形成低熱阻的熱流路，從而更好地保證設(shè)備在一定溫度范圍內(nèi)正常運(yùn)行。

The cabinet also adopts new technology and adopts the thermal design principle of the cabinet, so as to better improve the heat transfer capacity of electronic components inside the cabinet and other equipment; At the same time, the heat transfer ability of the chassis to the outside world is improved; Greatly reduce the heat transfer path, so as to form a heat flow path with low thermal resistance, so as to better ensure the normal operation of the equipment within a certain temperature range.

我們?nèi)绾翁幚頇C(jī)箱機(jī)柜的熱設(shè)計(jì)？或者怎樣才能更好的提高機(jī)箱和機(jī)柜的散熱效率？鈑金機(jī)箱的散熱設(shè)計(jì)其實(shí)就是為了增加機(jī)箱內(nèi)外蒙皮的黑度，并通過開通風(fēng)孔來達(dá)到散熱的功能，從而降低溫度。一般來說，高黑度在機(jī)柜內(nèi)外表面的效果要好于低黑度，而且機(jī)箱兩側(cè)都有高黑度散熱。

How do we deal with the thermal design of the chassis cabinet? Or how can we better improve the heat dissipation efficiency of chassis and cabinet? In fact, the heat dissipation design of sheet metal chassis is to increase the blackness of the inner and outer skin of the chassis, and achieve the function of heat dissipation by opening air holes, so as to reduce the temperature. Generally speaking, the effect of high blackness on the inner and outer surfaces of the cabinet is better than that of low blackness, and there is high blackness heat dissipation on both sides of the chassis.

機(jī)箱機(jī)柜的通風(fēng)孔是用來散熱的，那么它是用什么原理來散熱的呢？機(jī)柜底盤上的通風(fēng)口利用冷空氣對(duì)流換熱的原理進(jìn)行散熱。但是，機(jī)箱機(jī)柜上的通風(fēng)孔的開設(shè)應(yīng)遵循一定的原則。

The ventilation hole of the cabinet is used to dissipate heat, so what principle does it use to dissipate heat? The vent on the cabinet chassis uses the principle of cold air convection heat transfer to dissipate heat. The ventilation hole of the cabinet shall be set in a certain principle.

通風(fēng)孔開孔的基本原則是通風(fēng)孔的開孔應(yīng)有利于氣流形成有效的對(duì)流通道，進(jìn)風(fēng)孔應(yīng)盡可能與加熱氣體對(duì)齊，進(jìn)氣孔應(yīng)與出氣孔保持一定距離。從而避免了氣流的短路現(xiàn)象。通風(fēng)孔應(yīng)開在相應(yīng)溫差較大的位置，進(jìn)風(fēng)孔也要注意防塵和防電磁泄漏。

The basic principle of ventilation hole opening is that the opening of ventilation hole shall be conducive to the formation of effective convection channel for air flow, the air inlet hole shall be aligned with the heated gas as far as possible, and the air inlet hole shall be kept at a certain distance from the air outlet. Thus, the short circuit phenomenon of air flow is avoided. The ventilation hole shall be opened at the position with large temperature difference, and the air inlet shall also pay attention to dust prevention and electromagnetic leakage.
