To sum up, the emergent heat radiation structure that this embodiment provided can carry out automatically regulated accuse temperature according to the inside capacity of applied equipment, and it is automatic when equipment function monitors the inside temperature of equipment, and the refrigeration module that is taken certainly breaks down unable operation to when the inside temperature of equipment rises or falls to the temperature value that the system set for, then emergent heat dissipation operation will be opened automatically to this structure, props up movable cover plate, opens emergent fan, dispels the heat to cabinet body inside. And this urgent heat radiation structure has still solved the problem that the structure of emergent fan appearing in the existing market is complicated, the installation is difficult, the leakproofness is low etc.

The emergent heat radiation structure that this embodiment provided can be applicable to in equipment such as the cabinet body or box, and its self possesses the wholeness, and the structure is few, and processing is simple, owing to be whole combination assembly design, can directly change the size production equipment back according to the target and transport and install or assemble again in the application place, has both alleviateed assembler's the work degree of difficulty, has also improved assembly efficiency.

Example two:

at present, refrigeration and heat dissipation of a modular data center are all provided by an air conditioner refrigeration module, if the refrigeration module breaks down and stops running, the temperature inside a cabinet can quickly rise, and certain potential safety hazards (such as overheating short circuit of equipment, equipment data loss, fire and the like) exist for equipment in the cabinet and even the whole machine room; if under the condition that the number of server equipment in the cabinet body is less, the load is less, the heat energy in the cabinet is not high and the air conditioner refrigeration module is always running, the temperature in the cabinet is too low, the air conditioner can be automatically started and stopped and an alarm is generated, and multiple cycles easily cause equipment faults and damage.

Although the emergency heat dissipation system in the current market can provide an emergency heat dissipation function, the operation of the refrigeration module cannot be guaranteed, the interior of the cabinet is in a sealed state, and the refrigeration effect in the cabinet is not high. Secondly, the emergency heat dissipation system in the current market cannot intelligently control and adjust emergency heat dissipation equipment according to the load condition. Therefore, the emergency heat dissipation structure can be applied to cabinet equipment or other box body structures, and can ensure the sealing property of the interior of the cabinet body when the refrigeration module operates normally, so as to play a role in dust prevention and water prevention; when the refrigeration module breaks down, still can independently monitor the internal portion temperature condition of cabinet to detect the internal portion temperature of cabinet and exceed the emergent heat dissipation function of automatic start when presetting the temperature value, in order to reach and dispel the heat to the internal portion equipment of cabinet, avoid the internal portion equipment of cabinet excessive loss or the trouble scheduling problem of failure under the too high condition of temperature. The following is a cabinet that possesses emergent heat dissipation function that this application provided, and it is the example that the emergent heat dissipation structure that this application disclosed was applied to cabinet body equipment also.

Specifically, referring to fig. 4 to 6, a second embodiment provides a cabinet with an emergency heat dissipation function, which includes a cabinet body 60, and further includes an emergency heat dissipation structure according to the first embodiment. The cabinet body 60 is provided with an installation opening 107 which is matched with the shell 10 and communicated with the inner space of the cabinet body 60, the shell 10 is fixedly arranged on the installation opening 107 and is arranged in a direction deviating from the inner direction of the cabinet body 60 by the first ventilation opening 100, and when the movable assembly is covered on the first ventilation opening 100, the cabinet body 60 is in a sealing state.

The problem of most do not dispose emergent heat radiation structure in the integration rack on the existing market, or the integration rack structural design that emergent heat radiation structure has been installed to a small part is more complicated, and the complexity of processing, assembly cost, assembly of material is all higher, and degree of automation is lower is solved to this embodiment. And still improved the integration rack of having installed emergent heat radiation structure in the market and reduced the inside holistic leakproofness of rack, great gap appears when emergent heat radiation structure does not start, leads to the defect that the refrigerating system effect of rack inside descends. Further, this embodiment still can monitor the inside temperature of rack automatically to judge according to the temperature condition is automatic after the monitoring, when the inside temperature of rack surpassed preset temperature threshold value, the emergent heat radiation structure of automatic start or close.

It is to be understood that the above-described embodiments are merely illustrative of some, but not restrictive, of the broad invention, and that the appended drawings illustrate preferred embodiments of the utility model and do not limit the scope of the utility model. This application is capable of embodiments in many different forms and is provided for the purpose of enabling a thorough understanding of the disclosure of the application. Although the present application has been described in detail with reference to the foregoing embodiments, it will be apparent to one skilled in the art that the present application may be practiced without modification or with equivalents of some of the features described in the foregoing embodiments. All equivalent structures made by using the contents of the specification and the drawings of the present application are directly or indirectly applied to other related technical fields and are within the protection scope of the present application.
