Technical Field
The invention relates to the technical field of heat exchange of an electrical control cabinet, in particular to a simple device for strengthening heat exchange of the electrical control cabinet.
Background
At present, the industrial electric control cabinet mostly adopts a natural ventilation type shell, a heat insulation type shell, an air conditioner arranged at the top of a cabinet machine, a heat exchanger arranged in the cabinet machine and the like to solve the problem of heat exchange in the cabinet. The heat exchange fan of the electrical control cabinet of the distribution room often works due to long-time high load, and the phenomenon that the heat exchange fan burns out to influence the normal operation of equipment appears. Particularly, in winter, the temperature of the electrical control cabinet is relatively high, and the following main reasons are found through data and data demonstration in field: firstly, indoor environment temperature is comparatively warm, and wherein environmental factor such as thermal radiation is more, secondly in special trades such as heating, equipment loads of operation such as converter are great in the cabinet winter, and the heat of production is more, but present general heat transfer fan heat transfer effect is relatively limited, easily appears the abnormal phenomenon that the temperature is higher than the outer temperature of cabinet in the cabinet. The heat dissipation device has the advantages that the heat dissipation device can be found in daily inspection and maintenance work, the traditional fan can achieve temperature control requirements in normal production environment, and cannot achieve expected cooling effect when the dust concentration is too high and the environment temperature is higher.
In order to solve the problems, a simple device for enhancing heat exchange of the control cabinet is designed and is arranged at an air inlet and an air outlet of a heat exchange fan of an electrical control cabinet. The environment air is blown into the cabinet at a relatively high wind speed and a relatively large wind quantity, and the hot air in the cabinet is discharged outwards at a relatively low wind speed and a relatively small wind quantity, form certain "malleation" effect in the cabinet, when solving the heat dissipation problem, stop on-the-spot dust etc. and in the entering control cabinet, stop the dust particle and cause harm to electric original paper in the cabinet. Through theoretical analysis and on-site preliminary test, the device can guarantee the heat dissipation demand in the regulator cubicle to a certain extent and energy-concerving and environment-protective again, and low cost, and the safe risk is low, and it is convenient to install.
Disclosure of Invention
The invention aims to: the simple cabinet body device for the control cabinet to strengthen heat exchange can meet the requirements of energy conservation, environmental protection and improvement on heat exchange efficiency to a certain extent, particularly in special environments such as a heat exchange station and the like, can furthest realize heat exchange of the electrical cabinet, is low in manufacturing cost and maintenance cost, and meets the requirement of interchangeability. Fans with different powers (wherein the power of the fans at the air inlet and the aperture of the air inlet are larger than that of the air outlet at the top) and the device are arranged at the air inlet at the bottom of the electric cabinet body and the air outlet at the top of the cabinet body.
The technical scheme of the invention is as follows: the utility model provides a device for electrical control cabinet reinforces heat transfer, includes cabinet body outer wall, cabinet body inner wall, vent, and the vent includes vent large-section face, vent little terminal surface, has vent large-section face on the cabinet body outer wall, has vent little terminal surface on the cabinet body inner wall.
The ventilation opening is of a hyperbolic structure.
The outer wall of the cabinet body and the inner wall of the cabinet body are partially provided with hollow cold plate interlayers.
The ventilation opening is provided with a fan.
An air inlet device is arranged on the ventilation opening.
The invention has the following remarkable effects:
(1) The heat exchanger is used for the enhanced heat exchange of the electrical control cabinet. The device solves the problems that the heat exchange of the fan of the special environment control cabinet is not timely, and impurities such as dust enter the interior of the special environment control cabinet to influence the normal operation of equipment, realizes energy conservation and environmental protection, and reduces energy consumption;
(2) The device has low cost and convenient installation, meets the interchangeability requirement, and reduces the equipment maintenance cost;
(3) The reliability of the device is improved. This device is through setting up "malleation" heat transfer system in the cabinet, effectively improves the operational reliability of key equipment under the special environment.

Detailed Description
The technical solution of the present patent will be further described in detail with reference to the following embodiments.
A device for strengthening heat exchange of an electrical control cabinet comprises a cabinet body outer wall 1, a cabinet body inner wall 2 and a vent 5, wherein the vent 5 is in a hyperbolic structure and comprises a vent large section surface 3 and a vent small end surface 4, the vent large section surface 3 is arranged on the cabinet body outer wall 1, the vent small end surface 4 is arranged on the cabinet body inner wall 2,
the outer wall 1 of the cabinet body and the inner wall 2 of the cabinet body are partially provided with hollow cold plate interlayers, and secondary heat exchange is carried out by air.
The ventilation opening 5 is provided with a fan and an air inlet device.
The main effect of vent is just the ventilation, realizes gaseous "malleation" in the cabinet, when satisfying normal heat transfer demand, avoids the entering of other dusts such as dust. According to the state equation of the ideal gas;
PV＝nRT
wherein P is pressure, pa, T is system absolute temperature, K, R is ideal gas constant, J/(mol.K), and V is gas volume, m3. A certain amount of gas is compressed, under the condition that the internal and external pressures of the cabinet body are balanced, the temperature of the air entering the cabinet body can be reduced, the cold air entering from the front side of the cabinet body drives the hot air inside to be discharged from the top device of the cabinet body, the top air inlet device is close to the rear wall panel, the large port faces inwards, the air is compressed and discharged again, and the air is circulated in the way to form a positive pressure heat exchange system
