Abstract
The utility model relates to a radiating structure of an electrical switch cabinet, in particular to a convection radiating mechanism of an electrical switch cabinet, which comprises a cabinet body with a circuit breaker chamber, and is characterized in that an air inlet is arranged on the cabinet body, is arranged below the circuit breaker chamber and is communicated with the circuit breaker chamber; and the top cover of the cabinet body arranged above the circuit breaker chamber is provided with an opening, and the opening is provided with a electricity-free strong air convector. The convection radiating mechanism of the electrical switch cabinet mainly solves the technical problems that the traditional electrical switch cabinet adopts a radiating structure with a fan, is inconvenient to repair and maintain, is not suitable to be controlled, has high energy consumption and the like, adopts an air convection principle, and radiates the switch cabinet under the premise of not increasing the energy consumption.
Description
Technical field
The utility model relates to the heat loss through convection mechanism of the radiator structure of cabinet, particularly a kind of cabinet.
Background technology
Convection current: make temperature be tending towards uniform process by circulating between hot part and the colder part in liquid or the gas.Convection current is the peculiar mode that heat is transmitted in the liquids and gases, gas more obvious than liquid to flow phenomenon.Convection current can divide two kinds of free convection and forced convections.Free convection is natural occurring often, owing to non-uniform temperature causes.Forced convection forms owing to the external influence convection cell stirs.Strengthen liquid or gas flow speed, can accelerate convective heat transfer.
In the existing cabinet, because the switch cubicle inner space is little, the heat that the circuit breaker operation produces is difficult for dispersing, and all needs to take to install draught fan by force additional all the time and solves heat radiation.Take ventilation fan then can bring following several places problem.
One, maintenance is safeguarded inconvenient.Because cabinet can not have a power failure at any time, once fan failure takes place, deal with very trouble, the influence heat radiation.If fan generation leaf abscission drops in switchgear, then can cause bigger interruption of service.
Two, should not control.Circuit breaker is in service because the input of load changes with the running current that withdraws from initiation, and then the heat of Chan Shenging is also all different.Need drop into the fan operation during full load, increase heat radiation; Load does not need fan running again when reducing.So need the Artificial Control fan running, increased operator on duty's work.
Three, increased equipment energy consumption.
Four, in the heat radiation process, bring dust easily into.
The utility model content
The purpose of this utility model is to provide a kind of heat loss through convection mechanism of cabinet, mainly solve existing cabinet and adopt the radiator structure that installs fan additional, maintenance, maintenance inconvenience, should not control and energy consumption high-technology problem, it has adopted the gaseous exchange principle, is the switch cubicle heat radiation under the prerequisite that does not increase energy consumption.
For achieving the above object, the utility model is to realize like this.
A kind of heat loss through convection mechanism of cabinet, it comprises the cabinet with breaker chamber; It is characterized in that: have air inlet on the described cabinet, described air inlet is positioned at the breaker chamber below and is communicated with breaker chamber; The cabinet top cover of described breaker chamber top has an opening, and non-electrical strong type cross-ventilation device is installed on the described opening.
The heat loss through convection mechanism of described cabinet is characterized in that: described non-electrical strong type cross-ventilation device is the turbine ventilated instrument of the graceful privilege electric power in Lip river, and model is the LMT type.
The heat loss through convection mechanism of described cabinet is characterized in that: the connecting portion of described air inlet and cabinet is laid air strainer.
The heat loss through convection mechanism of described cabinet is characterized in that: have a protection network on the described cabinet top cover opening.
By said structure, advantage of the present utility model is: (1) utilizes the non-electrical strong type cross-ventilation device and the air inlet on the cabinet that are arranged at the cabinet top to form the cabinet inner air and outer air to flow phenomenon, convection current produces power makes non-electrical strong type cross-ventilation device constantly rotate to discharge hot gas in the cabinet, has further quickened convection current so again.In case the inside and outside temperature contrast of cabinet reduces, the running of this heat loss through convection mechanism can weaken again.(2) in order to ensure in the heat loss through convection process, the outer filth of cabinet enters in the cabinet with the cabinet outer air, and the connecting portion of described air inlet and cabinet is laid air strainer.(3) in order to ensure non-electrical strong type cross-ventilation device when not turning round, the outer filth of cabinet enters in the cabinet from the convector slit, has a protection network on the described cabinet 1 top cover opening.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
See also Fig. 1, the utility model discloses a kind of heat loss through convection mechanism of cabinet.As shown in the figure: it comprises the cabinet 1 with breaker chamber 11.Have air inlet 12 on the described cabinet 1, described air inlet 12 is positioned at breaker chamber 11 belows and is communicated with breaker chamber 11; Cabinet 1 top cover of described breaker chamber 11 tops has an opening, and non-electrical strong type cross-ventilation device 2 is installed on the described opening.Described non-electrical strong type cross-ventilation device 2 is the turbine ventilated instrument of the graceful privilege electric power in Lip river, and model is LMT type (as: LMT450 is small-sized, LMT600 is medium-sized, LMT750 is large-scale, and numeral spheroid external diameter can be matched according to the cabinet size).
Because the circuit breaker in the switch cubicle breaker chamber produces a large amount of heats in the middle of operation, cause in the cabinet and cabinet outer air temperature contrast, and utilize the non-electrical strong type cross-ventilation device 2 and the air inlet on the cabinet 1 12 that are arranged at the cabinet top to form the cabinet inner air and outer air to flow phenomenon, convection current produces power makes non-electrical strong type cross-ventilation device 2 constantly rotate to discharge hot gas in the cabinet, has further quickened convection current so again.In case the inside and outside temperature contrast of cabinet reduces, the running of this heat loss through convection mechanism can weaken again.
In the heat loss through convection process, cabinet 1 outer filth enters in the cabinet with the cabinet outer air, and described air inlet 12 is laid air strainer with the connecting portion of cabinet 1.
In addition, when not turning round, the outer filth of cabinet enters in the cabinet from the convector slit, has a protection network on the described cabinet 1 top cover opening in order to ensure non-electrical strong type cross-ventilation device 2.
In sum, be preferred embodiment of the present utility model only, be not to be used for limiting practical range of the present utility model, promptly all equivalences of doing according to the content of the utility model claim change and modify, and all should be technology category of the present utility model.
