Description
Technical field
Air-conditioning technical field is the utility model is related to, specifically proposes a kind of central air-conditioning electricity for cooling down specified electrical equipment
Control box.
Background technology
At present, the electric-controlled box of in the market central air-conditioning outdoor unit is usually square sheet metal structural, since rain-proof dust-proof needs,
General electric-controlled box leakproofness is relatively preferable.For Large Central Air Conditioning System, especially big connected machine, electrical equipment is more and generates heat
Measure larger.To prevent electric-controlled box internal heat from assembling, air-conditioning normal operation and the reliability of electrical equipment are influenced, usually automatically controlled
Cassette bottom portion opens some apertures, and side opens louvered shutter and adds waterproof cover structure, with reference to figure 1.The cold wind for flowing into electric-controlled box first cools down
Close to the element of air inlet, then cool down other elements.Heat dissipation of this structure to frequency conversion drive has certain limitation, can not ensure
Each element is sufficiently cool, when environment temperature is higher, the excessive protection of actuation temperature easily occurs.
The utility model discloses a kind of fan coil and electric-controlled box, electric-controlled box to include electric-controlled box by CN201620466714.6
Main body, installing plate, fixed plate and cover board, are provided with the first air outlet, the first air outlet court on the first side wall of automatically controlled box main body
To the wind turbine of fan coil, heat emission hole is provided with outer wall, installing plate is used to install electric elements and be connected with outer wall, installing plate
The gap for supplied gas flowing is provided between the first side wall, and venthole is provided with installing plate.By heat emission hole into
The air for entering installing plate side enters the opposite side of installing plate by venthole, is then discharged by the first air outlet, fixed plate
For automatically controlled box main body to be fixed on to the Sheet Metal Part of fan coil, cover board can realize the effect of dustproof and waterproof.It is extraneous
For air from heat emission hole by wind turbine suction electric-controlled box, outside air absorbs the heat of electric elements in electric-controlled box, the sky after heat absorption
Gas is expelled to the outside of electric-controlled box by the first air outlet, so as to achieve the purpose that to cool down to electric elements in electric-controlled box.This reality
Entered with new air-flow in automatically controlled box main body, air is located at the electric elements side of installing plate, and air is absorbed on electric elements
Heat after by venthole enter installing plate the side for being not provided with electric elements, finally by the first air outlet discharge,
The program can reduce the heat on electric-controlled box, but absorbed heat behind its electric elements side by installing plate and become
Hot-air, when which enters back into the side for being not provided with electric elements, its cooling-down effect unobvious.
Outdoor unit is usually divided into two spaces by existing air-conditioner outdoor unit by middle partition plate, one positioned at middle partition plate side
Space sets wind turbine and heat exchanger, and the space is relatively large, and wind turbine inlet and outlet opens wide open state with being in outside outdoor unit；
And a space of middle partition plate opposite side sets compressor and electronic control module, the space relatively small, compressor and electronic control module
Space surrounding is enclosed by middle partition plate and outdoor machine shell, with lying substantially in closed state outside outdoor set cabinet, if frequency conversion
Air-conditioning, electronic control module further include frequency-variable module.Frequency conversion electrical control module is arranged in frequency conversion electrical control box, no matter is freezed or is heated,
During operation of air conditioner, compressor and frequency conversion electrical control module will produce the heat bigger that amount of heat, especially frequency-variable module produce,
It is the position that whole outdoor unit produces temperature highest quantity of heat production maximum, such as radiates not in time, frequency conversion electrical control module cannot be normal
Work is even burnt, and compressor performance and service life, frequency-variable module and compressor temperature can be also influenced when compressor temperature is excessive
Over-temperature protection device can be all triggered when spending high, forces air-conditioning out of service, influences air-conditioning use.Therefore frequency conversion electrical control must be given
Module and compressor heat dissipation, usual frequency conversion electrical control module use both radiating modes：
(1) air-cooled radiator is set to radiate on the frequency conversion electrical control box that frequency conversion electrical control module is set, radiator can be in
Baffle design is in wind turbine and heat exchanger side, and electric-controlled box is erected on middle partition plate, but electric-controlled box is largely still located at compressor
With frequency conversion electrical control module side, radiator can also be arranged on compressor and electronic control module side close to middle partition plate, no matter radiator
That side of middle partition plate is arranged on, the negative pressure pressure difference formed when being all and being operated by wind turbine so that outdoor air leads to through heat exchanger
Cross after radiator or compressor and electronic control module side air are radiated by radiator heat exchange and outdoor unit is discharged by wind turbine；
(2) frequency conversion electrical control module heat dissipating is cooled down by setting coolant loop, and compressor is usually natural heat dissipation and sets
Radiator heat dissipation is put, above-mentioned radiating mode, is all by the heat dissipation that frequency conversion electrical control module and compressor distribute to outdoor unit
Outside.
When frequency conversion electrical control module in existing convertible frequency air-conditioner uses wind-cooling heat dissipating, wind turbine and heat exchanger sections and outdoor unit
Outside is in complete open state, and the negative pressure region that wind turbine is formed when operating is very big, is whole heat exchanger air intake surface, and dissipates
Hot device only accounts for wherein small part, and positioned at the less fringe region of intake of fan blade, thus flow through radiator
Air quantity very little, wind-cooling heat dissipating efficiency is very low, and especially when summer environment temperature is higher, frequency conversion electrical control module often radiates not
Good, when long-time hot operation, easily causes whole system overheat protector and out of service, and frequency conversion electrical control module is for a long time this
Service life is run under operating mode to be shortened, or even can be burnt out, and refrigerant cooling frequency conversion electrical control module, refrigerant temperature and frequency conversion electrical control
Temperature difference when module works is very big, easily condensation is formed on frequency conversion electrical control Modular surface and automatically controlled circuit board, so as to bring
The hidden danger of frequency conversion electrical control module circuitry plate short circuit.
In view of this, the utility model is proposed.
