Description
Technical field
The utility model belongs to field of air conditioning more particularly to a kind of air conditioning frequency converter cooling device.
Background technology
Convertible frequency air-conditioner has the characteristics that temperature control is accurate, temperature adjustment is rapid, noise is small and energy saving compared with fixed frequency air conditioner.Become
Frequency converter is installed, frequency converter calorific value is very big, therefore need to design radiator and radiate to it inside frequency air-conditioning.Frequency converter
Middle frequency-variable module plays the role of a power conversion and amplification, switching loss and module itself therein in entire frequency converter
Resistance will produce a large amount of heat during the work time, such as these heats are shed not in time, it will seriously affect frequency conversion mould
The performance of block even burns frequency-variable module.
In the prior art there are mainly two types of the radiating modes of frequency converter：One kind is fan+heat radiation type, i.e., leads to frequency converter
Heat conductive silica gel is crossed, cooling fin is transferred heat to, the wind then generated by fan takes away heat.But in many cases,
Limitation and radiator material cost due to product structure space is excessively high, leads to not the temperature of power component being reduced to peace
Complete reliable range.Second board-like for refrigerant pipeline+heat dissipation, i.e., frequency converter transfers heat to heat dissipation by heat conductive silica gel
Plate buries the copper pipe of carrying main refrigerant circuit in heat sink, is finally taken away heat by the refrigerant in copper pipe.It is cold in major loop
Matchmaker has degree of supercooling before entering heat sink, and degree of supercooling can disappear after frequency converter heat sink, not the refrigerant meeting of degree of supercooling
Influence the control accuracy of end expansion valve.
Utility model content
The utility model is radiated for existing frequency converter cooler by air-conditioning main refrigerant circuit, and main refrigerant circuit is caused
Lose the degree of superheat, the technical issues of control accuracy to influence end expansion valve, propose one kind can effectively to frequency converter into
Row heat dissipation, and the cooling device of frequency converter of main refrigerant circuit degree of supercooling is not influenced.
In order to achieve the above object, the technical solution adopted in the utility model is：
A kind of air conditioning frequency converter cooling device, including heat sink are equipped with refrigerant tubing, the refrigerant in heat sink
Pipeline inlet is connected to outdoor unit refrigerant major loop, and throttling set, refrigerant tubing are provided between inlet and major loop
Liquid outlet is connected to gas-liquid separator, and pressure sensor and temperature sensor are equipped between liquid outlet and gas-liquid separator.
Preferably, the throttling set is electric expansion valve.
Preferably, the refrigerant tubing is the copper pipe of bending arrangement.
Originally it is that utility model also proposes a kind of air conditioner, includes the indoor heat exchanger connected by refrigerant tubing, room
Outer heat exchanger, four-way valve, compressor, gas-liquid separator, further include frequency converter, and frequency converter side is equipped with above-mentioned cooling dress
It sets.
Compared with prior art, it is with good effect the advantages of the utility model：
Cooling device of frequency converter described in the utility model draws sub-fraction refrigerant on air conditioner coolant major loop, and leads to
Electric expansion valve throttling is crossed, is radiated for frequency converter using the sensible heat of this sub-fraction refrigerant, refrigerant finally flows into gas-liquid separator
In, which not only can effectively cool down frequency converter, and not influence the degree of supercooling of refrigerant major loop.The air conditioner major loop
In refrigerant have degree of supercooling always, enter heat hand over before expansion valve when can reduce gaseous coolant to expand valve passage occupancy,
Promote the accuracy of expansion valve control.
