Description
Technical field
The utility model is related to the air-conditioning units of the air-conditioning system of excavator more particularly to excavator air-conditioning system.
Background technology
Excavator is one kind of engineering machinery, is widely used in the engineering fields such as building, road, mine, main function be into
Row digging operation.In order to promote the comfort level of driver in driver's cabin, being generally also equipped on board a dredger can be made
Cold and heating air-conditioning system.
Excavator air-conditioning system generally includes mainly compressor, condenser, liquid storage device, evaporator（It is cooling）, steam air heater
（Heating is used）, air blower etc., the low-temperature low-pressure refrigerant gas in evaporator after heat absorption evaporation after compressor sucking compression,
Become high temperature and high pressure gas and be sent into condenser, condensed device carries out heat exchange with surrounding air, becomes high temperature high pressure liquid, stores
In liquid storage device and after being dried, by expansion valve expenditure and pressure, become low pressure refrigerant and enter in evaporator to vaporize, through evaporation
Device absorbs the heat of in-vehicle air, becomes low temperature low pressure gas, and sucked again by compressor, and steam air heater then utilizes engine
The heat of circulating cooling liquid is interior heats.
In excavator air-conditioning system as described above, air blower, evaporator, steam air heater and essential electrical component（Example
Such as blower motor）As air-conditioning unit, it is generally disposed in the driver's cabin of excavator, and compressor, condenser and liquid storage
Device etc. is generally disposed at outside driver's cabin.
On current small excavator market, the power supply for providing voltage for electric components such as drive motors is main
There are two kinds of styles of 12V and 24V.Thus, correspondingly, existing mini-excavator is also primarily present two types, that is, has both existed suitable
For the excavator that vehicle voltage is 12V, there is also the excavators suitable for vehicle voltage for 24V.
Unquestionably, for the excavator of different voltages, it is necessary to match the air-conditioning system of different voltages style, especially
The air-conditioning unit for accommodating essential electrical component, is suitable for both voltages so also there is in the market（12V and 24V）'s
Air-conditioning unit.Due to the limitation of the difference and idle call electric components of vehicle style, air-conditioning producer generally all can be by two kinds of electricity
The air-conditioning unit of pressure type sample is designed to different shapes.
That is, corresponding voltage is the vehicle of 12V, air-conditioning producer will make a kind of air-conditioning unit, and corresponding voltage is
The vehicle of 24V, air-conditioning producer make another air-conditioning unit again.This is primarily due to the vehicle for different voltages style,
The installation dimension of its applicable electric components is all different at present, and the shape for thereby resulting in two kinds of air-conditioning units is different, thus
Its shell can also be made into different styles.
And the shell of air-conditioning unit is generally resin or pressing products.Currently, from light-weighted angle, it is main
Stream is the shell using resin material.Due to being suitable for two kinds of voltages as previously described（12V and 24V）Air-conditioning unit shell
Style is different, therefore air-conditioning producer is required to develop two sets of resin-cases to correspond to the demand in market.This means that air-conditioning factory
Family needs to put into two molds, costly, and prodigious cost pressure is caused to air-conditioning producer.This part expense can be married again finally
To terminal consumer, checked by consumer.
