Abstract
The utility model discloses an integrated air conditioner capable of performing self-controlling on a drive power supply and a control system, relating to the technical field of air conditioners. In the existing cooling system for the drive power supply and control system of a new-energy bus/electric vehicle air conditioner, a cooling fan increases the power load and electromagnetic interference of a control loop, and since an air conditioner shell is provided with an opening directly communicated with the external environment, the problem of hidden trouble in waterproof and dustproof properties of the circuit system exists. The integrated air conditioner disclosed by the utility model comprises a compressor, a condenser, an evaporator, an expansion valve, a liquid storage dryer, an evaporation fan, a condensation fan, a drive power supply and a control system which are arranged in a shell, wherein a partition space is arranged between the drive power supply and the control system, a first air supply pipe is arranged in the shell, one end of the first air supply pipe is communicated with an air return port in an air conditioning chamber, and the other end of the first air supply pipe is close to a frequency converter of the drive power supply. The integrated air conditioner disclosed by the utility model is particularly suitable for the integrated air conditioner of an electric vehicle.
Description
Technical field
The utility model relates to air-conditioning technical field, relates in particular to a kind ofly can carry out to driving power and control system the integrated air conditioner of the self cooled electric bus of interior circulation.
Background technology
Usually, the driving power of electric bus air-conditioning (direct current and AC converter) and control system are overheads.In actual use, because the frequency converter of air conditioner of electric vehicle and control system are in, independently cut off in space, they will be in the face of higher extreme ambient temperature, the highest may be over 60 ℃.And, under extreme ambient temperature, the frequency converter of air-conditioning and control system will frequently break down or self-protection, thereby affect normal use and the service life of air-conditioning system.Therefore, the heat dissipation problem of the frequency converter of air-conditioning and control system just seems extremely important.
Coach motor-car air-conditioning heat dissipation system of the prior art, how additional one or more groups radiator fan in air-conditioner housing, force outside air draft, and the power supply of radiator fan is from the low-tension supply of vehicle control system.Due to the low-voltage control power of the shared vehicle of radiator fan, increased the load of vehicle control power supply, increased the wire harness complexity of vehicle control system, also strengthened the electromagnetic interference to control circuit.Simultaneously, the strong-force exhaust of radiator fan directly is communicated with the car body space outerpace, causes the frequency converter of trolley air conditioner and the hidden danger that there is water proof and dust proof in control system.
Summary of the invention
In cooling system for the driving power of existing new forms of energy big bus air conditioner of electric vehicle and control system, additional radiator fan has increased the power source loads of control loop, also increased the electromagnetic interference of control loop sensor signal, and there is the opening directly be communicated with external environment condition on air-conditioner housing, there is the problem of water proof and dust proof hidden danger in Circuits System, and the purpose of this utility model is to provide a kind ofly can carry out to driving power and control system the integrated air conditioner of the self cooled coach motor-car of interior circulation.
The utility model solves the technical scheme that its technical problem adopts: it comprises compressor, condenser, evaporimeter, expansion valve, drier receiver, evaporation fan, condensation fan, driving power and the control system be arranged in housing, described driving power and described control system have a partition space, be provided with the first ajutage in described housing, one end of described the first ajutage is communicated with the return air inlet in described air conditioning chamber, and the other end of described the first ajutage is near the frequency converter of described driving power.
Further, also be provided with the second ajutage in described housing, an end of described the second ajutage is communicated with the evaporation fan air intake of described air-conditioning, and the other end of described the second ajutage is near the frequency converter of described driving power.
Described the first ajutage and described the second ajutage lay respectively at the both sides of described frequency converter.
Effect of the present utility model is: electric bus integrated air conditioner of the present utility model, set up an air channel that connects air-conditioning evaporation fan air inlet in the isolated area of air-conditioning driving power frequency converter and control system, and another air channel be communicated with return air inlet in air conditioning chamber.By two air channels setting up in the separate cavities in driving power and control system, and utilize the air negative pressure of the return air inlet in evaporation fan air inlet and air conditioning chamber poor, form the cooling blast of the inner automatic cycle of air-conditioning, driving power and control system are carried out cooling, without radiator fan is installed;
In addition, because the air inlet of return air inlet in air conditioning chamber and evaporation fan is fully in air-conditioning inside, the cooling blast of driving power and control system is isolated with external environment condition fully, and dustproof and waterproof is effective, and electrical safety is more reliable.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail;
The partial structurtes schematic diagram that Fig. 1 is the utility model trolley air conditioner.
The specific embodiment
Below will by cited embodiment by reference to the accompanying drawings, describe technology contents of the present utility model and feature in detail.For sake of convenience, hereinafter described " on ", D score is consistent with the upper and lower direction of accompanying drawing, but this can not become the restriction of technical solutions of the utility model.
Illustrate and of the present utility modelly can carry out self cooled integrated air conditioner to driving power and control system in conjunction with Fig. 1, it comprises compressor, condenser, evaporimeter, expansion valve, drier receiver, condensation fan 101, evaporation fan 106, driving power and the control system be arranged in housing 100.Wherein, driving power and control system have a partition space.Be provided with the first ajutage 104 and the second ajutage 103 in housing 100, one end of the second ajutage 103 communicates with the air intake of evaporation fan 106, the other end of the second ajutage 103 is near the frequency converter 102 of driving power, one end of the first ajutage 104 communicates with return air inlet in air conditioning chamber 105, and the other end of the first ajutage 104 is the frequency converter 102 of close driving power also.And the second ajutage 103 and the first ajutage 104 lay respectively at the both sides of frequency converter 102.
(in figure, the direction of arrow means gas flow direction in air-conditioning) as shown in Figure 1, during work, utilize the negative pressure of evaporation fan 106 to pull out wind, by return air inlet 105, the first ajutage 104, the second ajutage 103 forms an air channel, formed natural cooling blast, this cooling blast return air inlet 105 indoor by housing 100 enters, the frequency converter 102 of upwards flowing through, mix by the second ajutage 103 and by evaporation fan 106 air-flow that has passed through heat exchange, enter the interior space of air-conditioning, and then frequency converter 102 and the control system of cooling driving power, without radiator fan is installed.
