Abstract
The invention relates to a heat exchanger which is convenient to disassemble and used for refrigeration; a ring of rigid plates are added at the periphery of an air outlet of an evaporator which is provided with the heat exchanger used for refrigeration, and are glued at the periphery of the air outlet of the evaporator by glue; rectangular closed hole rubber sponge is compacted between the plates and the roof skin of the bus so as to achieve waterproof and sealing effects and overcome the defects that the sealing mode of the air outlet of the overhead part of the refrigerating equipment of the bus is the mode of sponge strips and sealing glue and is not easy to disassemble and assemble and consumes fuel; the two ends of the connecting joint of the evaporator and a condenser are added with two stop valves; the two ends of the connecting joints of the condenser and a high-pressure pipe are added with two stop valves; the two ends of the connecting joint of the evaporator and a low-pressure pipe are added with two stop valves, thus better storing the refrigerants in the pipeline. The heat exchanger is also provided with a condensate atomizer, and utilizes the condensate again, thus improving refrigeration effect; therefore, the heat exchanger has convenient disassembly, saves fuel consumption and has wide application value.
Description
Technical field
The present invention relates to vehicle-mounted refrigerating air conditioner, particularly a kind of easy-to-dismount cooling heat-exchange device.
Background technology
Usually, the passenger vehicle refrigeration air-conditioner is made up of the heat-exchange device that is installed in the refrigeration compressor on the passenger-carrying chassis and is installed in the passenger vehicle top, the top heat-exchange device is fixed on the passenger vehicle top, with bolting and there is binder bonding to prevent that rainwater from irritating into interior, and be connected carrying heat exchange medium with pipeline between refrigeration compressor and the heat-exchange device, and have water pipe connect heat-exchange device to the passenger-carrying chassis position to discharge the condensed water that heat-exchange device must be separated out in the course of the work from air.
Yet Refrigerating for passenger train is with roof heat-exchange device quality heavily about 250Kg, and in the temperate zone and the subtropical zone, use the time of refrigeration air-conditioner shorter in 1 year, generally have only 3-5 month, and passenger vehicle to heavy thing the camel in season of not using refrigeration air-conditioner and travels, and expends fuel.Per 100 km consumes 0.25 liter approximately.
Summary of the invention
Defective at similar technology exists the purpose of this invention is to provide the easy-to-dismount cooling heat-exchange device that is installed in the passenger vehicle top that a kind of fuel saving expends.At the heat-exchange device of pulling down its top season that need not use refrigeration air-conditioner,, reduce fuel consumption to alleviate capacity of body weight.
Technical scheme of the present invention is:
Increasing by a circle around the evaporimeter air outlet has the flat board of rigidity, sticks with glue around the evaporimeter air outlet, and compacting rectangle closed pore rubber-plastic sponge between flat board and the passenger vehicle top covering is to reach the waterproof sealing effect.
Install two stop valves additional at the jointing two ends of evaporimeter and condenser, the jointing two ends of condenser and high-voltage tube install two stop valves additional, and the jointing two ends of evaporimeter and low-voltage tube install two stop valves additional.
Install condensed water atomizing device additional.Condensed water atomizing device links to each other with water pump by water pipe, and the condensate water atomizing that evaporimeter can be produced be sprayed at condenser surface, having increased the radiating effect of condenser, and corresponding raising refrigeration, and the condensed water downcomer need not be installed.
The present invention has following advantage: the sealing means at traditional Refrigerating for passenger train device overhead part air outlet place is the mode that sponge strip adds fluid sealant, be not easy to dismounting, the present invention proposes a kind of new sealing means, increasing by a circle around the evaporimeter air outlet has the flat board of rigidity, stick with glue around the evaporimeter air outlet, compacting rectangle closed pore rubber-plastic sponge between flat board and the passenger vehicle top covering, this sealing means can reach easy disassembly, and waterproof sealing is effective.Install condensed water atomizing device additional, condensed water is utilized once more, improve refrigeration.Pipeline structure in the cooling heat-exchange device also is convenient to dismounting.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a sealing installation diagram of the present invention.
The specific embodiment
The sealing means at compartment air inlet 27 places of traditional Refrigerating for passenger train device is the mode that sponge strip adds fluid sealant.Convenient for guaranteeing demolition, installation, the mode as Fig. 2 is adopted in sealing of the present invention: increase the flat aluminium alloy plate 31 that a circle has rigidity around evaporimeter air outlet 26, stick on around the evaporimeter air outlet 26 with glue 30, compacting rectangle closed pore rubber-plastic sponge 29 between flat board 31 and the passenger vehicle top covering 25 is to reach the waterproof sealing effect.Wherein air outlet frame 28 is the passenger vehicle prior art.
In Fig. 1, in order better to preserve the cold-producing medium in the pipeline, jointing 11 two ends at evaporimeter 15 and condenser 8 install stop valve 10 and 12 additional, condenser 8 installs stop valve 5 and 6 additional with jointing 7 two ends of high-voltage tube 4, and evaporimeter 15 installs stop valve 16 and 18 additional with jointing 17 two ends of low-voltage tube 19.Wherein expansion valve 14 and low-pressure shutoff valve 2 are prior art.
Stop valve is to be used for preserving the interior cold-producing medium of pipeline, and the cold-producing medium overwhelming majority is kept in fluid reservoir 9 and the condenser pipe, all has the part cold-producing medium to exist simultaneously in evaporimeter 15 and the pipeline, and needs to keep the no air of cleaning drying of pipeline.Fluid reservoir 9 is used for storing the cold-producing medium after the liquefaction.
Cooling heat-exchange device unloading process: a closes stop valve 10, starts refrigeration unit; B, machine 1 to be compressed is shut down close compressor stop valve 3 immediately; C closes stop valve 5,6,10,12,16,18; D takes jointing 7,11,17 apart; E unclamps evaporimeter 15 and condenser 8 set bolts, promptly removable evaporimeter 15 and condenser 8 (being cooling heat-exchange device).Condensed water atomizing device 20 and condenser 8 one among the figure, ponding dish 24 and evaporimeter 15 one, condensed water atomizing device 20 is connected by water pipe 21 with water pump 22 centres, and ponding dish 24 is connected by water pipe 23 with water pump 22 centres.
Condensation water reuse method is: the condensed water in the condensed water ponding dish 24 is atomized through water pipe 23 pumps to condensed water atomizing device 20 by water pipe 21 with micro pump 22, blow to condenser 15 with condensating wind again, at condenser 15 surface heat absorption becoming water vapours.
After having dismantled, each stop valve need keep closed condition, and cold-producing medium is stored in fluid reservoir 9 and the condenser pipe, and the pipeline distance between stop valve and the jointing is short as much as possible.Stop valve and joint weak point as far as possible are because pipeline need be discharged air when installing once more, and the space is many can the more cold-producing medium of waste.
During installation, earlier preliminary jointing 7,11,17 unclamps stop valve 5, discharges in the joint 7 and closes stop valve 5 behind the air, tightens joint 7 again; Unclamp stop valve 10, discharge in the joint 11 and close stop valve 10 behind the air, tighten joint 11 again; Confirm to unclamp stop valve 5,6,10,12 after joint 7,11 connects, unclamp stop valve 16 again, discharge in the joint 17 and close stop valve 16 behind the air, tighten joint 17 and affirmation again, unclamp stop valve 16,18,3 successively.Connect condensate pipe.Connect control cable and power cable.
