Car and boat waste heat refrigerator and interior environment system

The invention belongs to the ammonia gas diffused absorption type fridge equipment.

It is noticeable always that the used heat that driving engine is discharged is made the energy of refrigeration air-conditioner, no pump self-loopa ammonia gas diffused absorption type refrigeration has many advantages in the prior art, its resorber as shown in Figure 1, weak aqua ammonia is relied on the dirty and upstream ammonia hydrogen stream 2 of power for support and is contacted from import 1 along coil pipe, absorb ammonia and change strong aqua inflow storage tank 3 into, to coil pipe slope requirement height, the gas-liquid contact surface is little.Acceleration during car and boat are advanced, it can not adapt to slow down, open, stop badness such as upward slope descending such as brake and top ripple vibrations.

The objective of the invention is general economic benefit at above-mentioned shortcoming and engine waste heat utilization, adopt spiral shell rolling resorber in the stand pipe, heat pipe evaporator, unique gas heat-exchanger, engine exhaust used heat or other thermals source be the producer of power reach car and boat advance in the badness refrigerating air conditioning device that can turn round down.

Feature of the present invention is to manage interior spiral shell rolling resorber as shown in Figure 2, again through liquor preparation disk (4) weak aqua ammonia of radiator (3) cooling back inflow absorber along pipe in spiral shell reel screw off stream from (1) through H Exch (2) by the weak aqua ammonia of producer, spiral shell is rolled up with tube wall and is leaned on elastic force tensioning or thick-walled pipe car tapping to become integral structure.The hollow bulb that ammonia hydrogen stream (5) is rolled up from the end opening feeding spiral shell of tubulation upwards spreads with peripheral weak aqua ammonia and contacts, ammonia be absorbed the remaining hydrogen in back upwards drift be connected to evaporator from (6), dirty strong aqua penetrates the capillary hole pattern and flow to (2) and import producer again.Though be start-stop or sudden stop or advance in acceleration; various badness such as deceleration or upward slope descending are not all upset the passage separately that solution is dirty and diffusion gas drifts about; in extreme the most abominable moment of sudden stop, force of inertia also can only cause solution to gather that a side of spiral shell volume in the pipe is dirty can not destroy gas-liquid passage separately.Absorption refrigeration still can move.Its feature is that also the solution collector tube center line of resorber bottom is to separate with capillary hole pattern (8), first garden is the diffusion gas channel, second garden is a liquid trap, and liquid flows into coned sol storage (2), not disturbing flow passage again by the pore liquid trap that moves on to off the net.

The invention is characterized in heat pipe evaporator, the docking facilities of it and absorption tube and gas heat-exchange tube as shown in Figure 3, the direction shown in hydrogen (6) dotted arrows of empty upwards drift in the absorption tube, the liquefied ammonia limit that heat pipe evaporator pipe week moves down flashes to ammonia and combines ammonification hydrogen (9) with hydrogen and move down, at gas heat-exchange tube (10) row interchange of heat, be characterised in that with being separated in the pipe up and down or two halves garden, the left and right sides, the centre has a separator of battery plates to be separated into two kinds of gas passages, be interspersed with on this dividing plate many needle-like heat conductors stretch to about half garden, upward the ammonia hydrogen of to hydrogen and decline is borrowed the capable interchange of heat of needle-like heat conductor, (12) are injected into the suitable for reading of heat pipe evaporator or are injected by liquor preparation disk from (13) after lowering the temperature the liquefied ammonia that gets off from condenser from (11) to liquid vessel, and the heat pipe-type capillary wick is covered with liquefied ammonia.Move down while evaporating, ammonia steam combines ammonification hydrogen and sinks automatically with hydrogen, liquefied ammonia is arranged in capillary wick in the evaporating tube.Evaporation surface is big, and no liquefied ammonia gathers and can tolerate various badness.

Resorber and evaporator all are to erect comb, structure, type is very thin, can be installed in the shell interlayer of automobile, when just providing a mini-bar for automobile, resorber can be installed in outside side or the operator's compartment back cover, evaporator can be arranged on below the seat, when purpose is during for the operator's compartment air-conditioning, evaporator can be arranged on a left side or the right side of backsight chimney so, resorber below the backsight chimney, the little air port that only need open cold wind during chilling requirement summer, air-flow during garage advances is inswept sends into operator's compartment after the evaporation comb becomes cold wind, only need switch the air port when need warm oneself winter easily and just can lead the outer current of warm air inswept condenser resorber formation of car to cold wind and deliver in the car.Warm and cold air all is from the external cleaning gas tream of car, and the pure and fresh degree that improves atmosphere in the car also is fabulous.

The invention is characterized in that three grades of thermal siphons that utilize engine exhaust used heat promote producer as shown in Figure 4, (1) is the waste hot gas import that driving engine is discharged, pass the third stage (3) second stage (4) first order (5) producer, waste hot gas is discharged outside the car by (2) freeing pipe after reducing temperature step by step.The isolated ammonia vapour of the first order merges with the two or three grade of isolated ammonia vapour through (6) guiding and directs into perforated plat column pipe (9) purification ammonia, the weak aqua ammonia after three grades of separation introduce by (7) liquor preparation disk of sending into resorber after the cooling such as H Exch enter manage in spiral shell rolling resorber such as Fig. 3.Its feature is that also the perforated plat column pipe becomes bifurcation shape, right branch is close to producer, water vapor condensation in the ammonia vapour becomes ammoniacal liquor to import first order producer again, purifying the ammonia removed behind the water vapour import ammonia condenser by left branch, (8) all are provided with umbrella-shaped structure in the visible thermal siphon of Fig. 4, prevent that the mal-condition in garage advances from influencing the normal operation of raising pipe.

Whole refrigerating air conditioning device is without any mechanical power, there are not wearing and tearing, few power consumption source promotes running with exhaust waste heat entirely, utilizes the diffusion of hydrogen to need not throttling control manipulation process, it is innovation to existing diffusion absorption refrigerating machine, its thermodynamic coefficient increases, and the effective volume of refrigerator increases, and has thermal source or used heat all can adopt, need not precision optical machinery processing, particularly to the car and boat practical value height of long-distance running.
