Figure 29 expand depending on there is shown this point.Plate is provided with the rib 405 of bilateral at this to 401,400, to realize the circulation of air.

The utility model relates to a kind of heat exchanger, and it carries out inner integrated heat conversion by two flow channels driven in adverse current in pipe.

The design of the heat exchanger of plank frame is described below, alternatively also can considers the embodiment of such as flat tube configuration.

Heat exchanger is by a strake sheet to forming, and the half in them has respectively and enters collector or enter the first flow channel that peviform thing is connected, and has and discharge collector or discharge the second flow channel that peviform thing is connected.This plate forms also being connect by two plates relatively put and the demarcation strip group between them.This demarcation strip is used for separating reverse fluid, the right peviform thing be connected to each other of the plate of setting in column forms fluid on the one hand at this and enters collector and be divided into the first single flow channel to make fluid, forms fluid expulsion collector on the other hand and collects from the second single flow channel to make fluid.

The difference of these two plates 311,312 is only the transitional region between plate passage and plate peviform thing, enter in plate 311 to enter between peviform thing at flow channel 313 and fluid at fluid and stamp out flowing connection, and between flow channel 314 and fluid expulsion peviform thing, there is connection in fluid plate 312.

This junction can alternately in plate mould punching press out, and two plates therefore, it is possible to formed with replacing assembly in same mould.It reduce die cost, and improve standard component quantity.

Above-mentioned heat exchanger is by such percolation, namely fluid (such as cold-producing medium or cooling medium etc.) flows in the first plate passage half portion 311 on the first collector (as entering collector) is such as on the upside of module, then be directed in the second plate passage half portion 312 by the Connection Element between two collectors relatively put (being marked on on the downside of module as entering collector and discharging collector), and flow through this passage half portion, again flowed out from this second channel half portion by the second collector (being again marked on on the upside of module as discharge collector) subsequently.

The advantage of this percolation mode is the homogenising (such as evaporimeter) of temperature curve, realized by the homogenising (reason is the heat conversion between two passage half portion) of the different temperatures of reverse fluid on the one hand, realized by the homogenising of the temperature of the air of these two passage half portion of circulation on the other hand.

Connection Element between two on the downside of the module collectors relatively put can refer to independent attaching parts, also or be arranged on there is integrated deflected channel etc. side members in.

When two module misconnection, fluid is assigned to all the first plate passage half portion 311 be arranged in parallel by entering collector simultaneously, and correspondingly continues to be assigned to all second plate passage half portion 312 by Connection Element after deflection.

When multiple module misconnection, fluid is only assigned to the first plate passage half portion 311 be arranged in parallel of some simultaneously, continue to guide to next module after fluid percolation second plate passage half portion 312 before, and before this place proceeds the assigning process the same with the first module again, this fluid directly overflows to plate from a collector towards adjacent collector, such as, by the interface channel of the extrusion between the adjacent collector peviform thing of plate.

This flow channel interchanger (especially plate evaporator) also alternatively with single groove make design, namely can only be provided with a groove on the side of heat exchanger.

The misconnection of individual module can change according to layout and/or embodiment at this.

Pressure reduction is produced according to mass flow or operating point in evaporimeter.

According to pressure reduction, regulate the different absolute pressure between evaporator inlet and outlet and different evaporating pressures.

Its consequence is, compared with the temperature being subordinated to evaporating pressure in outlet, the evaporating temperature on evaporator inlet can be obviously higher when pressure reduction is larger.According to the pressure reduction produced by heat exchanger, therefrom cause the temperature changing process of the cold-producing medium of evaporation.In addition, wish that cold-producing medium is overheated on evaporator outlet at the end of evaporation, to produce stable heat alarm (such as 5K) on injection valve

But herewith create the thermal treatment zone of local on an evaporator, this thermal treatment zone can be passed through adequate measures (such as carrying out multiple misconnection successively in direction of air) and realize homogenising.

Because the heat exchange surface of inside is integrated in evaporimeter on almost whole height, so can the thermal treatment zone of local be down to minimum between the entrance and exit of evaporation oral cavity.

By the conversion of heat on the heat-exchange surface of integrated inside, it is stable overheated to produce in outlet in the cold-producing medium of adverse current between the cold-producing medium entered.Compared with there is the conventional system of multiple misconnection, by the conversion of obviously higher heat, create the much smaller local portion section of evaporimeter.

The temperature flowing through the cold-producing medium of evaporimeter is obviously adjusted to lower average temperature level quickly, and overheated zone can be down to minimum in evaporimeter.Therefrom create the high average thermograde driven, and therefore increase power thereupon.
