Thermograde always only appears at the inside of compartment, also appears in an identical manner in all compartments.If it is identical that supposition refrigerant enters the temperature of leaving heat exchanger component in the heat exchanger component or heavily again, as between the outlet link position of a common inlet link position and nethermost heat exchanger component with uppermost heat exchanger component in the heat exchanger that is connected in series element, people just can find out so, the thermograde of utilizing heat exchanger of the present invention correspondingly to produce a compartment inside is better than common frame mode, this stronger gradient also causes a kind of integrally stiffened hot-fluid in cooling chamber inside, therefore on average causes a kind of even temperature more to distribute.
The heat exchanger component of evaporimeter of the present invention is preferably realized with the spool frame mode.But, because in being equipped with the refrigerating appliance of evaporimeter of the present invention, between compartment, need not hot-fluid,, so within the scope of the invention, also can the employing form be the heat exchanger component sealing wall type, that allow the plate that refrigerant flows through so that realize the temperature balance.
According to first preferred configuration of the present invention, a public throttle point is located at before the supply pipe, and this public throttle point makes the refrigerant of all heat exchanger components together reduce pressure (Entspannung).Therefore, refrigerant is present in the supply pipe with gaseous state basically, and its pressure is all identical at the inlet tie point of each heat exchanger component.
As selection, can between supply pipe and each heat exchanger component, be provided with a throttle point.
Preferably, the public supply pipe allow cross section that refrigerant flows through less than the cross section that flows through of heat exchanger, and the cross section that flows through of this heat exchanger is less than the cross section that allows refrigerant flow through of public suction line.
Supply pipe and/or suction line preferably have a suction pipe (Steigrohr) perpendicular to the heat exchanger component layout respectively.
In addition, preferably side direction connects an input pipe or efferent duct on the suction pipe of supply pipe and/or suction line, and the suction pipe prolongs downwards, exceeds the link position of input pipe or efferent duct and heat exchanger component.The extension of this suction pipe serves as separator or a surge volume, and its is collected liquid refrigerant and guarantee only to allow the refrigerant of gaseous state flow through heat exchanger component or arrival thus and is connected to compressor on the suction line.
Description of drawings
Other features and advantages of the present invention are by with reference to the accompanying drawings the explanation that embodiment did being provided.
Accompanying drawing is represented:
The perspective view of Fig. 1 evaporimeter of the present invention;
The schematic diagram of the refrigerating appliance of Fig. 1 evaporimeter is housed in Fig. 2.
The specific embodiment
Evaporimeter shown in Fig. 1 comprises a plurality of tabular evaporator elements 1 in known mode own, they are made of a zigzag pipe 2 respectively, the detour of pipe is stablized by the wire rod 3 in many root beads jail and is reinforced, and only exemplarily shows two wire rods among Fig. 1 on nethermost evaporator element 1.
The top of pipe 2 and terminal constitute a link position 4 or 5 respectively, and the pipe 2 of evaporator element 1 leads to a suction pipe 6 or 7 at this link position, and this suction pipe linearly extends perpendicular to the plane of evaporator element 1.The internal diameter of each suction pipe 6,7 is mutually the same and be than the internal diameter of pipe 2 mostly doubly.
A bit, a capillary 8 leads to described suction pipe 6 near the upper end of suction pipe on the height of the highest link position 4 or above it.On the height of minimum link position 5 or below it, the outlet 9 with bigger free diameter is connected with suction pipe 7 at the lower area of suction pipe.Because the position of capillary 8 and outlet 9 is on the opposite end of suction pipe 6,7, the pressure reduction between the link position 4,5 of each heat exchanger component 1 is identical, and correspondingly, the refrigerant flow of all heat exchanger components 1 is also identical with cooling capacity.
Two suction pipes 6,7 surpass its minimum separately link position and prolong downwards, that is, under suction pipe 6 situations, surpass the tie point 4 of nethermost evaporator element 1, and under suction pipe 7 situations, surpass the link position 5 or the tie point of outlet 9.The extension 10 of suction pipe 6 is on the one hand as separator; can collect not evaporatively the possible residue of the refrigerant of discharging from capillary 8 in it; so residue just needn't flow through one of them pipe 2 and can not cause noise in the case; or on the other hand as buffer; refrigerant is condensation thereon; when the compressor that connects is temporarily shut down, in the cryogen circuit heating of evaporimeter is housed and makes refrigerant in other position evaporation.11 identical buffering purposes of the extension of suction pipe 7, or when not having extension 10, collect the liquid cryogen of discharging from pipe 2.
