Abstract

The utility model relates to a dual purpose vertical pot-type heat exchanger for an evaporator and a condenser, which comprises an outer housing and an inner housing, wherein a water-discharging opening is arranged at lower side of the outer housing, a water-feeding opening is arranged at upper side of the outer housing, a heat exchange copper pipe is winded in a space I between the inner side of the outer housing and the outer side of the inner housing; and the inner housing is arranged in the outer housing, an oil return hole is arranged at bottom of the inner housing, a gas return hole is arranged at top of the inner housing, an air inlet pipe is arranged at bottom of the inner housing and is connected with a space II of the inner housing, and an air outlet pipe is arranged at lower side of the outer housing and is connected with the space I between the inner side of the outer housing and the outer side of the inner housing. The utility model has the advantages of enlarging application scope for high efficient pots, effectively saves materials, guaranteeing security of sets, prolonging service life of machines, ensuring oil return of sets, reducing oil stored in the system, and increasing heat exchange efficiency.

Description

Evaporator-condenser dual-purpose vertical tank type heat exchanger

Technical field

The utility model relates to a kind of heat exchanger, relates in particular to a kind of this Tube Sheet of Heat Exchanger line structure.

Background technology

Vertical tank type high-performance heat exchanger in the market, the advantage of this heat exchanger: one, volume ratio is less, is divided into outer wall and inwall, and the centre is to fill copper pipe, and copper pipe becomes compact more under special process processing, and the gap is little.And simplify the body mounting structure, and save production process, alleviate the after-sales service difficulty.Two, in high-pressure system, the delivery temperature aspect, this heat exchanger rotation pouring is downwards comprehensively penetrated, and built-in high pressure reservoir (the inwall mid portion can the reduce the system architecture cost) system of reaching does not have oppressive, guarantees that oil return is freely suitable, reinforced platoon's aspiration thermal effect.The aspect, water route adopts the efficient pipe of thickening, and the design of heavy caliber water route guarantees that current are unimpeded, strengthens wear-resistant, the corrosion-resistant influence of pipeline, and Energy Efficiency Ratio is effectively improved.

Its concrete structure is as shown in Figure 1: shell body 1, inner housing 2 (bottom has return-air hole), escape pipe 3, filling pipe end 4, air inlet pipe 5, the following mouth of a river 6, heat exchange copper tube 7 (in the I of space, space II is the space of inner housing among the figure), bottom return-air hole 8; Though this vertical efficient pot type heat exchanger has above advantage, but shortcoming is also very obvious, and it can only be as condenser, and refrigerant can only enter from 5 air inlet pipe, go out from 3 escape pipes, could guarantee the oil return of system like this, if oppositely, refrigerant enters from 3 escape pipes, go out from 5 air inlet pipe, will be in jar trapped fuel, cause system's instability, even may cause that the compressor oil starvation burns.

Summary of the invention

The utility model technical issues that need to address have provided a kind of evaporator-condenser dual-purpose vertical tank type heat exchanger, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: a shell body; The mouth of a river under other arrangement the under the side on the shell body, filling pipe end are placed on the side on the shell body other, and heat exchange copper tube is in the space I between the shell body inboard and the inner housing outside; Also comprise: in shell body, the bottom has the inner housing that spill port, top are opened return-air hole; An air inlet pipe is placed in the bottom of inner housing, links to each other with the space II of inner housing, and an escape pipe is placed in the side-lower of shell body, links to each other with space I between shell body inboard and the inner housing outside.

Compared with prior art, the beneficial effects of the utility model are: make efficient jar enlarge the scope of using, effectively economical with materials; Guarantee the security of unit, prolonged service life of a machine; Guarantee the oil return of unit, intrasystem trapped fuel is reduced, improved heat exchange efficiency.

Description of drawings

Fig. 1 is a vertical tank type high-performance heat exchanger structure chart in the prior art;

Fig. 2 is the utility model structure chart;

Fig. 3 is the schematic diagram of the utility model as evaporator-condenser dual-purpose; Among the figure: on behalf of evaporimeter, A flow to, and another is fried in shallow oil a representative condenser and flows to.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

As seen from Figure 2: the utility model comprises: a shell body 20; Be placed on the side on the shell body 20 otherly at 60, one filling pipe ends 80 in the mouth of a river under other arrangement the under the side on the shell body 20, heat exchange copper tube 90 is in the space I between shell body 20 inboards and inner housing 30 outsides; Also comprise: in shell body 20, the bottom has the inner housing 30 that spill port 40, top are opened return-air hole 10; An air inlet pipe 50 is placed in the bottom of inner housing 30, links to each other with the space II of inner housing 30, and an escape pipe 70 is placed in the side-lower of shell body 20, links to each other with space I between shell body 20 inboards and inner housing 30 outsides.

The utility model is as condenser, refrigerant enters from air inlet pipe, goes out from escape pipe, oppositely, refrigerant enters from escape pipe, go out from air inlet pipe, at this moment, in the bottom of inner housing because the spill port that increases newly has just played decisive role, can make inside and outside connection, trapped fuel can be flowed to low-pressure side, get back to compressor, guaranteed the security of unit.(as shown in Figure 3)

Make the operation that unit can safety, it is fully lubricated to guarantee that compressor can access.Unit is in the process of operation, and other parts can not trapped fuel except that compressor.The utility model is exactly by summing up the experience of practical operation, through improving structure, the efficient jar after the feasible change does not have trapped fuel as condenser and evaporimeter when the application of source pump, lubricating oil can both be got back to compressor smoothly, guarantees the safety of whole system.

Claims

1. an evaporator-condenser dual-purpose vertical tank type heat exchanger comprises: a shell body; The mouth of a river under other arrangement the under the side on the shell body, filling pipe end are placed on the side on the shell body other, and heat exchange copper tube is in the space I between the shell body inboard and the inner housing outside; It is characterized in that also comprising: in shell body, the bottom has the inner housing that spill port, top are opened return-air hole; An air inlet pipe is placed in the bottom of inner housing, links to each other with the space II of inner housing, and an escape pipe is placed in the side-lower of shell body, links to each other with space I between shell body inboard and the inner housing outside.
