Abstract

The utility model relates to an efficient shell-and-tube condenser, which comprises a condenser body. A guide plate is arranged between the upper portion and the lower portion of a condenser tube in the condenser body. The efficient shell-and-tube condenser has the advantages that liquid refrigerant condensed by the upper portion of the condenser tube can be guided to the edge of a shell, the heat exchange efficiency of the lower portion of the condenser tube can be greatly improved, the design is extremely effective for a large-tonnage unit, and the condensing temperature can be reduced by about 0.5-1 DEG C.

Description

The heavy duty detergent shell-and-tube cooler

Technical field

The utility model relates to a kind of heavy duty detergent shell-and-tube cooler, relates in particular to the structure of this heavy duty detergent shell-and-tube cooler.

Background technology

Visible by Fig. 1: as to comprise in the refrigeration plant that compressor 1, condenser 2, coolant throttle device 3, economizer 4 and evaporimeter 5 form.Wherein the major function of condenser is to let refrigerant be condensed into liquid state by gaseous state; In this phase transition process; Refrigerant need be emitted a large amount of latent heat, makes cooling medium such as the water or the bittern of heat exchange with it, when the condenser condensation of refrigerant; So condenser is meant that cold-producing medium (refrigerant) carries out a kind of heat exchanger of condensation therein, and its objective is condensation of refrigerant.

In the bittern unit that handpiece Water Chilling Units that large-scale central air-conditioning uses or large-scale freezing unit use, its condenser mainly is a shell-and-tube cooler.

Visible by Fig. 2: the liquid refrigerants of condenser the first half condensation can drop in the outer surface of the latter half condenser pipe, thereby has significantly reduced the heat exchange efficiency of time half storey condenser pipe, as far as the large-tonnage unit, will cause condensation temperature higher.

Summary of the invention

The utility model technical issues that need to address have provided a kind of heavy duty detergent shell-and-tube cooler, are intended to solve the above problems.

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

The utility model comprises: the condenser body; Between two parts deflector is set up and down at the intrinsic condenser pipe of described condenser.

Compared with prior art; The beneficial effect of the utility model is: can will be guided to shell rim by the liquid refrigerants of the first half condensing tube condensation; Can significantly improve the heat exchange efficiency of the latter half condenser pipe; As far as the large-tonnage unit, this design very effectively can reduce by 0.5 ℃-1 ℃ of condensation temperature approximately.

The specific embodiment

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

Visible by Fig. 3, Fig. 4: the utility model comprises: condenser body 50; Condenser pipe in described condenser body 50 is provided with deflector 51 between two parts up and down.

Increased a piece deflector in the utility model, gaseous coolant sucks condenser by the compressor air-discharging end, is diverted to through coolant distribution plate 52 and carries out condensation on the condenser pipe Guan Zhen.This heavy duty detergent condenser is divided into up and down two parts with condenser, in the middle of deflector is set, the liquid refrigerants of the first half condensing tube condensation is guided to shell rim.

Claims

1. a heavy duty detergent shell-and-tube cooler comprises: the condenser body; It is characterized in that: between two parts deflector is set up and down at the intrinsic condenser pipe of described condenser.
