Problems solved by technology

If it is directly applied to shaking equipment such as ship engines, it will easily cause the problem of unstable liquid supply to the condenser, causing a gas ring in the unit and affecting the cooling effect
[0003] On the other hand, since the existing Freon condenser has no anti-corrosion measures, the use of seawater for cooling water will also cause corrosion of equipment

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0015] Such as figure 1 As shown, the present invention includes a cylinder 9, which is supported by two supports 20 and placed therein. Both ends of the cylinder 9 are respectively welded with a tube plate 6 , and the outer end of the tube plate 6 is connected with a head 3 with a flange 5 through bolts 18 . Both end caps 3 are provided with an air release interface 4, a water discharge interface 17 and a zinc rod 2 for anticorrosion. The head at one end is provided with a water inlet pipe 1 and a water outlet pipe.

[0016] The anti-corrosion zinc rod 2 is threadedly connected to the inner cavity of the head 3 at both ends through a taper joint.

[0017] When the cylinder 9 is welded to the tube sheet 6, a liner 7 needs to be placed inside the cylinder 9 to prevent welding slag from falling into the cylinder.

[0018] The upper part of the cylinder 9...

Abstract

The invention discloses a Freon condenser for ships, which comprises a cylinder (9) of which the lower part is provided with more than two liquid outlet ports (21); the liquid outlet ports (21) are respectively connected with a liquid bag (23) through liquid outlet pipes (22); and the liquid bag (23) with a drain pipe (24) is fixedly arranged on the bottom of the cylinder (9). Refrigerant gas enters the condenser through a gas inlet pipe on the upper part of the condenser, is subjected to gas homogenizing treatment by a gas baffle plate, and exchanges heat with a heat exchange pipe in the cylinder, so that the refrigerant gas is condensed into liquid and converged on the bottom of the cylinder. When the condenser is inclined toward any direction, refrigerant liquid on the bottom of the cylinder can be converged into the liquid bag finally through a plurality of liquid outlet pipes and is discharged through the drain pipe on the bottom of the liquid bag. The condenser has stable liquid supply, and ensures refrigerating effect.

Description

(1) Technical field [0001] The invention relates to a freon condenser, in particular to a marine freon condenser with a horizontal shell and tube type. (two), background technology [0002] All kinds of Freon condensers in the refrigeration system are designed according to the conditions used on land. If it is directly applied to shaking equipment such as ship engines, it will easily cause the problem of unstable liquid supply to the condenser, causing a gas ring in the unit and affecting the cooling effect. [0003] On the other hand, since the existing Freon condenser has no anti-corrosion measures, the use of seawater for cooling water will also cause corrosion of the equipment. (3) Contents of the invention [0004] The present invention aims to provide a marine freon condenser to overcome the aforementioned defects of the existing freon condensers. The technical problem to be solved is to ensure that the condenser can still supply liquid outward stably when it shake...
