Description

Technical Field

[0001] The invention belongs to the technical field of condensers, and in particular relates to a condenser used in a refrigeration system. Background Art

[0002] The condensers of the current refrigeration system can be divided into three categories according to the condensation method: water-cooled condensers, air-cooled condensers, and evaporative condensers. Among them, the evaporative condenser has a stronger cooling capacity and is often used in large refrigeration systems.

[0003] The evaporative condenser commonly used in refrigeration systems has a gas-liquid mixture as the medium in its serpentine coil, which severely scours the pipeline and requires regular maintenance. In addition, there are problems such as nozzles being easily blocked, nozzles being easily detached, and water collectors being easily collapsed. There is also the need for regular sewage discharge and regular cleaning of the evaporative condenser, resulting in high operating and maintenance costs. In order to reduce the amount of refrigerant charged, some refrigeration systems use plate heat exchangers, but traditional plate heat exchangers have the problem of uneven liquid separation leading to low heat exchange efficiency. The present invention describes a new plate heat exchanger that can solve the problem of uneven liquid separation in traditional plate heat exchangers, which will greatly improve the current application status of plate heat exchangers in refrigeration systems and realize the large-scale application of plate heat exchangers in larger-scale refrigeration systems, which will not only save costs but also greatly improve the operating safety of refrigeration systems. Summary of the invention

[0004] The present invention provides a condenser for a refrigeration system, which solves the above problems.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] A condenser for a refrigeration system of the present invention comprises a condenser body, wherein the condenser body comprises a plurality of plate exchanges arranged vertically and equidistantly between an upper fixed plate and a lower fixed plate, and an outer side portion between adjacent upper and lower plate exchanges surrounds to form a "Y"-shaped fin, so that a receiving cavity structure is formed between adjacent upper and lower plate exchanges, and at least one group of refrigerant circulation channels and one group of hot air circulation channels are opened in the condenser body, and each group of the refrigerant circulation channels and the hot air circulation channels comprises two vertical channels opened vertically in the condenser body;

[0007] A refrigerant liquid outlet is arranged on the outside of the upper end of one vertical channel of the refrigerant circulation channel, and a refrigerant liquid inlet is arranged on the outside of the lower end of the other vertical channel; a shunt pipe is arranged on the upper ends of the two vertical channels, and the shunt pipes are circulated and exchanged through the guide holes arranged inside the plate exchanger, and the guide holes are arranged in the plate exchanger at the same height as the shunt pipe.

[0008] A hot air inlet is arranged outside the upper end of one vertical channel of the hot air circulation channel, and a condensate outlet is arranged outside the lower end of the other vertical channel;

[0009] The vertical channels between adjacent upper and lower plates in the refrigerant circulation channel and the hot air circulation channel are welded with closed rings in a spaced-around manner, and the closed rings of the refrigerant circulation channel and the hot air circulation channel are arranged in an alternating manner. The closed rings of the two groups of vertical channels of the refrigerant circulation channel or the two groups of vertical channels of the hot air circulation channel are arranged in the same layer.

[0010] Furthermore, the closed ring adopts a circular ring structure with the same inner diameter as the vertical channel, and the channels of the upper and lower adjacent plates are replaced at the positions of the vertical channel to achieve closed-loop closure on the circumferential side.

[0011] Furthermore, the diverter pipe is a tubular structure with an outer diameter the same as the inner diameter of the vertical channel, and openings connected to the guide holes are evenly arranged around the circumference of the diverter pipe.

[0012] Furthermore, the diameter of the guide hole is smaller than the thickness of the plate.

[0013] Furthermore, refrigerant or hot air or condensed water formed by condensation of hot air is stored in the cavity between the plate exchanger and the "Y"-shaped fins in the condenser body.

[0014] Furthermore, the condensing agent connected to the refrigerant circulation channel is stored in the cavity between the plates in the refrigerant circulation channel without a closed ring in the condenser body and in the cavity between the "Y"-shaped fins with a closed ring in the hot air circulation channel.

[0015] Furthermore, hot air connected to the hot air circulation channel is stored in the cavity between the plates in the hot air circulation channel without a closed ring in the condenser body and in the cavity between the "Y"-shaped fins with a closed ring in the refrigerant circulation channel.

[0016] A working method for a condenser of a refrigeration system, wherein a refrigerant enters a refrigerant circulation channel through a refrigerant liquid inlet, and circulates through two vertical channels through a shunt pipe at the upper end and a guide hole in a plate exchanger. During this process, the refrigerant is also located in a cavity between plate exchanges that are not provided with a closed ring in the refrigerant circulation channel, and in a cavity between "Y"-shaped fins that are provided with a closed ring in a hot air circulation channel;

[0017] The hot air enters the hot air circulation channel through the superheated air inlet, and circulates through the two vertical channels through the cavity channel between the two plate exchanges without closed rings. During this process, the hot air is also located in the cavity between the plate exchanges without closed rings in the hot air circulation channel, and in the cavity between the "Y"-shaped fins with closed rings in the refrigerant circulation channel.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Compared with the common condenser, the present invention has a greatly increased condensation contact surface, a faster condensation speed, and a greatly improved condensation effect after calculation;

[0020] 2. The present invention adopts a unified plate exchange layer in the condenser to separate the chambers for the flow and mutual contact of the refrigerant and the hot air. The chambers are staggered in design, which greatly increases the contact and heat exchange area between the refrigerant and the hot air and improves the condensation efficiency.

[0021] 3. The amount of refrigerant required for the condenser of the present invention is greatly reduced. Often, a conventional refrigeration system has a charging amount of more than ten tons, while the charging amount of the present invention is only a few kilograms. It is not necessary to transport too much refrigerant, which will save a lot of electricity costs and reduce investment during operation.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
