Description

Technical Field

[0001] This utility model relates to the field of heat exchangers, specifically a high-efficiency heat exchanger with anti-condensation properties. Background Technology

[0002] Currently, the heat exchangers used on ships have relatively simple enclosure structures, with unsatisfactory sealing between the doors and frames, and a non-compact structure. The water trays are assembled into the base, resulting in gaps and potential air and water leaks. Furthermore, the surface coolers are generally installed perpendicular to the air intake direction within the heat exchanger, leading to low thermal efficiency and poor sealing. Summary of the Invention

[0003] This invention provides a high-efficiency heat exchanger with a simple structure, good overall sealing, and the ability to effectively balance high heat exchange efficiency and prevent condensation leakage.

[0004] The technical solution adopted by this utility model is as follows: a high-efficiency heat exchanger with anti-condensation, including a box body, characterized in that: both sides of the frame columns and side beams of the box body are bent inward to form a stop groove, and a locking nut is welded in the stop groove. The stop groove extends inward and upward to form a sloping groove edge. The side surface of the box body (excluding the bottom surface) and the inner side of the top panel are provided with a sealing strip that abuts against the sloping groove edge, and the panel is bolted and locked to the locking nut. The outer side of the sloping groove edge on both sides of the same column or side beam is fitted with corner insulation cotton that matches and fits the insulation cotton layer on the panel. The bottom surface of the box body adopts a water-receiving tray structure. The inner side of the water-receiving tray abuts against the sloping groove edge through a sealing strip and is bolted and locked to the locking nut. Air inlets and air outlets are provided on opposite sides of the box body. The air outlet is provided with a water-blocking structure. A surface cooler is obliquely placed inside the box body. The lower end of the surface cooler is supported on the side of the water-receiving tray corresponding to the air inlet. The upper end of the surface cooler is connected to the bottom of the top panel on the side corresponding to the air outlet.

[0005] The surface cooler is connected to the liquid inlet and liquid outlet on the side of the casing.

[0006] The water-blocking structure includes multiple water-blocking plates, which are vertically arranged at even intervals in the air outlet along the direction perpendicular to the air outlet. Each water-blocking plate includes an outer plate, an inner plate, and a middle plate. The outer plate and the inner plate are connected at an obtuse angle. The connecting end of the outer plate and the inner plate is connected to the outer side of the middle plate. The inner side of the middle plate extends to the position of the corresponding inner plate. The inner side of the middle plate of the next water-blocking plate extends along the air outlet direction to the space between the inner and outer plates, and there is an air outlet gap between it and the inner plate of the previous water-blocking plate.

[0007] The water-blocking structure is partially positioned above the water-receiving plate in the vertical direction.

[0008] The columns and side beams are angle profiles, with the two sides of the angle profiles bent outwards to form a stop groove and a beveled groove.

[0009] The air outlet is made of stainless steel.

[0010] The water-blocking structure is made of stainless steel.

[0011] The locking nut is made of 316 stainless steel.

[0012] The water-receiving tray is fully welded to the four side beams at the bottom of the frame.

[0013] The water-receiving basin is connected to an external drainage pipe.

[0014] The beneficial effects of this utility model are:

[0015] 1. Compared to the traditional method of installing a water tray on the inner bottom, the water tray is directly connected and fully welded as the bottom surface of the tank. This simplifies the structure and effectively avoids the assembly gaps caused by installing a water tray on the inner bottom, thus solving problems such as loosening and leakage of the built-in water tray.

[0016] 2. The uprights and side beams of the frame all adopt the outer extension groove and beveled edge of the angle profile, which can strengthen the connection and support when assembling the side and top panels. At the same time, it works with the sealing strip on the inner surface of the panel to abut against the beveled edge, enhancing the sealing performance of the panel installation. In addition, corner insulation cotton is integrally stretched on the outer side of the beveled edge, which can cooperate with the insulation cotton layer on the panel to further improve the overall sealing performance at the corner and the connection of the panel.

[0017] 3. The use of an inclined surface cooler can increase the heat exchange efficiency within a certain height of the enclosure.

[0018] 4. The water-blocking structure uses multiple water-blocking plates, which can effectively block water vapor and condensation brought out by the air outlet. The acute angle between the middle baffle and the inner baffle can further improve the water-blocking effect. After water is blocked, it falls directly into the water collection tray for collection, thus improving the overall water-blocking effect of the air outlet. Attached Figure Description
