Description

Technical Field

[0001] This utility model belongs to the field of marine heat dissipation technology, and in particular relates to a heat exchange device for heat dissipation and cooling of the internal control system of a ship suitable for marine and other salt spray environments. Background Technology

[0002] Control systems for marine vessels and other applications require operation in sealed environments. Many power devices generate significant heat and experience high temperature rises during operation, necessitating heat dissipation for proper functioning. Currently, heat dissipation primarily includes liquid cooling and air cooling. Due to its higher efficiency, liquid cooling is widely used for many high-power components, with water cooling being the most prevalent application.

[0003] Commonly used gas-liquid heat exchangers can conduct heat from the air inside a sealed cavity to the outside for heat dissipation. However, the components of such heat exchangers are assembled separately, resulting in high contact thermal resistance and low efficiency. Summary of the Invention

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a heat exchange device for ships that can meet the heat dissipation requirements of the control system, ensure the normal operation of the equipment, and avoid failures or performance degradation caused by overheating.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A heat exchange device for ships includes a base plate, a fin assembly, and a sprue. The base plate includes a body and a cover plate. The body has a groove, and one side of the body is fixedly connected to the cover plate, forming a flow channel between the groove and the cover plate. The other side of the body has a fin assembly. The base plate is connected to the sprue, and the sprue is connected to the flow channel.

[0007] The fin assembly consists of several fins arranged in parallel to each other.

[0008] The fins are formed on a substrate and are integral with the substrate.

[0009] The groove has a serpentine structure and is divided into a main flow section and a branch flow section. The branch flow section is composed of several parallel fine flow channels, and each fine flow channel is connected to the main flow section.

[0010] The body and the cover plate are welded together.

[0011] The water inlet includes an inlet and an outlet, which are respectively connected to external water inlet and outlet channels.

[0012] The substrate and fin assembly are an integral structure.

[0013] The substrate has several mounting holes around its perimeter.

[0014] The substrate and fin assembly have an anodized layer on their surfaces.

[0015] The substrate has a water inlet connected to its end or cover plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Heat exchangers for ships meet the heat dissipation requirements of ship control systems, ensure normal equipment operation, prevent malfunctions or performance degradation due to overheating, and solve the problems of low efficiency and easy corrosion of traditional radiators in marine environments. Heat exchangers for ships offer the following advantages:

[0018] 1. High-efficiency heat exchange: Under the action of the fin assembly, the heat generated by the equipment can be directly absorbed, eliminating contact thermal resistance and improving heat transfer efficiency. Then, the heat is conducted to the outside through the cooling water in the flow channel for heat dissipation, thus achieving high-efficiency heat exchange.

[0019] 2. The internal flow channels of the substrate adopt a multi-segment structure to balance the cooling water pressure and flow rate, and at the same time, the heat exchange area is increased by setting multiple fine flow channels in parallel.

[0020] 3. Simple structure and easy installation: It adopts an integrated structure of substrate and fin assembly to achieve reliable and safe high-efficiency heat dissipation. The substrate is fixed to the external enclosed environment with bolts to complete the installation, which is convenient for maintenance and replacement. Attached Figure Description

[0028] The present invention will now be described in detail with reference to the accompanying drawings. However, it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0029] See Figures 1-6 A heat exchange device for ships includes a base plate 1, fin assembly 3, and a sprue. The base plate 1 includes a body and a cover plate. The body has a groove, and one side of the body is fixedly connected to the cover plate, covering the groove and forming a flow channel between the groove and the cover plate. The body and the cover plate are welded by vacuum brazing or friction welding. The other side of the body is machined directly with the fin assembly 3, which is continuous with the body, using a tooth-shaving process or machining. The end of the base plate 1 is connected to the sprue, and the sprue communicates with the flow channel. Alternatively, a hole can be made in the cover plate and connected to the sprue, so that the flow channel communicates with the sprue. The fin assembly 3 is composed of several fins 5 arranged parallel to each other.

[0030] The substrate 1 and the fin assembly 3 are an integral structure. The fin assembly 3 can be formed by machining on the other side of the substrate 1. The internal flow channels of the substrate 1 and the fins 5 are made of a single piece of material to eliminate contact thermal resistance and improve heat transfer efficiency. Several mounting holes 9 are provided around the substrate 1 for easy installation and use with equipment.

[0031] See Figure 5 The substrate 1 has a serpentine groove structure, which increases the flow path and contact area of ​​the fluid, thereby improving heat exchange efficiency. The groove is divided into a main flow section 6 and a branch flow section 7. The branch flow section 7 consists of several parallel fine flow channels 8, each of which is connected to the main flow section 6 to increase the heat exchange area. The end of the serpentine structure is the main flow section 6, and the branch flow section 7 can be arranged alternately with the main flow section 6.

[0032] See Figure 1 The water inlet includes inlet 2 and outlet 4, which are connected to external water inlet and outlet channels respectively.

[0033] The surfaces of substrate 1 and fin group 3 are anodized, which is corrosion resistant and can withstand 168 hours of salt spray test without change, meeting the requirements for use in marine environments.

[0034] Working principle: Inside the sealed environment, the hot air emitted by the equipment is forced to convect and exchange heat through the internal fan and fin assembly 3. The fin assembly 3 directly transfers the heat to the substrate 1. The coolant in the internal flow channel of the substrate 1 is circulated by the pump body to carry away the heat, thereby achieving the purpose of heat dissipation.

[0035] This invention meets the heat dissipation requirements of ship control systems, ensures the normal operation of equipment, avoids malfunctions or performance degradation caused by overheating, and solves the problems of low efficiency and easy corrosion of traditional radiators in marine environments. Under the action of the fin assembly 3, the heat generated by the equipment can be directly absorbed, eliminating contact thermal resistance and improving heat transfer efficiency. The heat is then conducted to the outside through the cooling water in the flow channel for heat dissipation, achieving efficient heat exchange. The flow channel inside the base plate 1 adopts a multi-segment structure to balance the cooling water pressure and flow rate, and the heat exchange area is increased by setting multiple parallel fine flow channels 8. This heat exchange device is highly efficient, safe, and reliable, and has broad application prospects and important practical significance.

[0036] Through the above specific embodiments, those skilled in the art can easily implement this utility model. However, it should be understood that this utility model is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions. Due to space limitations and for the sake of brevity, not all of these combined solutions have been described. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
