Description

Technical Field

[0001] The present application relates to the technical field of cooling fans, and in particular to a marine cooling fan. Background Art

[0002] Marine cooling fans belong to a type of industrial cooling fans. Marine cooling fans are generally applied to domestic ships or military ships. Compared with the cooling fans used in cold storage or cold chain logistics, marine cooling fans have higher requirements for defrosting effects because the environmental changes at sea are more complex.

[0003] The existing defrosting methods of cooling fans are carried out by electric heating and by using heat medium. Generally, the common defrosting method for small cooling fans is through the heating mode of electric heating tubes. After the electric heating tubes are heated, the heat exchange components in the machine body are heated up. Currently, the heating tubes are also installed on the water receiving tray at the bottom, and the frost layer in the water receiving tray is also defrosted synchronously. For example, the Chinese utility model patent with the authorization announcement number CN216977300U discloses "a cooling fan for cold storage", where the water receiving tray is arranged at the bottom of the housing, and a water receiving tray electric heating wire is arranged in the water receiving tray.

[0004] During the process of the water receiving tray collecting the liquid medium condensed from the air, the liquid medium will continuously drip onto the heating tubes installed in the water receiving tray. As time goes by, the paint surface of the heating tubes is prone to peeling off, reducing the service life and affecting the defrosting effect. Utility Model Content

[0005] In order to improve the defrosting effect, the purpose of the present application is to provide a marine cooling fan.

[0006] A marine cooling fan provided by the present application adopts the following technical solutions:

[0007] A marine cooling fan includes a cabinet, and further includes:

[0008] A first water receiving tray, arranged at the bottom of the cabinet, the first water receiving tray having a first water receiving groove and a plurality of first drain holes communicating with the first water receiving groove;

[0009] A second water receiving tray, arranged at the bottom of the cabinet, the second water receiving tray having a second water receiving groove and a second drain hole communicating with the second water receiving groove, the first water receiving tray being received in the second water receiving groove; and

[0010] At least one heating component, connected to the bottom of the first water receiving tray, the heating component including at least one first heating tube, at least one second heating tube, and a fixing member connecting the first heating tube and the second heating tube;

[0011] The first water receiving tray has a mounting groove at the bottom, the fixing member is arranged in the mounting groove, and the first heating tube and the second heating tube are staggered in the vertical direction.

[0012] By adopting the above technical solution, the first water receiving tray serves as the first water receiving component to receive the liquid medium generated on the surface of the heat exchange component, and the heating component installed at the bottom of the first water receiving tray is used for defrosting. The second water receiving tray can receive the liquid medium flowing down from the first drainage hole of the first water receiving tray, and discharge it through the second drainage hole. In the heating component, since the first heating tube and the second heating tube are staggered in the vertical direction through the fixing member, while the first water receiving tray is defrosted, the space area between the first water receiving tray and the second water receiving tray is heated up and the second water receiving tray can be defrosted at the same time. The heating component is connected by the fixing member and does not need to be installed in the second water receiving tray. This reduces the lasting impact of the liquid medium falling on the heating tube, improves the service life and use effect of the heating tube, and ensures the defrosting effect. Secondly, the upper and lower arrangement of the two water receiving trays allows the defrosting process to be independent and improve the defrosting efficiency.

[0014] A horizontal support portion, two ends of which abut against the side walls of the mounting groove;

[0015] At least one first fixing portion, used to connect the first heating tube, the first fixing portion is disposed on one side of the horizontal supporting portion and extends toward one side of the first water receiving tank; and

[0016] At least one second fixing portion is used to connect the second heating pipe, and the second fixing portion is arranged on the other side of the horizontal supporting portion and extends toward one side of the second water receiving tank.

[0017] By adopting the above technical solution, the two ends of the horizontal support part are fixed by the friction between the side walls of the installation groove, and the heating pipe can be installed on the first fixing part or the second fixing part to achieve flexible installation, which facilitates the overall disassembly and assembly operation. At the same time, the first fixing part and the second fixing part are respectively arranged on both sides of the horizontal support part, so that the corresponding first heating pipe and the second heating pipe can be arranged in a staggered manner and distributed in the vertical space, so that the heating range can be improved, and in order to increase the heating amount, multiple first fixing parts and multiple second fixing parts can be arranged to better improve the defrosting effect.

[0018] Preferably, the fixing member further comprises:

[0019] A vertical support portion, the vertical support portion is connected to the horizontal support portion and is located on the same side as the first fixing portion;

[0020] Wherein, the end of the vertical support portion abuts against the top wall of the mounting groove.

[0021] By adopting the above technical solution and combining with the clamping at both ends of the horizontal support part, after the vertical support part abuts against the top wall of the installation groove, the fixing effect of the fixing part in the installation groove can be further improved, ensuring the stability during the operation of the heating component.

[0022] Preferably, a part of the second fixing part extends out of the installation groove, and the second heating tube protrudes from the bottom of the first water receiving tray.

[0023] By adopting the above technical solution, the second heating tube is fixed on the second fixing part, protrudes from the bottom of the first water receiving tray and faces the second water receiving tray side, so that the vertical distance between the first heating tube and the second heating tube can be increased. Combining with the quantity and height settings of the second fixing part, the heating range can be further improved, and the defrosting effect can be better enhanced.

[0024] Preferably, the first fixing part and the second fixing part have the same structure and both include a clamping groove with an opening on one side, and the first heating tube and the second heating tube are clamped in the corresponding clamping grooves.

[0026] Preferably, a contact sleeve is clamped at the end of the horizontal support part and the vertical support part, and the contact sleeve abuts against the grass groove wall of the installation groove.

[0027] By adopting the above technical solution, using the contact sleeve to replace the clamping and abutting of the horizontal support part and the vertical support part can improve the service life of the entire fixing part. The contact sleeve can be used as a consumable part and can be replaced.

[0028] Preferably, the installation groove is provided with converging parts extending towards each other at the opening.

[0029] By adopting the above technical solution, the setting of the converging parts makes the opening of the installation groove smaller and can prevent the fixing part from detaching from the opening after being connected to the installation groove, better improving the installation stability of the entire heating component and making the defrosting effect better.

[0030] Preferably, the installation groove is opened along the length direction of the first water receiving tray, and the first drainage hole is staggered from the installation groove.

[0031] By adopting the above technical solution, the first drainage hole is staggered from the installation groove, which can prevent the liquid medium from dripping onto the heating tube from the first drainage hole, better improving the service life of the heating tube.

[0032] Preferably, the second water receiving groove has a plurality of guide surfaces inclined towards the second drainage hole side.

[0049] Figure 1 The present invention shows an exploded schematic diagram of a marine air cooler structure, which includes a cabinet 10 and a first water receiving tray 1 and a second water receiving tray 2 installed at the bottom of the cabinet 10. The size of the second water receiving tray 2 is larger than that of the first water receiving tray 1, so that the first water receiving tray 1 can be accommodated in the second water receiving tray 2, and the first water receiving tray 1 and the second water receiving tray 2 are both installed at the bottom of the cabinet 10 by fasteners.

[0050] The first water receiving tray 1 has a first water receiving groove 11 , and a plurality of first drainage holes 12 are provided at the bottom of the first water receiving groove 11 . The first water receiving groove 11 can contain liquid medium generated by condensation on the surface of the heat exchange component arranged in the cabinet 10 , and drain it from the first water receiving groove 11 through the first drainage holes 12 .

[0051] The second water receiving tray 2 has a second water receiving groove 21. The first water receiving tray 1 can be integrally received in the second water receiving groove 21, and the second water receiving groove 21 can hold the liquid medium led out from the first drain hole 12. The bottom of the second water receiving groove 21 has a plurality of inclined diversion surfaces 23. The plurality of diversion surfaces 23 are inclined towards the second drain hole 22 communicating with the second water receiving groove 21. The liquid medium contained in the second water receiving groove 21 can be quickly converged into the second drain hole 22 by the diversion surfaces 23 for discharge. The outlet of the second drain hole 22 is connected to a drain pipe, and the drain pipe can be connected or disconnected from the outlet through a control valve to realize the control of drainage.

[0052] Combined with Figure 2 , at least one installation groove 13 is formed by stamping process at the bottom of the first water receiving tray 1. The installation groove 13 extends along the length direction of the first water receiving tray 1. Each installation groove 13 is provided with a heating component 3. The heating component 3 includes at least one first heating pipe 31, at least one second heating pipe 32 and a fixing member 33. The fixing member 33 is clamped in the installation groove 13 and is used for connecting the first heating pipe 31 and the second heating pipe 32.

[0053] In this embodiment, taking one first heating pipe 31 and one second heating pipe 32 arranged in each installation groove 13 as an example, each installation groove 13 is provided with two fixing members 33 which are respectively clamped into the openings on both sides of the installation groove 13. Of course, the number of fixing members 33 is not limited to the number set in this embodiment. The more the number of fixing members 33, the higher the connection stability of the first heating pipe 31 and the second heating pipe 32.

[0054] Refer to together Figure 3 and Figure 4 , the fixing member 33 includes a horizontal support portion 331, a first fixing portion 333, a second fixing portion 334 and a vertical support portion 332 connected to the horizontal support portion 331. The first fixing portion 333 and the second fixing portion 334 are respectively arranged on one side of the horizontal support portion 331. There is an included angle between the vertical support portion 332 and the horizontal support portion 331. In this embodiment, taking the horizontal support portion 331 and the vertical support portion 332 being at a 90° angle as an example.

[0055] Both ends of the horizontal support portion 331 are in contact with the side wall of the installation groove 13, and the end of the vertical support portion 332 is in contact with the top wall of the installation groove 13. A contact sleeve 336 is clamped at the end of the horizontal support portion 331 and the vertical support portion 332. The contact sleeve 336 is made of a material with high temperature resistance and wear resistance. The contact sleeve 336 is in contact with the installation groove 13 to increase the friction between the whole fixing member 33 and the installation groove 13 to realize their connection.

[0056] In addition, the installation groove 13 has converging portions 131 extending towards each other at the bottom opening. The two converging portions 131 limit the opening of the installation groove 13 and simultaneously inhibit the possibility of the horizontal support portion 331 falling off from the opening of the installation groove 13.

[0057] Both the first fixing portion 333 and the second fixing portion 334 include clamping grooves 335 disposed at the ends, and one side of the clamping groove 335 is open. The first heating pipe 31 is clamped in the clamping groove 335 of the first fixing portion 333, and the second heating pipe 32 is clamped in the clamping groove 335 of the second fixing portion 334. Thus, the first heating pipe 31 and the second heating pipe 32 are arranged in a staggered manner in the vertical direction. Further, the second fixing portion 334 extends out from the opening of the installation groove 13, and the lengths of the first fixing portion 333 and the second fixing portion 334 can be flexibly adjusted according to the power and working conditions, thereby increasing the heating range.

[0058] Combined Figure 5 , after the first water receiving tray 1 and the second water receiving tray 2 are respectively connected to the cabinet 10, a space area 4 is formed between them with a spacing, and this space area 4 can be used to hold a liquid medium. Since the second fixing portion 334 extends out from the opening of the installation groove 13, the second heating pipe 32 can be close to the second water receiving groove 21 for defrosting.

[0059] When installing this marine air cooler, after assembling the cabinet 10 and the heat exchange components, the installation of the first heating pipe 31 and the fixing member 33 is completed in advance. After completion, the fixing member 33 can be installed into the installation groove 13, and then the connection between the second heating pipe 32 and the fixing member 33 is installed. Of course, the installation operations of the first heating pipe 31, the second heating pipe 32 and the fixing member 33 can also be completed in advance, and finally the installation of the second water receiving tray 2 and the cabinet 10 is carried out. During the defrosting operation, the first heating pipe 31 and the second heating pipe 32 generate heat. Since they are arranged in a staggered manner in space, the heating range is increased, effectively improving the defrosting effect. Embodiment 2
