Description

Technical Field

[0001] This utility model relates to the field of heat exchanger structure, and in particular to a heat exchanger that is easy to assemble and disassemble. Background Technology

[0002] Heat exchangers have a wide range of applications and are very common in various household appliances, especially in equipment requiring cooling, refrigeration, and heat dissipation, such as refrigerators and air conditioners. Their function is to transfer the heat generated by the equipment through heat pipes, exchanging heat energy between the equipment and the air via heat exchange fins, thereby achieving a cooling effect. Existing heat exchanger structures generally involve inserting heat pipes into holes in the middle of the heat exchange fins for fixation. While this structure is simple, it has many inconveniences. In actual installation, it is very troublesome to install the heat exchange fins neatly and completely onto the heat pipes, usually requiring large assembly equipment platforms, which is very costly. Manual installation is time-consuming and results in poor product quality. After installation, during actual use, due to prolonged exposure inside the equipment and operation in conjunction with a fan, a large amount of dust, lint, and carbon powder accumulates between the heat exchange fins over time. Normal rinsing with water is insufficient for cleaning, making it very inconvenient. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a novel structure of heat exchanger with the advantages of convenient installation and disassembly.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] A heat exchanger that is easy to install and disassemble includes a base, on which heat exchange fins and heat-conducting pipes are disposed. The base is characterized by having a bottom cavity for installing the heat exchange fins at its bottom, and several side grooves for accommodating the heat-conducting pipes on its front and rear sides. The heat exchange fins are divided into main heat exchange fins and secondary heat exchange fins. An opening groove is provided at the bottom of the main heat exchange fin for accommodating the heat-conducting pipes. A protrusion is provided at the top of the secondary heat exchange fin to be inserted into the opening groove for fixing the heat-conducting pipes. A fixing bracket for installing and fixing the main heat exchange fins is provided on the base, and a disassembly bracket for installing and fixing the secondary heat exchange fins is installed at the bottom of the base.

[0006] Furthermore, the fixing frame in this utility model includes a snap-fit ​​groove on the left and right sides of the base for installing the main heat sink, and the snap-fit ​​groove is interference-fitted with the main heat sink.

[0007] Furthermore, the present invention has several opening slots, each opening slot being U-shaped with a downward opening. The heat-conducting pipe is embedded in the opening slot and positioned at the top of the opening slot during installation.

[0008] Furthermore, the base of this utility model is provided with mounting and disassembly grooves on the front and rear sides of its bottom.

[0009] Furthermore, the assembly / disassembly frame of this utility model includes a frame body, the front and rear ends of which are detachably embedded in the assembly / disassembly slots. Screw seats for fastening to the base are provided on the front and rear sides of the frame body. Several crossbars are provided in the middle of the frame body. The crossbars are provided with snap-fit ​​slots for installing secondary heat sinks. The snap-fit ​​slots are interference-fitted with the secondary heat sinks.

[0010] Furthermore, the present invention has a plurality of protrusions, the top of which is a U-shape with an upward opening. When the auxiliary heat sink is installed, the protrusion is inserted into the opening groove and the top of the protrusion is positioned at the bottom of the heat pipe.

[0011] Furthermore, the base of this utility model is equipped with side covers at both the front and rear sections.

[0012] In summary, the advantages of this utility model over the prior art are:

[0013] This invention simplifies the installation and removal of heat pipes by dividing the heat exchange fins into two parts. The main heat sink and the auxiliary heat sink can be separated by opening the mounting bracket, and the heat pipe can be installed or removed between the opening slot and the protrusion. Compared with the existing structure, this invention simplifies the installation and removal process. Both the main heat sink and the auxiliary heat sink can be easily installed or removed from the mounting bracket and the mounting bracket. The assembly process saves a lot of installation costs, and disassembly and cleaning are also very convenient. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] like Figures 1 to 5The present invention preferably provides a heat exchanger that is easy to install and disassemble, including a base 1, on which heat exchange fins 2 and heat conduction pipes 3 are provided. The base 1 has a bottom cavity 4 for installing the heat exchange fins 2, and several side grooves 12 for accommodating the heat conduction pipes 3 are provided on the front and rear sides of the base 1. The heat exchange fins 2 are divided into main heat sinks 21 and secondary heat sinks 22. The main heat sink 21 has an opening groove 5 at the bottom for accommodating the heat conduction pipes 3. The secondary heat sink 22 has a protrusion 6 at the top that is inserted into the opening groove 5 for fixing the heat conduction pipes 3. The base 1 has a fixing bracket 7 for installing and fixing the main heat sink 21, and the base 1 has a mounting bracket 8 for installing and fixing the secondary heat sink 22. The bottom cavity houses the heat exchange fins. When an external fan blows air, the airflow passes through the bottom cavity, carrying away heat from both the main and auxiliary heat sinks. During assembly, the heat pipes are first installed into the side slots. Then, the mounting bracket is connected to the base to install the auxiliary heat sink in place. The heat pipes are pressed into place by the tabs, ensuring full contact between the tabs and the heat pipes for easy heat transfer. Next, each main heat sink is installed onto the mounting bracket. During this process, the opening slot of the main heat sink will fit over the heat pipe and make full contact, facilitating heat transfer. At this point, the main and auxiliary heat sinks are fully fitted with the heat pipes. Disassembly can be performed by reversing the process.

[0021] The mounting bracket 7 of this invention includes snap-fit ​​slots 71 located on the left and right sides of the base 1 for mounting the main heat sink 21. The snap-fit ​​slots 71 are interference-fitted with the main heat sink 21. This interference fit ensures the main heat sink is firmly held in place by the snap-fit ​​slots, preventing accidental dislodgement. Since the main heat sink is typically made of copper sheet, which has a certain degree of flexibility, the interference fit facilitates installation.

[0022] In this invention, several opening slots 5 are provided. Each opening slot 5 is U-shaped with a downward opening. When the heat-conducting pipe 3 is installed, it is embedded in the opening slot 5 and positioned at the top of the opening slot 5. The top of the opening slot has a U-shaped arc edge, ensuring that the heat-conducting pipe is in close contact after installation, thus maintaining the desired heat dissipation effect.

[0023] The base 1 of this invention has mounting and disassembly slots 11 on both the front and rear sides of its bottom. These slots are used for mounting and disassembling the mounting bracket.

[0024] The mounting bracket 8 described in this utility model includes a frame body 81. The front and rear ends of the frame body 81 are detachably embedded in mounting slots 11. Screw seats 82 for fastening to the base 1 are provided on the front and rear sides of the frame body 81. Several crossbars 83 are provided in the middle of the frame body 81. The crossbars 83 have locking grooves 84 for installing secondary heat sinks 22, and the locking grooves 84 are interference-fitted with the secondary heat sinks 22. After embedding the front and rear ends of the frame body into the mounting slots, screws are tightened into the screw seats to install the mounting bracket. Before installation, the secondary heat sink is inserted into the locking grooves 84. The interference fit ensures the secondary heat sink is firmly held in place and will not accidentally come out. Since the secondary heat sink is generally made of copper sheet, which has a certain degree of flexibility, the interference fit makes installation easy. After installation, the secondary heat sink and the main heat sink are aligned and flush.

[0025] In this invention, several protrusions 6 are provided. The top of each protrusion 6 is U-shaped with an upward opening. When the auxiliary heat sink 22 is installed, the protrusions 6 are inserted into the opening groove 5, with the top of the protrusions 6 positioned at the bottom of the heat pipe 3. The top of the protrusion has a U-shaped arc edge, ensuring close contact with the heat pipe after installation, thus maintaining the desired heat dissipation effect.

[0026] In this invention, side covers 13 are installed at the front and rear sections of the base 1. The side covers are detachable and used to shape the edges of the base for installation with other components of the equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
