Description

Technical Field

[0001] This utility model relates to the field of computer equipment technology, and in particular to a self-heating computer chassis. Background Technology

[0002] A Chinese utility model patent with publication number CN209343254U, entitled "A Computer Chassis with Good Heat Dissipation Performance," describes a system where, when a large amount of heat is generated inside the chassis, a micro water pump is activated to deliver coolant from the water-cooling tank to the cooling pipes. The coolant inside the cooling pipes absorbs heat from inside the chassis through a curved design, while simultaneously flowing back into the water-cooling tank for cyclical heat dissipation. A cooling fan then expels the internal heat. However, the aforementioned cooling pipes are only installed on the inner wall of the chassis and do not directly contact the CPU (Central Processing Unit), the main heat source, resulting in inadequate heat dissipation. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a self-cooling computer case with good heat dissipation effect.

[0004] To achieve the above objectives, the technical solution adopted by the self-heating computer case of this utility model is as follows: A self-cooling computer case includes a case body, a motherboard mounted on the inner wall of the case body, a CPU mounted on the motherboard, a heat exchanger attached to the outer side of the CPU, the heat exchanger being fixedly connected to the motherboard, a water-cooled pump connected to the inlet of the heat exchanger via a first cooling water pipe, the water-cooled pump being installed inside the case body, the outlet of the water-cooled pump being connected to the first cooling water pipe, a second cooling water pipe connected to the inlet of the water-cooled pump, a third cooling water pipe connected to the second cooling water pipe, the third cooling water pipe being coiled in a serpentine shape around the outer wall of the case body, and the third cooling water pipe being connected to the outlet of the heat exchanger via a fourth cooling water pipe.

[0005] Preferably, the heat exchanger has a copper shell, with an inlet pipe connector at the inlet end for connecting to the first cooling water pipe, and an outlet pipe connector at the outlet end for connecting to the fourth cooling water pipe.

[0006] Preferably, the outer side of the housing is fitted with multiple heat dissipation fins, and the bottom sides of the heat dissipation fins are connected by annular support feet. The annular support feet fix the multiple heat dissipation fins to form a heat dissipation sleeve, and the inner wall of the heat dissipation sleeve has a groove for storing the third cooling water pipe.

[0007] Preferably, the top of the heat sink is provided with a bracket, which includes round tubes on both sides of the top of the heat sink fins. The round tubes are used in conjunction with annular support feet to fix the heat sink fins. Each end of the round tube is provided with a handle, which connects the two round tubes into one unit.

[0008] Compared with the prior art, this utility model has the following advantages: 1. The water-cooled pump, the first cooling water pipe, the heat exchanger, the second cooling water pipe, the third cooling water pipe, and the fourth cooling water pipe constitute the coolant circuit, which carries the heat generated by the main heat source, the CPU, to the outside of the case, thereby improving the heat dissipation effect.

[0009] 2. A heat dissipation sleeve is also attached to the outside of the enclosure to increase the heat dissipation area and further improve the heat dissipation effect. Attached Figure Description

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0019] like Figure 1-7As shown, a self-cooling computer case includes a case body 1. A motherboard 11 is mounted on the inner wall of the case body 1, and a CPU 12 is mounted on the motherboard 11. A heat exchanger 2 is attached to the outer side of the CPU 12. The heat exchanger 2 is a copper shell fixed to the motherboard 11. A water inlet connector 21 is welded to the water inlet end of the copper shell, and a water outlet connector 22 is welded to the water outlet end of the copper shell. The water inlet connector 21 is connected to a water-cooling pump 4 through a first cooling water pipe 3. The water-cooling pump 4 is installed at the bottom of the inner cavity of the case body 1. The water-cooling pump 4 is prior art. The water outlet end of the water-cooling pump 4 is connected to the first cooling water pipe 3, and the water inlet end of the water-cooling pump 4 is connected to a second cooling water pipe 5. The second cooling water pipe 5 is connected to a third cooling water pipe 6. The third cooling water pipe 6 is a copper pipe. One end of the third cooling water pipe extends into the case body and connects to the second cooling water pipe. The main body of the third cooling water pipe 6 is coiled in a serpentine shape around the outer wall of the case body. The other end of the third cooling water pipe 6 extends into the case body and connects to the water outlet connector 22 through a fourth cooling water pipe 7. A water-cooled pump, a first cooling water pipe, a heat exchanger, a second cooling water pipe, a third cooling water pipe, and a fourth cooling water pipe constitute a coolant circuit. For ease of connection, the first, second, and fourth cooling water pipes are flexible pipes. Multiple heat dissipation fins 81 are fitted onto the outside of the housing 1. Annular support feet 82 pass through the bottom sides of the heat dissipation fins, and the annular support feet 82 fix the multiple heat dissipation fins 81 to form a heat dissipation sleeve 8. A groove 83 is opened on the inner wall of the heat dissipation sleeve to store the third cooling water pipe. A bracket 84 is set on the top of the heat dissipation sleeve. The bracket 84 includes round tubes 841 on both sides of the top of the heat dissipation fins 81. The round tubes 841 cooperate with the annular support feet 82 to fix the heat dissipation fins 81. Handles 842 are welded to both ends of the round tubes 841, and the handles 842 connect the two round tubes 841 into one unit. The bracket, heat dissipation fins, and annular support feet are all made of aluminum alloy. The heat dissipation fins are brazed onto the bracket and annular support feet to form a heat dissipation sleeve, which is used to increase the heat dissipation area of ​​the third cooling water pipe and the housing.

[0020] The specific working process and principle of this utility model are as follows: The water-cooling pump 4 is started, and the coolant enters the copper casing through the first cooling water pipe 3. After exchanging heat with the CPU, the coolant travels through the second and third cooling water pipes to the outside of the casing 1, and is discharged to the outside through the heat dissipation fins 81. It then returns to the water-cooling pump 4 through the fourth cooling water pipe, and the cycle continues. This utility model uses the water-cooling pump, the first cooling water pipe, the heat exchanger, the second cooling water pipe, the third cooling water pipe, and the fourth cooling water pipe to form a coolant circuit. This circuit carries the heat generated by the CPU, the main heat source, to the outside of the casing, and the heat is quickly dissipated to the outside through the heat dissipation fins, thereby improving the heat dissipation effect.
