Description

Technical Field

[0001] The utility model relates to the technical field of automobile radiators, in particular to a low-temperature radiator for a passenger car. Background Art

[0002] The car radiator consists of three parts: the water inlet chamber, the water outlet chamber and the radiator core. The coolant flows in the radiator core, and the air passes outside the radiator. The hot coolant cools down as it dissipates heat to the air, and the cold air heats up as it absorbs the heat dissipated by the coolant.

[0003] Prior art, such as publication number: CN206830293U discloses a low-temperature radiator for a passenger car, characterized in that it includes a left water chamber, a right water chamber and a radiator core, wherein the left water chamber and the right water chamber are respectively connected to the left and right ends of the radiator core, the left water chamber is provided with a water inlet, and the right water chamber is provided with a water outlet. The utility model enables the lateral flow inside the radiator to fully exchange heat, thereby improving the heat dissipation effect; it can control the intake air temperature after supercharging and improve the intake air temperature uniformity, and effectively shorten the cooling pipeline, thereby effectively improving the response speed of the turbocharger.

[0004] In summary, the current low-temperature radiator still has the following defects during installation and use at the user end:

[0005] When it is in use, heat is dissipated solely by the radiator's own coolant and heat exchange with the outside air. After long-term use, the radiator continuously radiates heat to the outside, causing the temperature of the radiator's installation location to gradually increase, which in turn drives the temperature of the surrounding air to increase. At this time, the heat exchange effect is greatly reduced when exchanging heat with the air, and the heat dissipation effect is poor. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the inventors conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0007] Specifically, the technical problem to be solved by the utility model is: to provide a low-temperature radiator for a passenger car to solve the problem that the current radiator, when in use, only relies on the coolant of the radiator itself and heat exchange with the outside air to achieve heat dissipation. After long-term use, the radiator continuously radiates heat to the outside, causing the temperature of the installation position of the radiator to gradually increase, which will drive the temperature of the surrounding air to increase. At this time, the heat exchange effect is greatly reduced when exchanging heat with the air, resulting in poor heat dissipation effect.

[0008] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0009] A low-temperature radiator for a passenger vehicle comprises a heat dissipation core, an outer protective shell is installed on the outer wall of the heat dissipation core, and an auxiliary heat dissipation component is installed on the outer wall surface of the outer protective shell;

[0010] The auxiliary heat dissipation component includes an air-cooled heat dissipation body installed on the rear side of the heat dissipation core, and a water-cooled heat dissipation body installed on both sides of the heat dissipation core, and the spray end of the water-cooled heat dissipation body is located between the air-cooled heat dissipation body and the heat dissipation core.

[0011] As an improved technical solution, the water-cooled heat dissipation body includes two side frames welded to both sides of the outer protective shell, a spray pipe is arranged between the side frames on both sides, and the spray pipe can move vertically, and a row of atomizing nozzles are installed on the inner side of the spray pipe.

[0012] As an improved technical solution, a connecting pipe A is installed at the water inlet end of the side of the spray pipe, a clip is welded at the lower position toward the outside of the right side frame, and a connecting pipe B is fixedly installed on the right side frame by the clip. A metal hose is installed between the water inlet end of the connecting pipe A and the water outlet end of the connecting pipe B, and the water inlet end of the connecting pipe B is connected to the water outlet end of the water pump.

[0013] As an improved technical solution, a screw rod is rotatably installed inside the side frame on the left side through a bearing, and a guide rod is welded inside the side frame on the right side. Linkage protrusions are provided on the outer wall surfaces of the screw rod and the guide rod, and the spray pipe is fixed between the two linkage protrusions. A threaded hole threadedly connected to the screw rod is penetrated at the top of the linkage protrusion on the left side, and a sliding hole sliding with the guide rod is penetrated at the top of the linkage protrusion on the right side.

[0014] As an improved technical solution, a support block is welded at a lower position on the inner surface of the right side frame, a servo motor is installed on the top of the support block, a driving gear is installed on the driving end of the servo motor, and a transmission gear meshing with the driving gear is sleeved on the lower position of the outer wall surface of the screw rod.

[0015] As an improved technical solution, the air-cooled heat dissipation body includes two groups of L-shaped mounting frames, and the two L-shaped mounting frames in the same group are respectively welded to the top and bottom of the outer protective shell, and a dual-fan heat dissipation fan is installed between the two L-shaped mounting frames in the same group.

[0016] As an improved technical solution, support pads are welded on both sides of the L-shaped mounting frame, and the inner sides of the support pads are welded to the outer wall surface of the outer protective shell.

[0017] After adopting the above technical solution, the beneficial effects of the utility model are:

[0018] 1. In the utility model, the double-fan cooling fans on both sides of the rear of the heat dissipation core continuously blow air to the outer wall of the heat dissipation core to dissipate heat, so as to accelerate the heat dissipation effect of the radiator. At the same time, water mist is directly sprayed onto the outer wall of the heat dissipation core, and the heat dissipation effect of the radiator is further accelerated by spraying water on the heat dissipation core. Moreover, while spraying water for cooling, the air cooling continuously blows air to the heat dissipation core to dissipate heat, which will accelerate the evaporation of water mist, and the evaporation will take away heat, which will further improve the heat dissipation effect of the heat dissipation core, thereby ensuring that when the radiator is running continuously, its temperature remains stable and the heat dissipation effect is good.

[0019] 2. The utility model drives the spray pipe to move up and down reciprocatingly under the vertical thread transmission of the screw rod and the linkage protrusion, and the atomizing nozzle moves accordingly. When the atomizing nozzle performs vertical upgrading activities, the heat dissipation core will be sprayed and cooled more comprehensively, ensuring the comprehensiveness and uniformity of the heat dissipation of the heat dissipation core.

Example 1

[0032] Reference Figure 1-5, which is the first embodiment of the utility model, provides a low-temperature radiator for a passenger car, the low-temperature radiator for a passenger car comprises a heat dissipation core 1, and connecting pipes are installed at the water inlet and outlet of the heat dissipation core 1, an outer protective shell 2 is installed on the outer wall of the heat dissipation core 1, and an auxiliary heat dissipation component 3 is installed on the outer wall surface of the outer protective shell 2;

[0033] The auxiliary heat dissipation component 3 includes an air-cooled heat dissipation body 31 installed on the rear side of the heat dissipation core 1, and a water-cooled heat dissipation body 32 installed on both sides of the heat dissipation core 1, and the spray end of the water-cooled heat dissipation body 32 is located between the air-cooled heat dissipation body 31 and the heat dissipation core 1.

[0034] The water-cooled heat dissipation body 32 includes two side frames 321 welded on both sides of the outer protective shell 2. A spray pipe 324 is arranged between the side frames 321, and the spray pipe 324 can move vertically. A row of atomizing nozzles 325 are installed on the inner side of the spray pipe 324.
