Description

Technical Field

[0001] The utility model belongs to the technical field of water tanks and relates to a vehicle-mounted heat exchange water tank. Background Art

[0002] Trucks often encounter long downhill slopes during driving, and the brakes are used continuously. Due to the heavy load of the truck, the brake drum and brake pads produce intense friction, which will cause the temperature of the brake drum and brake pads to rise sharply. If they are not cooled down in time and effectively, it will cause a series of serious traffic accidents such as brake failure and wheel fire.

[0003] To this end, the applicant invented a brake drum with a cooling channel [patent application number is 202420608919.8], including a drum body, an annular water channel is provided in the drum body, a partition is provided in the annular water channel for isolating the annular water channel, and one end of the drum body is provided with two connecting holes respectively connected to the annular water channel. The two connecting holes are arranged adjacent to the partition and are located on different sides of the partition. The cooling water entering from one of the connecting holes goes around the drum body along the annular water channel and then flows out from the other connecting hole, thereby circumferentially cooling the drum body.

[0004] The annular water channel of the brake drum is usually connected in series with the radiator installed on the truck through a pipeline. Under the action of the water pump, the water in the radiator enters the annular water channel through the pipeline to cool the brake drum. The existing radiator connected in series with the annular water channel has a small water storage space. After a small number of cycles, the water in the radiator will become hot. When it runs to the annular water channel, it cannot effectively take away the heat of the brake drum. Therefore, a fan is added on one side of the radiator, but this increases the cost of use. In addition, the radiator capacity is limited and cannot solve the problem of the driver washing his hands. Utility Model Content

[0005] The utility model aims to solve the above problems in the prior art and proposes a low-cost on-vehicle heat exchange water tank.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A vehicle-mounted heat exchange water tank comprises a tank body, a coolant outlet and a heat exchange tube, wherein the tank body is provided with a partition for dividing the tank body into a coolant chamber and a heat exchange chamber, the coolant outlet is communicated with the coolant chamber, the heat exchange tube is located in the heat exchange chamber, the liquid outlet end of the heat exchange tube is communicated with the coolant chamber, and the liquid inlet end of the heat exchange tube extends out of the tank body.

[0008] The cooling channel of the automobile brake drum is connected in series between the coolant outlet and the liquid inlet end of the heat exchange tube. Under the action of the water pump, the coolant enters the pipeline from the coolant outlet, then enters the cooling channel to cool the brake drum, and then flows back to the liquid inlet end of the heat exchange tube through the pipeline. The coolant exchanges heat with the water in the heat exchange chamber in the heat exchange tube, and the coolant with reduced temperature flows back to the cooling liquid chamber from the liquid outlet end of the heat exchange tube. Since the heat exchange tube is set up, it can exchange heat with the water in the heat exchange chamber, which can effectively reduce the temperature of the coolant. It does not need to be used in conjunction with a fan, which reduces the cost of use. The water temperature in the heat exchange chamber can be reduced by replacing the water in the heat exchange chamber or by surface heat dissipation to ensure the heat exchange effect.

[0009] The shape of the box is not limited to cylindrical, rectangular, etc. During manufacturing, in addition to adding a partition in the box, two independent water tanks can also be spliced ​​together, with one water tank serving as a coolant chamber and the other water tank serving as a heat exchange chamber.

[0010] The coolant chamber and the heat exchange chamber are integrated together to facilitate installation and layout.

[0011] In the above-mentioned vehicle-mounted heat exchange water tank, the liquid inlet end of the heat exchange tube passes through the partition and then out of the cavity wall of the cooling liquid cavity. The cooling liquid outlet and the liquid inlet end of the heat exchange tube are located on the same side of the cooling liquid cavity, and the liquid inlet end of the heat exchange tube is arranged higher than the cooling liquid outlet.

[0012] The coolant outlet and the inlet end of the heat exchange tube are arranged on the same side of the coolant cavity, which facilitates the connection of the brake drum cooling pipeline. The coolant outlet is located at the lower part of the coolant cavity, and the inlet end of the heat exchange tube is located at the upper part of the coolant cavity. The coolant flowing back from the cooling channel to the heat exchange tube has little impact on the coolant in the coolant cavity.

[0013] In the above-mentioned vehicle-mounted heat exchange water tank, the tank body is provided with a water inlet and a water outlet respectively connected to the heat exchange chamber, the water inlet is located at the top of the heat exchange chamber, and the water outlet is located at the bottom of the heat exchange chamber.

[0014] When the water temperature in the heat exchange chamber is high, the high-temperature water in the heat exchange chamber can be replaced with normal-temperature water to effectively ensure the heat exchange effect with the heat exchange tube. The water outlet can be used as an interface for the driver to wash his hands. After heat exchange, the heat exchange chamber is filled with hot water, which can be used for washing hands and bathing in winter.

[0015] In the above-mentioned vehicle-mounted heat exchange water tank, a liquid filling port connected to the cooling liquid cavity is provided on the tank body, and the liquid filling port is located at the top of the cooling liquid cavity. The cooling liquid cavity can be replenished with coolant through the liquid filling port as needed. Covers are provided at the liquid filling port and the water filling port.

[0016] In the above vehicle-mounted heat exchange water tank, the volume of the heat exchange chamber is larger than the volume of the coolant chamber. The large-capacity heat exchange chamber can meet the heat exchange demand and the driver's water demand.

[0017] In the above vehicle-mounted heat exchange water tank, the partition is a metal plate. The coolant in the coolant cavity exchanges heat with the water in the heat exchange cavity through the metal plate, thereby improving the heat exchange effect.

[0018] In the above vehicle-mounted heat exchange water tank, the box body is a metal box body. The metal box body has a good heat transfer effect and can achieve the purpose of rapid temperature reduction when in contact with air.

[0019] Compared with the prior art, the vehicle-mounted heat exchange water tank has the following advantages: due to the provision of a heat exchange tube, heat can be exchanged with the water in the heat exchange chamber, which can effectively reduce the temperature of the coolant, and there is no need to use it in conjunction with a fan, thereby reducing the cost of use; the coolant chamber and the heat exchange chamber are integrated together, which is convenient for installation and layout; the drain port serves as an interface for the driver to wash his hands, and after heat exchange, the heat exchange chamber contains hot water, which can be used for washing hands and bathing in winter; the partition and the box body are both made of metal, and have good heat exchange and heat dissipation effects.

DETAILED DESCRIPTION

[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

The outer shape of the tank body 1 is cylindrical or rectangular. A partition 6 is provided inside the tank body 1 for dividing the tank body 1 into a coolant chamber 4 and a heat exchange chamber 5. The coolant chamber 4 and the heat exchange chamber 5 are arranged horizontally side by side. According to actual use requirements, the volume of the heat exchange chamber 5 is 3-10 times the volume of the coolant chamber 4. The large-capacity heat exchange chamber 5 can meet the heat exchange requirements and the driver's water needs.

[0026] like Figure 1 As shown, the coolant outlet 2 is connected to the coolant cavity 4, the heat exchange tube 3 is coiled in the heat exchange cavity 5, the liquid outlet end 31 of the heat exchange tube 3 is connected to the coolant cavity 4, and the liquid inlet end 32 of the heat exchange tube 3 extends from the side of the box body 1 where the coolant outlet 2 is provided, and the liquid inlet end 32 of the heat exchange tube 3 is arranged higher than the coolant outlet 2.

[0027] like Figure 2 As shown, the cooling channel of the automobile brake drum 7 is connected in series between the coolant outlet 2 and the liquid inlet end 32 of the heat exchange tube 3 through the pipeline 9. Under the action of the water pump 8, the coolant enters the pipeline 9 from the coolant outlet 2, and then enters the cooling channel to cool the brake drum, and then flows back to the liquid inlet end 32 of the heat exchange tube 3 through the pipeline 9. The coolant exchanges heat with the water in the heat exchange chamber 5 in the heat exchange tube 3, and the coolant with reduced temperature flows back to the cooling liquid chamber 4 from the liquid outlet end 31 of the heat exchange tube 3.

[0028] The cooling liquid chamber 4 and the heat exchange chamber 5 are integrated together for easy installation and layout. Since the heat exchange tube 3 is provided, heat can be exchanged with the water in the heat exchange chamber 5, the temperature of the cooling liquid can be effectively reduced, and it is not necessary to use it with a fan, thereby reducing the cost of use. The water temperature in the heat exchange chamber 5 can be reduced by replacing the water in the heat exchange chamber 5 or by surface heat dissipation to ensure the heat exchange effect.

The coolant outlet 2 is located at the lower part of the coolant chamber 4, and the liquid inlet end 32 of the heat exchange tube 3 is located at the upper part of the coolant chamber 4. The coolant flowing back from the cooling channel to the heat exchange tube 3 has little influence on the coolant in the coolant chamber 4.

[0030] like Figure 1 As shown, the box body 1 is provided with a water inlet 51 and a water outlet 52 respectively connected to the heat exchange chamber 5, the water inlet 51 is located at the top of the heat exchange chamber 5, and the water outlet 52 is located at the bottom of the heat exchange chamber 5. When the water temperature in the heat exchange chamber 5 is high, the high-temperature water in the heat exchange chamber 5 can be replaced with normal temperature water to effectively ensure the heat exchange effect with the heat exchange tube 3. The water outlet 52 can be used as an interface for the driver to wash his hands. After heat exchange, the heat exchange chamber 5 is filled with hot water, which can be used for washing hands and taking a bath in winter.

[0031] like Figure 1 As shown, the box body 1 is provided with a liquid filling port 41 connected to the cooling liquid chamber 4, and the liquid filling port 41 is located at the top of the cooling liquid chamber 4. According to demand, the cooling liquid can be added to the cooling liquid chamber 4 through the liquid filling port 41. The liquid filling port 41 and the water filling port 51 are both provided with a cover.

[0032] The partition 6 is a metal plate, and the box body 1 is a metal box body. The coolant in the coolant chamber 4 exchanges heat with the water in the heat exchange chamber 5 through the metal plate, thereby improving the heat exchange effect. The metal box body has a good heat transfer effect, and can achieve the purpose of rapid cooling when in contact with air.
