Description

Technical Field

[0001] This utility model belongs to the field of intercooler testing technology, and in particular relates to a device for testing the cooling performance of an intercooler. Background Technology

[0002] The intercooler is a key component of a turbocharged engine, used to cool the high-temperature air compressed by the turbocharger in order to improve the engine's charging efficiency and power performance. According to its cooling method, it can be divided into two types: air-cooled and water-cooled. Air-cooled intercoolers rely on airflow for heat dissipation, while water-cooled intercoolers rely on coolant for heat dissipation.

[0003] At present, the cooling performance testing of intercoolers mainly relies on thermal cycling test chambers. During the test, the intercooler is first placed into the test chamber of the test chamber and connected to the test chamber. Then, the thermal cycling test chamber preheats the test chamber inside the test chamber. After reaching the preset temperature value, the heating action is stopped. At this time, the intercooler is started and works in the high-temperature test chamber. By monitoring the temperature change in the test chamber, the superiority of the cooling performance of the intercooler can be judged.

[0004] The aforementioned thermal cycling test chamber for testing the cooling performance of intercoolers requires the intercooler to be assembled into its test chamber before testing. However, the intercooler's significant weight makes it difficult to move, posing a challenge and requiring considerable physical exertion for workers. Furthermore, the chamber itself is primarily constructed of metal, including the inner walls and surrounding areas. Since metal has high heat transfer efficiency, the cooling effect within the test chamber is influenced by both the intercooler's heat dissipation and the heat transfer through the metal sidewalls. Therefore, the intercooler's cooling performance test results are affected by the heat transfer within the test chamber's metal materials. To address these issues, we provide a cooling performance testing device for intercoolers. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0025] Please see Figure 1-4 This utility model is a cooling performance testing device for an intercooler, including a test chamber 1, a vacuum pump 2, and a switch assembly 3. The vacuum pump 2 can achieve a vacuum effect on the side wall of the test chamber 1, thereby reducing the heat transfer effect of the test chamber 1. The switch assembly 3 can open or close the slot 108 for inputting the intercooler.

[0026] Specifically, the test chamber 1 is equipped with an equipment slot 103 and a test slot 104. A cover 101 is installed on top of the equipment slot 103 and the test slot 104. A controller 102 is embedded in the front side wall of the test chamber 1. A wiring board 105 is embedded in the left side wall of the test slot 104. The wiring board 105 is used for connecting the intercooler and a temperature detector is also installed on it.

[0027] Furthermore, a slot 108 is provided on the right side wall of the test box 1, and a top groove 108a is provided on the upper side wall of the slot 108. A switch assembly 3 is installed in the slot 108. The switch assembly 3 includes a gate 301 inserted into the slot 108. Hydraulic push rods 302 are fixedly installed at both ends of the upper side wall of the gate 301. A mounting plate 303 is provided on the upper side wall of the hydraulic push rods 302. The mounting plate 303 is also fixedly installed in the upper side wall of the top groove 108a. A hollow groove 107 is provided in the side wall of the test chamber 1 corresponding to the test slot 104, and insulation plates 106 are provided on both sides of the hollow groove 107. A vacuum pump 2 is installed on the front side wall of the test chamber 1, and the air inlet end of the vacuum pump 2 passes through the side wall of the test chamber 1 and connects to the hollow groove 107.

[0028] The operation process of this embodiment is as follows: Before assembling the intercooler, the hydraulic push rod 302 first operates and retracts. When the hydraulic push rod 302 retracts, the gate 301 at its end also moves upward in the slot 108, thereby exposing the slot 108. During the heating of the test chamber 1 and the testing of the intercooler, the vacuum pump 2 operates. Since its vacuum end is connected to the hollow groove 107 in the side wall of the test tank 104 in the test chamber 1, it can achieve a vacuuming effect on the hollow groove 107. The side wall of the test tank 104 is also provided with a heat insulation plate 106. The heat insulation plate 106 and the vacuum structure of the hollow groove 107 can improve the heat insulation effect of the test tank 104 and reduce the rate at which the heat of the test tank 104 dissipates to the outside through the side wall of the test chamber 1, thereby reducing the impact of this dissipated heat on the test results of the intercooler. Example 2

[0029] Please see Figure 5Based on embodiment 1, a heating component 4 is also provided. The heat source fan 406 can heat the temperature of the environment inside the test tank 104, and the purification box 401 can purify the gas inside the test tank 1 to avoid the air quality affecting the test results of the intercooler.

[0030] Specifically, a heating component 4 is installed in the equipment slot 103 of the test chamber 1. The heating component 4 includes a purification box 401 fixed on the bottom side wall of the equipment slot 103, and a blower 404 is provided above the purification box 401. A heat source fan 406 is installed in the blower 404.

[0031] Furthermore, the purification chamber 401 is equipped with a purification core inside, and a chamber base 403 is installed on the bottom side wall of the purification chamber 401. The purification chamber 401 is connected to the side wall of the equipment tank 103 through the chamber base 403. A sealing plate 402 is installed on the upper side wall of the purification chamber 401. An air outlet pipe 401a communicating with the test tank 104 is installed on the side wall of the purification chamber 401. An air inlet pipe 402a communicating with the air box 404 is installed on the sealing cover 402. The air box 404 is equipped with a mounting bracket 405, and a heat source fan 406 is installed inside the mounting bracket 405. The upper end of the equipment slot 103 is also connected to the upper end of the test slot 104.

[0032] The operation process of this embodiment is as follows: When in use, the heating component 4 is started, and the heat source fan 406 in the heating component 4 works to draw the gas in the test chamber 1 into the air box 404. During this process, the gas is also heated. Then, the heated gas is input into the purification chamber 401 through the air inlet pipe 402a, so that the gas comes into contact with the purification core in the purification chamber 401, and then is input into the test tank 104 through the air outlet pipe 401a on the side of the purification chamber 401. This cycle is achieved, which can raise the temperature of the environment inside the test chamber 1. Since a temperature detector is also installed on the wiring board 105 of the test tank 104, the temperature inside the test tank 104 is detected in real time by the temperature detector. When the temperature reaches the preset value, the heating component 4 stops working. Example 3

[0033] Please see Figure 6 Based on Embodiments 1 and 2, a feeding assembly 5 is also provided. The feeding assembly 5 can automatically push the intercooler into or out of the test box 1, which greatly reduces the physical exertion of workers during the assembly and handling of the intercooler.

[0034] Specifically, the bottom of the front and rear side walls of the test tank 104 is provided with mounting grooves 109. The feeding assembly 5 includes a side plate 503 fixed in the mounting groove 109. A carrying plate 501 is provided on the inner side of the side plate 503, and a hydraulic push rod 502 is installed at the end of the carrying plate 501.

[0035] Furthermore, the side plate 503 is L-shaped, and grooves 503a are provided on both inner walls of the side plate 503. Slider 501b is provided on both outer walls of the carrying plate 501, and slider 501b is slidably connected to groove 503a. An end plate 501a is fixedly installed at the end of the loading plate 501 facing the equipment tank 103, and the end plate 501a is connected to the telescopic end side wall of the hydraulic push rod 502. The other end of the hydraulic push rod 502 is fixedly installed on the right side wall of the test tank 104.

[0036] The operation process of this embodiment is as follows: After the slot 108 is exposed, the hydraulic push rod 502 is activated again. The hydraulic push rod 502 retracts, and when it retracts, it pulls the carrying plate 501 to slide on the side plate 503 through the end plate 501a, thereby pushing the carrying plate 501 out of the slot 108 position of the test box 1. Then, the intercooler to be tested is slightly lifted and placed on the carrying plate 501. At this time, the hydraulic push rod 502 is activated again, and it extends, pushing the carrying plate 501 and the intercooler placed on it into the interior of the test box 1. Then, the intercooler is connected to the wiring board 105 of the test box 1. During this process, it is not necessary to excessively move the intercooler.
