Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooler technology, and more specifically, to a portable sampling cooler. Background Technology
[0002] Sampling coolers are instruments used for cooling steam and water samples in boiler rooms or power plants. Boiler water and steam are typically at high temperatures, making direct sampling and measurement impossible. Therefore, cooling is necessary before sampling to ensure testing accuracy.
[0003] Currently, sampling coolers on the market include a cooling water tank and several coils. The sample liquid is cooled as it passes through the cooling water tank along the coils, and finally the cooled sample liquid is output. However, the water flow in the cooling water tank is relatively stable, and the contact between the sample liquid and the coolant is limited when it is in the coils. If the temperature of the input sample liquid is too high, the cooling may not be sufficient, and the output liquid temperature may not meet the testing standards. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a portable sampling cooler with better cooling effect.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A portable sampling cooler includes a housing, a top cover mounted on the housing, a coil mounted on the top cover, an outlet and an inlet connected to the housing, an impeller rotatably mounted on the inlet of the housing, the impeller blades being inclined, a bracket fixed to the bottom of the housing, and a plurality of self-locking casters evenly mounted on the bracket.
[0007] The present invention is further configured such that: the water outlet is located at one end of the housing near the top cover, and the water inlet is located on the bottom surface of the housing.
[0008] The present invention is further configured such that: the water inlet is funnel-shaped, the large-diameter end of the funnel-shaped water inlet is connected to the housing, and the impeller is coaxial with the water inlet.
[0009] The present invention is further configured such that: a plurality of retaining rings are provided on the inner wall of the housing, the outer ring of the retaining ring is fixed on the housing, a gap is preset between the inner ring of the retaining ring and the coil, and the height of the inner ring is higher than the height of the outer ring.
[0010] The present invention is further configured such that: the bracket is frustoconical in shape, and the small-diameter end of the bracket is fixed to the bottom of the housing and the side wall of the housing.
[0011] The beneficial effects of this utility model are:
[0012] 1. An impeller is installed at the water inlet. The impeller blades are inclined. Cooling water enters the housing from the water inlet. When the water flows through the impeller, it will drive the impeller to rotate, thereby promoting the flow of cooling water in the housing, increasing the contact between the cooling water and the coil, and thus improving the heat exchange effect.
[0013] 2. Several baffle rings are provided on the inner wall of the shell. A certain gap is left between the inner side of the baffle ring and the coil. The inner side of the baffle ring is inclined upward. When the cooling water moves upward, it is restricted by the baffle ring and its flow direction is changed, which increases the liquid flow near the coil and improves the cooling effect.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0020] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.
[0021] Please see Figure 1-3 The present invention provides the following technical solution:
[0022] A portable sampling cooler includes a housing 1, a top cover 2 mounted on the housing 1, a coil 3 mounted on the top cover 2, and an outlet 4 and an inlet 5 connected to the housing 1. The outlet 4 is located at one end of the housing 1 near the top cover 2, and the inlet 5 is located on the bottom surface of the housing 1. Cooling water enters from the bottom of the housing 1, rises to the outlet 4 at the top, and is discharged, ensuring the interactive flow of cooling water inside the housing 1 and ensuring the heat exchange effect.
[0023] The inlet 5 is funnel-shaped, and the large-diameter end of the funnel-shaped inlet 5 is connected to the housing 1. An impeller 6 is rotatably mounted on the opening. The impeller 6 is coaxial with the inlet 5, and the blades of the impeller 6 are set at an angle. When the cooling water enters the housing 1 from the inlet 5, the liquid flow impacts the blades of the impeller 6, thereby driving the impeller 6 to rotate. When the impeller 6 rotates, it agitates the water stored in the housing 1, promotes the convection between cooling water, and increases the contact rate between the cooling water and the coil 3, thereby improving the cooling effect.
[0024] Several retaining rings 7 are provided on the inner wall of the housing 1. The outer ring of the retaining ring 7 is fixed on the housing 1. There is a pre-set gap between the inner ring of the retaining ring 7 and the coil 3. The height of the inner ring is higher than the height of the outer ring. When the cooling water passes through the retaining ring 7, it is blocked by the retaining ring 7, which changes the liquid flow direction and increases the liquid flow rate through the coil 3, thereby improving the cooling effect.
[0025] A bracket 8 is fixed to the bottom of the housing 1. The bracket 8 is truncated cone-shaped. The small diameter end of the bracket 8 is fixed to the bottom of the housing 1 and the side wall of the housing 1. The large diameter end of the bracket 8 faces downward and is evenly equipped with several self-locking casters 9, which can be moved easily and facilitate sampling.
[0026] Specifically, an impeller 6 is provided at the water inlet 5. The blades of the impeller 6 are inclined. Cooling water enters the housing 1 from the water inlet 5. When the water flows through the impeller 6, it will drive the impeller 6 to rotate, thereby promoting the flow of cooling water in the housing 1, increasing the contact between the cooling water and the coil 3, and thus improving the heat exchange effect.
[0027] Several baffle rings 7 are provided on the inner wall of the housing 1. A certain gap is left between the inner side of the baffle ring 7 and the coil 3. The inner side of the baffle ring 7 is inclined upward. When the cooling water moves upward, it is restricted and its flow direction is changed after passing through the baffle ring 7, which increases the liquid flow near the coil 3 and improves the cooling effect.
