Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, and particularly relates to a microchannel plate heat exchanger. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Among them, the heat dissipation area of a plate heat exchanger is relatively large, and the heat dissipation path of a microchannel radiator is longer.

[0003] Since the heat dissipation path of a plate radiator is relatively short; while the heat dissipation area of a microchannel radiator is small and it is not easy to assemble, resulting in the problems of relatively low heat dissipation efficiency and troublesome assembly of conventional radiators.

[0004] Therefore, we propose a microchannel plate heat exchanger to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems of relatively low heat dissipation efficiency and troublesome assembly of conventional radiators, and to propose a microchannel plate heat exchanger.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A microchannel plate heat exchanger includes a flow guiding plate. The flow guiding plate includes a plate body, a butt joint pipe and a first ear plate. A threaded hole is opened on the first ear plate. A water channel is opened inside the plate body. A sealing cover is hermetically covered on the front part of the plate body. The opening of the sealing cover is in butt joint and matching with the butt joint pipe. Collars are fixedly connected to both the upper and lower parts of the flow guiding plate. Screws are movably inserted into the collars. Another set of flow guiding plate and sealing cover are turned 180 degrees and sleeved on the screws, so that the internal spaces of the two sets of flow guiding plates and sealing covers are connected. Similarly, the next set of flow guiding plate and sealing cover are installed, so that the flow guiding plates and sealing covers between groups are hermetically butt-jointed with each other, which is convenient for butt-joint assembly to form radiators of different scales. Water is injected into the flow guiding plate through the sealing cover, passes through the flow guiding plate and is injected into another set of flow guiding plate through the sealing cover of another group, so that the water flows along the water channel of the flow guiding plate, thereby enabling the water to dissipate heat outward through the flow guiding plate and the sealing cover along the way, increasing the length of the heat dissipation path, and thus improving the heat dissipation effect.

[0008] Preferably, the sealing cover includes a cover body, a second ear plate and a sealing nozzle. The sealing nozzle is fixedly connected to the lower part of the cover body and penetrates through the cover body. The sealing nozzle of another set of sealing cover is butted with the butt joint pipe, so that the internal space of the butt joint pipe is butted with the internal space of the sealing nozzle, which is convenient for butting multiple sets of flow guiding plates and sealing covers.

[0009] Preferably, the flow guide plate further includes cushion blocks. There are three cushion blocks. The butt joint pipe and the cushion blocks are distributed at the four corners of the rear wall of the plate body, and the cushion blocks are fixedly connected to the plate body. The cushion blocks are used to pad on the sealing covers of the other group, increasing the stability of the butt joint between the flow guide plate and the sealing covers of the other group.

[0010] Preferably, the flow guide plate further includes a sealing ring, and the sealing ring is fixedly connected to the front part of the plate body. Pass an external screw through the first ear plate and the sealing cover, and screw the external screw through the sealing cover into the first ear plate, so that the sealing ring is clamped between the sealing cover and the plate body. The sealing ring is used to seal the flow guide plate and the sealing cover, facilitating the removal of the sealing cover to clean the impurities in the water channel.

[0011] Preferably, the sealing cover further includes reinforcing strips, and the reinforcing strips are evenly and fixedly connected to the front end of the cover body. The reinforcing strips are used to increase the heat dissipation area of the sealing cover and at the same time increase the firmness of the sealing cover.

[0012] Preferably, a clamping groove is formed at the rear part of the cover body. The clamping groove is used to clamp on the front part of the plate body, increasing the sealing performance between the water channel and the sealing cover.

[0013] Preferably, the screw includes a bolt and a nut, and the nut is threadedly installed on the bolt. After sleeving a collar on the bolt, then tighten the nut so that the bolt and the nut compress multiple groups of flow guide plates and sealing covers, facilitating the fixation of multiple groups of flow guide plates and sealing covers.

[0014] In summary, the technical effects and advantages of the present utility model are as follows:

[0015] 1. Flip another group of flow guide plates and sealing covers 180 degrees and sleeve them on the screws, so that the internal spaces of the two groups of flow guide plates and sealing covers are connected. Similarly, install the next group of flow guide plates and sealing covers, so that the flow guide plates and sealing covers between groups are hermetically butted with each other, facilitating the butt joint and assembly to form radiators of different scales.

[0016] 2. Inject water into the flow guide plate through the sealing cover, and pass through the flow guide plate and inject it into another group of flow guide plates through the sealing cover of the other group, so that the water flows along the water channel of the flow guide plate, thereby enabling the water to dissipate heat outward through the flow guide plate and the sealing cover along the way, increasing the length of the heat dissipation path, and thus improving the heat dissipation effect.

[0017] 3. Connect the sealing nozzle of another group of sealing covers with the butt joint pipe, so that the internal space of the butt joint pipe is connected with the internal space of the sealing nozzle, facilitating the butt joint of multiple groups of flow guide plates and sealing covers.

[0018] 4. Pass an external screw through the first ear plate and the sealing cover, and screw the external screw through the sealing cover into the first ear plate, so that the sealing ring is clamped between the sealing cover and the plate body. The sealing ring is used to seal the flow guide plate and the sealing cover, facilitating the removal of the sealing cover to clean the impurities in the water channel. Description of the Drawings
