Description

Technical Field

[0001] The utility model relates to the technical field of airtightness testing of profile-type cold plate heat exchangers, in particular to a novel false flow channel airtightness tooling. Background Art

[0002] The air tightness of the heat exchanger is crucial to the quality of the heat exchanger product. A good heat exchanger should have high air tightness. The air tightness detection method of the heat exchanger is generally simple, and most of them use immersion detection, that is, the heat exchanger is placed in a water pool, and air is inflated into the heat exchanger. The air tightness of the heat exchanger is tested by the presence or absence of bubbles, the frequency of bubble generation, and the location of bubble generation. The air tightness detection method of the heat exchanger is simple, mostly manual operation, and manual intervention is relatively large;

[0003] The existing profile-type cold plate heat exchangers usually have almost no internal air leakage during the air tightness test, but the problem of false flow channel leakage still exists. Therefore, a tooling for detecting false flow channel leakage is added to the process to prevent the outflow of defective parts. Utility Model Content

[0004] The utility model aims to provide a novel false flow channel airtight tooling to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of false flow channel airtight tooling, including a tooling base plate, a clamping structure is provided at one end of the tooling base plate, a product is placed on the end surface of the tooling base plate, and a first limit strip and a second limit strip are symmetrically provided on both sides of the product and fixedly arranged on the end surface of the tooling base plate.

[0006] Further optimized, the clamping structure is arranged at one end of the tooling base plate, including a clamping hand clamp fixedly arranged in the middle of one end of the tooling base plate and a first clamping block arranged at one end of the clamping hand clamp.

[0007] For further optimization, the clamping pliers are symmetrically provided with a first limit block and a second limit block fixed to the end surface of the tooling bottom plate on both sides.

[0008] For further optimization, a positioning block is provided on the other side of the second limiting block away from the clamping pliers.

[0009] For further optimization, a telescopic cylinder is provided on the other side of the first limiting block away from the clamping pliers, and a second clamping block connected thereto is provided at the telescopic end thereof.

[0010] For further optimization, the positioning block and the second pressing block are both provided with sealing silicone at one end close to the product.

[0011] Beneficial Effects

[0012] The new type of false runner airtight tooling provided by the utility model can position and press the product to the end face of the tooling fixture through clamping pliers, positioning blocks and multiple limit strips to perform an airtight test. It can effectively test the problem of false runner airtight failure caused by stirring welding, thereby ensuring the yield of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION

[0014] 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.

[0015] Example

[0016] like Figure 1 As shown, a new type of false flow channel airtight tooling includes a tooling base plate 1, a clamping structure is provided at one end of the tooling base plate 1, a product 2 is placed on the end face of the tooling base plate 1, and a first limit strip 10 and a second limit strip 11 fixedly arranged on the end face of the tooling base plate 1 are symmetrically provided on both sides of the product 2.

[0017] In this embodiment, the clamping structure is arranged at one end of the tooling base plate 1, including a clamping pliers 4 fixedly arranged in the middle of one end of the tooling base plate 1 and a first clamping block 5 arranged at one end of the clamping pliers 4. The product is clamped by using the clamping pliers 4 and the first clamping block 5. In addition, a flexible gasket is provided on the contact surface between the first clamping block 5 and the product to prevent the product from being damaged by the clamping pliers.

[0018] A first limit block 6 and a second limit block 7 are symmetrically arranged on both sides of the clamping pliers 4 and fixed to the end surface of the tooling base plate 1. The limit block on the top positions the product to a corresponding position to avoid test failure.

[0019] A positioning block 12 is provided on the other side of the second limiting block 7 away from the clamping pliers 4 .

[0020] A telescopic cylinder 8 is provided on the other side of the first limit block 6 away from the clamping pliers 4, and a second clamping block 9 connected thereto is provided at its telescopic end. Sealing silicone is provided on the positioning block 12 and the end of the second clamping block 9 close to the product. The second clamping block 9 is driven by the telescopic cylinder to perform an airtight test on the product. In addition, the sealing silicone between the positioning block and the telescopic end of the cylinder can seal the product, thereby performing a sealing test.

[0021] Put the product into the tooling and position it with the limit block and the clamping pliers, then clamp it with the clamping pliers. After starting the cylinder, make it airtight with the sealing silicone and use the airtight equipment to detect the airtightness of the false flow channel.
