Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

As shown in fig. 1 to 5, a heat exchanger core 100 according to an embodiment of the present utility model includes a middle heat exchanger 1, an upper water chamber 2 and a lower water chamber 3, the upper water chamber 2 is disposed on the upper side of the middle heat exchanger 1, a partition 23 dividing the upper water chamber 2 into an upper water inlet chamber 21 and an upper water outlet chamber 22 is disposed in the upper water chamber 2, the upper water inlet chamber 21 and the upper water outlet chamber 22 are both communicated with the middle heat exchanger 1, and the lower water chamber 3 is disposed on the lower side of the middle heat exchanger 1 and communicated with the middle heat exchanger. The upper water chamber 2 has a water inlet 24 communicating with the upper water inlet chamber 21, a water outlet 25 communicating with the upper water outlet chamber 22, and a communication hole 230 communicating with both the upper water inlet chamber 21 and the upper water outlet chamber 22.

When the heat exchanger core 100 of the embodiment of the utility model works, water enters the upper water inlet chamber 21 from the water inlet 24, then flows downwards into the lower water chamber 3 through the intermediate heat exchange body 1, then flows upwards to the upper water outlet chamber 22 through the intermediate heat exchange body 1 and flows out through the water outlet 25. Wherein, the water flowing through the heat exchanger core 100 exchanges heat with the air flow to heat or cool the air flow. When there are bubbles inside the heat exchanger core 100, the bubbles generally float in the upper inlet chamber 21 and the upper outlet chamber 22 due to the light weight of the bubbles relative to the water. The bubbles in the upper inlet chamber 21 and the upper outlet chamber 22 cannot flow downward with the water flow, but can flow at the same height with the water flow. By providing the communication hole 230 communicating with the upper water inlet chamber 21 and the upper water outlet chamber 22 in the upper water chamber 2, the air bubbles floating in the upper water inlet chamber 21 can flow into the upper water outlet chamber 22 directly through the communication hole 230 along with a part of water in the upper water inlet chamber 21, and the air bubbles floating in the upper water outlet chamber 22 can be discharged out of the heat exchanger core 100 through the water outlet 25 along with water flow. Thereby avoiding the water in the heat exchanger core 100 from impacting the bubbles, causing the bubbles to burst and emit larger water flow sound, and further reducing the operation noise of the heat exchanger core 100.

Therefore, the heat exchanger core 100 of the embodiment of the present utility model has advantages of low operation noise, and the like.

Alternatively, as shown in fig. 2, the intermediate heat exchange body 1 includes a first flat tube 11 and a second flat tube 12, where the first flat tube 11 and the second flat tube 12 extend in the vertical direction, two ends of the first flat tube 11 are respectively communicated with the upper water inlet chamber 21 and the lower water chamber 3, and two ends of the second flat tube 12 are respectively communicated with the upper water outlet chamber 22 and the lower water chamber 3.

The water in the upper water inlet chamber 21 flows downwards into the lower water chamber 3 through the first flat pipe 11, then flows upwards into the upper water outlet chamber 22 through the second flat pipe 12 and flows out through the water outlet 25. The middle heat exchange body 1 has simple structure and is convenient to process and manufacture.

Alternatively, as shown in fig. 2 to 5, at least a part of the communication hole 230 is provided to the partition 23.

It will be appreciated that the upper chamber 2 comprises a housing connected to the intermediate heat exchange body 1, a portion of the housing enclosing an upper inlet chamber 21 with a partition 23, and another portion of the housing enclosing an upper outlet chamber 22 with the partition 23. At least a part of the communication hole 230 provided in the partition plate 23 means that: the communication hole 230 is integrally provided in the partition plate 23; or a part of the communication hole 230 is provided in the partition 23 and another part of the communication hole 230 is provided in the housing.

By arranging at least a part of the communication hole 230 on the partition plate 23, holes can be reduced or even avoided from being formed in the outer shell of the water feeding chamber 2, so that the thickness of the outer shell of the water feeding chamber 2 can be set thinner under the condition of ensuring the overall structural strength of the water feeding chamber 2, and the weight and the cost of the heat exchanger core 100 can be reduced.

Alternatively, as shown in fig. 2, the upper side of the partition 23 is provided with a communication hole 230.

As described above, the bubbles generally float on the upper part of the water, i.e., on the upper part of the water in the upper inlet chamber 21 and the upper outlet chamber 22. By providing the communication hole 230 on the upper side of the partition plate 23, bubbles in the upper water inlet chamber 21 flow into the upper water outlet chamber 22 along with water flow through the communication hole 230, and are finally discharged through the water outlet 25 communicated with the upper water outlet chamber 22. Thereby further facilitating the evacuation of air bubbles within the heat exchanger core 100.

Optionally, as shown in fig. 1, the housing of the upper water chamber 2 includes a bottom shell and a top plate 203, the top plate 203 is disposed on the upper side of the bottom shell and connected to the bottom shell, and the bottom shell is connected to the intermediate heat exchanging body 1. A portion of the top plate 203, a portion of the bottom shell and the partition 23 enclose an upper inlet chamber 21, and another portion of the top plate 203, another portion of the bottom shell and the partition 23 enclose an upper outlet chamber 22. A part of the hole wall of the communication hole 230 is formed by the top plate 203.

By forming a part of the hole wall of the communication hole 230 by the top plate 203 so that the communication hole 230 is disposed more toward the upper side of the partition plate 23, the discharge of the air bubbles in the heat exchanger core 100 is further facilitated.

Alternatively, the number of the communication holes 230 is plural, and the plural communication holes 230 are arranged at intervals along the longitudinal direction of the partition 23, wherein the longitudinal direction of the partition 23 is perpendicular to the up-down direction.

For example, the partition plate 23 extends in the left-right direction, the partition plate 23 divides the upper water chamber 2 into the upper water inlet chamber 21 and the upper water outlet chamber 22, and the upper water inlet chamber 21 is located at the rear side of the upper water outlet chamber 22. The plurality of communication holes 230 are arranged at intervals in the left-right direction.

By providing the plurality of communication holes 230, bubbles at different positions of the upper inlet chamber 21 can enter the upper outlet chamber 22 through the adjacent communication holes 230 and be discharged through the water outlet 25, thereby facilitating the discharge of bubbles in the heat exchanger core 100.

Alternatively, the bottom case includes a first side plate 201 and a second side plate 202 disposed opposite to each other along a length direction of the partition 23, the water inlet 24 and the water outlet 25 are disposed on the first side plate 201, and a portion of a hole wall of at least one communication hole 230 is formed by the second side plate 202.

As shown in fig. 2, 3 and 5, the first side plate 201 is disposed on the right side of the second side plate 202, and the water inlet 24 and the water outlet 25 are both disposed on the first side plate 201. The left side of the partition 23 is provided with a first opening 231, a part of the first opening 231 is blocked by the second side plate 202, another part of the first opening 231 is blocked by the top plate 203, the partition 23, the second side plate 202 and the top plate 203 enclose a communication hole 230 through the first opening 231, and at this time, a part of the hole wall of the communication hole 230 is formed by the second side plate 202.

It will be appreciated that in order to ensure that the intermediate heat exchange body 1 is filled with water, water entering through the water inlet 24 of the first side plate 201 will flow towards the second side plate 202 until the upper water inlet chamber 21 is filled, and a portion of the water will flow downwardly into the intermediate heat exchange body 1 during the flow of water. The bubbles in the upper intake chamber 21 are liable to flow to the second side plate 202 with the water flow.

By disposing one of the communication holes 230 close to the second side plate 202, bubbles in the upper inlet chamber 21 easily enter the upper outlet chamber 22 through the communication hole 230 and are discharged, thereby further facilitating the discharge of bubbles in the heat exchanger core 100.

In addition, it will be appreciated that in order to ensure that the water entering from the water inlet 24 of the first side plate 201 fills the upper water inlet chamber 21, the water pressure at the water inlet 24 should be ensured to be high, and by disposing one of the communication holes 230 close to the second side plate 202, such that the communication hole 230 is far from the water inlet 24, even if the water in the upper water inlet chamber 21 flows into the upper water outlet chamber 22 through the communication hole 230, the influence on the water pressure at the water inlet 24 is small, which is beneficial to improving the reliability of the heat exchanger core 100.

Optionally, as shown in fig. 1, 2 and 5, the heat exchanger core 100 further includes a water inlet pipe 4 and a water outlet pipe 5, wherein a portion of the water inlet pipe 4 is inserted into the water inlet 24 and connected to the first side plate 201, and a portion of the water outlet pipe 5 is inserted into the water outlet 25 and connected to the first side plate 201.

Thus, water enters the upper water inlet chamber 21 through the water inlet pipe 4, and water in the upper water outlet chamber 22 flows out through the water outlet pipe 5.

As shown in fig. 2, the upper chamber 2 has a third side plate 204 and a fourth side plate 205 which are disposed opposite to each other in the thickness direction of the partition plate 23, and the first side plate 201, the second side plate 202, the third side plate 204, the fourth side plate 205, and the top plate 203 enclose an upper chamber 2 with an opening facing downward, and the upper chamber 2 communicates with the intermediate heat exchanger 1 through the opening.

Alternatively, at least one communication hole 230 is provided in the middle of the partition 23 in the length direction of the partition 23.

For example, one of the communication holes 230 is provided in the middle of the partition 23 in the left-right direction. As shown in fig. 2, 4 and 5, a second opening 232 is formed in the middle of the partition 23, the top plate 203 seals the second opening 232, and the partition 23 and the top plate 203 enclose a communication hole 230 through the second opening 232.

By providing at least one communication hole 230 in the middle of the partition 23 in the longitudinal direction of the partition 23, the discharge of air bubbles located in the middle of the partition 23 is facilitated with less influence on the water pressure of the water inlet 24.

Alternatively, the dimension of the communication hole 230 in the length direction of the partition 23 gradually increases in the bottom-up direction.

The size of the communication hole 230 in the length direction of the partition 23 increases gradually in the bottom-up direction, so that the risk of bubbles touching the wall of the communication hole 230 when flowing through the communication hole 230 along with water flow can be reduced, thereby reducing the risk of explosion when the bubbles flow through the communication hole 230, and being beneficial to further reducing the operation noise of the heat exchanger core 100.

Alternatively, the equivalent diameter of the communication hole 230 is 3.5mm to 7mm.

It can be understood that the larger the equivalent diameter of the communication hole 230, the less likely to collide with the hole wall of the communication hole 230 to burst when bubbles flow into the upper outlet chamber 22 through the communication hole 230 in the upper inlet chamber 21, thereby avoiding the running noise of the heat exchanger core 100 due to the burst of bubbles; but also reduces the amount of water flowing into the intermediate heat exchange body 1 in the upper water inlet chamber 21, and water needs to be ensured to be filled in the intermediate heat exchange body 1 by increasing the water flow of the water inlet 24, which requires increasing the load of a water pump connected with the heat exchanger core 100 and certainly increases the running cost of the heat exchanger core 100. The smaller the equivalent diameter of the communication hole 230 is, the smaller the amount of water in the upper water inlet chamber 21 directly flows into the upper water outlet chamber 22 through the communication hole 230, so that the amount of water in the upper water inlet chamber 21 flowing into the intermediate heat exchange body 1 is larger, and the heat exchange efficiency of the intermediate heat exchange body 1 can be satisfied under the condition that the load of a water pump connected with the heat exchanger core 100 is smaller, so that the running cost of the heat exchanger core 100 is not excessively high; however, when the air bubbles in the upper water inlet chamber 21 flow into the upper water outlet chamber 22 through the communication holes 230, the air bubbles collide with the walls of the communication holes 230 more easily to burst, and the heat exchanger core 100 is likely to generate operation noise due to the burst of the air bubbles.

Experimental studies have shown that when the equivalent diameter of the communication hole 230 is less than 3.5mm, most of bubbles in the upper inlet chamber 21 flow into the upper outlet chamber 22 through the communication hole 230 to collide with the wall of the communication hole 230 to burst, resulting in loud operation noise of the heat exchanger core 100. When the equivalent diameter of the communication hole 230 is greater than 7mm, the load increase of the water pump connected to the heat exchanger core 100 is large, and the operation cost of the heat exchanger core 100 is significantly increased.

By setting the equivalent diameter of the communication hole 230 to 3.5mm to 7mm, the operation noise of the heat exchanger core 100 can be further reduced while ensuring that the operation cost of the heat exchanger core 100 is low.

Alternatively, at least a portion of the hole wall of the communication hole 230 is arc-shaped.

For example, as shown in fig. 2 to 5, the wall of the right side hole of the communication hole 230 has a circular arc shape, that is, the communication hole 230 has a quarter circle shape as a whole. Of course, in other embodiments, the communication hole 230 may be formed in a semicircular shape, a circular shape, an elliptical shape, or the like.

By setting at least a portion of the hole wall of the communication hole 230 to be arc-shaped, sharp corners existing in the hole wall of the communication hole 230 can be reduced or even avoided, so that when bubbles pass through the communication hole 230 along with water flow and touch the hole wall of the communication hole 230, the risk of explosion of the bubbles can be reduced, and the running noise of the heat exchanger core 100 can be further reduced.

According to the heat exchanger core 100 of the embodiment of the utility model, the communication hole 230 is arranged between the upper water inlet chamber 21 and the upper water outlet chamber 22, so that residual bubbles in the heat exchanger core 100 or bubbles brought in the running process can be utilized by the communication hole 230, and the problem that gas in the heat exchanger core 100 cannot be discharged is solved along with the water flow flowing from the upper water inlet chamber 21 into the upper water outlet chamber 22 through the communication hole 230 directly.

Not only can the exhaust time in the whole car off-line process be saved, but also the water flow sound in the warm core operation process can be avoided, and the new problem caused by the warm core to the current water pump water valve integration is solved.

The heat exchanger of the embodiment of the utility model comprises a shell and a heat exchanger core 100, wherein the heat exchanger core 100 is the heat exchanger core 100 of any embodiment, and the heat exchanger core 100 is arranged in the shell and connected with the shell.

The heat exchanger of the embodiment of the utility model has the advantages of low operation noise and the like because the heat exchanger core 100 of the embodiment of the utility model has the advantages of low operation noise and the like.

The vehicle of an embodiment of the present utility model includes the heat exchanger core 100 of any of the embodiments described above and/or the heat exchanger of any of the embodiments described above. The vehicle may be a pure electric vehicle, a hybrid electric vehicle or a fuel oil vehicle, and the water in the heat exchanger core 100 may be a coolant from an engine.

The heat exchanger core 100 of the embodiment of the utility model has the advantages of low operation noise and the like, so the vehicle of the embodiment of the utility model has the advantages of low operation noise and the like.

When the whole car off-line cooling liquid system is deaerated or deaerated after the after-sales replacement, most of water flow in the upper water inlet chamber 21 enters the middle heat exchange body 1 for internal reference, and the small part of water flow carries the bubbles into the upper water outlet chamber 22 through the communication hole 230 and finally is discharged through the water outlet 25. The degassing efficiency is improved, so that the off-line efficiency of the whole vehicle is improved, and the degassing time after the after-sale replacement is shortened.

When the heat exchanger core 100 is used for heating, the water in the heat exchanger core 100 can separate out air and small bubbles attached to the pipe wall are concentrated in the upper intake chamber 21, in addition, after the water pump water valve of the whole automobile is switched for many times, the air can be possibly introduced into a cooling liquid system of the automobile, and finally, the air is concentrated in the upper intake chamber 21 in a bubble form. Because the bubbles are lighter, the bubbles are difficult to discharge along with the water flow after descending along with the water flow. The water flow impact bubble burst can give out gurgling water flow sound, especially the impact caused by liquid inertia when the car is suddenly braked and turns, and subjective discomfort of the water flow sound can be aggravated. Most of the water in the upper water inlet chamber 21 flows downwards to participate in heat exchange; and the bubbles can directly enter the upper water outlet chamber 22 from the communication hole 230 along with a small part of water and be discharged from the inside of the heat exchanger core 100 together with the main water flow in the upper water outlet chamber 22, thereby improving the water flow sound during heating.

While embodiments of the present utility model have been shown and described above, it should be understood that the above embodiments are illustrative and not to be construed as limiting the utility model, and that variations, modifications, alternatives, and variations of the above embodiments may be made by those skilled in the art without departing from the scope of the utility model.
