D-shaped refrigeration pipe

Abstract

The utility model relates to the technical field of D-shaped refrigerating pipes, in particular to a D-shaped refrigerating pipe. According to the technical scheme, the D-shaped refrigeration pipe comprises a D-shaped pipe assembly and further comprises an extending heat dissipation assembly. An extending heat dissipation assembly is arranged in the D-shaped pipe assembly. The heat conduction area of the straight plate substrate is greatly increased through the heat dissipation extension strips on the two sides of the low-speed refrigerant channel, and heat absorbed by the heat dissipation extension strips can be rapidly guided into the high-speed refrigerant channel and the low-speed refrigerant channel in cooperation with the combination of the large-area circulation channel of the high-speed refrigerant channel and the low-speed refrigerant channel. Due to the fact that the high-speed refrigerant channel is large and the refrigerant circulation speed is high, the refrigerant absorbing heat in the low-speed refrigerant channel can be more easily diffused to the high-speed refrigerant channel to be rapidly circulated, the refrigerant circulation speed is increased, and the purposes that the refrigerant circulation speed is increased while heat conduction is rapid are achieved.

Description

Technical Field

[0001] The utility model belongs to the technical field of D-type refrigeration pipes, and particularly relates to a D-type refrigeration pipe. Background Art

[0002] Traditional circular refrigeration tubes, such as galvanized steel tubes and aluminum tubes, are widely used in refrigerator evaporators, but their heat exchange efficiency still needs to be improved. The emergence of D-type refrigeration tubes aims to improve heat exchange efficiency by changing the shape of the tubes and increasing the contact area with the inner tank.

[0003] Because the internal heat transfer area of ​​the medium is relatively small, the internal heat exchange efficiency may be low. Although the D-type tube increases the contact area with the inner tank through the change of shape, the internal refrigerant flow area has not increased significantly, thus limiting the heat transfer efficiency. On the other hand, in order to increase the heat transfer area, the design of a more complex pipe structure may slow the flow rate of the refrigerant in the pipe. This will affect the refrigerant flow efficiency and heat transfer speed, thereby reducing the heat exchange and heat removal efficiency of the D-type refrigeration tube.

[0004] Therefore, in view of the above-mentioned existing D-type refrigeration tube, because its internal medium heat conduction area is small, its internal heat exchange efficiency is low, and the structure with a large heat exchange area has a slow internal refrigerant circulation speed, resulting in the problem of low heat exchange and heat dissipation efficiency of the D-type refrigeration tube, a D-type refrigeration tube can be designed. Utility Model Content

[0005] In order to overcome the problem that the existing D-type refrigeration tube has low heat exchange efficiency due to its small internal medium heat conduction area, and the structure with a large heat exchange area has slow internal refrigerant circulation speed, resulting in low heat exchange and heat removal efficiency of the D-type refrigeration tube.

[0006] The technical solution of the utility model is: a D-type refrigeration tube, including a D-type tube assembly and an extended heat dissipation assembly; the extended heat dissipation assembly is arranged inside the D-type tube assembly; the D-type tube assembly includes a D-type tube, a straight plate substrate, a high-speed refrigerant channel, a low-speed refrigerant channel, and a heat dissipation gap; the extended heat dissipation assembly includes a heat dissipation extension strip and a through hole.

[0007] Preferably, the heat dissipation extension strips on both sides of the low-speed refrigerant channel are used to greatly increase the heat conduction area of ​​the straight plate substrate surface. The large-area circulation channel of the high-speed refrigerant channel is combined with the low-speed refrigerant channel, so that the heat absorbed by the heat dissipation extension strips can be quickly introduced into the high-speed refrigerant channel and the low-speed refrigerant channel. Since the high-speed refrigerant channel has a large channel and a fast refrigerant circulation speed, the refrigerant that absorbs heat in the low-speed refrigerant channel can be more easily diffused to the high-speed refrigerant channel for rapid circulation, thereby increasing the refrigerant circulation speed and achieving the goal of fast heat conduction and accelerated refrigerant circulation speed. This solves the problem of the existing D-type refrigeration tube, which has a small internal medium heat conduction area, resulting in low internal heat exchange efficiency, and the structure with a large heat exchange area has a slow internal refrigerant circulation speed, resulting in low heat exchange and heat dissipation efficiency of the D-type refrigeration tube.

[0008] Preferably, a straight substrate is provided at the lower end of the D-shaped tube, and the D-shaped tube and the straight substrate are connected by hot-melt connection.

[0009] Preferably, a low-speed refrigerant channel is provided on the upper end surface of the straight substrate; heat dissipation extension strips are provided on both sides of the low-speed refrigerant channel, and the heat dissipation extension strips are integrally formed with the straight substrate.

[0010] Preferably, a through hole is provided inside the heat dissipation extension strip, and the through hole passes through the interior of the heat dissipation extension strip in a horizontal direction, and the through hole is connected to the low-speed refrigerant channel and the heat dissipation gap. The through hole is conducive to the refrigerant on both sides of the heat dissipation extension strip to freely pass through the heat dissipation extension strip, so that the heat can be better conducted and dissipated, further increasing the heat dissipation area.

[0011] Preferably, a high-speed refrigerant channel is provided above the low-speed refrigerant channel, and the high-speed refrigerant channel is provided on the inner side of the D-type tube through the front and back. Since the high-speed refrigerant channel has a large channel and a fast refrigerant circulation speed, the refrigerant that absorbs heat in the low-speed refrigerant channel can more easily diffuse to the high-speed refrigerant channel for rapid circulation, thereby increasing the circulation speed of the refrigerant and achieving the goal of fast heat conduction and accelerated refrigerant circulation speed.

[0012] Preferably, heat dissipation gaps are provided between the heat dissipation extension strips, and the heat dissipation gaps are connected to the high-speed refrigerant channels. The heat dissipation gaps are used for the penetration and circulation of refrigerant to increase the heat dissipation area.

[0013] Preferably, the high-speed refrigerant channel is connected to the low-speed refrigerant channel, which effectively improves the heat conduction of the refrigerant between the high-heat zone and the low-heat zone, making the heat conduction and heat dissipation more uniform and efficient.

[0014] Beneficial effects of the utility model:

[0015] 1. The existing D-type refrigeration tube has a small internal medium heat conduction area, which makes its internal heat exchange efficiency low, and the structure with a large heat exchange area has a slow refrigerant circulation speed, resulting in the problem of low heat exchange and heat removal efficiency of the D-type refrigeration tube; the heat dissipation extension strips on both sides of the low-speed refrigerant channel are used to greatly increase the heat conduction area of ​​the straight plate substrate, and the combination of the large-area circulation channel of the high-speed refrigerant channel and the low-speed refrigerant channel allows the heat absorbed by the heat dissipation extension strips to be quickly introduced into the high-speed refrigerant channel and the low-speed refrigerant channel. In addition, since the high-speed refrigerant channel has a large channel and a fast refrigerant circulation speed, the refrigerant that absorbs heat in the low-speed refrigerant channel is more easily diffused to the high-speed refrigerant channel for rapid circulation, thereby improving the refrigerant circulation speed and achieving the goal of fast heat conduction and accelerated refrigerant circulation speed; it solves the problem of the existing D-type refrigeration tube having a small internal medium heat conduction area, which makes its internal heat exchange efficiency low, and the structure with a large heat exchange area has a slow refrigerant circulation speed, resulting in low heat exchange and heat removal efficiency of the D-type refrigeration tube;

[0016] 2.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See also Figure 1-3 The utility model provides an embodiment: a D-type refrigeration tube, including a D-type tube assembly 1, and also including an extended heat dissipation assembly 2; the extended heat dissipation assembly 2 is arranged inside the D-type tube assembly 1; the D-type tube assembly 1 includes a D-type tube 101, a straight plate substrate 102, a high-speed refrigerant channel 103, a low-speed refrigerant channel 104, and a heat dissipation gap 105; the extended heat dissipation assembly 2 includes a heat dissipation extension strip 201 and a through hole 202.

[0023] See also Figure 1-3 In this embodiment, a straight substrate 102 is provided at the lower end of the D-shaped tube 101, and the D-shaped tube 101 and the straight substrate 102 are hot-melt connected; a low-speed refrigerant channel 104 is provided on the upper end surface of the straight substrate 102; heat dissipation extension strips 201 are provided on both sides of the low-speed refrigerant channel 104, and the heat dissipation extension strips 201 and the straight substrate 102 are integrally formed; a through hole 202 is provided inside the heat dissipation extension strip 201, and the through hole 202 passes through the interior of the heat dissipation extension strip 201 in the horizontal direction, and the through hole 202 is connected to the low-speed refrigerant channel 104 and the heat dissipation gap 105; a high-speed refrigerant channel 103 is provided above the low-speed refrigerant channel 104, and the high-speed refrigerant channel 103 passes through the inner side of the D-shaped tube 101 from front to back.

[0024] See also Figure 1-3 In this embodiment, a heat dissipation gap 105 is provided between the heat dissipation extension strips 201 , and the heat dissipation gap 105 is connected to the high-speed refrigerant channel 103 ; the high-speed refrigerant channel 103 is connected to the low-speed refrigerant channel 104 .

[0025] During operation, the heat dissipation extension strips 201 on both sides of the low-speed refrigerant channel 104 are used to greatly increase the heat conduction area of ​​the straight plate substrate 102. The combination of the large-area circulation channel of the high-speed refrigerant channel 103 and the low-speed refrigerant channel 104 allows the heat absorbed by the heat dissipation extension strips 201 to be quickly introduced into the high-speed refrigerant channel 103 and the low-speed refrigerant channel 104. In addition, since the high-speed refrigerant channel 103 has a large channel and a fast refrigerant circulation speed, the refrigerant that absorbs heat in the low-speed refrigerant channel 104 is more easily diffused to the high-speed refrigerant channel 103 for rapid circulation, thereby increasing the refrigerant circulation speed and achieving the goal of fast heat conduction and accelerated refrigerant circulation speed. This solves the problem of the existing D-type refrigeration tube, which has low internal heat exchange efficiency due to its small internal medium heat conduction area and slow internal refrigerant circulation speed due to the structure with a large heat exchange area.

[0026] Next, the through holes 202 facilitate the refrigerant on both sides of the heat dissipation extension strip 201 to freely pass through the heat dissipation extension strip 201, so that the heat can be better conducted and dissipated, further increasing the heat dissipation area.

[0027] Through the above steps, the heat conduction area of ​​the straight plate substrate 102 is greatly improved through the heat dissipation extension strips 201 on both sides of the low-speed refrigerant channel 104, and the large-area circulation channel of the high-speed refrigerant channel 103 is combined with the low-speed refrigerant channel 104, so that the heat absorbed by the heat dissipation extension strips 201 can be quickly introduced into the high-speed refrigerant channel 103 and the low-speed refrigerant channel 104. Since the high-speed refrigerant channel 103 has a large channel and a fast refrigerant circulation speed, the refrigerant that absorbs heat in the low-speed refrigerant channel 104 can be more easily diffused to the high-speed refrigerant channel 103 for rapid circulation, thereby increasing the circulation speed of the refrigerant and achieving the goal of fast heat conduction and accelerated refrigerant circulation speed, thereby avoiding the problem of low heat exchange efficiency of the existing D-type refrigeration tube due to its small internal medium heat conduction area and slow internal refrigerant circulation speed of the structure with a large heat exchange area.
