Description

Technical Field

[0001] This utility model belongs to the field of high-temperature heat pump technology, and more specifically, it relates to a cold-heat coupling ultra-large temperature difference series counterflow high-temperature heat pump. Background Technology

[0002] The cold-heat coupling ultra-large temperature difference series counterflow high-temperature heat pump is an advanced heat pump technology. Its characteristics are that it combines cold-heat coupling, ultra-large temperature difference and series counterflow technologies to achieve efficient and energy-saving heat energy conversion and utilization.

[0003] Based on the above, the inventors have discovered the following problems: During the installation and use of current high-temperature heat pumps, it is necessary to install them outdoors, which may cause dust or impurities in the air to adhere to the surface of the heat pump, potentially clogging certain components of the heat pump system, such as filters and fans. These blockages can lead to problems such as insufficient system flow and abnormal pressure, and in severe cases, may cause system failure or shutdown, which is quite inconvenient.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a cold and heat coupled ultra-large temperature difference series counterflow high temperature heat pump in order to achieve a more practical value. Utility Model Content

[0005] The purpose and effect of this utility model of a cold-heat coupling ultra-large temperature difference series countercurrent high-temperature heat pump are achieved by the following specific technical means:

[0006] A high-temperature heat pump with cold and heat coupling, ultra-large temperature difference, series countercurrent flow, includes a mounting base, a heat pump body mounted on the top of the mounting base, a set of connecting pipes mounted on one end of the heat pump body, an installation groove inside the mounting base, a dust cover mounted on the top of the mounting base, a slot on the surface of the dust cover, the bottom end of the dust cover being installed into the interior of the installation groove, and a mechanism for limiting the position of the dust cover inside the mounting base.

[0007] Furthermore, a set of cooling fans is installed at the top of the heat pump body.

[0008] Furthermore, the mechanism for limiting the dust cover includes a connecting rod, the surface of which is fitted with a spring, one end of which is fitted with a locking block, and one end of which extends through the mounting base into the interior of the mounting groove.

[0009] Furthermore, the card block is installed inside the card slot.

[0010] Furthermore, a set of handles is connected to both ends of the mounting base, and one end of each handle passes through the mounting base and connects to the connecting rod inside.

[0011] Furthermore, the surface of the dust cover is provided with several sets of filter screens, including large filter screens and small filter screens, and the large filter screens are installed on the outside of the dust cover.

[0012] Furthermore, the surface of the dust cover is provided with a set of through holes, and one end of the connecting pipe extends through the through holes to the outside.

[0013] Furthermore, a sealing gasket is provided at the contact point between the dust cover and the mounting base.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By utilizing the interlocking mechanism between the locking block and the slot, when installing the dust cover, the operator can first move the connecting rod and locking block by pulling the handle, and then install the bottom end of the dust cover into the installation slot. Releasing the handle will cause the locking block to automatically engage with the slot under the action of the spring, thus limiting the position of the dust cover. The operation is very simple and effectively prevents dust or impurities in the air from adhering to the surface of the heat pump body, indirectly improving dust prevention efficiency. This design also facilitates regular maintenance and cleaning by the operator, greatly increasing its practicality.

[0016] By using a combination of small and large filters, the large filter can effectively prevent some larger impurities in the air, while the small filter can filter out some fine dust, further improving the filtration effect and making it very convenient. Attached Figure Description

[0029] This utility model provides a cold and heat coupled ultra-large temperature difference series countercurrent high temperature heat pump, including a mounting base 1, a heat pump body 7 mounted on the top of the mounting base 1, a set of connecting pipes 3 mounted on one end of the heat pump body 7, an installation groove 6 opened inside the mounting base 1, a dust cover 2 provided on the top of the mounting base 1, a slot 10 opened on the surface of the dust cover 2, the bottom end of the dust cover 2 is installed inside the installation groove 6, and a set of mechanisms for limiting the dust cover is provided inside the mounting base 1.

[0030] A set of cooling fans 8 is installed at the top of the heat pump body 7.

[0031] The mechanism for limiting the dust cover includes a connecting rod 12, on the surface of which a spring 11 is sleeved. One end of the connecting rod 12 is fitted with a locking block 13, and one end of the locking block 13 extends through the mounting base 1 into the interior of the mounting groove 6.

[0032] The locking block 13 is installed inside the slot 10. Through the cooperation between the locking block 13 and the slot 10, when installing the dust cover 2, the operator can first move the connecting rod 12 and the locking block 13 by pulling the handle 5, and then install the bottom end of the dust cover 2 into the installation groove 6. When the handle 5 is released, the locking block 13 will automatically lock into the slot 10 under the action of the spring 11, thereby limiting the position of the dust cover 2. The operation steps are very simple, effectively preventing dust or impurities in the air from adsorbing on the surface of the heat pump body 7, indirectly improving the dust prevention efficiency. This design also facilitates the regular maintenance and cleaning by the operator, greatly increasing its practicality.

[0033] The mounting base 1 is equipped with a set of handles 5 at both ends, and one end of the handle 5 passes through the mounting base 1 and is connected to the connecting rod 12.

[0034] The dust cover 2 has several sets of filter screens 4 on its surface. The filter screens 4 include small filter screens 42 and large filter screens 41, and the large filter screens 41 are installed on the outside of the dust cover 2.

[0036] The dust cover 2 and the mounting base 1 are fitted with sealing gaskets at their contact points.

[0037] The specific usage and function of this embodiment are as follows:

[0038] Before installation and use, the operator needs to inspect the internal components or structure of the heat pump body 7. After the inspection is completed, normal installation and use can proceed. First, after fixing the heat pump body 7, the operator can install the dust cover 2. When installing the dust cover 2, the operator can first move the connecting rod 12 and the locking block 13 by pulling the handle 5. Then, the bottom end of the dust cover 2 is installed into the installation groove 6. When the handle 5 is released, the locking block 13 will automatically lock into the groove 10 under the action of the spring 11, thereby limiting the position of the dust cover 2. The operation steps are very simple, effectively preventing dust or impurities in the air from adsorbing on the surface of the heat pump body 7, indirectly improving the dust prevention efficiency. This design also facilitates regular maintenance and cleaning by the operator, greatly increasing its practicality. At the same time, through the design of the small filter 42 and the large filter 41, the large filter 41 can effectively prevent some larger impurities in the air, while the small filter 42 can filter some fine dust, further improving the filtration effect.
