Description

Technical Field

[0001] This utility model relates to the field of metal bath technology, and in particular to a metal bath heating device based on temperature control. Background Technology

[0002] Metal bath heating devices are commonly used temperature control equipment in laboratories, widely applied in fields such as molecular biology, chemical analysis, and clinical testing. These applications include experiments requiring precise and stable temperature environments, such as enzymatic reactions, PCR pretreatment, sample incubation, and serum coagulation. Their core function is to utilize the high thermal conductivity of the metal medium (usually an aluminum block) to uniformly and rapidly transfer heat to the sample tubes, achieving precise temperature control of the sample.

[0003] Traditional metal bath heating devices typically employ an integrated structure, where the heating module is fixedly connected to the main unit, and the sample well specifications (such as pore size, depth, and arrangement) on the metal block are relatively limited. When users purchase equipment based on their experimental needs, they often need to match the specifications and quantity of sample tubes. If experimental conditions change (such as replacing centrifuge tubes or PCR tubes of different sizes), the existing equipment may no longer meet the requirements, necessitating the purchase of dedicated modules or the entire unit. This results in high operating costs, low equipment utilization, and large storage space requirements. Therefore, a temperature-controlled metal bath heating device is proposed to address these issues. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a temperature-controlled metal bath heating device to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of the present invention provides a metal bath heating device based on temperature control, including a body, a panel, buttons, and a top plate. The front of the body is fixedly connected to the panel, which integrates a digital display screen and has several buttons installed on it.

[0007] A top plate is fixedly connected to the top of the machine body, and several heating elements are fixedly connected to the top of the top plate. The heating elements are bent rods and generate heat through resistance.

[0008] The top surface of the top plate has reserved positions at the four corners, and flanges are detachably connected to the reserved positions via connectors;

[0009] A metal block is fixedly connected to the top of the flange, and the metal block is fitted onto the surface of the heating element;

[0010] The bottom of the metal block has a groove for matching the heating element, and the top surface of the metal block has a plurality of sample holes, which are linearly arrayed on the top surface of the metal block.

[0011] The top surface of the top plate is detachably connected to a top cover, the bottom of the top cover is open, the top cover is transparent, and the top cover covers the top plate and the metal block.

[0012] Preferably, in any of the above solutions, the body and the panel are connected by screws, and the body integrates a temperature-controlled STM32 microcontroller.

[0013] Using the above technical solution: This metal bath device is a laboratory device that achieves precise temperature control through heat transfer from a metal block. It is widely used in experiments that require a stable temperature environment, such as enzyme reactions, PCR pretreatment, and sample incubation.

[0014] The principle of constant temperature and temperature control in this metal bath device is as follows: the temperature detection module, i.e., the sensor, monitors the actual temperature of the metal block in real time and outputs an analog signal (voltage signal); the microprocessor, i.e., the temperature control STM32 microcontroller, compares the actual temperature with the set temperature, calculates the deviation, and outputs adjustment commands; the power adjustment module (relay / SCR) adjusts the power of the heating element according to the command, controls the heat input, and the heating element is embedded in the metal block to ensure efficient heat transfer. The metal block is the heat transfer core of the constant temperature metal bath and directly contacts the sample container (such as centrifuge tube, PCR tube). The metal block is made of aluminum alloy, which is lightweight, has good thermal conductivity, and low cost.

[0015] Preferably, in any of the above embodiments, the internal structure of the machine body integrates a power control module, and a temperature sensor is installed at the corner of the top plate, with the measuring end of the temperature sensor attached to the surface of the metal block to monitor the temperature of the metal block.

[0016] Preferably, in any of the above solutions, the reserved position is threadedly connected to the connector, the connector being a hexagon socket screw, and the connector being inserted into a flange.

[0017] The core structure of this device consists of a top plate, heating element, pre-drilled slots, flange, metal block, and sample holes. The metal block is designed as a modular unit, with the heating element placed directly on top of the top plate.

[0018] Preferably, the metal block is made of aluminum alloy and is integrally welded to the flange, as described in any of the above embodiments.

[0019] The main body of the device integrates a temperature-controlling STM32 microcontroller and a power control module. A panel is fixedly connected to the front of the body, featuring a digital display and multiple buttons for displaying temperature information and setting parameters. A top plate is fixedly mounted on the top of the body, on which several curved heating elements are arranged; these elements generate heat through resistance heating.

[0020] The top plate has pre-drilled slots at its four corners for detachable flange installation via connectors. The flanges are welded to the metal block to form a single, easily replaceable heating module. The metal block is preferably made of aluminum alloy, which is lightweight, has good thermal conductivity, and is low in cost. The bottom of the metal block has a groove that matches the shape of the heating element, allowing the heating element to be embedded for efficient heat conduction. The top surface of the metal block has multiple rows of linearly arrayed sample wells for holding experimental sample containers such as centrifuge tubes and PCR tubes.
